To setup a cofferdam dewatering system, including boring, pump installation and outflow pipework and drainage tanks etc, typical rates are... • Small 2 hole system, for an overrun tunnel, with a single drilling rig takes about 7 - 10 days to get up and running. • A larger system, with 10 - 15 holes, for a station type cofferdam will take in the region of 3 weeks with 2 rigs. This can be speeded up with the use of more rigs to reduce the well boring times. A typical rate of 2.5 days per pump installation can be used to calculate detailed pumping arrangements. The water level can be dropped in a "closed cofferdam" within a 6 to 8 hour period for a 25,000 m2 cofferdam with a 2 m water level reduction. For smaller closed areas it will take only a few hours at most to reduce the water level by 2.5 - 3 metres. Recharge System - Average well depth of say 55 m deep, not into rock, 9 wells in 10 days or 1.11 days/no with an additional 4 - 5 days to connect pipework and recharge backup tanks etc. Dewatering Task / Description

Spoil By Barge Removal / Transportation Of Spoil By Barge: The size, getting material to the facility, location and movement restrictions of the barge loading facilities are critical to production. A 2,000 m3 flat bottom barge, could easily be loaded 1.5 times per day, with a planned allowance of 2 no movements per day for example... • 1,000 m3 barge, filled in 9.5 hrs = 2 movements/day • 1,500 m3 barge, filled in 6.5 hrs = 3.5 movements/day

Spoil By Conveyor Removal / Transportation Of Spoil By Conveyor: The size and location of the conveyor are critical to production and should be sized according to the most critical peaks in excavation. • There are the following parameters to select... Max excavation per hour
185 m3/hr
Assume belt size
600 mm
Assume conveyor trough angle 20 degrees • From the above you read off specific parameters from the suppliers table... Recommended belt speed
150 m/min
Angle of repose for dry sand 35 degrees Angle of surcharge
20 degrees
• You must then read off, from the manufacturers tables the conveyor capacity... Cross-sectional area of load
0.02979 m2
At a speed of 150 m/min gives 268 m3/hr • Assume a bulking factor for excavated sane = 15%, and assume 50 minutes work per hour to allow for blockages and maintenance etc... • 268 x 85% x 50/60 = 190 so therefore capacity of conveyor = 190 m3 per hour = OK. Hong Kong Airport Express Station conveyor was capable of 11,500 m3/week.

Bored Piling Pre-Drilling - Site Investigation • Pre-boring will be carried out at each location to ascertain the target founding level. • Rotary rig drilling operations incorporate the use of a steel core that is used when a core sample is required. Another type of boreing is called “Wash Bore” or “Percussive Bore” which simply means that a bore is flushed out and is used when no soil sample is required. Typical rates are... Type of Strata

With a standard rig, working a 12 hour shift, a typical output rate of 66 hrs/hole/rig is possible. • As-Built Information. On Central Reclamation, Contract UA11/91, borehole drilling completed with the following results... 1. 2. 3. 4.
Average depth of 61.15 m, total depth of 428 m Average rock socket depth of 4.65 m The durations ranged from 4 to 8 days Average of 5.85 days, total duration of 41 days.
The Target Founding level • This is defined as the required socket into the bedrock, which is defined as moderately decomposed rock grade III or better with a core recovery greater than 85% (allowable bearing capacity of 5 mPa). The continuity of the founding rock is demonstrated by continuing the pre-bored hole a maximum of 5 metres or 3 times the pile diameter, whichever is the greater. • The cores are logged, stored and photographed and submitted together with proposed founding levels for approval. Setting Out
Before starting excavation at the pile position the following steps are taken:
http://www.planningplanet.com/print/book/export/html/422384
11/3/2014
Page 49 of 100
• Survey and record the existing ground level at the pile position • Setout the pile location from the reference points and in order to monitor the position of the steel casing, control pins are usually established at two orthogonal positions, offset from the centre of the pile. Pile Tolerances • In the case of out of position casings, adjustment can be made to keep the vertical alignment and plan position within the limits of no more than 75 mm off-centre on plan position and not deviating by more than 1:75 from the vertical axis. Pile Excavation / Casings • The shaft of the pile is excavated within a temporary steel casing with an outside diameter of say approximately 200 - 300 mm greater than the pile diameter. The casing is used mainly in areas of unstable ground and are driven using hydraulic casing oscillator attached to a crawler crane or a casing vibrator. • Shaft excavation is carried out using a single or double hammer grab supported by crawler crane. The steel casing toe is kept in front of the excavation level until it is 0.5 metres above the pile cut-of level. The pile shaft is often flooded with bentonite or water and excavation proceeds to the top of the CDG. • Excavation then proceeds by reverse circulation drilling (RCD) using large diameter drilling heads with special rock cutters and flushing by air lift. Bentonite or water levels are always maintained above the ground water level to ensure stability of the shaft. Calculation Of Bored Pile Construction / Excavation Time • Piling times can be reduced by the use of service cranes for reinforcement and concreting activities. • An additional extended shift would often be required for certain piles, as would RCD down-time. • Forecast construction times can be derived by using output rates (hours per item)...

Note - due to the required plant assembly and operation times, 4 days is the minimum possible pile construction time for any situation. Methods For Overcoming Obstructions • If the obstruction is shallow (ie 0 to 2.5 m below ground level) a backhoe-breaker will be used to form a suitable hole. • Where the obstructions are located at greater depths an oversized temporary casing is driven by the oscillator to the top of the obstruction. • If the obstruction is above water level a hand operated air hammer is used, a typical rate of = 0.8 m/hr • If below water level a down the hole hammer or heavy chisel supported by crawler crane will be used, a typical rate of = 0.5 m/hr • If a concrete “plug” is required to provide a well formed shaft wall when an obstruction or excessive overbreak or fault is encountered...

Cleaning of Pile Base • The hole of the pile shaft is cleaned using an airlift until the water becomes clean or negligible particles in suspension is discharged. Reinforcement Cages • Cages are constructed in suitable sections, usually in the order of 12 m long, complete with sonic tubes and coring tubes. • Fabrication, 12 m long cage with 6 no fixers... Fabricate 1 cage
2.5 hrs
Total cages required
5 no
Overall Fabrication Time 12.5 hours Steel Stanchion Fabrication and Installation • Stanchions are usually fabricated off-site and delivered in sections. Prior to installation the sections are welded together to form the complete stanchion. Stanchion sizes are usually in the region of 525 mm x 525 mm. • With an average length of say 28 m, the welding time would be around 5 days and are tested by an ultrasonic weld test and an MPI test. • After the installation of the reinforcing cage in to the shaft the stanchion will be lifted until it hangs vertical. It is then lowered into the excavation and clamped into position. Concreting • Pile concreting is carried out under water by "tremie" techniques maintaining the water or bentonite head inside the casing at or above existing ground water level. The tremie tube (250mm) is withdrawn as concreting proceeds ensuring a minimum concrete head of 2 metres above the top of the tremie tube. Sequence Of Piling • The sequence of construction of piles is chosen in such a manner that no damage can be caused to nearby piles still under construction or recently concreted (i.e. less than 3 days). • On a 12 metre grid, a normal layout would mean say having two non-worked on piles between each open excavation in the longitudinal direction (ie a 36 metre spacing) thus allowing room for the crane etc and a lesser spacing of every other pile being worked on (ie a 24 metre spacing). Pile Testing • The workability of concrete is tested on site by measuring the slump and temperature of concreting at the time of discharge into the pile shaft. Laboratory tests are carried out in order to check the strength of the placed concrete. A number of test cubes are made and tested at 7 and 28 days.

• Coring Test - Certain piles selected by the Engineer will be cored their full depth. The depth of cores into the base material (rock) will usually be at least 600 mm. Cores are placed in correct order and relative position in core boxes which clearly mark the depths of cores. The cores are usually photographed and submitted to the Engineer. The testing of the coring will provide additional information about the quality of the concrete as well as the condition of the interface between concrete and rock. • Sonic Logging Test - In order to test the quality of the concrete as well as the integrity of the pile in its overall length and pile toe condition sonic core testing is used. Sonic tubes are installed with the reinforcement cage in order to allow the lowering of the signal transmitter and signal receiver probe down the bottom of the pile. These tubes are sealed at the bottom. • Vibration Tests - This test determines the pile length and shape and the overall pile concrete quality. This is a specialist test.
Contigous Piling Principles of Construction Often known as "Colcrete" piling, which is a type of trade name. Usually replaced by diaphragm walling methods. Essentially typical bored piles, or down-the-hold bored piles, are constructed with a spacing such that each pile is virtually touching the next. These are constructed on a hit-and-miss basis. After a suitable length of these piles are in place (often 9 piles or so) a smaller drilling rig follows on behind placing the "colcrete" piles. A small diameter shaft, often 100 mm or so, is drilled on the external face of the pile wall close to the interection between the two main piles. This excavated pile is fitted with a grout tube and backfilled with gravel. The pile is then grouted and forms a seal between the adjacent piles. This type of pile wall can be constructed with either a standard reinforcement cage or a "H" pile. Info below achieved on project in Bermonsey, London - Sept 2010 1 rig, 600dia contig piles, 12-15m deep, 12No per day (average), 15No per day (max) Rule of thumb based on Hit 1, Miss 3 = 8.5l/m day per rig. Labour: 1 Rig driver, 1 banksman, 1 conc pump operative, 3 x steel fixers, 1 x 360 driver Plant: 1x rig, 1x mini 360 exc, 1x 6m3 mixer, 1x pump, Deliveries: 4 - 5No 6m3 wagons per rig per day (av 2m3 per pile) Mobilisation: 1 day (Allow for 2 days) Next trade - Excavate and blind around piles (for ring beam) - start 7 elasped days after last piles in the run are complete (4 working and 7 elasped days after piling start based on Hit 1 miss 3 method and 12No/d). 34 linear metres released for Groundworker to start. All piles 600mm in dia. No smaller piles or grout tubes used as described in the post by technical development. The face of the basement wall will be faced with a single skin of blockwork at a later date (non critical). Method: Hit 1, Miss 3

Usually at 3 m horizontal centres and can only be worked on with 5 - 6 m spacings. So a hit and miss method must be adopted, giving a significant programme constraint.
Grouting Operations Grouting Vertical Grout Curtain Application of grout curtain. A typical rate of 6.20 hrs/m run.
Hand Dug Caissons Principles Of Construction This type of "pile wall" is typical employed in areas where headroom or proximity to buildings restricts the use of large diameter bored pile drilling rigs, or where the wall is to be located very close to an existing structure. These are very time consuming and in allot of areas no-longer allowed as an acceptable safe construction method. Stringent air monitoring and safety isses are adhered to during the construction of the caisson. An electric chain block and hoist structure is maintained at the pile head for access and egress of both materials and operatives. Site Investigation / Advanced works Advanced grouting is often carried out around the group of caissons in order to reduce water inflow into the caisson area and provide adequate safety factor against base heave failer. Grouting of the area will also restrict ground settlement due to changes in the water table during caisson construction. A 75 mm diameter grout hole is drilled to 2 m belowthe specified toe of the caisson. On completion of drilling, a 40 mm inside diameter PVC, Tube-a-Manchette (T-A-M) grout tube will be installed to the bottom of the grout hole. The tube is usually perforated at 300 mm intervals with each perforation being covered by a tightly fitting rubber sleeve to act as one way valves. The grout hole is often backfilled with gravel and then pumped with grout to the specified pressures etc.. After each stage of grouting the T-A-M will be flushed with water to allow future grouting as necessary. The slightly conical excavation core is carried out by hand and a formwork erected and concrete placed in the void between the excavation and the internal formwork. Excavation down to the next level then begins. Excavation Of Caissons All excavation is carried out with air tools and shovels etc. Material is loaded into a 0.2 m3 drum skip. Hand excavation to a depth not exceeding 1 metre. Fix a suitably braced 3 segmented tapered shutter, fix reinformcement and pour concrete to fill all voids between the external face of the lining and the earth face. This operation is undertaken continously until the founding level is reached. Steel Reinforcement Reinformcement is placed either in prefabricated cages or directly erected in side the bores, depending on headroom and caisson access conditions. In some instances a steel "H" beam is installed in place of a reinforcement cage. Concreting Concrete is cast in place in one continuous operation using the tremmie pipe method, up to cutt-off level. The concrete is generally not vibrated.

Secant Piling Principles Of Construction • Often known as "Benoto" piling, which is a type of trade name. Usually replaced by diaphragm walling methods. • Essentially typical bored piles, or down-the hold type bored piles, are constructed with a spacing slightly smaller than the chosen diameter of the piles. Once a suitable length of piling has been completed, the "holes" are filled with a similar bored pile which intersects and "bites" into the two previously constructed piles. • Usuall these piles are strengthened with a steel "H" pile, rather than the typical reinforcement cages used in standard bored piling. As-Built Examples • Large diameter circular secant pile cofferdam. • Structure consisting of 1,200 mm diameter secant piles to a depth of 20 which then stepped into 900 mm contiguous piles for a further 20 m depth. Each pile was probed to 10 m depth in advance. A total of 255 number piles were constructed. • The "cofferdam" had a 1.4 m deep concrete base slab with a concrete lining to the walls. • An intermediate concrete roof slab was placed to form an underground box structure. • Overall construction time 12 weeks (Heathrow Express).

Escalator Installation Modular Design Escalators Packages The escalator trusses are usually delivered in 1.6 m cubes, which include the internal workings etc. Normally 3 to 4 sections go to make up a standard escalator (an 11 m rise), however sizes and lengths vary greatly. Delivery Implications The largest single element is the nose piece which is approximately 1.8 m wide, 3 m long and 2.5 m high. This section weight 1,500 kg. The other truss sections weight only 1,000 kg at most. The maximum weight of an entire escalator (10 m rise) is estimated at 15,000 kg. It is usual to being the escalators in from the top landing and lower the whole truss down into its final position. Power supply being 415 volt 3 phase hard wired, T&C may be done with temporary supplies. Typical Project Strategy Sequence /timing of works: • • • • • • •
16 wks = Develop concept design / submit for approval. 12 wks = Prepare preliminary design / submit for approval. 60 wks = Manufacture, test & site delivery, in conjunction with completion of final design. 4 wks = Initial delivery placing and connection of truss sections. 12-16 wks = Install escalators and commission. 12 wks = Test running of escalators. 12 wks = Trial running of escalators / System Operational.
Typical Escalator Installation Sequence Timing of single escalator: • • • • • • • • •
1 wks = Assemble sections and truss position, align, level. 6 wks = Escalator contractor "stop work" period, to allow ABWF contractor to complete surrounding finishes. 5 wks = Final escalator installation, "Phase B" decking installation and glazing etc. 0 wks = Escalator Power-On required. 2 wks = Test performance "Phase C" prior to escalator Test Running. 2 wks = Full load test "Phase D" of escalator. 1 wks = Final test "Phase E" 1 wks = EMSD Inspection of installation. 1 wks = "Phase F" inspection.

Fibre Cables There are 4 phases to laying fibre cables - The laying of the duct, the pulling of the fibre cable, the splicing/terminating of the cable and the testing of the cable. The production rate for the laying of the duct will be as any similar small diameter pipe and dependent on the location and linear distance. The cable pulling phase has less to do with the length of the pull and much more to do with the number of pulls required ie draw pit to draw pit distance is less important than the number of times the cable pulling operation is started and stopped. Production is therefore the number of pulls per day. The installers will generally attempt to install the cable from termination point to termination point in one day. Depending on the environment, an assumption of one pull a day is conservative and 2 a day being more optimistic. Crew sizes are small, 3/4 operatives. The termination is obviously a speciallist job and likely to be carried out by different small crew than the pulling of the cable. The duration is dependent on the number of fibres in the cable, but an assumption of one day per location and another day for testing at that location is reasonable.

Stone Cladding External Stone Walls Various stone finishes are available... Polished / Tooled = Highly reflective finish. The full colour and grain of the stone becomes visible. A poished fiish seals the pores and gives a good weather and chemical protection. Honed = Very smooth finish without reflections to show the full colour of the stone. Flamed = Produced by applying a high-temperature flame to the surface ofthe stone. This flame fractures the surface crystals, leaving a rough textured finish. Sequence of operations... Each wall stone is individually numberd to correspond to theshop drawings. The setting out line is established and metal brackets and subframe is installed in accordance with the initial setting out line. Prior to drilling a cover meter is employed to check the cover on the concrete reinforcement. Each stone is individually supported and restrained. Typical wall panel size 0.75 m2/stone. • • • • • • • • •

Petrochemical Oil & Gas Rates & Build Times:
Pipeline Construction Pipe welding is not that straight forward. You have a number of welding passes to take into consideration, then NDT and finally hydrotesting. I worked on a pipeline construction project in Iraq and used the following formulae to work out duration for the welding. The average welder can complete about 140 inches of weld per hour in ordinary 1/4 inch wall line pipe. Therefore, to find the output duration per day you would need to: Number of welds per hour is equal to = ((140/((diameter of pipe - in inches)*3.14))). This gives you an hourly rate of pipeline joints per hour. Times this by the number of hours in the shift to give the daily rate. You can work out how many sections in the run by dividing the run by pipeline length (typically 12m). Then divide this answer by the answer to the welds per hour. This will give you the outline duration for the welding. The welding runs normally follow each other so add half a day lag for each pass (1 day extra). Increase the overall duration by the estimated time to string the pipeline. NDT can happen while the welding is ongoing (obviously on different sections of the pipeline). Add a day overlap from the welding finish to complete NDT. Depending upon the length, include a day to fill the pipeline for Hydrostatic Testing, a day to test and a day to drain. Then you will need to add in a day for hook up. The welding duration will decrease if you have more than 1 team completing the task. We included an in country overhead factor which reduced productivity by 40% to allow for the heat (it was anything upto 60 degrees in the desert in summer), they did a lot of work before the sun came up etc. Overall, this rule of thumb worked very well. Obviously, you will be rounding up rather than rounding down. Additional... I am involved in a number of pipelines across India and when they deploy automatic welding they can cover 500m a day on 30inch pipe. Its a bit slower when you are going over a mountain range.

Floating Track Slab Pre-cast concrete blocks that support standard steel tracks. They are used to reduce noise and vibration as the pre-cast track slab blocks are placed on resin pads (4 no per unit), held in place by fixed side and end restraint blocks. • Side restraints, 0.8 m long, 12 no/day = 9.6 m/day • Resin pads, 10 no/day = 10.0 m/day • FST Units, 5 no/day = 10.0 m/day The above rates were achieved with a 6 man team, but could have been be speeded up by 200 300 % if a works train was available to hoist the units into place. The above was done with a "A" frame and chain hoist.

Cone Fracture Rock Breakage Penetrating Cone Fracture Rock Breakage. Tradename of "SunBurst" from Australia. State of the art, non-explosive chemical rock breakage technology for close proximity excavation applications in mining and civil engineering. Explosive system, cycle time of 6 mins, giving 0.33 m3 each explosion. A typical rate of 10 No cycles per hour, giving 3.3 m3/hr/rig. However, tests have shown differing results... Fresh granite of class 1 strength - One hole in the floor, yielding 0.15 m3 of rock. If more holes had been injected, a yield of 0.5 - 1.0 m3 would be expected. Moderately fresh igneous rock of class 2 strength - Three holes in a sloping trench, in adjacent locations, yielding 2.6 m3 of rock for each hole. Moderately weathered volcanic rock of class 3 strength - Two holes in the floor, in separate locations, yielding 1.2 1.5 m3 of rock for each hole.

To setup a cofferdam dewatering system, including boring, pump installation and outflow pipework and drainage tanks etc, typical rates are... • Small 2 hole system, for an overrun tunnel, with a single drilling rig takes about 7 - 10 days to get up and running. • A larger system, with 10 - 15 holes, for a station type cofferdam will take in the region of 3 weeks with 2 rigs. This can be speeded up with the use of more rigs to reduce the well boring times. A typical rate of 2.5 days per pump installation can be used to calculate detailed pumping arrangements. The water level can be dropped in a "closed cofferdam" within a 6 to 8 hour period for a 25,000 m2 cofferdam with a 2 m water level reduction. For smaller closed areas it will take only a few hours at most to reduce the water level by 2.5 - 3 metres. Recharge System - Average well depth of say 55 m deep, not into rock, 9 wells in 10 days or 1.11 days/no with an additional 4 - 5 days to connect pipework and recharge backup tanks etc. Dewatering Task / Description

Material Weights Wagon sizes and tonnage capacities vary and should be taken into consideration. • • • •
Rock = 2.5 T/m3 Concrete = 2.4 T/m3 Landfill / CDG = 1.9 T/m3 Sand = 1.8 T/m3
Spoil By Barge Removal / Transportation Of Spoil By Barge: The size, getting material to the facility, location and movement restrictions of the barge loading facilities are critical to production. A 2,000 m3 flat bottom barge, could easily be loaded 1.5 times per day, with a planned allowance of 2 no movements per day for example... • 1,000 m3 barge, filled in 9.5 hrs = 2 movements/day • 1,500 m3 barge, filled in 6.5 hrs = 3.5 movements/day

Spoil By Conveyor Removal / Transportation Of Spoil By Conveyor: The size and location of the conveyor are critical to production and should be sized according to the most critical peaks in excavation. • There are the following parameters to select... Max excavation per hour
185 m3/hr
Assume belt size
600 mm
Assume conveyor trough angle 20 degrees • From the above you read off specific parameters from the suppliers table... Recommended belt speed
150 m/min
Angle of repose for dry sand 35 degrees Angle of surcharge
20 degrees
• You must then read off, from the manufacturers tables the conveyor capacity... Cross-sectional area of load
0.02979 m2
At a speed of 150 m/min gives 268 m3/hr • Assume a bulking factor for excavated sane = 15%, and assume 50 minutes work per hour to allow for blockages and maintenance etc... • 268 x 85% x 50/60 = 190 so therefore capacity of conveyor = 190 m3 per hour = OK. Hong Kong Airport Express Station conveyor was capable of 11,500 m3/week.

Deep Compaction Essentially required in order to reduce expected ground settlement and to protect underground utilities / structures etc. • Deep compaction by 350 mm dia Vibroflot, 3 m centres in sand. • Working on 12 hour basis, a vibroflot will achieve an output of 3-4,000 m3/shift (5,000 m3/day has been achieved in an extended shift).

Bored Piling Pre-Drilling - Site Investigation • Pre-boring will be carried out at each location to ascertain the target founding level. • Rotary rig drilling operations incorporate the use of a steel core that is used when a core sample is required. Another type of boreing is called “Wash Bore” or “Percussive Bore” which simply means that a bore is flushed out and is used when no soil sample is required. Typical rates are... Type of Strata

With a standard rig, working a 12 hour shift, a typical output rate of 66 hrs/hole/rig is possible. • As-Built Information. On Central Reclamation, Contract UA11/91, borehole drilling completed with the following results... 1. 2. 3. 4.
Average depth of 61.15 m, total depth of 428 m Average rock socket depth of 4.65 m The durations ranged from 4 to 8 days Average of 5.85 days, total duration of 41 days.
The Target Founding level • This is defined as the required socket into the bedrock, which is defined as moderately decomposed rock grade III or better with a core recovery greater than 85% (allowable bearing capacity of 5 mPa). The continuity of the founding rock is demonstrated by continuing the pre-bored hole a maximum of 5 metres or 3 times the pile diameter, whichever is the greater. • The cores are logged, stored and photographed and submitted together with proposed founding levels for approval. Setting Out
Before starting excavation at the pile position the following steps are taken:

• Survey and record the existing ground level at the pile position • Setout the pile location from the reference points and in order to monitor the position of the steel casing, control pins are usually established at two orthogonal positions, offset from the centre of the pile. Pile Tolerances • In the case of out of position casings, adjustment can be made to keep the vertical alignment and plan position within the limits of no more than 75 mm off-centre on plan position and not deviating by more than 1:75 from the vertical axis. Pile Excavation / Casings • The shaft of the pile is excavated within a temporary steel casing with an outside diameter of say approximately 200 - 300 mm greater than the pile diameter. The casing is used mainly in areas of unstable ground and are driven using hydraulic casing oscillator attached to a crawler crane or a casing vibrator. • Shaft excavation is carried out using a single or double hammer grab supported by crawler crane. The steel casing toe is kept in front of the excavation level until it is 0.5 metres above the pile cut-of level. The pile shaft is often flooded with bentonite or water and excavation proceeds to the top of the CDG. • Excavation then proceeds by reverse circulation drilling (RCD) using large diameter drilling heads with special rock cutters and flushing by air lift. Bentonite or water levels are always maintained above the ground water level to ensure stability of the shaft. Calculation Of Bored Pile Construction / Excavation Time • Piling times can be reduced by the use of service cranes for reinforcement and concreting activities. • An additional extended shift would often be required for certain piles, as would RCD down-time. • Forecast construction times can be derived by using output rates (hours per item)...

Note - due to the required plant assembly and operation times, 4 days is the minimum possible pile construction time for any situation. Methods For Overcoming Obstructions • If the obstruction is shallow (ie 0 to 2.5 m below ground level) a backhoe-breaker will be used to form a suitable hole. • Where the obstructions are located at greater depths an oversized temporary casing is driven by the oscillator to the top of the obstruction. • If the obstruction is above water level a hand operated air hammer is used, a typical rate of = 0.8 m/hr • If below water level a down the hole hammer or heavy chisel supported by crawler crane will be used, a typical rate of = 0.5 m/hr • If a concrete “plug” is required to provide a well formed shaft wall when an obstruction or excessive overbreak or fault is encountered...

5 no
Overall Fabrication Time 12.5 hours Steel Stanchion Fabrication and Installation • Stanchions are usually fabricated off-site and delivered in sections. Prior to installation the sections are welded together to form the complete stanchion. Stanchion sizes are usually in the region of 525 mm x 525 mm. • With an average length of say 28 m, the welding time would be around 5 days and are tested by an ultrasonic weld test and an MPI test. • After the installation of the reinforcing cage in to the shaft the stanchion will be lifted until it hangs vertical. It is then lowered into the excavation and clamped into position. Concreting • Pile concreting is carried out under water by "tremie" techniques maintaining the water or bentonite head inside the casing at or above existing ground water level. The tremie tube (250mm) is withdrawn as concreting proceeds ensuring a minimum concrete head of 2 metres above the top of the tremie tube. Sequence Of Piling • The sequence of construction of piles is chosen in such a manner that no damage can be caused to nearby piles still under construction or recently concreted (i.e. less than 3 days). • On a 12 metre grid, a normal layout would mean say having two non-worked on piles between each open excavation in the longitudinal direction (ie a 36 metre spacing) thus allowing room for the crane etc and a lesser spacing of every other pile being worked on (ie a 24 metre spacing). Pile Testing • The workability of concrete is tested on site by measuring the slump and temperature of concreting at the time of discharge into the pile shaft. Laboratory tests are carried out in order to check the strength of the placed concrete. A number of test cubes are made and tested at 7 and 28 days.

• Coring Test - Certain piles selected by the Engineer will be cored their full depth. The depth of cores into the base material (rock) will usually be at least 600 mm. Cores are placed in correct order and relative position in core boxes which clearly mark the depths of cores. The cores are usually photographed and submitted to the Engineer. The testing of the coring will provide additional information about the quality of the concrete as well as the condition of the interface between concrete and rock. • Sonic Logging Test - In order to test the quality of the concrete as well as the integrity of the pile in its overall length and pile toe condition sonic core testing is used. Sonic tubes are installed with the reinforcement cage in order to allow the lowering of the signal transmitter and signal receiver probe down the bottom of the pile. These tubes are sealed at the bottom. • Vibration Tests - This test determines the pile length and shape and the overall pile concrete quality. This is a specialist test.
Contigous Piling Principles of Construction Often known as "Colcrete" piling, which is a type of trade name. Usually replaced by diaphragm walling methods. Essentially typical bored piles, or down-the-hold bored piles, are constructed with a spacing such that each pile is virtually touching the next. These are constructed on a hit-and-miss basis. After a suitable length of these piles are in place (often 9 piles or so) a smaller drilling rig follows on behind placing the "colcrete" piles. A small diameter shaft, often 100 mm or so, is drilled on the external face of the pile wall close to the interection between the two main piles. This excavated pile is fitted with a grout tube and backfilled with gravel. The pile is then grouted and forms a seal between the adjacent piles. This type of pile wall can be constructed with either a standard reinforcement cage or a "H" pile. Info below achieved on project in Bermonsey, London - Sept 2010 1 rig, 600dia contig piles, 12-15m deep, 12No per day (average), 15No per day (max) Rule of thumb based on Hit 1, Miss 3 = 8.5l/m day per rig.

Grouting Operations Grouting Vertical Grout Curtain Application of grout curtain. A typical rate of 6.20 hrs/m run.
Hand Dug Caissons Principles Of Construction This type of "pile wall" is typical employed in areas where headroom or proximity to buildings restricts the use of large diameter bored pile drilling rigs, or where the wall is to be located very close to an existing structure. These are very time consuming and in allot of areas no-longer allowed as an acceptable safe construction method. Stringent air monitoring and safety isses are adhered to during the construction of the caisson. An electric chain block and hoist structure is maintained at the pile head for access and egress of both materials and operatives. Site Investigation / Advanced works Advanced grouting is often carried out around the group of caissons in order to reduce water inflow into the caisson area and provide adequate safety factor against base heave failer. Grouting of the area will also restrict ground settlement due to changes in the water table during caisson construction. A 75 mm diameter grout hole is drilled to 2 m belowthe specified toe of the caisson. On completion of drilling, a 40 mm inside diameter PVC, Tube-a-Manchette (T-A-M) grout tube will be installed to the bottom of the grout hole. The tube is usually perforated at 300 mm intervals with each perforation being covered by a tightly fitting rubber sleeve to act as one way valves. The grout hole is often backfilled with gravel and then pumped with grout to the specified pressures etc.. After each stage of grouting the T-A-M will be flushed with water to allow future grouting as necessary. The slightly conical excavation core is carried out by hand and a formwork erected and concrete placed in the void between the excavation and the internal formwork. Excavation down to the next level then begins. Excavation Of Caissons All excavation is carried out with air tools and shovels etc. Material is loaded into a 0.2 m3 drum skip. Hand excavation to a depth not exceeding 1 metre. Fix a suitably braced 3 segmented tapered shutter, fix reinformcement and pour concrete to fill all voids between the external face of the lining and the earth face. This operation is undertaken continously until the founding level is reached. Steel Reinforcement Reinformcement is placed either in prefabricated cages or directly erected in side the bores, depending on headroom and caisson access conditions. In some instances a steel "H" beam is installed in place of a reinforcement cage. Concreting Concrete is cast in place in one continuous operation using the tremmie pipe method, up to cutt-off level. The concrete is generally not vibrated.

Secant Piling Principles Of Construction • Often known as "Benoto" piling, which is a type of trade name. Usually replaced by diaphragm walling methods. • Essentially typical bored piles, or down-the hold type bored piles, are constructed with a spacing slightly smaller than the chosen diameter of the piles. Once a suitable length of piling has been completed, the "holes" are filled with a similar bored pile which intersects and "bites" into the two previously constructed piles. • Usuall these piles are strengthened with a steel "H" pile, rather than the typical reinforcement cages used in standard bored piling. As-Built Examples • Large diameter circular secant pile cofferdam. • Structure consisting of 1,200 mm diameter secant piles to a depth of 20 which then stepped into 900 mm contiguous piles for a further 20 m depth. Each pile was probed to 10 m depth in advance. A total of 255 number piles were constructed. • The "cofferdam" had a 1.4 m deep concrete base slab with a concrete lining to the walls. • An intermediate concrete roof slab was placed to form an underground box structure. • Overall construction time 12 weeks (Heathrow Express).

Escalator Installation Modular Design Escalators Packages The escalator trusses are usually delivered in 1.6 m cubes, which include the internal workings etc. Normally 3 to 4 sections go to make up a standard escalator (an 11 m rise), however sizes and lengths vary greatly. Delivery Implications The largest single element is the nose piece which is approximately 1.8 m wide, 3 m long and 2.5 m high. This section weight 1,500 kg. The other truss sections weight only 1,000 kg at most. The maximum weight of an entire escalator (10 m rise) is estimated at 15,000 kg. It is usual to being the escalators in from the top landing and lower the whole truss down into its final position. Power supply being 415 volt 3 phase hard wired, T&C may be done with temporary supplies. Typical Project Strategy Sequence /timing of works: • • • • • • •
16 wks = Develop concept design / submit for approval. 12 wks = Prepare preliminary design / submit for approval. 60 wks = Manufacture, test & site delivery, in conjunction with completion of final design. 4 wks = Initial delivery placing and connection of truss sections. 12-16 wks = Install escalators and commission. 12 wks = Test running of escalators. 12 wks = Trial running of escalators / System Operational.
Typical Escalator Installation Sequence Timing of single escalator: • • • • • • • • •
1 wks = Assemble sections and truss position, align, level. 6 wks = Escalator contractor "stop work" period, to allow ABWF contractor to complete surrounding finishes. 5 wks = Final escalator installation, "Phase B" decking installation and glazing etc. 0 wks = Escalator Power-On required. 2 wks = Test performance "Phase C" prior to escalator Test Running. 2 wks = Full load test "Phase D" of escalator. 1 wks = Final test "Phase E" 1 wks = EMSD Inspection of installation. 1 wks = "Phase F" inspection.

Fibre Cables There are 4 phases to laying fibre cables - The laying of the duct, the pulling of the fibre cable, the splicing/terminating of the cable and the testing of the cable. The production rate for the laying of the duct will be as any similar small diameter pipe and dependent on the location and linear distance. The cable pulling phase has less to do with the length of the pull and much more to do with the number of pulls required ie draw pit to draw pit distance is less important than the number of times the cable pulling operation is started and stopped. Production is therefore the number of pulls per day. The installers will generally attempt to install the cable from termination point to termination point in one day. Depending on the environment, an assumption of one pull a day is conservative and 2 a day being more optimistic. Crew sizes are small, 3/4 operatives. The termination is obviously a speciallist job and likely to be carried out by different small crew than the pulling of the cable. The duration is dependent on the number of fibres in the cable, but an assumption of one day per location and another day for testing at that location is reasonable.

Stone Cladding External Stone Walls Various stone finishes are available... Polished / Tooled = Highly reflective finish. The full colour and grain of the stone becomes visible. A poished fiish seals the pores and gives a good weather and chemical protection. Honed = Very smooth finish without reflections to show the full colour of the stone. Flamed = Produced by applying a high-temperature flame to the surface ofthe stone. This flame fractures the surface crystals, leaving a rough textured finish. Sequence of operations... Each wall stone is individually numberd to correspond to theshop drawings. The setting out line is established and metal brackets and subframe is installed in accordance with the initial setting out line. Prior to drilling a cover meter is employed to check the cover on the concrete reinforcement. Each stone is individually supported and restrained. Typical wall panel size 0.75 m2/stone. • • • • • • • • •

Petrochemical Oil & Gas Rates & Build Times:
Pipeline Construction Pipe welding is not that straight forward. You have a number of welding passes to take into consideration, then NDT and finally hydrotesting. I worked on a pipeline construction project in Iraq and used the following formulae to work out duration for the welding. The average welder can complete about 140 inches of weld per hour in ordinary 1/4 inch wall line pipe. Therefore, to find the output duration per day you would need to: Number of welds per hour is equal to = ((140/((diameter of pipe - in inches)*3.14))). This gives you an hourly rate of pipeline joints per hour. Times this by the number of hours in the shift to give the daily rate. You can work out how many sections in the run by dividing the run by pipeline length (typically 12m). Then divide this answer by the answer to the welds per hour. This will give you the outline duration for the welding. The welding runs normally follow each other so add half a day lag for each pass (1 day extra). Increase the overall duration by the estimated time to string the pipeline. NDT can happen while the welding is ongoing (obviously on different sections of the pipeline). Add a day overlap from the welding finish to complete NDT. Depending upon the length, include a day to fill the pipeline for Hydrostatic Testing, a day to test and a day to drain. Then you will need to add in a day for hook up. The welding duration will decrease if you have more than 1 team completing the task. We included an in country overhead factor which reduced productivity by 40% to allow for the heat (it was anything upto 60 degrees in the desert in summer), they did a lot of work before the sun came up etc. Overall, this rule of thumb worked very well. Obviously, you will be rounding up rather than rounding down. Additional... I am involved in a number of pipelines across India and when they deploy automatic welding they can cover 500m a day on 30inch pipe. Its a bit slower when you are going over a mountain range.

Hoists & Cranes Crane Grab Tender rates are often quoted as between 20 and 25 m3/hr. With adequate supervision and sufficient loose spoil material supplied to the crane drop area, these rates can easily be increased. Grabs mounted on crawler cranes, rates depend on... • • • • • •
Depth of the spoil to be removed Operative supervision - breaks etc Management and availibility of lorries Efficiency and utlisation of banksmen Transport of spoil to crane drop area Down time of machinery and staff
Clamshell Grab Mounted on a crawler crane... 2.0 m3 bucket (HK Cut & Cover Tunnels) • 33 m3/hr • 1.5 m3 per lift • 2.9 mins per lift 2.5 m3 bucket (HK Station Box) • 41 m3/hr • 2.0 m3 per lift • 3.1 mins per lift
Hydraulic Excavator • • • • •
Tractor with backactor, Massey Ferguson or JCB.3 has a 0.3 m3 bucket. Smaller 360 degree excavator has a 0.4 m3 bucket. JCB.6D, Liebherr 400, Hymak 580 or typical 360 degree machine has a 0.5 m3 bucket. 360 degree excavator machine has a 0.6 m3 bucket. Large 360 degree crawler backhoes have a 0.75 m3 bucket.
Rail Grab Machine Rail Mounted Hydraulic Grab Rate of 30 - 50 m3 of sand per hour (dependant upon depth), with 1.5 m3 made (2.0 m3 bucket) with each machine lift. Giving a required lift rate of 2.4 mins. A rate of 37 m3/hr (per rig) was achieved on HK Station box excavation. This was achieved with inadequate supervision and and long breaks etc. The standard lift time was 3 mins.

Floating Track Slab Pre-cast concrete blocks that support standard steel tracks. They are used to reduce noise and vibration as the pre-cast track slab blocks are placed on resin pads (4 no per unit), held in place by fixed side and end restraint blocks. • Side restraints, 0.8 m long, 12 no/day = 9.6 m/day • Resin pads, 10 no/day = 10.0 m/day • FST Units, 5 no/day = 10.0 m/day The above rates were achieved with a 6 man team, but could have been be speeded up by 200 300 % if a works train was available to hoist the units into place. The above was done with a "A" frame and chain hoist.

Cone Fracture Rock Breakage Penetrating Cone Fracture Rock Breakage. Tradename of "SunBurst" from Australia. State of the art, non-explosive chemical rock breakage technology for close proximity excavation applications in mining and civil engineering. Explosive system, cycle time of 6 mins, giving 0.33 m3 each explosion. A typical rate of 10 No cycles per hour, giving 3.3 m3/hr/rig. However, tests have shown differing results... Fresh granite of class 1 strength - One hole in the floor, yielding 0.15 m3 of rock. If more holes had been injected, a yield of 0.5 - 1.0 m3 would be expected. Moderately fresh igneous rock of class 2 strength - Three holes in a sloping trench, in adjacent locations, yielding 2.6 m3 of rock for each hole. Moderately weathered volcanic rock of class 3 strength - Two holes in the floor, in separate locations, yielding 1.2 1.5 m3 of rock for each hole.

Elevated Watercourse Modification of an existing 6 m high elevated canal. Normal canal is 12 m in width, to allow single passing on bridge/aqueduct structures, a 5.5 m minimum width is required. Normal depth of water is 1.3 m. Some 4 number "V" shaped piers on 1,200 mm bored piles, each 20m deep, supported a central span of 40 m with 17 m elevated "run on" section between the piers and ground abutments. Overall length 75 m and 5.5 m wide water course and 3.5 m footways on each side. Clay dams were installed at each end, canal was drained (fish removed !) with some 35,000 m3 of excavation removed. • Overall time period = 38 weeks • Construct new lock = 29 weeks By accessing any further pages of this website you agree to be bound by our Planning Planet T&C's Copyright © 2013 Planning Planet - ( Run by Volunteer Planners for Planners ) - Contact Us [email protected] Source URL: http://www.planningplanet.com/wiki/422384/rates-norms-durations Links: [1] http://www.pmlconstructionltd.co.uk/
