Introduction

1.1

Purpose

1.1.1

ofthis The purpose of this document is to specify the Functional, Performance and Interface requirements applicable to the provision of Mechanical, Electrical and Public Health (MEP) Services for Stage 2 & 3 of Etihad Rail project. The Contractor shall design and install all MEP services necessary for operating and maintaining the project facilities which shall include, but not limited to the following:a) Passenger stations and associated facilities such as car parks, pedestrian bridges, access ways and the like; b) Etihad Rail freight facilities; 0&M facilities including depots, marshalling yards, yellow plant facilities, signalling and c) O&M communication facilities; d) Regional offices; e) Wayside buildings including sub-stations, signalling and communication structures; and (ortunnel f) Tunnel service buildings (or tunnel portal buildings).

1.1.2

1.2

Standards Standards

1.2.1

The designs are to be produced to comply with UAE Local Codes and with International and European Standards where applicable (and where UAE local codes do not conflict). The Electrical Building Services Design shall be based on applicable standards, codes and requirements of the relevant local electricity supply authorities having jurisdiction (ADWEA/ADDC, DEWA and AADC as applicable) and relevant Standards referenced below. All codes and standards used in each instance shall be the latest edition or issue, and the most recent revision, amendment or supplement at the date of tender invitation. The Contractor shall be responsible for obtaining all current copies of the standards and regulations either directly from the local authority or from their respective websites as applicable. In the event a condition is found that is not covered by these codes, regulations and criteria, the Contractor shall refer the matter to the Engineer. Where the requirements of more than one code or standard are applicable, or where there is a conflict between different standards; the more stringent requirements shall prevail. The MEP installations and related works shall additionally incorporate the requirements of the relevant Authorities having jurisdiction including but not limited to: havingjurisdiction a) Relevant prevailing standards, including but not limited to the Abu Dhabi and/or Dubai Municipality Standard Specifications, and any other applicable Stakeholder Standards and Requirements. 1303-SOZ-EWA-RP-0001.
