1. Project Overview

This project involves the full replacement of two existing Carrier 30GX-267-AO353 - NEE Air Cooled Chillers  with new, energy-efficient models. The work includes assessment, equipment supply, decommissioning, installation, testing, and commissioning. All activities will be carried out on a turnkey basis with no variations or extras to be entertained post-contract award.


2. Site Survey and Assessment

  • Conduct a comprehensive site survey to assess the current condition of the existing chillers and surrounding MEP infrastructure.

  • Evaluate the cooling load requirements based on current and future needs.

  • Assess power supply availability, piping configurations, and space constraints.

  • Recommend best-fit replacement model(s) with improved efficiency, capacity, and compliance with current DEWA and Green Building requirements.

Deliverables:

  • Detailed site survey report with chiller selection justification

  • Load calculation and technical comparison

  • Risk and logistics assessment for removal and replacement


3. Equipment Supply
