1. BACKGROUND / RATIONALE
UNICEF office in Delhi is currently undergoing an energy efficient retrofit of the existing HVAC system in the building, with a goal to significantly boost the energy efficiency and environmental performance. This modernization effort is geared towards meeting stringent energy conservation targets and supporting the office's journey towards carbon neutrality. This retrofit encompasses conducting civil and electrical works related to implementation of the chiller plant, with minimal impact on daily operations.
To complete the retrofit within the fixed timelines, UNICEF India has developed specifications for civil and electrical works for this project. The TOR aims to identify a suitable service provider for supply, civil and electrical works, testing, and commissioning of civil and electrical works related to the Chiller Plantroom to the installation site in the building.
2. PURPOSE OF ASSIGNMENT
The main purpose of the assignment is to conduct civil and electrical works related to implementation of energy efficient chiller plantroom in the UNICEF India office building in New Delhi.
3. OBJECTIVE/S
The primary objective is to conduct civil and electrical works for the chiller plantroom implementation, ensuring it meets operational requirements and industry standards. The other goals under this assignment include:
• Dismantling: Safely relocate and dismantle civil and electrical components in the existing HVAC equipment (as per BOQ), ensuring the proper relocation of components to the ground floor and the removal of electrical panels.
• Civil Works: Execute comprehensive civil tasks, including setting up temporary partitions, demolishing existing structures, constructing new walls and lintels, installing waterproofing layers, laying new floor tiles, and installing fire-resistant doors, followed by finishing touches like painting and anti-termite treatment.
. Electrical Works: Install new power cables and grounding strips, integrate new equipment with electrical panels, and set up and connect cable trays and terminations to ensure a fully operational electrical system.
4. MAJOR TASKS TO BE ACCOMPLISHED
