1. Objective

To supply, install, test, and commission 165 BTU meters and One Bulk meter in main riser line in accordance with relevant standards and regulatory requirements. The objective is to ensure accurate monitoring of chilled water energy consumption in individual units and/or common areas for billing and operational efficiency.

2. Scope of Work

2.1 Supply and Delivery

• Supply of 165 BTU meters (preferably ultrasonic type with MID certification).
• Supply of all associated components including:
• In-line flow meters
• Matched temperature sensors (supply and return)
• Data communication modules (e.g., M-Bus/Modbus/BACnet)
• Isolation valves (as required)
• Cabling, conduits, junction boxes, mounting hardware, and with PC
• Transportation and delivery of all materials to the site.

2.2 Site Survey and Planning

• Conduct a detailed site inspection and technical assessment of all installation locations.
• Coordinate with the facility management team and confirm unit access for installation.
• Verify pipe sizes, flow direction, and installation feasibility at each unit.

2.3 Installation

• Mechanical installation of BTU meters, including:
• Proper positioning of temperature sensors on supply and return lines.
• Mechanical pipe cutting and reconnection (if required).
• Proper alignment, sealing, and insulation of all fittings.
• Electrical installation and integration of communication modules.
• Labelling of all meters and sensors with unit numbers and unique IDs.

2.4 Cabling and Communication

• Installation of data cabling from each BTU meter to a central data collection point or network gateway.
• Configuration of communication interfaces (M-Bus/Modbus etc.).
• Connection to Building Management System (BMS) or third-party billing platform (if applicable).

2.5 Testing and Commissioning

• Functional testing of each meter.
• Verification of accurate flow and temperature readings.
• Leak testing of all mechanical joints.
• System commissioning with data validation and calibration records.
• Preparation of test & commissioning reports for each meter.

2.6 Documentation and Training

• Submission of:
• Manufacturer's technical datasheets and calibration certificates.
• As-built drawings with meter locations.
• Serial number registry mapped to unit numbers.
• Installation checklist and final commissioning report.
• On-site training for maintenance and operations staff covering:
• Reading and interpreting BTU meters
• Troubleshooting common issues
• Routine maintenance guidance

3. Warranty and Certificates

• All BTU meters and accessories must come with a minimum warranty of 24 months from the date of commissioning.
• Warranty should cover manufacturing defects, calibration stability, and functional reliability.
• Contractor must provide:
• Warranty certificates from the manufacturer.
• Calibration certificates issued by certified laboratories.
• Certificate of compliance with MID (Measuring Instruments Directive) standards.
• Certificate of installation and commissioning endorsed by a licensed engineer.4. Insurance Requirements

• Contractor shall provide proof of:
• Public liability insurance covering any damage to property or injury to individuals during execution of works.
• Workmen’s compensation insurance for all personnel engaged in the installation.
• Professional indemnity insurance covering design and installation errors (if applicable).
• Copies of valid insurance certificates must be submitted prior to commencement of work.5. Project Duration

• Total project duration: [Insert estimated duration, e.g., 30–45 working days] from the date of site readiness.
• Detailed timeline to be submitted with the contractor’s proposal, including mobilization, installation phases, testing, and handover.

• Any civil works beyond BTU meter installation (e.g., false ceiling modifications, wall chasing, or repainting).
• Supply of BMS/billing software (unless specified separately).
• Power supply provisions beyond standard connectivity points.

7. Compliance and Safety

• All work shall be carried out in accordance with local authority regulations (e.g., DEWA, RSB, Dubai Municipality, etc.).
• All personnel must comply with the building’s safety rules and procedures.
• Site access must be coordinated with building management.
