COMMISSIONING MANAGEMENT

Our focus as Commissioning Managers is to ensure buildingservices are commissioned in a proper and timely manner. Our expertise allows us to strategically set clear and systematicsteps to ensure a properly commissioned building.
Our Commissioning Management model provides an overview ofarrangements, which follow CIBSE-Code M guidelines and BSRIAapplication guides to ensure building services systems arecommissioned to meet objectives set out in Building Regulationssuch as LEED, Estidama and DGBR etc.

TESTING, ADJUSTING AND BALANCING

Testing and Balancing plays a vital role in commissioning process of HVAC system. The proper commissioning of Air/Water distribution system is crucial to ensure the correct operation of the building which it serves, and any of the associated building services plant. It’s important that the system is balanced to deliver the design condition and optimum power consumption, which is possible only through Testing and balancing.

The commissioning team involves step by step procedure In various activities of Installation and execution. This Involvement ensures the correct installation and achievement of the system Performance nal. the design tent.

Installation Checks

• Ensuring system Installation as per approved drawing and manufacturer recommendation
• Installation check on the equipment, Control device, regulating devices i.e., (Damper in duct network,valves in piping network)
• Preparing commissioning snag and addressing to construction team to carry out the proper commissioning.

Pre Commissioning Checks / Initial Set

• The Commissioning team will be familiarized with project specific method statement as well as shop and schematic drawing prior to execute the pre commissioning check activities. The team will carry out pre checks and set the equipment to work and ready for commissioning.

System Commissioning

• Verifying Approved equipment as per manufacturer recommendation and consultant requirement, the team will proceed to test & record the readings for following units with help of the manufacturer technical data and their representative to achieve the design intent.

ELECTRICAL TESTING & COMMISSIONING

We offers a full package for electrical systems testing after installation is complete to verify proper functioning of the system and to ensure that the performance meets the design intent & IEE regulation.

RETRO-COMMISSIONING

Retro-commissioning usually results in improved system and equipment operation that goes beyond routine operation and maintenance. It looks at control strategies, sequences of operation, interaction of mechanical HVAC, lighting, building enclosure, and how related systems affect each other. It provides a comprehensive analysis of a building’s energy performance. Recommendations are provided on reducing energy consumption and demand charges. Improved equipment performance leads to longer life spans, more reliability, fewer repairs, and lower energy costs to operate. Indoor environmental conditions include improved room temperature, relative humidity and building pressure control.

DUCK LEAK TESTING

Leakage Testing & Pressure Testing for HVAC Systems & Ductwork

We offer independent ductwork pressure testing service in accordance with BESA DW143. We test that ductwork leakage is within the allowable rates stated in BESA DW144.
Our teamsare fully trained in the equipment usage, testing methods and calculations.
HVAC leakage testing is a crucial aspect of testing and commissioning for new buildings as well as refurbishment works.

DW143 Leakage Testing

BESA DW143 outlines the allowable leakage rates for low, medium and high-class ductwork systems. Reeftech high sensitivity ductwork pressure testing equipment allows us to test all ductwork classes from A to D. Testing is only mandatory for ductwork classes B to D but with increased attention on building’s energy efficiencies testing of class A system may also be specified. Kitchen Extract LEV systems installed in accordance with DW172 are class A installation unless otherwise stated.

Pressure Testing Procedure

Drawings will be requested prior to works commencing in order to accurately quote for works. Tests are carried out by dividing the ductwork into manageable test sections, test sections are blocked off using reusable blocking materials such as high-quality foams. Test sections are placed under pressure, specified in DW143, results are then calculated and witnessed by the client for sign-off. All documentation is sent out electronically to all parties on the day, this includes the test calculations and equipment calibration certificates.

Resolving HVAC Leakage Issues

It will be the responsibility of the ductwork contractor to rectify ductwork leakage if it exceeds allowable limits. Traditional methods for reducing ductwork leakage are to apply additional clamps, fixings and mastic to increase airtightness. This process is time-consuming but it can make a small improvement to the overall airtightness of a system, however many areas of the system may be difficult to reach above ceilings, behind walls and other building services. In cases where access is difficult or dramatic improvement to airtightness is required then a specialist solution is needed,

QA/QC WORKS

As QA/QC Engineers, we offer activities to QA/QC works against project requirement at practical completion. But not limited to

Production of Project Quality Plan
Review the Material Technical Data Sheet
Preparation of Method Statement

ENERGY AUDIT

Performance contracting is a method of funding in which energy savings from utility expense reductions are used to pay for projects over the course of several years. Utility savings are realized through the implementation of various energy conservation measures (ECMs) that may include: high efficiency lighting retrofit, computer controlled energy management, and the replacement and redesign of older, inefficient heating ventilating and air conditioning (HVAC) equipment and systems, among others.

DOCUMENTATION MANAGEMENT (O&M AND TRAINING MANUALS)

We produce quality operating and maintenance manuals to suit your own specific project requirement for both Mechanical and Electrical installations, but not limited to.
