The commissioning phase of any project is often key to the sustainable, comfort and environmental, performance of a building, vis-à-vis the system design.

It is well known that over the life of the equipment, just the energy cost of operating and maintaining present building HVAC services are 5 to 10 times the total equipment cost.  Hence the importance of focused design and commissioning portfolios cannot be overstressed.

 Reef Tech Services L.L.C. acknowledges it’s responsibilities in this regard and has set standards which will easily maintain the high standards expected by the building services industry in the UAE. 

Our aims are primarily to meet the ever growing commercial demand for practical experience and professional expertise within this sector.

Reef Tech Services  L.L.C. has been formed to provide this specialized, quick, efficient, reliable, flexible and cost- effective technical service to the Building Services Contracting and Consultancy fields. We also offer a wide range of other services including, Validation & Site Surveys, Energy Surveys, Sound Level Measurement, and Technical Documentation.

We achieve this by providing a pro – active service with open channels of communication with our clients.

In order to satisfy these demands we are led by a dedicated engineering team with a combined experience of 65 years in installation, commissioning, operation and maintenance of building HVAC services and equipment.

Time and again during our validation and site surveys, especially, in refurbishment and renovation projects, we have been instrumental in assisting the design team and contractor to correctly select and set equipment, according to site conditions, in order to provide optimum performance for the client.

All of our staff are skilled, with industry accreditation as their foundation. We will soon hold Membership status with the CSA (Commissioning Specialists Association.UK) and NEBB (National Environmental Balancing Bureau.USA) as the principal bodies ensuring high standards within this industry, worldwide.  Our activities are also guided by the recognized standards and codes of practice as laid down by BSRIA and CIBSE (UK) and AACB (USA)

The company focus and purpose is to fortify it’s ability to respond quickly and efficiently to fast track projects, and to the increasingly sophisticated plant, equipment and design schemes typically being provided for the innovative and multicultural Building projects in this area.

From order placement through to practical demonstration of system performance, we are committed to provide the highest degree of professional response. Our method statements are carefully prepared to provide a detailed explanation of our procedures and the requirements upon which they are dependant.

Our planning and management routines are prepared to similarly meticulous standards, and where necessary detailed charts and labour histograms supplement our method statement and programs.
