MONITORING PROGRESS
For each project detailed activity bar chart is prepared. Based on site priorities, work flow sequence, time frame is provided for each work. Remedial measures are taken to control items behind schedule. Critical hold points are identified right in the beginning particularly in areas where interaction with order services are involved.
 
QUALITY CHECK LIST
We have our internal quality CHECK LISTS for various trades like ducting, piping, equipment installation etc. The site team follow these check list along with the approved drawings to inspect the work done.
METHOD STATEMENT- FOR HVAC WORK
 
DESIGN VALIDATION
Study of Customer need, design intent and application, system requirement & technical specifications
Visit to site. Collecting design inputs and drawings like architectural plans, reflecting ceiling plans, structural drawings and drawing related to utility areas
Calculations of cooling loads and air flow requirements for each control zone. Psychrometric analysis for critical areas, calculation of reheat figure, selections of apparatus dew points and finalizing air treatment process
Verification of systems pumping head, fan static pressure requirement, electrical load, water and air filtration need
Based on above, selection of equipments of desired rating as per technical specifications
Coordination with Architects and other utilities and preparation of shop and layout drawings
Preparation of air and water flow schematics, with necessary valves, strainers and control valves details and instrumentation input
Providing inputs for utilities / work to be provided by others out side battery limits
Obtaining consultants / architects approval and release of drawings for site work
Generation of material request as per approval and release if drawing for site work
