Heating, Ventilation and Air-conditioning

Objective

Preparation of Digital HVAC and Piping layouts for multi-storey buildings with reference to supplied scanned images.

Description:

HVAC (Heating, Ventilation and Air-conditioningsystems use ventilation air ducts installed throughout a building that supply conditioned air to a room through rectangular or round outlet vents, called "diffusers"; and ducts that remove air from return-air "grilles". We create the CAD plans to show the ducting layouts for air supply and air return.

  • AABSyS created the customized line types as per client’s requirement to import the data into other CAD softwares.
  • aster images were fitted on top of the existing floor plans.
  • Constructed the air-ducts and pipes as per dimensions provided on the scanned images.
  • Standard line-types were used to draw the HVAC and Pipelines.
  • Congruencies between vertical pipes running through different floors were taken care of.
  • Blocks were created and used to maintain uniformity between plans.
  • About 250 layers, 60 line types, different colors are used in the drawings.
  • Attributes were tagged to different pipes separately.
  • 3 rounds of QC were performed to maintain the quality. 1) QC using the AutoLISP programs to find out the errors in layers and line types, 2) Matching the hardcopies of vector and scan. 3) Screen QC.
  • Merged the different drawings to produce a homogenized single floor plan.
  • Delivery was done in DWG.
