Design & Delivery Approach
Ingplan assumes full design responsibility for all wet services works. Coordinated drawings are produced in Autodesk Revit (BIM) and AutoCAD, enabling full coordination with structural, architectural, and other engineering disciplines. Subcontractors install directly from Ingplan’s approved drawings — no contractor re-drawing is permitted.
An experienced commissioning engineer verifies, checks, and tests all installations prior to practical completion and formal acceptance. During the 12-month defects liability period, performance is monitored via service reports submitted by the subcontractor.
