General Contracting Company
Muscat, Oman, Middle East
Airport Infrastructure Construction
Set of IFC drawings and BIM models for architectural and structural Part
Clash-free MEP 3D Model, MEP Coordination Drawings
AutoCAD Revit Logo Autodesk NavisWorks Logo

Business Needs

The client needed a clash-free coordinated model in Revit and clash detection reports in Navisworks for a completely new airport project in Oman for the office buildings, passenger terminals, South Tier, North Tier etc.


  • Coordination and collaboration with different stakeholders across disciplines (architectural, structural), geographies and time zones.
  • Syncing MEP scheduling of models with randomized scheduling of other disciplines.
  • Adjusting resources to align with fluctuating/shifting schedules of multiple activities.
  • Too many clashes in the 2D drafts which had to be negotiated when converting to 3D MEP models.

Our Solutions & Approach

Create clash free 3D MEP models in Revit with LOD 400 along with clash detection reports.

Share Your Thoughts
  • Assessed IFC drawings shared by the client at DD level to understand possibilities of clashes and pre-empt them.
  • Imported 2D drawings to Revit to create clash free 3D MEP models in Revit with LOD 400. Then transferred MEP models to Navisworks to detect clashes and generate clash detection reports.
  • Accommodated fluctuating resource and scheduling requirements at different stages of the project ranging from 10 to 25 project members with stringent QC channels established based on lesser RFI’s to mitigate delays.
  • Accurate material and resource planning with reduced field conflicts based on coordinated drawings delivered to client within stipulated time.

Business Impact

Hitech CADD Services’s BIM/VDC tools & collaborative project delivery approach resulted in savings of $7M in 6 months. Project completion resulted in an operational terminal with 100% of MEP systems installed with zero change orders due to diminished filed conflicts.
