Client Profile.
The client is a leading architectural firm specializing in planning and designing of signature tech buildings across the USA.
Business Need.
As the first phase of the project, HitechDigital had delivered a detail-rich 3D BIM model in Revit for data center building design development and construction.
Once the design was completed, the client needed detailed construction drawings to be submitted to concerned authorities for necessary approval. They commissioned HitechDigital once again to deliver:
- Detailed GFC drawings for onsite decision making
- Fabrication and installation drawings for various structural elements and MEP components as per AIA standards
HitechDigital was also assigned the task of ensuring that the designs were clash-free at a very micro level.
Challenges.
Design inputs received from the client originated from different stakeholders so getting all of them on same page for design finalization was a critical task. Additionally, input files also posed challenges such as:
- Managing and raising multiple RFIs to get missing information on time
- Resolving interdisciplinary clashes in internal design elements when part-sections and enlarged sections were developed
- Ensuring uniformity in standards and templates across all input drawings
Solution.
GFC drawings across all disciplines extracted from coordinated Revit 3D BIM model were shared with the client using BIM 360 cloud platform. This enhanced real-time information sharing and site efficiencies, quicker approvals, and eased onsite resource management.
Approach.
A project team of Revit engineers was put together to develop coordinated BIM model from individual Architectural, Structural and MEPF layouts shared by the client.
- The project team imported the individual files in Revit platform to develop a fully-coordinated model
- Next step was to identify and resolve any design clashes to get clarifications and approvals from the client
- This fully coordinated BIM model served as a base to extract GFC drawings and construction sheets
- The project team formulated sheet templates and formats for GFC sheets as per the client’s needs for sharing all information through a single file
- AIA BIM norms were selected to create construction sheets and drawings to show floor plans, plinths, duct location and wiring, electrical outlets, etc.
- IFC drawings, sections, plans, elevations, and approval drawings were extracted from the approved models to share seamless information across teams
- Fabrication and installation drawings for columns, pillars, HVAC ductwork etc. were also developed
- Any clashes that were found in internal elements were highlighted and sent back to BIM modeling team for resolution
- Final approval drawings were shared with the chief project architect at client’s end to sign off and then released for construction
