The client is a leading architectural firm specializing in planning and designing signature tech buildings across the USA.
Business needs.
The firm was working on design development for a data center building. This needed accounting for and coordinating layouts across disciplines including architecture, MEPF and structure. Hence, they approached HitechDigital to:
Develop a clash free coordinated BIM model
Generate accurate Bill of Quantity (BOQ) reports to facilitate seamless planning
Project Samples.
Architectural BIM Model
Structural BIM Model
MEP BIM Model
Coordinated BIM Model
Challenges.
The project threw up challenges related to establishing collaboration across stakeholders and disciplines. Addressing problems in design inputs received as PDF files was also a major issue. Some input file issues were:
Inconsistent design symbols and quality of drawings led to ambiguity in design communication
Missing design details in drawings called for a lot of guesswork
Several markups and red lines in drawings posed difficulties in reading design instructions
Constantly changing concept design inputs resulted in significant modeling iterations Â
Solution.
A clash-free coordinated 3D BIM model in Autodesk Revit was developed, using design inputs from architectural, structural, and MEPF disciplines. BOQ reports were fetched for calculating accurate material and quantity estimates. Clash reports eliminated potential design clashes early during the development stage.
The solution shared over BIM 360 enabled reduction in construction waste, ease of resource planning and management of material storage.
Approach.
The project team received PDF files for architectural, structural, and MEPF disciplines to create a coordinated 3D BIM model in Revit. An expert team of BIM engineers resolved consistencies in design inputs and ensured necessary standardization.
First structural model was developed with all basic levels and using it architectural model and MEPF model with lighting, plumbing fixtures, HVAC ducts, wiring, fire protection systems arrangement, etc. were laid out and buffer spaces were considered
RFIs were raised to fill in the design interpretation gaps in input files
Once the missing information was received, all drawings were coordinated into a single clash-free 3D BIM model using Autodesk Revit
Every design element was checked for hard and soft clashes with each other and any that were found were resolved
The finalized Good for Construction[GFC] BIM model and extracted drawings were sent to the client for approval
Once approved, a detailed report on BOQ was generated to calculate material quantity and estimates
Construction schedules were also generated to mitigate conflicts and manage material storage on siteÂ
Final GFC model, construction documents and drawings, and reports were checked against quality benchmarks and shared with the client using BIM 360 cloud platform
