This case study is focused on Importance of Effective Communication and information exchange from Base build to End user, From End user to Design consultants during Project handover and design phase of the project at the right time based on the project deliverable timeline with respect to the level of development of the model in each design phase.
This case study is based on a digital design renovation project.
Location of Project: Bangalore, India.
Construction Project Delivery Method: Design-Bid-Build
Inputs Received from End User:
- Handoff package-Design Intent in PDF format, Existing condition scanned Revit model, Scope Matrix between Landlord vs End User.
- Package B-Design intent Specs.
Clear Scope responsibilities to be listed out between Base build vs End user vs Design Consultants.
This will make the designer to make the building design more effective as the information received from the Base Build and End user can be incorporated at the same time which in turn reduces the redesigning of Services, Change orders and time.
Key Issues: Due to lack of information shared from the end user at the initial stage of the project handover and in the design phase of the project major building services needed to be redesigned which in turn affected the additional time and cost to the end user and consultant.
Issue No.1: Fresh air and Exhaust ducting cut outs
Type of Air conditioning system selected: VRV/VRF with fresh air ducting.
Concerns: Base build team denied the permission to make cut outs in the beams which is available throughout the periphery of the building.
Designer planned to have cut outs at multiple locations in each floor for fresh air and exhaust (pantry exhaust) inlets and designed the services to required level of detail/development.
The base build as built drawing did not capture the availability of beams throughout the periphery of the building as well as no prior information was shared from base builder to end user to design consultant.
At the tendering stage end users have informed design consultants for rerouting of the services as the base builder has denied giving permission to make the required cut outs.
Even if the services require the cut outs, then it had to be offset near the periphery wall which leads to low services heights which in turn the fresh air ducting, Pantry exhaust ducting needed to be redesigned in all floors.
