Criminal Evidence Processing Complex

Scope of Work:

• Plumbing & Mechanical 3D model, Co-ordination
• Shop Drawing/2D Drawing
• Penetration drawings with Trimble files
• Hanger drawings, Pipe cut length, Piping spool drawings
• CAM drawings, Mech piping riser drawings

Challenges & Solutions:

Challenge 1:

The client wanted value optimization to be addressed through the course of execution. This added to the complexities in terms of carrying out the project and increased the chances of production lags and process halts.

Solution 1:

We raised RFIs and communicated with the client through weekly review meetings. This included taking the client's suggestion before dealing with any coordination issue such as rerouting of the duct. We also created some fabrication scripts and shared them with the client to meet the requirement of sheet metal CAM.

Challenge 2:

RMS fabrication was one of the challenges

Solution 2:

To support RMS fabrication, team Pinnacle prepared the sheet metal CAM drawing. It helped in overcoming fabrication challenges and executing construction in a timely manner.

Challenge 3:

The material to be used needed to be planned as per the cost constraints.

Solution 3:

In accordance with the project specifications, we made adjustments to the pipe material and length in order to minimize the number of short pieces and thereby reduce costs. Additionally, we prepared a sample drawing illustrating the cutting lengths of the piping based on the fabrication package.

Challenge 4:

The creation of hanger drawings and the corresponding Bill of Materials (BOM) posed a challenge during this project. Since the fabrication Clevis hanger was specifically designed for individual pipes, obtaining accurate hanger sizes and rod diameters from the Revit schedule for the fabrication object proved to be difficult.

Solution 4:

We raised RFIs and communicated with the client through weekly review meetings. We took the client's suggestion before dealing with any coordination issues such as rerouting pipe and duct. In this process, we utilized a dynamo script to get the fabrication object (Hanger) size and rod diameter. Also, we created some fabrication scripts and shared them with the client to meet the requirement of sheet metal CAM.

Pinnacle’s Value Addition:

• No valves were shown in the contract drawings for domestic water piping. Pinnacle added the valves as per the requirement and verified from the client during the final submission.
• Pinnacle rerouted the UG Sanitary piping to avoid grade beams underground and suggested sleeving the beams when rerouting was not possible.
• There were various markups and revisions in the document due to the owner’s construction preferences and requirements. The Pinnacle BIM team worked diligently to adhere to the changes in the model for review and validation.
