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

Challenges & Solutions:

Challenge 1:

The client wanted value optimization to be addressed thoroughly. 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 fabrication scripts and shared them with the client to meet the requirement of sheet metal CAM.

Challenge 2:

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

Solution 2:

As per 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 3:

Generating hanger drawings and the corresponding Bill of Materials (BOM) presented a challenge. It was difficult to obtain precise hanger sizes and rod diameters for the fabrication Clevis hanger, which was designed specifically for individual pipes.

Solution 3:

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:

• The contract drawings for domestic water piping did not include any valves. Pinnacle addressed this by adding the required valves and obtaining client approval during the final submission.
• Pinnacle implemented a rerouting strategy for the UG Sanitary piping to circumvent the presence of grade beams underground. In cases where rerouting was not feasible, we recommended the installation of sleeves around the beams.
• Due to the owner's construction preferences and requirements, the document underwent multiple markups and revisions. The Pinnacle BIM team devoted significant effort to incorporate these changes into the model for review and validation.
