Situation: Pangbourne STP Flow Compliance Project, United Kingdom

In 2023, while working as a BIM Manager for COWI India, I contributed to the Pangbourne STP Flow Compliance and Chipping Norton STP Flow Compliance projects for Thames Water, with Tilbury Douglas as the client in the United Kingdom. I was responsible for developing BIM models and General Arrangement Drawings for underground utilities, including pipe supports, valves, and accessories.

The project was in its preliminary stages, with many design details unfinalized, particularly regarding the selection of suitable valve and pipe variants.

Task: Ensuring Correct Selection of Equipment Variants

My task was to validate and select appropriate equipment variants, such as Gate Valves,  Non-Return Valves, Ductile Iron Pipes, and HDPE Pipes, that were technically suitable and procurable in the UK market. Incorrect product selection could affect the cut length of Ductile Iron pipes, leading to rework and additional costs.

Actions:

Reviewing Product Options and Raising Queries

I reviewed product catalogs from proposed manufacturers to identify appropriate variants and compiled a list of preferred equipment for approval by the engineers. I then contacted vendors to verify the availability of these variants in the UK market and sought alternative options where required.

Evaluating Vendor Feedback and Updating Design

Upon receiving vendor responses confirming or suggesting alternative products, I forwarded the information to the engineers for approval. I updated the BIM models in Revit with the selected variants and added a parameter to document the model numbers, ensuring traceability for future reference.

Addressing Unspecified Sizes

In cases where exact sizes were not specified, I added a “Cut to Suit” note in the Bill of Materials to account for variations during fabrication.

Results: Validated Design, Ensured Traceability, and Avoided Risks

By validating product variants and ensuring their compatibility, I prevented procurement delays, costly rework, and potential misalignment issues. Accurate modeling reduced the risk of errors, while maintaining a traceable record of approved variants in Revit enabled effective tracking and minimized future discrepancies. This approach safeguarded project timelines, preserved structural integrity, and avoided costly modifications.

By identifying and addressing challenges early, I applied scientific and engineering principles to analyze problems, select appropriate solutions, and validate the correct equipment variants. This proactive approach ensured smooth project progression, preventing delays, technical inconsistencies, and unnecessary costs.
