Project snapshot

  • Project: King Salman Park, Riyadh, Saudi Arabia
  • Service: Multi-discipline BIM modelling and shop drawings, including structural shop drawings and rebar detailing
  • Team: 22 engineers
  • Duration: 14 months, April 2024 to June 2025, extended by variation order
  • Structural shop drawings reviewed: 973 in the main contractor's review log (954 approved, 19 returned)
  • First-pass approval: 98%

What the team delivered

The team worked across BIM modelling and shop drawings for the project. The structural package is the part with a clear audit trail: every structural shop drawing submitted went through the main contractor's review, and the review log records the outcome of each one.

Shop drawings are the documents a contractor builds from, so they are checked closely. A drawing that is returned has to be corrected and resubmitted, which costs time on site and in the design office. First-pass approval is a useful measure of this kind of work for that reason: it shows how often a drawing was right the first time it was reviewed.

The result in numbers

  • 954 structural shop drawings approved on review.
  • 19 structural shop drawings returned.
  • 98% first-pass approval (954 of 973 reviewed).
  • 22 engineers working as one team for 14 months.
  • An extension by variation order, which means the scope was widened after the original engagement.

The figures come from the main contractor's review log for the structural shop drawings. They describe the structural package only, not every drawing produced on the project.

How OEG sets up a team like this

The structure of this engagement is the way OEG builds dedicated BIM teams for other clients:

  • Named people. You receive named profiles, not a pool of anonymous resources, and you interview every candidate before they start.
  • Your standards. The team works in your templates and standards, in Revit, AutoCAD and Navisworks, from LOD 100 to 500.
  • Inside your environment. The team can work inside your own systems and VPN, so files do not need to leave your environment.
  • One rate. One monthly rate per person covers salary, employment costs, equipment and account management. There is no recruitment fee.
  • Protected work. An NDA is signed before you send the brief, and IP is assigned to you.

Confidentiality

This case study does not name the consultant or other parties on the project. The figures and dates are the ones OEG is able to share.
