Why an Official Plan Holders List is Important
For public municipalities and project consultants, ensuring a fair, competitive, and efficient bidding process is essential. One of the simplest — yet most critical — tools to support this is maintaining an official plan holders list.
What Is an Official Plan Holders List?
An official plan holders list is a record of all contractors, subcontractors, suppliers, and consultants who have obtained the official project plans and documents from a designated source.
In short:
➡ The bid documents clearly state which agency or location bidders must contact to be added to the plan holders list.
➡ Those on the list are notified of any project changes, addenda, or updates.
This ensures that everyone knows where to get the official, most up-to-date information for a project — eliminating confusion and miscommunication.
Why Does This Matter?
Bidding on public works projects takes significant time, effort, and resources. Without an official plan holders list, several problems can arise:
-
Lack of coordination — Contractors, suppliers, and subcontractors may not know who is bidding as a prime or sub, leading to missed opportunities for collaboration.
-
Wasted time and effort — Bids can become fragmented, redundant, or incomplete, wasting valuable time for both bidders and the municipality.
-
Higher costs — Inefficiencies and uncertainty can discourage participation or lead to inflated bid prices.
-
Reduced transparency — Without an official source of truth, it’s harder to ensure that the process is fair and competitive.
The Benefits of an Official Plan Holders List
By maintaining and sharing an official plan holders list, municipalities and consultants can:
✅ Promote collaboration between contractors, subcontractors, and suppliers
✅ Encourage more complete, competitive bids
✅ Save time and reduce unnecessary costs for all parties
✅ Support the integrity and transparency of the public bidding process
Final Thoughts
An official plan holders list is a small administrative step that delivers big value. It ensures that everyone — from the owner to the bidders — starts from the same set of information, creating a smoother, fairer, and more efficient project delivery process.
