Procurement Routes for Public Sector Building Works

Why procurement route matters

The procurement route for public sector building works directly affects cost, quality, programme, governance compliance and the client's ability to demonstrate accountability. Choosing the right approach depends on the nature of the works, the value, the governance framework and the level of competition needed.

When procurement decisions need to be made

Procurement planning should start early, before specification is finalised. Key decision points include after condition assessment identifies works requiring external contractors, before Section 20 consultation for leasehold stock, where governance thresholds require formal tendering, where framework agreements may offer a structured route, and where previous procurement has produced unsatisfactory outcomes.

What the main procurement routes look like

Open competitive tendering is suitable for larger works where maximum competition is needed. Selective tendering is suitable where a shortlist of capable contractors is identified before tender. Framework agreements are suitable where pre-approved contractors are available and governance permits. Single-source appointment is suitable only in limited circumstances with clear justification.

Each route has implications for programme, cost certainty, governance compliance and the quality of the contractor pool.

Who normally leads procurement

Procurement leads, estates teams, capital projects managers and external consultants acting in advisory or contract administration roles. Public sector procurement often involves additional layers of governance, approval and documentation compared to private sector instructions.

Common mistakes to avoid

Starting procurement before scope and specification are properly defined. Choosing a procurement route based on speed rather than value and governance compliance. Not maintaining an audit trail of evaluation and decision-making. Failing to evaluate tenders against both price and quality criteria. Not appointing independent contract administration for delivery oversight.
