When does the council ask for one?
Requirements depend on the authority, site and proposal. Camden's 2025 validation list identifies Construction Management Plans for major development and other relevant schemes. Its basement guidance explains why constrained sites and excavation close to neighbours can need detailed management arrangements. Epping Forest's 2026 list also links construction management information to basement impacts where appropriate. [3] [1] [4]
Check whether a draft is needed with the application and what must be approved before work starts. The required document and approval mechanism should be taken from the actual application requirements, decision and any planning obligation, not assumed from another project.
What should it contain?
Camden's basement guidance identifies phasing, site management, construction traffic and parking, noise, vibration, dust, waste, stability and movement monitoring. It also addresses ongoing communication with affected neighbours where the scale and duration of the work justify it. [1]
For the logistics part, ask the project team to explain how the proposed site will actually be supplied and cleared. Request a site layout that identifies access and the operational arrangements being assumed. Check that the document accounts for the site's constraints rather than simply stating that deliveries will be managed considerately.
A useful review meeting should establish who will implement each measure and what happens when circumstances change. Assign responsibility for keeping the plan aligned with the construction programme and specialist recommendations.
Who prepares it?
The contractor needs to contribute to the practical arrangements, with input from the designer and relevant transport, environmental or structural specialists. A planning-stage document prepared before a contractor is selected should make its assumptions explicit and identify what needs to be developed later.
Camden's guidance expects the plan to address site-specific impacts and neighbouring activity. The document should therefore reflect the chosen construction approach and the actual setting, rather than be an unedited company template. [1]
How is the construction phase plan different?
Under CDM 2015, HSE requires the principal contractor on a project involving more than one contractor to prepare a written construction phase plan before that phase begins, implement it and keep it under review. That document concerns management of health and safety during construction. A council's planning-management document does not replace those responsibilities. [2]
Information may overlap, but the purpose and responsibility for each document should remain clear. Use coordinated documents rather than treating one title as evidence that every requirement has been met.
Avoid universal working-hour assumptions
Camden's guidance explains that hours within a Construction Management Plan should reflect the site and work, with possible tighter arrangements. Do not copy another borough's hours as if they were a national entitlement. Check the permission, agreed plan and relevant local requirements. [1]
Before mobilisation, brief the construction team on the agreed commitments and keep the current version available. Where a proposed change affects those commitments, resolve the necessary review or approval before treating it as acceptable.
