What Goes in a CLP

The TfL and CLOCS guidance lists seven: introduction; context, considerations and challenges; construction programme and methodology; vehicle routing and site access; strategies to reduce impacts; estimated vehicle movements; and implementing, monitoring and updating. Following that structure makes a submission easy to review, which is itself an advantage.

Site context, and local access including highways, public transport, cycling and walking provision, along with the community considerations that affect the assessed level of impact. This is the section that justifies the level of the plan, so a thin version undermines everything after it.

For buildings the guidance lists site setup and demolition; basement excavation and piling; sub-structure; super-structure; services and systems installation; and fit-out, testing and commissioning. It notes that phases may run concurrently, which matters because concurrent phases produce overlapping vehicle demand.

Because it is the measure of impact the highway authority can actually test. The guidance includes estimated vehicle movements as a required section and notes the peak number of vehicles should also be reported. The peak is often more important than the total, because congestion and safety problems occur at the peak.

It is the point in the programme when vehicle movements are highest, which the guidance says the Outline CLP should include alongside the overall programme. An average daily figure can conceal a fortnight of very heavy movements during muck-away or concrete pours, and that fortnight is what causes complaints.

Approved routes to and from the site, site access arrangements, and local area routing including turn back routes. The guidance notes medium impact sites require a single plan showing the local area routing. Swept path analysis usually sits here, because it is the evidence that the proposed access and turning actually work for the vehicles named.

Frequently yes, because the vehicle routing and site access section has to demonstrate that the vehicles serving the site can physically use the access. A statement that a given lorry can enter and leave is an assertion. A swept path drawing is evidence. Many authorities will not discharge the condition without it.

Measures that reduce the number, timing or effect of vehicle movements. Consolidation, off-site manufacture, freight by rail or water where available, delivery booking systems, and restricting arrivals outside school times are all recognised approaches. The guidance devotes a whole planned measures section to this, differentiated between medium and higher impact sites.

How the commitments will actually be delivered, who is responsible, how compliance will be measured, and how the plan will be updated. This is the section most often written as a paragraph of intent, and it is the section an officer will use to hold the site to account later.

The guidance includes staff travel among its planned measures, including confirmation that safe and secure cycle parking is made available at the construction site. Construction worker trips can exceed delivery trips on a large site, so leaving them out understates your impact.

Most often because something required is missing rather than because something is wrong. Generic template content, no site-specific routing plan, no peak movement figure, no swept path evidence for the access, and an implementation section with no named responsibilities are the recurring gaps. Each one generates a request for information and delays the start on site.

Writing it as a document to satisfy a condition rather than as a plan to run a site. Reviewers can tell the difference immediately. The tell is a plan that describes what will be done without ever saying who does it, when it is checked, or what happens if it is not followed.
