As the construction phase of any development has an effect on the environment of the local community as well as the safety and congestion of both the local and regional road networks; a CLP addresses these concerns and strives to reduce their impact through planned measures agreed with both the Council and the Supply Chain.
The vehicle movements during each phase of the project are predicted so that the council can see the peak periods / times and can check that when combined with other local construction sites, the vehicle movements are within their local traffic management limits.
The document predicts the type and quantity of vehicles that will be used during each phase of the project, the routes that will be used to and from the site, any alterations to the road network that may be required, for example, lane closures, parking suspension etc. The CLP will also consider how the number of vehicle movements could be reduced by using alternative methods of delivery, or the use of consolidation centres.
In addition to vehicle movements, the CLP also describes the designated delivery route, how the Delivery Management System will work, whether there will be a Consolidation Centre used, if there is a vehicle holding area, a staff travel plan and how this will be implemented. The document will describe how the site will interact with other nearby sites to reduce congestion and also detail how materials will be reused in order to reduce the number of vehicle movements.
Why is that important that a CLP is treated as “LIVE”?
It is important that Principal Contractors don’t just file the CLP when the Planning Condition has been satisfied but actually do treat it as “LIVE” because the Council will!
Change of Phase
Significant Changes to Project
Every 3 months
e.g. From Ground / Sub Structure to Superstructure
e.g. A long delay due to an archaeological find and a report required.
Starting from the first delivery and continuing to the last collection.
The Councils use the vehicle movements predicted in a CLP:
If the vehicle movements from the CLP are inaccurate, then this can have dramatic effects on traffic congestion, in fact HS2 insist that the actual vehicle movements are within 10% of the predicted figures in the CLP.
The Supply Chain needs to be made aware of the designated delivery routes which will be agreed with the council and highlighted in the CLP.
Unless materials are from local suppliers, these deliveries will be requested to use strategic routes best suited to heavier traffic. This way they will cause less congestion and lower emissions in the local area.
Ensuring that the Supply Chain adhere to the CLP helps reduce the number of complaints received by both the Principal Contractor and the Council.
With Air Quality being a major issue and frequently in the news, the Councils are becoming more and more concerned about the number of construction vehicles that are on the road at any time and are therefore becoming more effective at checking that the CLP is accurate and being complied with.
Council departments are linking together, so when construction sites are checked by the Environmental Officers for compliance with Non Road Mobile Machinery (NRMM) regulations, they are also checking to see that the CLP is being reviewed and updated regularly as well as being complied with.
Initially the Council will give advice and warnings, because they want Principal Constructors to realise that a CLP is a “LIVE” document.
However, Councils do have the power to issue a closure notice on a site if there is persistent noncompliance.
WPSCC can compile a CLP to discharge the Planning condition.
