CLP Guide
Outline & Detailed Construction Logistics Plans for London Projects
A Construction Logistics Plan (CLP) sets out how construction-related vehicle movements, deliveries, site access and logistics will be managed throughout a development.
Seneca Services prepares Outline and Detailed Construction Logistics Plans for developers, architects, planning consultants and contractors, including planning-stage submissions prepared before a Principal Contractor has been appointed.
Our CLP work is led by a current CLOCS CLP Advanced Practitioner – Practitioner ID 00344.
What is a Construction Logistics Plan?
A Construction Logistics Plan provides the framework for understanding and managing the movement of construction vehicles, materials, waste and servicing activity to and from a development.
The purpose is not simply to describe deliveries. A well-prepared CLP should establish a realistic logistics strategy that considers the construction programme, vehicle routing, site access, loading and unloading, sensitive receptors, road safety, congestion and measures to reduce the impact of construction activity.
The level of detail should reflect the scale of the development, the surrounding highway network and the requirements of the relevant planning and highway authorities.
Outline and Detailed Construction Logistics Plans
Outline Construction Logistics Plan
An Outline Construction Logistics Plan is normally prepared during the planning and design stage and may accompany a planning application.
At this stage, detailed contractor information may not yet be available. The OCLP therefore establishes the proposed logistics strategy using the available design information, construction programme, anticipated methodology and reasonable project assumptions.
Its purpose is to demonstrate that construction logistics have been considered at planning stage and that the development can be serviced in a safe and workable manner.
Detailed Construction Logistics Plan
A Detailed Construction Logistics Plan is normally prepared during the pre-construction stage, once more detailed contractor and construction information is available.
The Detailed CLP develops the principles established through the planning process into a more detailed and implementable logistics strategy, incorporating confirmed site arrangements, vehicle movements, delivery procedures, routing, management measures and monitoring requirements.
Where an Outline CLP has already been approved, the Detailed CLP should normally develop and refine those agreed principles rather than replace them with a completely different strategy.
When is a Construction Logistics Plan Required?
A Construction Logistics Plan may be required to accompany a planning application, support a Transport Assessment, satisfy a planning condition or Section 106 obligation, or provide detailed construction logistics information before works commence.
The requirement will depend on the scale and location of the development, the surrounding highway network, the anticipated construction impacts and the requirements of the relevant planning and highway authorities.
The planning condition, local-authority guidance and any pre-application advice should therefore be reviewed before the scope and level of detail of the CLP are confirmed.
What Should a Construction Logistics Plan Cover?
The content of a Construction Logistics Plan should be proportionate to the project, the stage of the development and the requirements of the relevant planning and highway authorities.
Depending on the project, a CLP may address:
site and development information
local context, constraints and sensitive receptors
construction programme and methodology
vehicle routing and site access
site logistics and loading arrangements
strategies to reduce construction impacts
planned logistics measures
estimated construction vehicle movements
delivery management
implementation, monitoring and updating
The document should clearly distinguish between confirmed arrangements and planning-stage assumptions that require later contractor confirmation.
Preparing a CLP Before the Principal Contractor is Appointed
An Outline Construction Logistics Plan can be prepared before a Principal Contractor has been appointed.
At planning stage, Seneca Services can work with the developer, architect, planning consultant and wider design team to establish the most realistic logistics strategy using the information available.
This may include proposed site access, vehicle routing, loading arrangements, construction phases, likely vehicle types and anticipated site logistics.
Where contractor-specific information is not yet available, reasonable assumptions can be identified clearly for later review and confirmation.
The objective is to prepare a realistic and implementable planning-stage document rather than a generic submission that needs to be substantially redesigned after contractor appointment.
Vehicle Routing, Site Access and Swept Path Analysis
The CLP should identify appropriate strategic and local routes, access and egress arrangements, loading and unloading locations, potential conflicts and any routes that should not be used by construction traffic.
Depending on the site and vehicle types, swept path analysis may be required to demonstrate that proposed construction vehicles can safely enter, manoeuvre within and leave the site.
Seneca Services can coordinate the CLP with project-specific routing plans, site logistics drawings and swept path analysis where required.
Construction Vehicle Movement Forecasting
Construction vehicle movements should be estimated in a manner that is realistic and proportionate to the development.
The forecast may consider the construction phases, anticipated materials and waste movements, likely vehicle types and capacities, construction methodology, programme duration, peak construction activity, delivery restrictions and the capacity of the site to receive vehicles.
Where detailed contractor information is not yet available, vehicle movements may be estimated using an appropriate planning-stage methodology and refined as the project develops.
The forecast should also consider whether the site can safely accommodate the anticipated peak level of deliveries and collections.
Planned Measures and Reducing Construction Impacts
A Construction Logistics Plan should consider measures that can reduce the impact of construction activity on the surrounding community and highway network.
Depending on the project, these may include delivery scheduling, avoidance of peak periods, designated vehicle routes, holding or call-off arrangements, consolidation, appropriate vehicle selection, off-site manufacture, material re-use, smart procurement, collaboration with neighbouring sites and workforce travel planning.
The measures proposed should be appropriate to the particular development and capable of being implemented and monitored, rather than included simply as generic commitments.
TfL and CLOCS Construction Logistics Planning Guidance
Transport for London (TfL) and Construction Logistics and Community Safety (CLOCS) have developed Construction Logistics Planning guidance to provide a consistent framework for preparing and assessing Construction Logistics Plans.
The guidance distinguishes between Outline CLPs prepared during the planning and design stage and Detailed CLPs developed during the pre-construction stage, with the level of detail increasing as the project and contractor arrangements become more defined.
The TfL/CLOCS approach considers matters including the construction programme and methodology, vehicle routing and site access, measures to reduce construction impacts, estimated vehicle movements and arrangements for implementation, monitoring and updating.
Seneca Services prepares project-specific CLPs with reference to the relevant TfL/CLOCS framework together with the particular requirements of the local planning and highway authorities.
From Outline CLP to Detailed CLP
The Outline CLP should establish a workable logistics framework at planning stage.
Once the Principal Contractor is appointed, the strategy can be reviewed against the confirmed construction programme, methodology, site setup, procurement arrangements and delivery requirements.
The Detailed CLP can then replace planning-stage assumptions with project-specific information and confirm the arrangements that will be implemented during construction.
This continuity can reduce duplication, avoid unnecessary redesign and help ensure that the logistics principles considered during planning remain practical when the works are carried out.
Implementation, Monitoring and Updating
Once approved, the Construction Logistics Plan should form the agreed basis for managing construction logistics during the works.
The Principal Contractor should implement the approved routing, access, delivery and logistics arrangements and keep the document under review as the project progresses.
Depending on the project and local-authority requirements, monitoring may include vehicle movements, delivery performance, route compliance, complaints, incidents and other relevant logistics information.
Where material changes to the approved logistics strategy are proposed, the CLP may need to be reviewed, updated and, depending on the planning condition and local-authority requirements, re-submitted or re-approved before those changes are implemented.
Information Needed to Prepare a CLP
The information required will depend on the stage of the project and the relevant planning or highway authority requirements.
Typical inputs may include:
planning application, planning condition or Section 106 requirement
site address and development description
relevant planning and highway authority guidance
architectural and site drawings
proposed site access arrangements
construction programme
anticipated construction methodology
vehicle types and sizes
loading and unloading arrangements
construction traffic routes
details of nearby sensitive receptors
contractor information where available
existing Transport Assessments, CMPs or related documents
Where some information is not yet available at planning stage, Seneca Services can identify reasonable assumptions and clearly record the details that require later confirmation.
Coordinated Construction Planning Support
Construction Logistics Plans often sit alongside other planning and construction-management requirements.
Seneca Services can coordinate related documentation through a single point of contact, which may include Construction Management Plans, Construction Traffic Management Plans, Site Construction Management Plans, neighbour consultation, swept path analysis and logistics drawings, Air Quality & Dust Management Plans, Construction Noise and Vibration Assessments and Section 61 Prior Consent.
Where specialist technical reports are required, Seneca Services can coordinate appropriately qualified consultants as part of the wider project delivery.
This can help reduce duplication, improve consistency between documents and reduce the coordination burden on the project team.
How Seneca Services Can Help
Seneca Services prepares project-specific Construction Logistics Plans for planning applications, planning-condition discharge and pre-construction requirements.
We can assist from the early planning stage, including where a Principal Contractor has not yet been appointed, and develop the logistics strategy as more detailed project information becomes available.
Our service can include Outline Construction Logistics Plans, Detailed Construction Logistics Plans, vehicle routing plans, site logistics layouts, swept path analysis, construction vehicle movement forecasting, review of TfL/CLOCS and local-authority requirements, and coordination with related construction-planning documentation.

Frequently Asked Questions
What is the difference between an Outline CLP and a Detailed CLP?
An Outline CLP is normally prepared at planning stage and establishes the proposed logistics strategy using the information available at that time.
A Detailed CLP is normally prepared later, once contractor and construction information is available, and develops those principles into a detailed and implementable logistics plan.
Can an Outline CLP be prepared before a contractor is appointed?
Yes. An Outline CLP can be prepared using the available design information, anticipated programme, proposed site logistics and reasonable project assumptions.
Contractor-specific details can then be confirmed and incorporated at Detailed CLP stage once the Principal Contractor has been appointed.
Does a Construction Logistics Plan include swept path analysis?
Swept path analysis may be required where the planning or highway authority needs evidence that proposed construction vehicles can safely access, manoeuvre within and leave the site.
The requirement will depend on the site layout, access constraints, proposed vehicle types and the expectations of the relevant authority.
Where required, Seneca Services can coordinate swept path analysis and site logistics drawings as part of the wider CLP submission.
Does a Construction Logistics Plan include construction vehicle forecasts?
Yes. A Construction Logistics Plan will normally include an estimate of construction vehicle movements, often broken down by construction phase and vehicle type.
The forecasting methodology should reflect the level of project information available and should produce realistic vehicle numbers that can be reviewed against the capacity of the site, the proposed delivery arrangements and the surrounding highway network.
Where more detailed contractor information becomes available, the forecast can be refined and incorporated into the Detailed CLP.
Can a Construction Logistics Plan be updated after approval?
Yes. A Construction Logistics Plan should continue to reflect the logistics arrangements being implemented on site.
If the construction programme, site setup, access arrangements, vehicle routing or delivery strategy changes materially, the CLP may need to be reviewed and updated.
Where the CLP has been approved through a planning condition, Section 106 obligation or other local-authority process, any material revision should be considered against the relevant approval requirements before the revised arrangements are implemented.
Can Seneca Services prepare both the Outline and Detailed CLP?
Yes. Seneca Services can prepare the Outline CLP at planning stage and subsequently develop it into the Detailed CLP once contractor and construction information becomes available.
This provides continuity between the planning-stage logistics principles and the arrangements ultimately implemented during construction, helping to reduce duplication and avoid unnecessary redesign later in the project.
Discuss Your Construction Logistics Plan Requirements
If you need an Outline or Detailed Construction Logistics Plan for a planning application, planning condition or pre-construction requirement, Seneca Services can review the project requirements and prepare a proportionate, project-specific CLP.
We can also advise on related vehicle-routing, swept-path, construction-management and environmental documentation where these requirements overlap.
