Drafted construction management plans and the highway input

A construction management plan secured by condition has two kinds of content, and only one of them can sensibly be drafted in advance. The procedural and mitigation content is largely standard: hours of work, dust suppression, noise control to BS 5228, waste handling, hoarding, site security, operative parking, community liaison. The routing and licensing content is not standard at all, because it depends on which streets the local highway authority will accept construction traffic on, what restrictions are already in force, and what licences the authority will grant under the Highways Act 1980. A draft can set out the first category properly and frame the second. It cannot decide it.

Knowing which is which is what makes the difference between a plan discharged first time and three rounds of correspondence.

What a plan has to cover

Conditions vary in wording, but the content authorities expect is reasonably consistent:

• site set-up, including hoarding lines, gates, welfare, storage and crane positions
• hours of work and of deliveries, with any variation for concrete pours or abnormal loads
• construction vehicle routing to and from the strategic or principal road network
• the number and type of vehicle movements by phase, with peak daily figures
• loading, unloading and turning arrangements, within the site where possible
• operative parking and a strategy to discourage parking on surrounding streets
• wheel washing and road sweeping, with trigger arrangements
• dust, noise and vibration control measures and any monitoring
• waste and materials storage, and recycling arrangements
• pedestrian and cycle management past the site, including any diversion
• emergency arrangements and a named contact for residents
• a liaison and complaints procedure

Where a condition names a construction traffic plan specifically, the traffic content is split out into a separate Construction Traffic Management Plan and the broader site management content stays in the Construction Management Plan. Read the condition wording before deciding which document you are producing.

Routing, and who decides it

Routing is where applicants assume too much. The planning authority imposes the condition, but the content is agreed with the local highway authority, and in a two-tier area that is the county council rather than the district that granted permission. On or near the strategic road network, National Highways has an interest too, and in London the borough and Transport for London both engage depending on the road.

What the highway officer is weighing is not on any form. Which residential streets have bus routes, where the school crossing patrols stand, which junction has a swept path problem for a 16-metre articulated vehicle, which bridge has a weight restriction, which street has an existing restriction from another development's plan running at the same time. None of that is in a dataset you can draft from.

So the sensible approach is to propose a route with reasons, mark the constraints you can identify, and treat the proposal as an opening position. A plan that presents a route as settled and then has to be rewritten loses more time than one that offers two options and asks which is preferred.

Wheel washing, hours and dust

This content is standardisable, and a drafted plan should carry it in full.

Hours typically follow the authority's standard for construction, often around 8am to 6pm on weekdays with reduced Saturday hours and no Sunday or bank holiday working, and the plan should state the proposed hours rather than refer to the condition. Deliveries are frequently restricted more tightly than working hours, particularly near schools, so offer delivery windows that avoid school arrival and departure times.

Wheel washing needs a specification rather than a statement of intent: the type of installation, its position relative to the exit, the water supply and discharge arrangement, who inspects it and how often, and the road sweeping arrangement that backs it up. Dust control follows the published construction dust guidance, with measures scaled to the sensitivity of the surroundings and to the activities on site, and the plan should say which risk category the site falls into and why.

Noise and vibration work to BS 5228 Parts 1 and 2, with predicted levels for the noisiest activities at the nearest receptors and the mitigation that brings them down. On a tight urban site, agree a section 61 prior consent under the Control of Pollution Act 1974 rather than relying on the planning condition alone.

Highway licences that sit outside the permission

These are separate consents, obtained from the highway authority, and no planning condition grants them. Allow time and budget:

Temporary traffic orders are the ones that catch programmes out, because advertising and notice periods can run to several weeks and some authorities have a queue. Crane oversail of neighbouring land is a private law matter and needs the neighbour's agreement, which is not a licence at all.

Where a draft gives a usable framework

An AI-assisted draft earns its place on the parts of the document that are repetitive, policy-anchored and structural. It can produce the full section structure that authorities expect, the standard mitigation text for dust, noise, waste and wheel washing, the liaison and complaints procedure, the regulatory framework with the right statutory references, and a schedule of the licences the project will need. It can insert a flag wherever a site-specific fact is missing instead of inventing one, which is how the drafts are built.

That saves the hours otherwise spent assembling boilerplate, and it leaves the time for the parts that need judgement. The pattern is the same one that shows up across report types: drafts get structure right and evidence wrong, and a plan is mostly structure with a few decisive evidence points.

PlanScope provides AI-assisted draft reports for planning applications. Reports should be reviewed before submission. We do not guarantee planning approval.

What the highway authority adds

Expect the officer to add or change four things. The route, with specific streets named and others prohibited. A holding or call-off arrangement so that vehicles do not queue on the public highway waiting for a slot. Swept path drawings at the site access and at any awkward junction on the route, prepared by a transport consultant using the design vehicle the site will actually receive. And a condition survey of the highway before and after, with a commuted sum or bond where damage is likely.

Treat all four as foreseeable and price them. A swept path exercise and a condition survey are modest costs that remove the two most common reasons a plan is returned.

Discharging the condition first time

1. Read the condition and list every element it requires, in its own words.
2. Identify whether it is pre-commencement, and if it is, check the programme, because a pre-commencement condition needs the applicant's written agreement under section 100ZA of the Town and Country Planning Act 1990 before it can be imposed and cannot be side-stepped afterwards.
3. Speak to the highway officer before submitting, with a draft route and a question rather than a finished document.
4. Submit the plan with the swept paths, the condition survey and the licence schedule attached.
5. Allow the full determination period for the approval of details application, plus time for one round of comments.

Applications are often returned for missing documents rather than weak ones, which is the same mechanism behind why planning applications are returned as invalid. Where the plan needs professional input on swept paths or acoustics, a reviewer from the professional directory can check and sign off the draft before it goes in.

This is general guidance, not legal advice; check the position with your local planning authority or a qualified professional before relying on it.
