Working hours, wheel washing and complaints in a CMP

A Construction Management Plan is the document that turns "we will be considerate neighbours" into wording a council can enforce. Most plans are secured by a pre-commencement condition, so the construction management plan contents matter twice over: once when the officer decides whether the condition can be worded at all, and again when you apply to discharge it and someone reads what you actually promised. The operational half of the plan, working hours and wheel washing and the complaints route, is where discharge applications usually stall.

Routeing and vehicle numbers sit in a separate document on larger sites. This looks at the controls that govern what happens inside the hoarding.

What the plan is securing

The condition exists because the council has identified a residual harm it cannot control through the permission itself. Dust on washing lines, mud tracked onto a bus route, a cement mixer at 6am on a Sunday. Planning Practice Guidance sets six tests for conditions: necessary, relevant to planning, relevant to the development, enforceable, precise, and reasonable in all other respects. A plan that promises to "minimise disturbance where reasonably practicable" fails the precision test, and an officer who approves it has handed the enforcement team nothing to work with.

So write the plan as a set of commitments a monitoring officer could check on a Tuesday afternoon without ringing you first.

Note that several of the controls people expect to find in a planning condition sit in other regimes. Noisy works can be regulated under sections 60 and 61 of the Control of Pollution Act 1974, statutory nuisance under the Environmental Protection Act 1990, and deposits on the public highway under the Highways Act 1980. Duplicating those powers in a planning condition is one of the commoner reasons a draft condition gets struck out.

Working hours and the exceptions that get agreed

Standard conditioned hours in England cluster around 08:00 to 18:00 Monday to Friday and 08:00 to 13:00 on Saturdays, with no working on Sundays or bank holidays. The exact wording varies by authority and sometimes by ward, so take it from the council's own standard conditions list rather than a previous decision notice on another site.

What matters more is the list of activities you want outside those hours, set out in advance with a reason:

• deliveries of oversized loads that the highway authority will only permit at night
• concrete pours that cannot be interrupted once started
• work on or over a railway or highway that requires a possession or a closure
• emergency works to make the site safe

Each exception should name who authorises it and how neighbours are told. A plan that asks for "occasional flexibility" invites refusal. A plan that says oversized deliveries will be notified to the case officer and to affected occupiers at least five working days in advance, and limited to a stated number across the build, gets agreed.

Quiet periods are worth offering where the neighbouring use justifies them. A school next door means avoiding the loudest activity during exam weeks. A care home means no percussive work before 09:00. Officers remember the applicant who proposed the restriction rather than waiting to have it imposed.

Mud, dust and wheel washing

Depositing mud on the highway is an offence, not a planning matter, which is why councils want the mitigation fixed in the plan before the first lorry leaves. Set out the method rather than the aspiration. A drive-through spray system with a settlement tank suits a long groundworks phase on clay. A jet wash and a hardstanding apron suits a small urban site with two exits a day. A rumble strip alone rarely convinces a highway officer in winter.

Then say who checks it, how often, and what happens when the check fails. Most plans name a site manager, a daily visual inspection of the access and the first 20 metres of carriageway, and a road sweeper on call with a stated response time.

Dust control follows the Institute of Air Quality Management construction dust guidance, which is the framework most environmental health officers use. The practical commitments are damp cutting, no dry sweeping, sheeted stockpiles and loads, water suppression on crushing and screening, wheel-washing at the exit, and no burning of waste on site. Where the site sits within an Air Quality Management Area or close to a school, add real-time monitoring with trigger levels and a stated action if a trigger is breached. Our note on environmental zones and obtrusive light limits covers the equivalent approach for site lighting, which follows the same logic of naming a limit and a check.

Deliveries, storage and the site compound

Draw the compound. A plan with a compound drawing attached is approved faster than one with a paragraph describing it, because the officer can see that materials are not stacked against the boundary fence and that the welfare unit does not sit under the neighbour's bedroom window.

Cover the loading and unloading position, whether any of it happens on the public highway, the number of vehicles that can be held on site at once, and where drivers wait if they arrive early. Early arrivals idling on a residential street generate more complaints than the works themselves. A booking system with a named contact and a marshalled holding point is the answer most highway officers want to see.

Fuel and chemical storage needs bunding and a spill kit. Where the site sits over a Source Protection Zone or within a floodplain, say so and cross-refer to the drainage strategy, because the Environment Agency's interest in the compound is different from the council's.

Noise and vibration by activity

The useful structure is activity by activity rather than a single site-wide number. Demolition, piling, breaking out slabs, scaffolding, and fit-out each produce a different problem, and BS 5228 parts 1 and 2 give the methods for predicting construction noise and vibration.

Where vibration matters, a pre-commencement condition survey of adjoining buildings protects both sides of the argument. The reasoning is set out in our piece on condition grading and defect schedules in a structural survey, and the same photographic record answers most later claims.

Piling method statements are often reserved by a separate condition. Say in the plan that one will be submitted, and name the trigger levels you propose to work to, expressed as peak particle velocity at the nearest structure.

Liaison and the complaints route

This section is short in most plans and it should not be. Give a named site contact, a monitored telephone number that works outside office hours, and an email address that reaches a person rather than a mailbox nobody opens.

Then commit to a process: acknowledgement within one working day, a substantive response within five, a written log of every complaint with the date, the nature of it, the action taken, and the outcome, made available to the council on request. Offer a letter drop to a defined radius before the noisiest phases and before any agreed out-of-hours work. On larger schemes a monthly newsletter and a site liaison meeting with the parish or ward councillor takes most of the heat out of the build.

And keep the log honestly. A discharge application supported by a log showing four complaints and four resolutions reads better than one claiming none at all.

Writing it so the condition can be discharged

Structure the document to mirror the condition. If the condition lists seven matters, use those seven as your headings, in the same order, with the same words. The officer assessing the discharge application is working through a checklist, and anything they cannot find, they will ask for, which costs you eight weeks.

Attach the compound plan, the swept-path drawing if vehicle movements are part of the condition, the wheel wash specification, and the draft neighbour letter. Where a matter cannot be fixed before a contractor is appointed, say what will be fixed and by when rather than leaving a gap. Blank spaces in a submitted plan are read as unresolved rather than flexible.

One honest uncertainty: authorities differ widely on how much detail they want at discharge stage, and a plan sized for a London borough will be over-engineered for a rural district. If you can, ask the case officer which of the seven matters they actually intend to police.
