Temporary works in a construction management plan
Construction management plans usually cover lorries and wheel washing well and temporary works badly. These are the items that cause the disputes on a constrained urban site.
Temporary works in a construction management plan are the propping, shoring, facade retention, cranes, hoardings, piling and monitoring that exist only during the build and that affect land and buildings the developer does not own. Most plans submitted to discharge a construction management condition deal with lorry routes and wheel washing in detail and cover all of that in two lines. On a tight urban site the temporary works are what the neighbours actually experience, and they are what generates the complaints, the injunction threats and the stop notices.
What the plan needs to cover on temporary works
A condition requiring a Construction Management Plan usually lists hours of work, deliveries, parking, dust, noise and site security, and then adds a catch-all about details of works affecting the highway. Read the condition wording before writing the document, because the scope varies and there is no point submitting material the condition does not require.
Six temporary works items belong in the plan on almost any constrained site:
- Propping, shoring and any facade retention, with the design responsibility identified
- Crane type, position, radius, and whether the jib oversails land outside the site
- Hoardings, scaffolds, gantries and any occupation of the footway or carriageway
- Piling or foundation method, with the noise and vibration limits proposed
- Monitoring of adjacent structures, with trigger values and the action at each
- Sequencing, so that the authority can see when each temporary condition begins and ends
Temporary works design has its own framework under the recognised code of practice for temporary works procedures, with a temporary works coordinator appointed and a register maintained. The planning document does not need to reproduce that. It needs to confirm the framework exists and to explain the impacts outside the site boundary.
Propping, shoring and facade retention
Facade retention is the highest risk temporary works item on a conservation-led scheme, and it is the one most often reduced to a single sentence. The retained facade has to be restrained against wind and against the loss of the floors that used to prop it, the restraint system needs load paths to a foundation, and movement has to be monitored throughout.
Set out in the plan what is being retained, how it is restrained, whether the restraint is internal or external, and what happens if monitoring shows movement. Where the restraint structure stands on the public highway or over a neighbour's land, say so and identify the consent required.
Support works and shoring to neighbouring walls raise a separate regime. The Party Wall etc. Act 1996 governs notices, awards and surveyors between the parties, and it operates independently of planning. An authority cannot enforce a party wall award, and it will still expect the plan to confirm that the process is being followed, because a scheme that ignores it will stop.
Our note on chimney removal in a conservation area and the stability question covers a smaller version of the same problem, where a shared stack is involved.
Cranes, oversail and land you do not control
There is no right to swing a crane jib over someone else's land. Oversailing without agreement is trespass, and an injunction obtained the week the tower crane is erected is an expensive lesson.
The plan should show the crane position, the jib radius drawn on a plan, and the ownership of everything inside that radius. Where the jib crosses third party land, an oversail licence or agreement is needed, and it is normally paid for. Our note on crane oversailing third party land sets out how those agreements are usually structured.
Four further approvals catch people out:
- Aerodrome safeguarding, where a tall crane sits within a safeguarded area, which may require notification and aviation lighting
- Network Rail or tram operator asset protection approval where the crane can reach railway land, with a strict regime on slew limits
- Highway authority approval where the crane erection or dismantle requires a road closure and a temporary traffic order
- The local authority's own consent where the site adjoins a school, hospital or listed building with particular constraints
Slew limitation and anti-collision systems are the usual mitigation, and the plan should state whether the crane will be left free to weathervane out of hours, because that affects the oversail position when nobody is on site.
Hoardings, scaffolds and highway licences
Anything on the public highway needs the highway authority's permission, and the routes are statutory. The Highways Act 1980 provides for licensing the erection of scaffolding on a highway, for licensing the deposit of building materials or the making of an excavation in a street, and for the requirement to erect a hoarding where building work is carried out near a street. Each licence carries conditions, a fee and usually a charge for the occupied area.
Footway closures and diversions need a separate approval and, where the carriageway is affected, a temporary traffic regulation order that takes weeks to promote. Programme it. A build that assumes a footway closure from week one and applies for it in week one will lose a month.
Two details that matter for the planning document. Hoarding design is a visual matter on a prominent frontage, and authorities in conservation areas often require a specific treatment, sometimes with interpretation panels or artwork secured by condition. And the hoarding line determines pedestrian width, which raises accessibility duties for the authority, so an early conversation about a tight footway is better than a refused licence.
Construction traffic routing sits alongside all of this and is usually a separate document, with the Construction Traffic Management Plan covering routes, swept paths and holding arrangements.
Piling method and vibration limits
Method selection is a planning-relevant choice because it determines the noise and vibration neighbours experience. Continuous flight auger and rotary bored piles are quieter and produce far less ground vibration than driven piles, and on a site surrounded by housing that difference is usually decisive.
State the method, the plant, the expected noise levels at the nearest sensitive facades and the vibration levels as peak particle velocity, assessed against the recognised standards for construction noise and vibration, for building damage and for human response. Then set out the monitoring and the trigger levels.
A workable trigger arrangement has three tiers: an advisory level at which the method is reviewed, an action level at which work modifies, and a stop level at which work ceases pending investigation. Name the levels, name who monitors, and name who can authorise a restart.
Pre-condition surveys of neighbouring properties, carried out before work starts and agreed with the owners, protect everyone. They are not a planning requirement in most cases and they belong in the plan because they are the evidence that settles a later claim.
Monitoring adjacent structures
Monitoring is worth doing properly because it is the only thing that distinguishes movement your works caused from movement that was already happening.
- Precise levelling to fixed datums outside the zone of influence, with a baseline set before any work
- Crack monitors and tell-tales on existing cracks, photographed and dated at installation
- Inclinometers or tilt sensors where a retaining structure or a retained facade is involved
- Groundwater monitoring where dewatering could cause settlement in compressible ground
- A reporting frequency and a named recipient, with an escalation route
Agree the instrumentation and the triggers with the adjoining owners where you can. A neighbour who receives a weekly monitoring summary is a great deal less likely to complain to the authority than one who hears drilling and guesses.
Illustrative example: a five-storey infill between two Victorian terraces, with continuous flight auger piling, a stop level for vibration at the party walls, precise levelling on eight targets across both neighbours, weekly reporting to the owners and a temporary works register maintained by the contractor. Details here are illustrative only.
Conditions likely to reference the plan
Expect the plan to be secured by a condition requiring approval before any work starts, and expect a further condition requiring the approved plan to be adhered to throughout. Where the works affect the highway, expect a condition requiring the licences to be in place, and where a facade is retained, a condition requiring the retention scheme to be approved.
Two practical points on discharge. Submit early, because a construction management condition discharge needs the contractor appointed and the contractor is usually appointed late, and that sequence delays starts more than any other. And where a Structural Survey or a structural method statement is referenced in the plan, submit them together, because an officer cannot assess one without the other.

Frequently asked questions
Can a crane jib swing over a neighbour's land without permission?
No. There is no right of oversail, and doing it without agreement is trespass, which can be restrained by injunction. Show the crane position and jib radius on a plan, identify ownership inside that radius, and obtain an oversail licence where the jib crosses land you do not control.
What licences are needed for a hoarding or scaffold on the footway?
The Highways Act 1980 provides for licensing scaffolding erected on a highway and the deposit of building materials or excavation in a street, and requires a hoarding where building work is carried out near a street. Footway closures and any carriageway occupation need separate approval and often a temporary traffic order.
Does a construction management plan cover party wall matters?
Not as a planning requirement. The Party Wall etc. Act 1996 operates between the parties, with notices, awards and surveyors, and the authority cannot enforce an award. The plan should still confirm the process is being followed, because support works or shoring that ignore it will stop the job.
What vibration limits should a plan propose for piling?
State the method and plant, the predicted peak particle velocity at the nearest structures, and the assessment standards used for building damage and for human response. Then set advisory, action and stop levels, name who monitors, and name who can authorise a restart after a stop level is reached.
When should a construction management plan be submitted?
As early as the information allows, because these conditions usually have to be discharged before any work starts and the plan depends on the contractor's methods. Late contractor appointment is the commonest cause of delay in discharging this condition, so agree the scope with the case officer before the contractor is on board.
