Temporary construction accesses and their conditions

A temporary construction access is a permanent-looking piece of engineering with a short consented life, and the conditions attached to it are where the money sits. Forming a bellmouth, laying a haul road, opening a hedge and then putting all of it back costs real sums, and the reinstatement obligation is frequently discovered at the point the contractor wants to leave site.

Get three things settled before the main application is submitted: whether the temporary access needs its own permission, what licence the highway authority requires for the works in the highway, and precisely what "reinstate" means in the condition.

When a temporary access needs its own permission

Forming a means of access is development, and so is the engineering work behind it.

Where the temporary access serves a development that is itself being applied for, the cleanest route is to include it in that application. Show it on the site plan, describe it in the description of development, and give it a drawing of its own. That converts an argument into an approved drawing.

Where the access is needed before the main permission is in place, or serves land outside the red line, two other routes exist.

Part 4 of the General Permitted Development Order 2015 permits works required temporarily in connection with, and for the duration of, operations being carried out on that land or on land adjoining it. That right can cover a haul road, site compound works and associated temporary structures, and it carries conditions requiring removal and reinstatement of the land when the operations are complete. It is narrower than contractors assume, and it does not authorise works within the public highway.

Otherwise the access needs its own planning application, usually for a temporary period expressed in years.

Licences and agreements for works in the highway

Planning permission does not authorise anything within the highway. That is a separate regime with separate timescales.

Forming or altering a vehicle crossing over a footway or verge requires the highway authority's consent under section 184 of the Highways Act 1980. Larger works to the carriageway, including a new bellmouth, a right turn lane or a change to a kerb line, are handled under a section 278 agreement, which involves technical approval, a bond and inspection fees.

Where the works affect traffic, a temporary traffic regulation order may be needed, and those have statutory notice periods that cannot be compressed.

Programme these first. A section 278 agreement with technical approval and a bond routinely takes longer than the planning application it accompanies, and a contractor standing at a locked gate is an expensive way to discover that.

Skips, scaffolding and hoarding on the highway each need their own licence, and those are usually straightforward provided somebody applies for them.

Visibility at a temporary entrance

Temporary does not mean a lower standard.

The highway authority applies the same approach to visibility at a construction access as it would at a permanent one, derived from measured speeds rather than the posted limit. Our article on visibility splays and where x and y distances come from sets out how the geometry is built up, and Manual for Streets or DMRB and which applies covers which design document governs.

Two features of construction traffic push the requirement upwards rather than down.

Vehicles are slow and long. A loaded eight-wheeler pulling out of a field entrance takes far longer to clear the carriageway than a car, and the visibility requirement reflects the time needed rather than a standard vehicle.

Vehicles are dirty. Mud carried onto the carriageway reduces skid resistance, which is why wheel washing and a bound surface on the first stretch of the access appear in almost every condition.

Where visibility cannot be achieved from the geometry alone, the fallback is management: a banksman, a temporary speed limit, advance warning signage, or restricting the access to left in and left out. Propose the management measures yourself rather than waiting for the highway authority to impose something less workable.

Routing, hours and neighbour amenity

Construction traffic generates more complaints than the finished development ever will, and councils know it.

Expect a Construction Traffic Management Plan condition requiring approval before any work starts. It should cover the agreed route from the strategic road network to the site, the hours during which deliveries may arrive, vehicle sizes, the number of movements expected at each phase, the arrangements for abnormal loads, and what happens when a driver ignores the route.

That last point is worth taking seriously. But a routing plan with no enforcement mechanism is only a wish. Site rules that require hauliers to sign up to the route, a delivery booking system and a complaints log with a named contact are what make it real.

Wider site management questions, including dust suppression, noise from plant, working hours, parking for operatives and site lighting, belong in a Construction Management Plan. Councils often ask for both documents and are happy to receive one that covers everything, provided the traffic content is complete.

Conditions requiring removal and reinstatement

Read the reinstatement condition word by word before you accept it.

The questions to settle are these. What is the trigger, first occupation, completion of the last unit, or a fixed date. What must be removed, the surfacing only or the sub-base as well. What must be reinstated, and to what specification. Is the hedgerow to be replanted, and if so at what size, density and with what replacement period. Who signs off completion.

Photograph the existing condition of the verge, hedge, kerb and carriageway before anything is opened. A dated condition survey agreed with the highway authority at the outset settles almost every argument about dilapidation at the end. Without one, the default assumption is that any damage within the working area is yours.

Where the access crosses the root protection area of a retained tree, the reinstatement condition will interact with the arboricultural method statement, and a no-dig construction that was approved for the temporary access may need to be lifted carefully rather than excavated.

Keeping the temporary access separate from the permanent one

Many schemes drift into treating the construction access as the finished access, and that causes two problems.

The first is design. An access laid out for a rigid tipper is wider, straighter and more visible than the residential access the scheme was consented with, and leaving it in place changes the character of the frontage.

The second is consent. The permission approved a temporary access and a separate permanent one. Retaining the temporary access without applying for it is a breach.

Draw them separately, number the drawings separately and label them clearly. Where you want the temporary access retained, apply for it as a variation while the site is still active rather than as a retrospective application after the last unit sells.

Extending a temporary access beyond its permission

Construction programmes slip. A three year temporary permission on a five year build is a problem that has to be solved in advance.

Where the access was consented for a temporary period, the routes are an application under section 73 of the Town and Country Planning Act 1990 to vary the time condition, or a fresh application for a further temporary period. Section 73 is usually quicker, and it keeps the original permission intact.

Apply before the period expires. Once the condition has been breached, the council is dealing with an unauthorised access rather than an extension request, and the tone of the conversation changes.

On a phased scheme, ask for the temporary access period to be tied to a completion trigger rather than a calendar date at the point of the original permission. Officers are generally receptive to that argument when it is made at the drafting stage and much less so afterwards.
