Site Readiness & Installation
Modular building delivery access: HIAB and crane checks
The building fits the site. Can the delivery vehicle reach it, and can the lifting team work there? Resolve both questions before booking transport.
- Route
- Check the loaded vehicle
- Working area
- Confirm the lifting setup
- Final position
- Agree the receiving works
What should you check before booking delivery?
Check modular building delivery access across three areas: the approach route, the vehicle and crane working area, and the final building position. A wide gate or finished base does not establish that the whole operation is feasible. Give the transport and lifting teams current drawings, module information, access measurements, ground records and nearby hazards. Ask them to confirm the proposed method and any additional assessment needed. Record responsibilities, permissions, site preparations and the conditions that could postpone delivery. Start your KC enquiry with the intended use, approximate layout and site postcode; include photographs where available. This guide helps prepare the brief—it is not a lift plan or permission to proceed.
Who this guide is for
- Facilities and estates teamsPlacing a new building on an occupied site.
- Contractors and project managersCoordinating transport, lifting and receiving works.
- Business and venue ownersChecking access through a yard, car park or shared entrance.
- Procurement teamsComparing delivery inclusions and unresolved site costs.
Identify the constraint before choosing the method
Use the table to identify the next assessment, not to select equipment. Review KC’s modular building options and portable cabins alongside the site information: the installation route should be considered while the building brief is still being developed.
| Situation | What to check | Why it matters | Next step |
|---|---|---|---|
| Narrow gate or sharp approach | Loaded vehicle dimensions and the turning path. | Gate width alone does not describe the manoeuvre. | Request a transport access review. |
| Paved yard beside the building | Working space, ground evidence and underground features. | A finished surface is not a capacity assessment. | Ask the lifting planner what evidence is needed. |
| Proposed setup affects a road | Highway authority requirements and traffic arrangements. | These are separate from the building order. | Identify the permission owner and application route. |
| The site must stay occupied | Segregation, emergency access and operational restrictions. | Normal site activity must be addressed in the plan. | Agree arrangements with the site operator. |
On smaller screens, scroll the table horizontally. Keyboard users can focus the table region.
Modular building delivery access starts before the gate
Provide the intended entrance, approach photographs and known restrictions. Include pinch points, low structures, slopes, parked vehicles and changes in level. Mark where photographs were taken and date them. Record measurements only where they can be obtained safely; never enter traffic or approach overhead cables to measure a clearance.
Ask the haulier to assess the actual loaded vehicle, including its route through and out of the site. Do not substitute the bare module dimensions or assume that a previous delivery vehicle establishes access for this one.
Where abnormal-load rules apply, the transporter must address the relevant notifications. National Highways’ abnormal-load guidance explains the ESDAL route-planning and notification system. Confirm the requirements for the actual load and journey; this article does not supply a transport authorisation.
HIAB cabin delivery or a separate mobile crane?
HIAB is a loader-crane brand, not a lifting-capacity description. HIAB’s manufacturer information describes a range of loader cranes. Confirm the actual proposed equipment rather than relying on the brand name in a quotation.
Vehicle-mounted loader crane
Ask the provider to show that the proposed vehicle, crane and working position suit the module and placement. Request confirmation of the information needed from the building supplier, including the lifted configuration and lifting provisions. Do not infer suitability from a photograph of a similar cabin being unloaded.
Separate mobile crane
Ask how the crane and delivery vehicle will be positioned, how their arrivals will be coordinated and what area must remain available. The competent lifting planner should assess equipment selection for the complete operation—not just whether the boom appears long enough.
A narrow entrance is not automatically solved by a crane
For example, a building may fit behind an existing warehouse while the proposed crane position sits in a neighbour’s yard. Before accepting that layout, establish whether that working area is available and can be assessed. This is an illustrative briefing problem, not a verified KC project or a proposed lifting method.
What should a modular building site survey record?
Start with the following information pack. The appointed transport and lifting specialists should determine the survey scope and whether more measurements, records or engineering input are required. Buyer photographs support that process; they do not replace it.
| Record | Information to provide | Question to close |
|---|---|---|
| Site and entrance | Postcode, marked entrance, contact and operating hours. | Is everyone planning for the same access point? |
| Vehicle route | Known restrictions, safe measurements and dated photographs. | Has the haulier assessed the proposed vehicle? |
| Module information | Current drawings and supplier-confirmed lifting information. | Is the plan based on the actual delivered configuration? |
| Working area | Available space, ground records and known buried features. | What further assessment or preparation is required? |
| Surroundings | Overhead lines, buildings, boundaries and occupied areas. | Who resolves each hazard or third-party interface? |
| Receiving works | Current base layout, levels and readiness records. | Who confirms that the agreed installation stage can start? |
Start with your building brief and access photographs
Send the use, approximate layout and site postcode. Identify access concerns early so the building proposal can record what needs further investigation.
This starts a building enquiry. It does not book a site survey, crane or transport service.
Crane access for modular buildings: check the working area
Separate the assessment of the building foundations from the assessment of the transport and lifting areas. Share available records of drains, chambers, buried services, recent trenches and ground alterations. Ask the planner which locations need further investigation; a paved finish is not evidence of what lies beneath it.
HSE’s lifting-planning guidance addresses equipment stability, positioning, proximity hazards and the environment. The proposed operation needs competent assessment. This article does not specify ground-bearing values, outrigger support arrangements or equipment capacities.
Overhead lines need a separate decision
Flag lines across the approach and around the work area. Do not identify a cable as safe from its appearance. HSE’s overhead-line guidance says to consult the line owner and treat lines as live unless the owner establishes otherwise. Danger can arise without direct contact. The relevant specialists must resolve the precautions; do not use a generic clearance from an online article.
Crane hire and a contract lift are not the same scope
HSE’s construction lifting guidance distinguishes crane hire from a contract lift. Under crane hire, planning, supervision and execution remain with the user unless the crane company expressly takes those responsibilities under a contract lift.
Ask the provider to state the arrangement in writing. Identify who supplies site information, prepares the work area, plans the lift and supervises it. Do not assume that hiring equipment with an operator transfers every responsibility, or that a contract lift removes the need to provide accurate site information.
Occupied sites, public roads and other permissions
Tell the team about staff, pupils, visitors, deliveries and emergency routes that must be considered. HSE’s site traffic guidance emphasises separating pedestrians and vehicles and reducing reversing. Agree the managed work area with the site operator; an early arrival time is not, by itself, a traffic plan.
For work affecting a highway, identify the responsible authority and required arrangements before booking. Transport for London’s licensing guidance illustrates how crane operations and highway occupation are treated on its network. Its process is not a nationwide licence or a standard timetable.
Flag nearby aerodromes and other sensitive infrastructure. Ask the lifting team to check whether CAA crane notifications or other specialist coordination are relevant. Do not treat a building’s planning permission as approval for all delivery activities.
Agree a readiness check before transport is committed
Use a dated action record showing each outstanding item, its owner and the evidence needed to close it. Ask who authorises mobilisation, and how changes will be communicated.
- Information: confirm the current layout, delivery configuration and agreed method.
- Site: confirm the agreed preparations, access arrangements and receiving works.
- People and permissions: confirm the named teams, required permissions and site coordination.
- Changes: agree how weather, ground changes, obstructions or unavailable working areas trigger reassessment.
Ask the planner to define relevant operating limits and stopping decisions. Do not press for an improvised setup simply because the building has arrived. Record the commercial process for postponement separately from the safety decision.
Compare the delivery package—not just a crane rate
Ask whether the quotation covers transport, route review, survey work, lifting arrangements, site preparation, traffic management, permits, positioning and installation. Mark each as included, excluded, provisional or by others.
Clarify waiting time, aborted visits, storage, remobilisation and changes to the agreed route. Check the VAT basis and quotation validity. Delivery, module assembly, service connections and readiness for occupation should remain distinct scope lines. The wider KC delivery and installation guide provides the installation overview.
What KC needs to quote
For Stoke-on-Trent, Staffordshire or another UK location, provide the actual delivery site—not only a head-office address. Send the available information and mark unknowns.
- Building: intended use, approximate size, room schedule and temporary or permanent requirement.
- Location: postcode, marked entrance, proposed building position and named site contact.
- Timing: target occupation date, site working hours and any restricted delivery windows.
- Access: photographs, known restrictions, available working areas and third-party boundaries.
- Site works: foundations, groundworks, service routes and drainage status.
- Specification: finish expectations, required installation scope and budget direction where available.
- Records: plans, sketches, surveys, ground information and approval status.
A preliminary enquiry does not need a guessed crane size. KC can review the building brief and identify access questions that need specialist confirmation.
Delivery-access questions
How wide must access be for a portable cabin delivery?
There is no universal gate width for every portable cabin delivery. Give the haulier the proposed unit and entrance information, then ask them to assess the loaded vehicle and its route. Turning space, the approach angle, overhead restrictions and the exit can matter as well as the opening itself. Photographs and safe measurements help describe the site, but they are not access approval. Do not widen an entrance or remove structures until the relevant permissions and agreed plan are in place.
Does every modular building need a separate mobile crane?
No single lifting arrangement suits every project. A vehicle-mounted loader crane may be proposed, or delivery and lifting may use separate equipment. Ask the competent provider to assess the actual module, working area and final position before the method is fixed. Compare the agreed scope, not just the equipment label. For a larger linked building, also ask how the vehicle arrivals and installation sequence will be coordinated. This guide does not confirm that either arrangement is suitable for your site.
Can a HIAB lift a cabin over an existing building?
That question needs a site-specific assessment, not an assurance based on a photograph or advertised reach. Give the lifting specialist the actual module information, obstruction details, available working areas and intended final position. Ask them to establish whether an acceptable method can be planned, including the implications for occupied areas and neighbouring property. The answer may require a different arrangement or further investigation. Do not assume that a longer boom or a larger crane automatically resolves the site constraints.
Is a concrete car park suitable for crane setup?
Its appearance does not establish suitability. Provide available ground and construction records, together with information about chambers, services, previous excavations and other buried features. Ask the lifting team what assessment is needed for the proposed equipment and its working position. Keep this separate from confirmation that the building foundations are ready. A car park accommodating everyday traffic is not a substitute for the project assessment. Any required preparation or support arrangement must be specified by the appropriate competent specialists.
Who arranges the lift plan and site permissions?
The appointments and agreed scope should identify the responsible parties before mobilisation. Ask who plans and supervises lifting, who provides the site information, and who obtains each relevant permission. Crane hire and a contract lift allocate some responsibilities differently, so have the provider confirm the arrangement explicitly. Keep highway requirements and third-party access questions visible rather than hiding them under a general delivery allowance. An enquiry or a delivery date is not evidence that these actions have been completed.
How much does modular building delivery cost?
A useful quotation needs the actual site and a defined package. Ask for transport, lifting, surveys, site preparation, traffic arrangements, permits and positioning to be identified. Check what is excluded or provisional, and clarify waiting time, postponement, storage and remobilisation terms. Compare quotations on the same scope and VAT basis. A rate for a crane or a journey is not necessarily the total delivery cost. Send KC the building brief and access information so unresolved items can be identified before pricing is finalised.
