A temporary building may provide additional space for storage or operations, but its suitability depends on the site, use and design. “Temporary” should not be treated as meaning exempt from planning, structural or safety requirements.
Define the operational requirement
Record the activity, occupancy, storage, access and period of use. Identify what environmental conditions the contents and users need. A structure intended for dry storage may not provide the conditions required for occupied work or sensitive equipment.
Measure the usable internal space rather than comparing external dimensions alone. Check openings, vehicle routes, separation from other buildings and the area needed for installation and removal.
Check the site and structural basis
Ask a competent designer or supplier to assess ground conditions, foundations or anchorage and the loads relevant to the location. Do not assume that a tent can be installed safely on almost any surface with little preparation.
HSE’s temporary works guidance explains the importance of design, installation and maintenance for foreseeable loads. Confirm how the principles apply to your proposed arrangement and operations.
Confirm approvals before installation
Ask the local planning authority about the site and intended use. The government’s planning guidance explains that permitted development rights have limits and conditions. Do not apply a single duration or floor-area rule to every temporary structure.
Compare the full cost
Include delivery, ground preparation, installation, services, inspections, repairs, hire duration and removal. Identify responsibility for reinstating the site. Ask what happens if the intended period of use changes or the structure cannot be operated in particular conditions.
Plan operation and handover
Establish inspection arrangements, operating limits and responsibility for weather-related decisions. Consider escape, fire safety, vehicle movement and protection of neighbouring areas with competent advisers. Retain the design information and instructions needed by the person managing the structure.
When comparing suppliers, use the same brief and ask for written exclusions. A fast installation is only one part of the decision; a temporary facility still needs a clear plan for its whole period of use.
