A site office, a classroom, a clinic annex and a camp block can share a cold-formed chassis and still need different cores, different opening schedules and different readings of temporary versus permanent modular construction.
Relocatable buildings for a contractor compound. Typical external module 6058 × 2438 × 2896 mm. Linked plans step to 3.0 m width when the road permit allows the volumetric body. Wind on an exposed coast has been entered at 45 m/s before release; inland sites do not inherit that number.
Swing-space rooms with a corridor link. A 2021 Ontario sheet used ground snow load 1.5 kN/m² and a wall target of 0.35 W/m²K. Acoustic partitions were specified apart from the external PIR wall so one core did not have to solve both jobs.
Consult rooms and anterooms with a factory sanitary package. Shielded imaging rooms and operating theatres are outside the standard sheet. The 2023 Gulf annex kept medical gas on the site contractor.
Offices, dining support and ablution rows. Northern Chile 2019 used 36 modules with rock-wool walls because of the diurnal swing. Bed-count dormitories need a separate fire strategy; a panel coupon is not that strategy.
Two arguments sit on most WillScot enquiries. Both sides are priced when the inputs exist. Neither side is a default winner.
| Dimension | Volumetric module | Panelized or bolted pack |
|---|---|---|
| Factory completion | MEP preinstallation and lining can leave the plant inside a closed box. | Walls, floors and frames ship dense. More joints close on site. |
| Transport | Often one module per 40-foot flat rack. Road width and escort rules dominate. | A 40HQ can hold several wall sets. The count is method-specific. |
| Crane and yard | Needs a lift plan matched to the lug coordinates. | Lighter lifts, longer assembly, torque records on each joint. |
| Plan freedom | Width is constrained by the shipping envelope. | Plans can step beyond a single box, with more site tolerance risk. |
| Dimension | EPS | PIR | Rock wool |
|---|---|---|---|
| Mass | Lowest of the three at the same thickness. | Still light enough for most volumetric lifts. | Heavier. Check lug reactions again. |
| U-value at 75 mm | Useful in mild climates. Mid-panel figure is not the skirt. | Often the path to about 0.35 W/m²K on heated rooms. | Thicker build to reach the same U-value. |
| Fire discussion | Needs the actual panel classification, not a slogan. | Better foam fire data than EPS in many listings, still not a wall test. | Mineral fibre is the usual pick when the strategy asks for it. |
| Moisture | Closed cell, watch the joints. | Closed cell, watch the joints and the steel thermal bridge. | Fibre can hold water if the facing is cut and left open. |
Shop checks used on the March 2024 WS-2436 unit were a tape and laser survey of length, width and diagonal at 18–25 °C on level stands, plus a thickness gauge on the wall and a mill-certificate reading for coating mass. Four elevations were recorded, lug coordinates photographed, then the pack photo was filed with the revision. That path can be repeated on a sample from a later lot. It is not a wind-tunnel test and it is not a fire furnace test.
Name the use, the country and whether you are comparing a volumetric body with a bolted pack. The desk will answer with one method or with both prices.
