How Are Modular Homes Delivered and Installed? From Factory Gate to Set Day

A modular home leaves the factory as finished modules; walls, roof, windows, wiring, plumbing and most interior finishes already in place. The sections travel by road as wide loads and a set crew joins and weatherproofs them on the prepared foundation (in the ifHaus system, with no crane or heavy machinery), and trades connect the utilities. On a typical single-family project the site phase is measured in days: transport 1–3, the set itself 3–5, connections and finishing a few more.

Everything difficult about the process happens before the trucks roll: the foundation must be finished and dimensionally exact, the route must be cleared for wide loads, and the unloading area must be planned. Delivery is not where modular projects go wrong; preparation is.

Modules ride on flatbed or lowboy trailers, wrapped against weather. Because module widths typically exceed standard lane limits, they move as permitted wide loads: route surveys, movement permits, sometimes escort vehicles and night-hour windows. Transport pricing follows distance and dimensions, which is why the delivery radius is a real line in the modular cost equation.

For overseas projects there is an ocean leg first: modules are secured for marine transport, shipped as breakbulk or in containers depending on dimensions, and cleared through customs at the destination port. Mediterranean to North American ports typically runs four to six weeks on the water; the Canada guide walks the border-side lines in detail.

The defining efficiency of modular construction is that the site and the factory run in parallel. While the modules are on the line, the plot gets its ground survey, foundation, and utility stub-outs. By the time the modules arrive, the foundation has cured and been checked against the module drawings.

The checklist before delivery day is short but strict: foundation finished and level within tolerance, anchor points placed per the engineering, access route cleared and firm enough for the trucks, and the unloading area planned. A one-hour site meeting a week before delivery prevents most of what could go wrong.

Set day is the visible magic: the crew places each section on the foundation, aligns it, bolts it to the anchors and to its neighbours, and closes the module-to-module joints. A single-storey home of two to four modules typically sets in one to two days; connections, roof ridge closing and weatherproofing bring the on-site structural phase to three to five days.

The structural system earns its keep here. ifHaus's load-bearing composite panels go through lifting and trucking with their geometry intact (doors still square, joints still true) which is precisely the stress test that reveals the difference between framing systems.

We documented a real three-week project (foundation to handover, day by day) in our installation diary; it remains the most honest answer to "what actually happens on site."

After the set, trades connect electricity, water and sewage to the stub-outs, finish the module joints inside, and complete any site-installed items. The municipal inspector checks the site works (foundation, connections, egress) while the factory-built portions are covered by the certification label they arrived with. Then the punch list, the cleaning, and the keys.

If you are pricing this end to end, remember the framing from our cost guides: the delivery-and-set lines above are exactly the items a stick build never pays and a modular budget must; and they are also the items that stop growing once your plot is within a sensible radius of the factory or port.
