Independent alternative sourcing

Boxx modular alternatives for factory quote comparison

HarborField Sourcing is an independent sourcing service. It is not boxx modular, does not claim authorized dealer status, and is not affiliated with boxx modular. The desk helps a business buyer compare alternative buildings. It does not claim to supply the original brand.

A boxx modular search is the starting point for a brief, not a commitment to supply that brand. Write the use, the module dimensions, the design loads, the jurisdiction, the quantity, and the destination before any factory is asked for a number. A workable example is six modules, each 12 ft by 40 ft, with a 14 ft eave, when those are the buyer figures.

Six checks before a factory number is useful

These checks belong to the buyer brief. They are not a claim that HarborField Sourcing designs, fabricates, or approves the building.

Product form

Say whether the comparison is volumetric modular construction, a panelized pack, a folding unit, or a portable building that will be relocated.

Primary frame

Ask each supplier to name the primary frame, secondary framing, purlin and girt layout, and whether the proposal uses built-up plate, hot-rolled steel or cold-formed steel.

Envelope

Record cladding, roof, openings, insulated metal panel if that is the proposal, and the thermal transmittance or R-value the quote assumes.

Scope tag

Tag the quotation as shell, delivered, installed, or turnkey. A lower line that omits foundation work is not the same purchase as a set building.

Site interface

Note the foundation interface, crane lift plan, utility rough-in, and which party pulls permits for the project jurisdiction.

Document pack

Request drawings, calculations, and the weld or coating notes that apply to the quoted system. A brochure badge is not project approval.

Send the brief before comparing prices

HarborField Sourcing will organize factory quotations for the same specification, quantity, destination, and scope. No percentage off a market price is stated here, because this desk does not hold a same-scope quote file for your project yet.
