Alternatives Guide
CivicBridge Sourcing guide to alternative formats and quote scopes
This guide helps buyers compare building formats and quotation boundaries. CivicBridge Sourcing is an independent service. It is not a manufacturer or authorized dealer. It is not smartspace and is not affiliated with smartspace. Original-brand supply is outside this service.
Send Project Requirements- Use and occupancy
- Module dimensions or clear span
- Wind, snow and seismic criteria
- Project jurisdiction
- Quantity and unit basis
- Destination and quote boundary
Three tables for one decision
| Choice | What to write | What can go wrong |
|---|---|---|
| Volumetric modular construction | Closed size, weight, and road limits | The unit fits the program and misses the bridge or gate |
| Panelized construction | Panel count, site crew, and weather window | A low package price ignores days of open structure |
| Foldable or expandable | Folded transport size and opened floor size | Only one of the two sizes is priced |
| Light-gauge or rigid frame | Cold-formed steel or hot-rolled members, clear span, eave height | Member suitability is assumed without project calculations |
| Input | Buyer action | Do not assume |
|---|---|---|
| Wind speed and exposure | Give the figure or say it is unknown | A generic map value is the project value |
| Ground snow load | Request the site ground snow load; the engineer determines the roof design snow load from project conditions | A southern example fits a mountain site |
| Seismic design category | Name the category when the engineer has it | The factory will invent the category |
| Floor live load | Separate office load from storage or crane load | One number covers every room |
| Label | Usually inside | Often outside |
|---|---|---|
| Shell | Primary frame and a basic envelope | Foundation, interiors, permits |
| Delivered | Transport to a named point | Unload crew and crane |
| Installed | Set and weather-in, if the crew is named | Utilities and local inspections |
| Turnkey | A wider coordination list | Anything not written, including soils and fees |
A repeatable standard layout is fair to compare when the site accepts published module dimensions. A custom bay spacing or foundation interface needs engineering time in the schedule. Neither choice is automatically the cheaper path, and this guide does not publish a percentage difference.
Documents to request, not files hosted here
Drawings and calculations
- Plans, elevations, and member sizes for the quoted system
- Design criteria sheet listing wind, snow, and seismic inputs
- Foundation interface reactions, even if the foundation is by others
Materials and envelope
- Steel grade, coating, purlin and girt spacing
- Insulated metal panel or sheet assembly with thermal transmittance
- Fire-resistance rating only if a tested assembly is identified
Commercial and logistics
- Quantity, destination, and incoterm or delivery point
- What is excluded from installation and permits
- Warranty text tied to the quoted manufacturer, not to this website
There is no downloadable certificate pack on this site. Ask the supplier for the sheets, then compare them with the brief. AISC 360 or AWS D1.1 may be relevant to a steel system; ISO 9001 may describe a plant system. Relevance is not the same as a current certificate for your order.
Questions to close before you accept an alternative
Format
Is a volumetric box required, or will panels meet the program?
Choose from access, finish level, and how much work can happen off site. Write the reason so a later substitution is visible.
Are folded and opened sizes both known?
If only one size is known, mark the other as open. Do not let a supplier price the smaller state and deliver the larger one.
Evidence
Which document belongs to this system?
Match the drawing number, plant, and jurisdiction. A general standard named on a homepage does not travel with the shipment by itself.
What remains the buyer decision?
Code path, acceptance of a deviation, and the contract. The sourcing desk can list the open items. It cannot close them for you.
See the formats available as inquiry options or send the open choices.

Tell us which rows are decided and which rows are still open. Factories can quote the decided rows and flag the rest.
