A procurement comparison is only useful when the scope is comparable
A lower headline price may simply exclude delivery, crane work, emergency-egress works, installation, utility connections, testing or documentation. ShelterMetric therefore treats scope definition as part of cost comparison rather than as a separate administrative exercise.
Use public procurement cases as scope evidence, not as a price list
The same word “shelter” can appear in a capital construction project, a multi-lot PMU supply tender or a repair of an existing basement. Those published amounts answer different questions. Open the case studies before using a public number as a benchmark.
Recommended sequence
Freeze the project inputs
Facility, capacity, site, shelter requirement and the intended procurement outcome should be defined before suppliers are asked to price the project.
Separate supply from full implementation
A structure-only offer is not comparable with a package that includes design, egress, logistics, crane work, earthworks, engineering systems, installation and commissioning.
Compare like-for-like supplier scopes
Transport, crane mobilisation, emergency-egress scope, installation, commissioning, documentation and warranty should be visible as separate or clearly included cost groups.
Define documents and acceptance before award
Required product evidence, commissioning records, handover documents, defect handling and warranty should be visible before the procurement is completed.
Acquisition price and ownership cost answer different questions
Supplier selection may focus on acquisition scope, but some owners also need to understand annual maintenance and longer-term ownership cost. Keep those lifecycle scenarios separate from the tender price so they do not distort the procurement comparison.
