Prison Fence Procurement: Verify the Offered Assembly

For custodial fence procurement, the released project specification must define the required assembly and evidence. We recommend reviewing product identity, permitted configuration and acceptance authority before any custom fabrication is approved. A 358 mesh designation or prison-grade description cannot establish that the offered panels, gates and connections meet the project’s requirements.

Establish the authorised requirement

Record the project specification, revision, acceptance authority and controlled document route. Use only information released for the procurement. Site operating details, sensitive layouts and security procedures belong in the client's protected systems, not in public supplier material.

Confirm whether the order concerns a complete perimeter system, an internal enclosure, gates or replacement components. Each scope needs its own acceptance basis. Approval of one product for one location should not be presented as general approval for custodial work.

Match evidence to the physical assembly

Evidence field Check against the offer
Product identity Exact model and manufacturer
Configuration Height range, posts, panels, fixings and installation limits
Gate arrangement Leaf, frame, hardware and permitted opening configuration
Document standing Issuer, reference, revision and current listing where applicable

Where LPCB certification is specified, check the relevant Red Book Live listing rather than relying on a logo in a brochure. A material test or management-system certificate serves a different purpose from a system resistance classification.

Gate leaves, frames, posts and hardware need evidence for their exact configuration; a photograph alone proves no rating.

Do not add security claims to an ordinary specification

Keep mesh geometry, construction choices and documented resistance claims in separate fields. A second skin, heavier wire or changed frame may be a manufacturing option, but its effect on the accepted system must be reviewed against the relevant evidence. Ask the supplier to identify the exact configuration covered rather than extending a certificate to an unassessed custom variant.

A 358 opening describes mesh geometry. Double skins describe construction. Neither statement alone establishes a resistance rating, anti-escape performance or project acceptance. Any claim must come from evidence covering the supplied assembly and its installation conditions.

The public LPS 1175 standard also has defined exclusions. It should not be expanded into a promise about every possible threat or about an entire site.

Use a discrepancy register before commercial award

Suppose a submission contains 24 required evidence items. Twenty are matched, three need clarification and one is absent. The register should show 20 matched, three open and one missing; reporting it only as “83% complete” can hide the significance of the missing item.

This is an illustrative document count, not an acceptance score. A single missing critical item can prevent acceptance even when almost every other attachment is present. Assign each open item to an owner and obtain the authorised decision before manufacture or substitution.

Keep acceptance and maintenance connected

Retain the accepted component and hardware references with the inspection and maintenance package. If a replacement part differs in material, geometry or connection, return that change through the authorised review route before manufacture. FencingWise enquiries should include the released product schedule and evidence list, allowing supply scope and unresolved requirements to be stated without implying a general custodial approval.

FencingWise enquiries for such projects should carry the released product schedule and required evidence list. We do not infer a custodial approval from a product family name. Read LPS 1175 ratings and certificate scope checks before evaluating a rated offer.
