A useful RFQ lets suppliers quote the same construction and scope. Use this checklist with your approved project specification; it is not a design certificate or test report.


Material and construction schedule


Electrode type: GI tube, electrolytic copper tube, solid copper or copper-bonded steel.

Model, diameter, length, wall thickness or copper-coating thickness, terminal and coupling details.

Electrode, backfill, conductor, chamber and connection accessory quantities.

Required model-specific datasheets, material declarations and relevant test reports.


Scope and site information


Project address, layout, panel/equipment schedule and conductor routes.

Soil-resistivity data, existing pit test records and approved acceptance criteria.

Supply-only or installation scope; trenching, reinstatement, access and unloading responsibilities.

Separate prices for material, freight, civil work, installation and testing.

Delivery or execution date, inspection requirements and quotation exclusions.


Handover documents

Specify as-built locations, pit identification, test-link details, measured results, test method, instrument identification and maintenance requirements in the agreed scope.
