Field notes / procurement decisions
Specification questions, quote scope and purchase-document checks for membrane buyers.
A procurement manager's notes on direct-from-manufacturer waterproofing membrane sourcing: how much actually lands in the budget after freight, spec mismatches and site waste, why PVC specification handoff decides the outcome, and which categories are cheaper to buy locally.

Read field note →A field note helps identify which details belong on a request. It is not a statement that a catalog item meets your project specification. A membrane can share a generic product name with another construction while differing in reinforcement, carrier film, backing, thickness tolerance or application conditions. Ask the proposed supplier to name the offered product and document revision.
Keep the application visible when you compare options. An exposed membrane, a buried foundation system and a liquid-applied coating have different interfaces to resolve. Procurement questions should name those interfaces and the party responsible for reviewing them. Do not turn an illustrative specification value into a universal acceptance requirement.
Commercial comparisons also need their assumptions. Currency and quantity units should sit beside the price; freight, accessory supply and destination costs need separate confirmation. A provisional target budget can guide a discussion, but it does not confirm that a supplier can meet the scope or the requested timing.
When a document is received, match its product name and construction to the actual offer. Check whether the test or certificate scope covers that material, rather than treating a company-level statement as evidence for every membrane. Questions left open should remain visible in the buyer’s record until resolved.
