Price the preliminaries and general conditions
Price the cost of running the job itself - site staff, welfare, plant, scaffolding and insurances - split into time-related and fixed and driven by the programme, then carry it into the bill.
Comment ça marche, étape par étape
4 étapes à travers la plateforme - ce que vous faites à chacune et pourquoi c’est important.
List the prelims scope
Frais de chantierBuild the list of everything it takes to run the site: management and supervision, welfare and cabins, temporary services, common plant, scaffolding, security, insurances and bonds.
Pourquoi: The items you forget in prelims are the ones you fund out of profit. A complete checklist read against the contract is the difference between a covered site and a leaking one.
Split time-related from fixed
Frais de chantierMark each item as time-related or fixed, then price the time-related ones per week against the programme duration and the fixed ones as one-off set-up and removal.
Pourquoi: Splitting them this way is what lets prelims flex if the programme moves. If the job runs four weeks late, you can show exactly what the extra time costs instead of guessing.
Check the resources roll up
Synthèse des ressourcesLook at the staff, plant and cabins the prelims imply in the resource summary and sanity check the headcount curve against the programme peaks.
Pourquoi: A prelims price that needs three site managers in a quiet month is a warning. Seeing the resource curve catches a double count or a gap before it reaches the tender total.
Carry it into the bill
Devis quantitatifBring the prelims total into the bill as its own section, kept separate from measured work, and read it back as a percentage of the works value.
Pourquoi: Keeping prelims visible as their own line lets a reviewer benchmark them at a glance. Burying them in the rates hides the one number a client always wants to test.
