Start with the decision
Build the plumbing schedule around confirmed dependencies rather than a promised duration in isolation. The important inputs include fixture selection, access to connection points and agreed service-interruption windows. Ask the contractor to state what must be ready before it can begin and what the following trade will receive.
This guide is for business-to-business project planning in the United States and Canada. For the wider trade context, visit the plumbing resource hub.
Plan the handoffs
| Package | Information needed before release | Completion handoff |
|---|---|---|
| Fixtures | fixture schedule, quantities and supply responsibility | fixture information and agreed operating documentation |
| Distribution piping | system boundaries and approved routing information | agreed testing and inspection records |
| Tie-ins | identified connection points and operating constraints | tie-in records and updated identification information |

Fill in the response, owner or source, and date checked. Keep unresolved items visible. The file contains planning prompts only; it does not calculate quantities or make an approval decision.
Put the checklist to work
- Separate approvals, procurement, mobilization, installation and completion checks. Assign an owner to each release decision.
- Ask for the contractor’s stated availability and the date it was confirmed. Do not present an indicative window as a reserved crew.
- Resolve interfaces involving excavation, coring, firestopping, equipment supply and restoration of walls or ceilings. Put decisions and deliveries that affect the sequence into the same schedule discussion.
- Agree how changes will be raised. Record the affected activity, revised assumption and who confirms the next workable date.
A scope gap worth discussing
Illustrative example — not a Build Accord client project
A washroom quotation assumes existing connection points can be reused. The site visit identifies a different layout. Reconcile the revised routes before comparing the price with another proposal.
Apply this to your decision: A dependency-based schedule discussion with named owners and confirmation dates, without invented standard durations or guaranteed delivery windows.
Using this in the US and Canada
For a project in the United States
Record the state, local jurisdiction and actual service area. Confirm the project location and the scope of the business’s authority with the responsible project team. The U.S. Small Business Administration provides a starting point for business licensing resources.
For a project in Canada
Record the province or territory, municipality and actual service area. Use Canada’s permits and licences resources to locate relevant checks, including the linked BizPaL service. Confirm requirements for the actual activity and location.
For either market, state the currency, units and deadline time zone. This worksheet is general planning guidance, not a determination of licensing, procurement eligibility or technical compliance.
The next useful step
Continue with plumbing contractor handover checklist. For the other side of the conversation, see the plumbing bid proposal guide.
Build Accord coordinates introductions between construction project teams and trade contractors. An inquiry starts a discussion of fit and availability; it does not guarantee a contractor, an invitation to bid or an award. These guides are not a listing of currently available crews or projects.
