Connect the drawings to the construction scope

For an Azusa build or remodel, confirm which drawings and revisions the proposal is based on. Record any design items still pending and the assumptions used for pricing. That reference makes later conversations about changes more precise and helps the owner and construction team work from the same information.

Identify the drawing set used for pricing

Record the drawing dates and revisions that support a proposal. Keep later changes separate until their effect on scope, materials, and related trades has been reviewed. This helps everyone distinguish a pricing assumption from a detail that has already been included in the construction plan.

Discuss your Azusa project

Send the current Azusa drawings and any revisions or questions that remain open. If design is still underway, tell us which parts of the project are ready for a scope discussion.

Tell us about your project
