Define goals, property conditions, project priorities, rough scope and the decisions needed before design advances.
The exact path varies by property and scope, but the operating principle stays consistent: decisions should move forward in the order that reduces ambiguity for the next phase.
Define goals, property conditions, project priorities, rough scope and the decisions needed before design advances.
Develop the space, layout and architectural direction around how the property should function and feel.
Coordinate the structural and technical requirements that support the design and permit path.
Prepare submittals, respond to review, coordinate selections, trade inputs, procurement and site logistics.
Manage field execution, communication, sequencing and quality control against the approved project scope.
Resolve completion items, document handoff information and make the final project review clear.
Preconstruction is where plans, engineering, selections, trade inputs, permits, procurement and site logistics are translated into an executable sequence. It is not dead time between design and construction.
For major residential work, JBC uses this phase to clarify ownership, surface constraints and reduce the number of decisions that construction has to make under pressure.
