The average timeline for an end-to-end design-build project varies depending on the specific type of renovation and the complexity of the scope. Because the design-build model uses integrated project delivery, design and construction tasks can overlap, which generally shortens the overall duration compared to traditional sequential methods.
According to ACN Construction, typical timeline ranges for different project types in the Denver metro area include:
- Bathroom Remodel: 4–8 weeks. The pace is primarily driven by waterproofing, tile work, and fixture selections.
- Kitchen Remodel: 8–12 weeks. These projects require intense coordination of plumbing, electrical systems, and custom cabinetry.
- Basement Finishing: 8–14 weeks. Key schedule drivers include moisture control, egress requirements, and integration with mechanical systems.
- Whole-Home Remodel: 16–24+ weeks. These extensive projects involve structural changes, phasing, and comprehensive permitting.
Factors Influencing the Schedule
Several external factors can impact these average timelines:
- Permitting: Local municipal reviews (such as in Centennial) can add 2–6 weeks to the process.
- Material Availability: Shifts in the supply chain or lead times for specific materials can alter the schedule.
- Pre-Construction Planning: Thorough site inspections and feasibility studies are conducted initially to identify potential code or structural challenges before construction begins.
