Fast-track construction

Content sourced from Wikipedia, licensed under CC BY-SA 3.0.

Fast-track construction is a method that starts building before the full design is finished to save time. Owners want shorter schedules to bring products to market faster, reduce overcrowding in schools, provide homes sooner, or lower financing and overhead costs. It can also help limit inflation’s impact on the project.

How it works
- Design and construction activities overlap, so parts of the work begin before the design is complete.
- Because plans are incomplete, the final cost is uncertain. Contracts often use cost-reimbursable arrangements or a guaranteed maximum price (GMP), but scope can still be unclear.
- Changes late in the process (like a different building shape after foundations are laid or late equipment choices) can raise costs and cause delays.
- A higher level of coordination, planning, and experienced management is essential.

Delivery methods and how fast-track fits
- Fast-track can be used with many delivery methods, including CM at Risk, Agency CM, design–build, bridging, and integrated project delivery.
- It can also be used within traditional design–bid–build by bidding separate contracts for different phases.
- About 40% of building projects are said to use fast-track in some form.

Pros and cons
- Pros: significantly shorter project timelines, earlier occupancy or market delivery, and potential financial savings.
- Cons: more complex management, higher risk of cost overruns if design changes occur, and potential disputes over scope and guarantees.

Origins and evolution
- Historically, public projects used sequential design–bid–build with lump-sum bids, which didn’t suit fast-track.
- In the 1960s, public institutions explored fast-track to speed up campus construction. A construction manager (CM) was hired to oversee phased design and overlap bids with ongoing design work.
- The CM could act as an agent (Agency CM) or take on contracts and guarantees (CM at Risk), shaping how costs and schedules were controlled.
- Today, fast-track is a common term in the U.S. construction industry and is supported by multiple project delivery methods.
