Design & Build benefits
Benefits of our Design & Build solution
The client manages one contract with the Design & Build team leader, who collaborates with the end-to-end team of stakeholders until completion.
Client
1 contract
Team leader
- Design
- Procurement
- Construction
With the Promexa team involved from the start of the design process, components of the project – such as site preparation and foundation work – can take place while detailed designs are being completed.
Day 1
- Detailed design
- Work preparation
- Early construction start
Because the project is more efficient, and construction can start before the final designs are completed, owners can occupy their facilities and start production sooner.
