Why the Need for Speed?
![Page 4: Speed to Market - District Energy](https://reader034.vdocuments.mx/reader034/viewer/2022042318/625cd88059956554b77079a7/html5/thumbnails/4.jpg)
• Seasonal Business – Need to meet peak demands
– Winter (heating demand) and Summer (cooling demand) come every year
– Shortening a project by a few months can add a year of “service”
• Not Enough Implementation Time – Equipment failure
– New customer needs load quickly
– Delayed decision to execute the project
• Minimize Plant Disruption
• It’s Fun to Go Fast
Why the Need for Speed?

• How Do I Do It? – Specification developed for long-lead items
– Owner reviews bids and places equipment order
– Shop drawings for equipment come to owner
– Delivery of equipment can be to Owner or Contractor
• What is Different? – Can drastically reduce schedule
– Provides early detailed equipment information
– Adds to the contracts to administer
– Owner is responsible for coordination between contracts
• Scope
• Delivery
• Warranty
Early Equipment Procurement

• Two major types: – Construction Manager Agent
– Construction Manager at Risk
• Procured via:
– Request for Qualifications (RFQ)
– Request for Proposal (RFP)
– Other method
• Responses can include:
– Construction fee
– Pre-construction services
– General conditions
– Staffing plan
– Schedule
– Change order markup fee

Enwave - Biomedical District Steam Plant Design-Build
![Page 18: Speed to Market - District Energy](https://reader034.vdocuments.mx/reader034/viewer/2022042318/625cd88059956554b77079a7/html5/thumbnails/18.jpg)
• Process – Originally Design-Bid-Build
– Converted to D-B near the end of design
– D-B-B schedule and D-B project schedule are nearly identical
• Lessons Learned – Earlier conversion to design-build
decreases construction schedule
– D-B contract has allowed for incorporation of changes during construction w/o modifying the schedule

• There are Many Reasons a Project is Accelerated
• Three Methods to Accelerate – Early equipment procurement
– Construction manager
– Design-Build
• All options have pros/cons
• Design-build is the fastest
• The right solution is different for every project
Summary
Other Options: – Phased Construction Contracts
– Commissioning Agents
– Permitting Agent (expediter)
