- Highest potential for maximum value, team collaboration, value-engineering, efficiency, fast-track timeline, transparency, and positive owner experience.
- Up to 30% reduction (2) in opportunity costs and project timeline due to partially-concurrent building and design schedules.
- Reduces probability of +10% cost variance between up-front, bids in the “low bid process”, and the eventual cost (2).
- No assumptions on design and pricing; all details are fully and clearly communicated prior to construction; limits unknowns.
How: Selection criteria: character, competence, expertise, relationship, referral, and ingenuity.
What: Builder and architect selected prior to design.
- Attempt to get best possible pricing.
- Partial design definition causes GC’s to make assumptions on design details, scope, and owner vision.
- Medium risk of project cost overruns (1.6% cost growth)(1) and opportunity costs with time consuming RFQ/RFP process.
- Caps potential for collaboration, value-engineering input, and real-time budgeting.
How: Selection criteria: composite score between the RFP and bid (off of current design definition: between 10% - 50%).
What: Builder selected after design is partially completed.
COST ONLY APPROACH
- Perceived as fastest way to achieve lowest-cost product.
- “Low Bid” price rarely matches eventual project cost. Highest risk of cost overruns (9% total cost growth) (1).
- Highest opportunity costs due to sequential – not concurrent – schedule (14% schedule growth in high complexity projects) (1).
- Strained or no relationship with construction team.
- Little to no value-engineering input.
- No GC budgeting input during design phase.
How: Selection criteria: lowest “responsible” bid; period.
What: Builder selected after design is completed.
EARLY QUESTIONS TO CONSIDER
- Is the builder selected before, during, or after building-design?
- What is my realistic time-frame; is this a fast-track project?
- Do I want real-time budgeting during the design phase?
- Who will lead & manage my project: owner, architect or builder?
- How do I know everything is included in a proposal or bid?
- Will aggressive sub-contractor bidding occur?
