PROJECT DELIVERY METHODS 



3

Design-Bid-Build 
Historic public contracting method 
Owner supervises design by Architect-Engineer (A-E) 
Advertisement of contract, plans, specs 
Award to lowest price responsive bid submitted by a
responsible bidder 
General contractor assembles subcontractors 
Multiple procurements: design then construction 
No constructor participation during design 
Owner bears most design error/omission risk 
4

General Contractor/Construction Manager 
Owner controls design by A-E 
Constructor selected as a consultant during design
phase based on qualifications and price factors 
Early constructor involvement for
constructability/value engineering - lowers design risk 
Maximum construction price negotiated late in design
phase 
Sub-contracts bid competitively, except mechanical
and electrical principals 
Constructor shares in the cost risk. 
5

Lump-Sum Design/Build 
One major procurement for design-construct team 
Potential to fast-track (overlap design and construction) 
Constructor incentive for optimizing design and
construction. 
RFP containing preliminary design, performance specs,
evaluation criteria 
Best-value selection with lump sum price 
Best if owner can define project in performance terms and
relinquish control 
Scope changes may be more costly 
6

Price-Factors Design/Build 
Added to RCW 39.10 in 2013 
Similar to fixed-bid D/B except for selection method
and price determination 
D/B team selected by RFP based on qualifications and
price factors (such as profit/overhead rates and general
conditions work) 
Fixed price established by negotiation late in design
phase 
Potentially less price risk for builder, more design
control for owner
