Design Approach
Project team created a Project Definition Document (PDD)
PDD allows for early identification of challenges and scope gaps
PDD allows for Airport wide review and input of the project scope
Airport Directors have reviewed PDD and signed off on final scope of work
Design to Budget not to Scope
Designer will be required to have experience designing to budget
Project scope will be adjusted to fit budget rather than budget being adjusted to
fit scope
Designer selection will include a process for design teams to bring their
ideas to solve key C1 Building design challenges

Environmental
Sustainability Plan
The C1 Building Expansion was the first project to go through the
Sustainable Project Assessment and Review Committee (SPARC)
C1 has been identified as a Tier 3 project.
Project team will present to the Commission Sustainability
Committee at 30% design to review sustainability options
Project team will be requesting Commission input on sustainability options
Project team will be reviewing project cost impacts associated with the
options

Project Delivery
The project will be delivered with a General Contractor,
Construction Manager (GCCM)
Procurement will follow RCW 39.10
Port of Seattle is certified by Capital Project Advisory Review Board
(CPARB) to utilize state approved alternative contracting procedures
The project team believes thatonce the GCCM has been procured, it
will be likely that all parties will recommend and agree to the use of
an Electrical Contractor, Construction Manager (ECCM) and a
Mechanical Contractor, Construction Manager (MCCM)

7

Project Delivery
GCCM will be procured concurrently with project designer
Their initial role will be for pre-construction services (as-building, constructability reviews,
estimating and scheduling)
Benefits of a GCCM Delivery
Early involvement and input from the contractor
Contractor insight and assistance with complex phasing
Contractor to provide cost estimates at major design milestones to ensure that
project is being designed to budget
Early schedule assessment
If ECCM and MCCM are used the Electrical and Mechanical contractors will be
procured based on qualifications and not low bid
