DBIA Test
a subjective measure for evaluating a project that is hard to measure; this is determined through the
design process, not after the project is completed - design value
describes in terms of exactly how the product and/or its components must be built; cookbook approach;
developed by the design builder but used by owners in the RFP/bridging documents for operability or
maintenance needs and conditions of permits or third parties; examples: uniformat C10, partitions.
"Install gypsum wallboard on 3-5/8" metal studs at 16" on center with XX acoustical insulation per YY
standards." - prescriptive requirement
how team members are paid (fp, gmp, cost reimbursement, target price, unit price) - contracting
approach
linear, sequential process, A/E selected on qualifications, GC selected on low price, design is fully
completed without input from GC, A/E acting in owner's interests, with a historically strong bond,
process is well-established and understood - Design-Bid-Build (DBB)
similar org structure to DBB, construction manager selected by QBS or best value, contractor provides
precon services, negotiated gmp contracting approach, open book estimating process, potential to fast
track project, construction cost determined before design completed, potential issues over what is
reasonably inferable from gmp design documents - construction manager at risk
The owner contracts with one entity (a person or firm) to provide both design and construction services,
designer and contractor have a direct contractual relationship, selected by QBS or best value, wide
spectrum of contracting approaches and organizational structures, single point responsibility, owner
does not manage designer, owner exposure to claims is significantly reduced - Design-Build
how team members are selected (QBS, best value, low price, sole source) - Procurement Method
similar to design build, in industrial and power generation sectors, systems and performance testing are
central to scope, contractor will typically perform engineering with its in-house staff, owner has need for
single point responsibility, contracts include plant and process performance guarantees, contract items
, include performance and schedule liquidated damages and limitations of liability - engineer
procure construct (epc)
owner contracts with multiple trade contractors, attributes are typically similar to dbb, owner's ability to
schedule and coordinate the work - Multiple Prime Contracting
multi-party agreement - all parties equal, QBS procurement and target pricing contract approach, private
sector use (limited at this time), key: owner's ability to accept risk - Integrated Project Delivery
(IPD)
Instead of government building and maintaining major infrastructure (such as highway, water treatment
plant), build and maintenance is outsourced to a private company. Opposed by public sector unions. this
is not considered a delivery system but its underlying approaches are delivery systems and typically use
DB. multiple procurement and contracting approaches - public-private partnership (p3)
intense efforts to establish scope early in the process; drives early team formation to include key trade
subcontractors; can enable big decisions to be made early, affect project outcomes at lowest cost,
establish a need for co-location and collaboration, and compress time during concurrent design and
construction - shift left
typically two-phase best value procurement with lump sum contract; owner defines project
requirements and scope of prescriptive work; use of performance-based technical requirements with
limited prescriptive specifications - traditional design build
design and price are progressively developed after the design-builder is under contract; final project cost
and schedule commitment is not established as part of the selection process; two phases: preliminary
services and final design and construction services - progressive design build
describe the end result - criteria documents
prescribes how to achieve the end result - bridging documents
