3Brief Overview of Alternative Project Delivery
Options
- Is there an ideal delivery method?
4Key Points Delivery Options
- Within 1886, there are multiple forms of
allowable alternative delivery formats - Each form has strengths and weaknesses
- Pick the best approach for individual project
needs

Construction Management at Risk (CM_at_Risk)
Lump SumDesign-Build (LS)
ProgressiveDesign-Build (GMP)
Design-Build- Operate/Finance, etc.
Design-Bid-Build(DBB)
6Traditional Design-Bid Build Delivery
Construction Management at Risk (CM_at_Risk)
- Defined, proven process
- Distinct milestones to ensure expected results
- Manages to known challenges (unknowns change
orders) - Traditional cast of participants
- But does not always meet Owners needs for
collaboration, innovation, and accountability

- Design-Build Lite
- Promotes early collaboration between designer and
constructor - Allows selection of a Contractor based on
qualifications and fee (but not a full bid) - But still relies on separate contracts,
resulting in a forced marriage

ProgressiveDesign-Build (GMP)
- Key Advantages
- Investment in Projects, not Procurements
- Schedule
- Progressive estimates address Owners challenges
- Better opportunities for local consultant support
10Progressive Design-Build Procurement Model
- Progressive model complies with 1886 as long as
some form of price/cost-related criteria is
included in selection - Offers owners maximum flexibility/opportunity to
collaborate on permitting/design - Owners have an off-ramp in case of permitting
issues or if GMP cant be negotiated - Very successful evolving model

11Invest in the Project, not the Procurement
- Progressive Design-Build reduces the complexity
and cost of the procurement process - Owners staff time and additional technical
support for procurement - Stipends for multiple unsuccessful proposers
- Industry investment in design for proposal
- Additional risk included in ultimate project cost
(more unknowns higher contingency)
LC
12Shorten the Procurement Schedule
- Progressive Design-Build reduces the time it
takes to select a Design-Builder - Timing can procurement process start before all
basis of permits are certain? - Duration does proposal period need to allow time
for design/detailed pricing? - Potential for delay how many issues/technical
questions might arise?

15Progressive Estimates Address Owners Challanges
Construction estimating can start very early in
design, allowing comparison of specific technical
solutions.
Progressive estimates keep Owners informed and
support informed scope adjustment decisions.

Level of Design Completion
First fully detailed estimate can be used to
establish a scope baseline. Estimating process
is open book.
Owners can use third-parties to verify
cost...and go to the hard-bid market if needed
(the off-ramp).
Guaranteed Maximum Price established at the right
time risk and contingency reduced, schedule
needs met.
16Progressive Design-Build Supports Smaller Firms
- Selection methodology focuses on traditional
evaluation criteria - Primarily qualifications based
- Selection criteria can be tailored to support
local expertise/capabilities - Proposal preparation significantly less costly
- Limited design effort to be performed on spec
- Smaller firms can support larger teams with
minimal proposal investment - More flexibility to use subconsultants after
design-builder selection - Owner can provide input on preferred specialty
firms - Design packages can be developed after the
procurement - Does not require as much at-risk capability
- Subconsultants can participate without taking an
at-risk position
