Design Bid Build Design Build
Construction
Management at Risk
Owner Participation
Involved in all phases of
project
Involved in preliminary

phases
Involved in all phases of
project
Contractor Scope of Work Construction phase
Design, pre-construction
services & construction
Engaged as early in the
project as possible to guide
and assist the owner
through all phases of project

8. ADVANTAGES & DISADVANTAGES - DBB
8
Advantages
Easy implementation, well understood, and has
clearly defined roles for the parties involved
Simpler process to manage
Owner controls overall design
Lower bid, maximum competition
Known project cost before construction
Disadvantages
x Owner at risk to contractor for design errors –
generally higher risk of change orders and claims
x Typically longer schedules
x No contractor input in design, planning or value
engineering (VE)
x Can promote adversarial relationships
9. ADVANTAGES & DISADVANTAGES - DB
9
Advantages
Single entity responsible for design and
construction
Reduction in overall project duration
Cost efficiencies can be achieved
Change orders typically only arise from owner
changes
Disadvantages
x Less design control and involvement by the
owner
x Owner pushed for early response in order to take
advantage of the speed of DB
x Owner does not receive the benefits of the
checks and balances that exist when it contracts
separately with a designer and a general
contractor
x May not be suitable if owner is looking for an
unusual or iconic design
10. ADVANTAGES & DISADVANTAGES - CMAR
10
Advantages
Opportunity of transfer of responsibility and
some risk from owner to CM
Owner gains benefit of having the opportunity to
incorporate a contractor’s perspective and input
to planning and design decisions
Ability to“fast-track”early components of
construction prior to completion of design
Opportunity for owner to participate in
subcontractor selection
Disadvantages
x Can have a tendency for higher costs due to
focus on quality and potential for CM to leverage
pricing advantage
x During construction phase less assistance given
as CM is at risk during construction phase, i.e.
revert back to GC tendencies
x Difficult for owner to evaluate the GMP or
whether the best price has been achieved for the
work
x Requires a high level of communication between
owner and the CMAR
11. 3. WHEN TO USE
EACH METHOD
Discussion of the types of projects best suited to each method.
12. WHEN TO USE – MAIN FACTORS TO CONSIDER
12
1. Project size and complexity
2. Legislative/regulatory requirements
3. Risk tolerance
4. Schedule sensitivity
5. Local market knowledge
6. Desired level of owner influence and control
7. Owner’s resources and capabilities
13. WHEN TO USE – IN A NUTSHELL
13
DBB
Project
o Small to mid-size
o Ordinary; low complexity
o Low schedule sensitivity
Owner
o Desire for lowest competitive bid
and willing to accept the
transactional/ adversarial
relationships that often result
o Less experience amongst PM team
DB
Project
o Medium to large-size
o Low to moderate complexity;
prototypical or repetitive in nature
o Schedule more important than cost
Owner
o Willing to cede control of design in
exchange for early cost guarantees
and lower risk
o Prefers a single point of
responsibility
o Experienced PM team
CMAR
Project
o Large-size
o Uncertain; high complexity
o Schedule and quality more
important than cost
Owner
o Higher risk tolerance
o Emphasizes relationships and willing
to negotiate costs vs. solicit lowest
bids
o Desire for open book accounting
and willing to dedicate the added
effort required to manage it
o Experienced PM team
14. PEOPLES GAS
System Modernization Program (SMP)
14
EXAMPLE PROJECT - DBB
Replacing over 2,000 miles of natural gas
main within Chicago
$8B construction cost
Why well-suited for DBB:
Repetitive work
Ample time to complete engineering in
advance of planned construction
Desire for competitive pricing
15. MONADNOCK HALL
Southern New Hampshire University
15
EXAMPLE PROJECT - DB
300-bed dormitory
100,000 square feet
$34M total cost
19 month duration
Why well-suited for DB:
Tight timeline
Viewed as a typical project
Owner was able to retain some involvement
in design through design progress meetings
and submittals
16. UNIVERSITY OF CHICAGO
Center for Care and Discovery
16
EXAMPLE PROJECT - CMAR
State-of-the-art facilities for advanced surgery,
cancer, interventional radiology and
gastroenterology, neuroscience, and high-tech
imaging
1.1M square feet
$700M construction cost
Why well-suited for CMAR:
Very large project
High complexity
Commitment to quality
Schedule-driven
Organization with sustained capital portfolio that
is able to develop repeat vendor relationships

18. 4. BEST PRACTICES IN
USING EACH METHOD
Tips on how to manage under each method on a day-to-day
basis
19. SELECTED DBB BEST PRACTICES
19
1. Seek mid-design estimate, schedule, and constructability reviews
Most projects benefit from some level of constructor involvement in the preconstruction phase
2. Ensure sufficient design completion prior to bid phase
Some have noted an increasing trend of construction documents issued with less definition than has been historically expected
Lack of design definition causes a risk of costly changes in construction
3. Incorporate best value vs. lowest cost selection criteria in the procurement process
A best value approach allows a blended cost/qualifications-based selection that can help to mitigate the transactional nature of DBB
4. Implement robust change and claims management practices
DBB has been found to carry the highest risk of changes and claims
20. SELECTED DB BEST PRACTICES
20
1. Invest sufficient effort to define the project during preliminary design
Early involvement by key stakeholders is necessary
Uncertain/undefined areas allocated cost through allowances require extra diligence because owner retains cost risk
2. Require that the contractor and designer have prior experience together
And together have a successful track record of similar DB projects
3. Require the contractor to implement a robust trending system
The system identifies, evaluates, and communicates potential changes proactively to avoid budget and schedule impacts
4. Make sure the owner is set up to make timely decisions early
In order to avoid owner-driven schedule delays due to DB fast-tracking
21. SELECTED CMAR BEST PRACTICES
21
1. Hire the CM early
No later than 30% design
2. Select the CM with emphasis on a relationship of trust and confidence
Proposing CM’s have a preexisting relationship or are interested in a long-term relationship
Make selection additionally based on qualifications, prior CMaR experience, fee proposal for preconstruction and GC’s, and opinion of
probable costs
3. Execute the GMP at the right time given project and owner priorities
Too early can shift too much risk and control from owner to CM
Too late prolongs cost certainty, but can be advantageous provided the PM team is sophisticated enough to actively manage the risk
4. Both owner and CM implement robust project controls
Resources dedicated on both sides to managing the open book accounting
Value engineering is performed at 30 percent design
Cost trending is performed throughout design to anticipate cost growth and avoid costly redesign efforts
Require contractor demonstrate ability to produce reliable schedules that integrate design, procurement, and construction in
complex phasing scenarios
