Lecture 4: Project delivery systems Flashcards
The traditional project delivery system
involves three main parties:
- The Owner
- The Architect/Engineer (A/E)
- The Contractor(s) and his/her subs
Is the Owner’s agent and fiduciary.
The A/E
The relationship between the Owner and
the Contractor is usually an _______.
adversarial relationship
Traditional Project delivery System:
- Design
- Bid
- Build
What is the A/E responsible for under deign-bid-build?
1. Representing the owner during the construction stage 2.Observing the work for conformance with contract requirements 3. Observing project progress for review of contractor applications for payment 4. Preparing and recommending contract modifications 5. Attending project meetings 6. Inspecting the project to determine substantial and final completion
What is the Owner responsible for under Design-Bid-Build?
The owner is typically responsible for:
- Making periodic payments to the contractor
- Approving contract modifications involving changes to contract time or price
What is the project manager’s job under design-bid-build?
- Preparing
applications for payment - Administering subcontracts
- Purchasing
- Preparing, monitoring, updating, and revising project schedules
- Attending project meetings
- Communicating with the A/E and subcontractors
- Preparing proposal requests and responding to A/E issued contract
modification
proposals - Preparing and implementing safety programs
- Requesting clarifications and interpretations of the contract documents
- Administering the submital process
A form of design-bid-build where all parties are brought in at beginning. Stages of design and construction are
overlapped. Time from conception to occupancy is substantially reduced. A construction manager is used to
coordinate between all parties
Phased or “Fast Track”
Construction
1. Owner, designer, engineers, general contractors and mechanical and electrical specialty contractors form a team to develop design 2. General contractor evaluates design’s cost and time implications 3. This allows designer to maintain owner’s goals within budget, sometimes leads to major design changes which could not be made later
The design phase of Phased or “Fast Track” Construction.
- Construction Phase
- Project is being designed, bid, and
built in stages - Excavation, foundations, structure
are bid and started before design
work is finished - Mechanical and electrical are bid
and built while finishing and partition
work are still being designed
The construction phase of Phase or “Fast Track” construction.
A “pure” construction manager (Agency CM )will not guarantee a budget or schedule nor will they perform any work on site ______.
(CM for fee or ACM)
A general contractor acting as a
construction manager will guarantee
both and perform work that is critical
to control cost and schedule
(CM at risk)
1. Technology/process dependent 2. Used in industrial construction 3. Requires significant amount of engineering 4. Mechanical/electrical systems (piping, instrumentation) 5. Typically involve large pieces of engineered equipment (paper machine, vessels)
Engineer/Procure/Construct
EPC
Common problems with the traditional
approach include:
- Cost overruns
- Schedule delays
- Changes and modifications
- Claims and disputes
- Constructability issues
- is a project delivery system
that can be used as an alternative to the
traditional approach (Design/Bid/Build) - The project Owner consolidates the
Liabilities/Responsibilities into one party
(The design/builder)
Design/build
What are the six stages of Design/build?
- Project initiation
- Risk Allocation
- Performance specification
- Project Planning
- Construction Administration
- Project Closeout
- Starting point where the Owner defines needs and
expectations - Consultants and financial planners assist the Owner
in determining project objectives, budget, and financial resources
Design/build Project initiation
Project initiation Includes answers to what 8 issues?
- Benefits and cautions of the delivery system
- Program and feasibility studies
- Project timeline
- Budget and contingencies
- Project financing
- Life
- cycle options
- Project design alternatives
