What is Construction?
 Application of art and science
 Inherently dangerous
 Organized chaos
 Mankind using creativity, knowledge, strength,
determination, and persistence to control his
environment
Construction Methods & Management
CIEG 486-010
Construction differs from manufacturing
in that:
•
Not performed in controlled conditions,
therefore highly impacted by weather and
other environmental conditions
•
Seasonality
•
Each project is unique
•
Remotes sites with various access problems
Construction Methods & Management
CIEG 486-010
Construction differs from manufacturing
in that:
•
Process is not as predictable
•
Difficulty in applying automation
•
High potential for encountering unforeseen
conditions
•
Costs can vary according to conditions
Construction differs from manufacturing
in that:
•
•
•
•
•
Difficult to manage and supply utilities and other
resources.
Technical innovations are adopted slower.
Success is dependent upon the quality of its
people.
Very custom-oriented
Product can be of mind-boggling size, cost, and
complexity
Problems Facing Construction
Industry:
•
•
•
•
•
Highly traditional and fragmented; slow to
embrace new technology
Restrictive/outdated building codes
Labor agreements and craft jurisdictional
issues
Liability and legal considerations
Lack of profit motive or other incentive
Problems Facing the Construction
Industry:
•
Government regulation
•
Environmental constraints
•
NIMBY syndrome
•
Global competition

Project Delivery Organization
•
•
•
•
•
Construction by owners forces
Owner-managed construction
Construction by general contractor
Design-build team
CM Contract
Construction Methods & Management
CIEG 486-010
 Construction employing owner forces
– Usually small in-house construction or
renovations
– Industrial projects or institutional (such as
hospitals or schools
 Owner-managed construction
– Residential/commercial building developers
– Industrial or institutional
Construction Methods & Management
CIEG 486-010
 Construction by General Contractor
– Also referred to as “Prime Contractor”
– Most common method of delivery
– Contractor bears substantial risks and
financial responsibility
– Facility designed by in-house
architect/engineer or by design consultants
– Often requires specialty subcontractors
Specialty contractors might include those
specializing in one of the following:
• Excavation
• Steel erection
• Concrete
– Cast-in-place
– Prestressed/Precast
• Masonry
• Timber/wood framing
• Piping/plumbing
•
•
•
•
•
•
Clearing and grubbing
Blasting/demolition
Electrical
Painting
HVAC
Environmental
remediation
• Many, many others
Construction Methods & Management
CIEG 486-010
 Design-Build (Turnkey)
– Single firm or team responsible for design and
construction minimizes coordination problems
– More efficient designs with the interjection of
constructibility and innovation
– Often employs fast-track construction
– Benefits include reduced overall delivery time and “onestop shopping” for the owner
– Disadvantages include complexity of evaluating
proposals
Construction Methods & Management
CIEG 486-010
 CM Contract -- Fee (management services
only) also referred to as “Agency”
– Specialized construction skills through all project stages
including preconstruction
– Provides close coordination between design and
construction
– Eliminates impact of conflicts of interest
– Independent and objective evaluation of costs,
schedules, and performance
– Potential saving in time and cost
– Disadvantages include no risks associated with costs
increase
Construction Methods & Management
CIEG 486-010
 CM Contract – “At-Risk”
– CM assumes financial risks similar to a GC
– CM manages all phases of the work without
performing any actual work tasks
– CM’s only resources are management personnel
– Contractors/subcontractors have a direct contract
privity with CM
– Contract form is often a negotiated guaranteed
maximum price arrangement
– Disadvantages includes lack of impartiality
