Construction Administration Flashcards
The general contract method
Design- bid- build/ Design - estimating - construction
Brokerage
When the general contractor subcontracts all the work on a project. It’s not beneficial to the owner.
Many owners place contractual limits on the amount of work that can be sub-contracted. Contract statement
“ The contractor shall perform with his or her own organization not less than 25 percent of the work”.
The methods of construction contracting
- General contract method
- Separate contracts method
- Self -performance method
- Design- build method
- Professional constuction management method
- CM at risk
The pros and cons of GC method
Gives the owner a firm idea of the final cost of the total project prior to construction phase. Clearly defined roles for each of the contracting parties. Minimizes the contractual liability for cost overruns and late project delivery.
Often extends the project duration. The owner doesn’t have an agent involved in the contractual arrangements. Leads to tight bids and small profit margins. Might lead to bad performance. Inflexible.
Separate contracts method
Owner as GC with multiple prime contracts.
Pros and cons of Separate contracts method
Save money,
Require in-house capabilities to manage a construction project. Or hire a management firm, but the power of this firm won’t be as great as GC. Greater risk for owner.
The profit earned by the GC is usually
Less than 3%
Self-performance method/ force account work
Owner do the construction work in-house
The pros and cons of self-performance method
Save time and money
Unfair in public works.
Self- performance is common for
The maintenance of county roads, maintenance of railroad tracks… small scope, ongoing projects.
When the contractor defaults on the contract and the owner must step in to finish the project.
Design-build/ design-construction/ turnkey
Single contract for both design and construction of a project.
Pros and Cons of design build
Higher degree of constructability; fewer changes due to design error. Possible for construction to begin before finishing design. Usually the lowest cost, 20-30% faster
The dispute can still arise between design and construction firm. Less checks and balances in the process. Less control by the owner. On public projects, there are usually restrictions on the process.
Design build method is popular in projects
Large, industrial- type projects. When project is large and technically complicated.
Professional construction management method
Owner hires a professional construction management firm (CM)
The contract for design build is generally established as
fixed fee+ cost with GMP
The pros and cons of CM
CM works for the owner’s benefit. Allow flexibility for changing the project as the design evolves. Save time.
Owner need to trust CM
The payment for the CM
Flat fee/ shared cost savings/ cost+ percentage.
Cost: service + stated multiplier to cover other items like travel expenses, training, inspections…
The CM often gives the owner a GMP
CM is usually used when
The project is large or complex when construction expertise is needed during design phase. E.g. hospitals.
CM at risk
CM as independent contractor. or CM/GC
Contract for CM at risk
Cost + fixed fee with GMP
Difference between CM at risk and GC
CM at risk enters the contract prior to design completion.
