- 4. Heavy/highway
What is the function of the Owner?
- Identifies the need
- financial backing
T/F Public owners are tax payers?
What is a developer?

- negotiating construction contracts
What is the construction project manager?
- part of the construction company
- configure the project team
- schedule the job
- set up a const control system
Compare Decentralized and centralized firms?
Decentralized shift more decisions to the filed. Centralized firms retain the bulk of the decision making to head office. Centralized firms allow similar project to be standardized.
What is the Work Breakdown Structure?
- organization of the project work.
- deliverable grouping of work elements that subdivide the work into manageable parts
Explain the three Organization charts
- 1. Generalist - vertical lines and horizontal lines
- 2. Departmental - expanding tree moving away from president
- 3. Matrix - formal lines of communication between departments
What is a Sole Proprietorship?
- Single person ownership
- High risk for the owner
What is a Partnership?

What is the basic communication loop?
Source ->Symbol->receive->feedback to source
What is a project delivery method?
combination of professionals arranged to assign responsibilities and risk in a certain way
3 most common project delivery methods?
- 3.construction management
What causes the scope to creep?
- Difficult to get a complete consensus on project scope from the beginning
- critical user is left out and must be accommodated later in the process
- communication among the user, designer, and constructor
What are the risks of going into construction to fast?
- Design elements are not thoroughly considered
- complete design documents
What are the four classifications of general risk?
- 1. Financial - will cost more
- 2. Time - will not complete within planned time
- 3. Design - will not perform adequately
- 4. Quality - incomplete work
What are the project specific risks?
- Site Risks
- The project itself
- organizational risk
What are the three general contract types?
- 1. Lump sum
- 2. Unit price
- 3. cost plus a fee
What are the steps in the Design/Bid/Build arrangement?
- 1.Owner hires a designer to design the project
- 2.with the design in hand, owner retains a contractor to build the project
Advantages of D/B/B?
- well known and understood
- contains considerable protection for owner
- allocation of construction risk is almost completely on contractor
- owner knows the final cost at the beginning
- cost overruns are borne by the contractor
- Owner does not have to be heavily involved in construction
Disadvantages of D/B/B?
- Construction professional does not have input into the design
- difficult to reduce the time required for design and construction
- Not able to fast track
- all parties work autonomously, little chance for team building
What are the steps in a Design/Build?
- 1. owner hires a design/build firm to perform both the design and construction
- 2.this firm designs, acquires materials, and deploys the labor force
Advantages of D/B
- excellent communication between design and construction teams
- project is easily fast tracked
- allows easier incorporation of changes due to scope and unforeseen conditions
Disadvantages of D/B
- generally not a fixed firm price
- owner may have to make decisions on the fly
- lack of checks and balances
- owner must rely on ethics of the firm
- does not guarantee the best possible price
What are the steps in Construction project management
- 1. owner hires both a design firm and construction project management firm in the beginning
- 2. construction project manager oversees work directly associated with construction
Advantages of Construction project management?
- good communication among owner, designer, and constructor is established early
- Allows for good value engineering
- allows for fast tracking
- subcontractors are under contract with the owner and compete for bid packages
- Owner pays designer and construction manager a fee
Disadvantages of Construction project management?
- requires good communication between owner, designer, and construction manager
- High owner involvement
What is single fixed price?
- perform a specified amount of work for a specific sum
- owner knows before the work begins what the final cost will be
- used with the D/B/B method
- if errors in the design the contract will need to be renegotiated
- fast track is not possible
What is a unit price contract?
- agreed price per unit
- eliminates risk to both the owner and the bidders
- allows a competitive bid and fair price for the work
- work can begin before design is complete
- price is not fixed and may be significantly more
- actual quantities must be measured in the field
What is Cost plus a fee contract?
- reimbursed by the owner for work costs plus additional agreed-upon fee
- good when scope is hard to define
- good to fast track project
- encourages value engineering
- contractor is responsible for any additional costs beyond the guaranteed maximum price GMP
What causes contract changes?
- 1. change in owner requirements/scope
- 2. unforseen conditions
- 3. omissions in the documents or design features
Alternate dispute resolutions?
What is an Addenda?

- 1. offer to tender
- 2. amendments to tender call
- 3. pre-tender meeting with contractors

What if lowest tender is too low?
- review your estimate
- review bid in relation to other bids
- request bidder to review his bid
- bidder cannot increase the bid price
Lowest tender is too high
- re invite lower bidders
- change project scope
- recall tender
What is a bond?
- agreement made between the principal(contractor), surety(bonding company), obligee(owner)
- security becomes liable to the obligee for the default in performing obligation
What are the four types of bonds?
- 1. bid bonds - guarantees that the contractor will enter into a contract
- 2. performance bonds - guarantees the contractor will perform the work
- 3. Payment bond - guarantees the contractor will pay all bills
compare a bond and insurance
The total amount of the bond must be paid back to the bonding agent. where insurance only get a premium back.
