PM Exam II Flashcards
What are some of the design features of the bridge ( i.e. type of bridge, height of towers, weight and length of beams, cable design/construction, and other design facts) ?
It is a cable stay bridge. The towers are 550 feet tall concrete towers. 64 road deck sections. 200 feet above cooper river. 40 ton pieces of steel. Longest cable stay bridge in North America. 11 footings per tower, 10 feet in diameter, that are 100 feet deep, and shafts are dug 230 feet deep.
How was the bridge designed/constructed to withstand earthquakes, hurricanes and supertanker ships from colliding with the bridge?
Footers designed to protect against earthquakes.
Islands around main towers prevent against ships running into them.
Cables and Footers work together to provide resistance to protect against hurricane winds.
Identify the management styles (characteristics) of the local vs. non-local superintendents/foremen. Which ones were effective and not effective?
one was micromanaging, the other?
What were some of the site logistic challenges in terms of:
A. Getting workers to the job site?
B. Getting Materials ( i.e. concrete and steel beams) to the jobsite?
C. Sharing the cranes on the jobsite?
A. Workers ride from dock to main towers on a boat.
B. Materials such as concrete were put on a barge and a tugboat would push them to the bridge, then they would use a crain and bucket to get the concrete up to the working surface of the bridge.
C. Coordination between tower crews and tug boat availability.
Describe the material laydown area on the bridge (materials, accessibility, ect.)
The major laydown area was an old naval ase down the river about 1 miles. Not much laydown area on bridge. Major materials have to be brought in by barge and put up in sections. This insures that the bridge stays balanced.
What contributed to inefficiencies in labor productivity during the construction of the bridge?
Material delivery delays due to not having the tug boats when they wanted them. Plus the time it took to place the materials on the barges. Having to find a barge/ waiting on the barge.
Describe at least 2 of the quality control issues on this project.
The tensioning or the cables and mortar and concrete had to be perfect.

To beat estimated profit.
How do you beat the estimated profit?
Labor savings- maybe
Material Savings
Subcontractor Savings
Equipment Savings
Buying out is mainly preformed by whom?
the project manager
What is a subcontract interview form?
Is a checklist to ensure that all items required of the particular subcontractor are discussed during the interview proecss, including the scope of work to be completed and its corresponding cost.
What prevents a subcontractor from later stating they misunderstood the points during the interview and that they did not include or exclude specific items?
The subcontractor’s signature on the subcontractor negotiation form.
What does a Bid summary sheet contain?
It includes the prjoect name, scope of work represented, the bid price, and the budget estimate for the item is a document that can be transmitted to the owner.
What are the main questions to ask subcontractors during negotiations?
Have the latest contract drawings been reviewed, and do the subcontractors accept all revision dates as being part of their bid?
If the project is exempt from state sales tax, does the bid reflect this exemption, and conversely, if the project is not tax exempt are the appropriate taxes included in the bid?
Are the subcontractors aware of the project schedule?
Are any exceptions being taken to the scope of work as shown on the contract drawings or the specifications?
What are the main arguments about cleaning?
The subcontractor was not notified that they would be backcharged if their cleaning was not completed by a specific date.
The subcontractor denies responsibility for generating all, or some, of the debris the general contractor claims.
