Materials & Resource Management Flashcards

A crew's productivity drops after a long run of scheduled overtime. What is the most likely cause?

Answer: Fatigue and declining efficiency from sustained overtime

Sustained overtime causes fatigue, so output per hour falls the longer it continues.

What is the main advantage of prefabricating MEP assemblies off site?

Answer: It improves quality control and cuts field labor and congestion

Shop prefabrication happens in a controlled setting, which improves quality and reduces on-site labor and trade congestion.

A stored-materials payment request for items held off site usually requires:

Answer: Proof of insurance, title transfer documentation, and owner approval

Owners usually require bills of sale, insurance, and sometimes inspection before paying for materials stored off site.

In a crane lift plan, which factor determines the capacity required for the lift?

Answer: Total load weight including rigging, at the maximum radius

Required capacity includes the load plus rigging (hook block, slings, spreader bars), checked at the worst-case radius.

Material laydown areas should be planned mainly to:

Answer: Minimize double-handling and keep materials close to where they will be installed

Good laydown planning cuts rehandling and travel time while staying clear of work areas and access routes.

For federally funded projects, Buy American requirements affect material management mainly by:

Answer: Requiring documentation that covered materials are domestically produced

Buy American/Build America provisions require certification and documentation of domestic content for covered materials.

Which equipment metric compares the hours a machine actually works with the hours it is available on site?

Answer: Utilization rate

Utilization rate shows how effectively equipment is used, and low utilization points to excess fleet or poor scheduling.
