Which of the following is the Program Evaluation and Review Technique (PERT) used? - ANSWER PERT is
used to monitor the progress and predict the completion time for large projects.
-construction projects
-computer programming assignments
-preparation of bids and proposals
Which of the following duties would normally be a responsibility of the estimating department within a
general contractor's organization? - ANSWER The estimation process does not include tracking costs or
recording actual expenses. The following is involved: obtaining bid documents, securing
subcontractor/material quotations, and delivering competitive or negotiated proposals
In competitive bidding, when the bids are all opened, the owner will normally award the contract to the
lowest - ANSWER The lowest responsible bidder is the lowest bidder whose offer best responds in
quality, fitness, and capacity to fulfill the particular requirements of the proposed project, and who can
fulfill these requirements with the qualifications needed to complete the job in accordance with the
terms of the contract.
The term "design-build" means the - ANSWER Design-build is a process where the client interacts only
with a single entity, the "design-builder." While the design-builder is usually the general contractor, it
can also be the design firm or a partnership consisting of the design firm and contractor.
An activity is coded as 0793-31 62 13.16 using the Construction Specifications Institute's MasterFormat
2012. This coding represents - ANSWER driving a deep foundation pile
Which of the following organizations is a contributor to the standard design and construction contract
documents developed by the Engineers Joint Contract Documents Committee (EJCDC)? - ANSWER -
National Society of Professional Engineers
-Construction Specifications Institute
,FE Concept Questions 179 Correct

-Associated General Contractors of America
What factor is responsible for an increase in production rates as a new task is repeated and practiced? -
ANSWER The learning curve is responsible for the usual increase in production rates as workers become
skilled at a given task.
What does the crane hand signal shown mean? (hand raised out with fingers open) - ANSWER Hand
signals in the crane industry are standardized. This signal means to lower the boom and raise the load. If
the fingers were not shown (a fist was being made), the signal would mean to lower the boom only
[OSHA 29 CFR 1926.550(a)(4)].
In addition to protective goggles, what personal protective equipment is required when welding pipe in
a deep trench? - ANSWER OSHA does not normally consider an open trench to be a confined space.
Although there are some combinations of base metals and rods that produce toxic fumes and would
require respirators, these are rare in normal construction work, so welding in a trench would not
normally result in the accumulation of toxic gases or the need for a respirator. A hard hat is always
required [OSHA 29 CFR 1926.100].
Which of the following is generally attributable to hard water? - ANSWER Hard water interferes with
foam/bubble formation, turning soap into scum.
-scum rings in bathtubs
-stains on porcelain bath fixtures
-scale buildup in boiler tubes
A fate and transport study was performed on phosphorus in a small pond. Biological processes in the
pond biota convert phosphorus to a nonbioavailable form at the rate of 22% per year. Recycling of
sediment phosphorus by rooted plants and by anaerobic conditions in the hypolimnion converts 12%
per year of the nonbioavailable phosphorus back to bioavailable forms. Runoff into the pond evaporates
during the year, so no change in pond volume occurs. Which of the following actions would best reduce
the phosphorus accumulation in the pond? - ANSWER -reducing use of phosphorus-based fertilizers in
the surrounding fields
Hardness in natural water is caused by the presence of which of the following? - ANSWER Hardness in
natural water is caused by the presence of polyvalent metallic cations.

In aquatic systems, phosphorus recycling is significantly aided by which of the following? - ANSWER In
aquatic systems, phosphorus recycling is significantly aided by algae, macrophytes, and phytoplankton.
Which of the following are sources of color in water? - ANSWER Copper, iron, and manganese ions, and
industrial colloidal solids are all sources of color in water.
Which of the following processes is used to measure the amount of acid in water? - ANSWER Titration is
used to measure the amount of acid in water.
Acidity in water is typically specified in terms of which of the following? - ANSWER The measurement of
acidity in water is typically given in terms of the CaCO3 equivalent that would neutralize the acid.
The National Primary Drinking Water Regulations apply to every public water supply serving at least how
many service connections? - ANSWER Every public water supply serving 15 or more service connections
must meet the National Primary Drinking Water Regulations.
The molar nitrogen-to-phosphorus (N:P) ratio for ideal algae growth is which of the following? -
ANSWER The molar N:P ratio for ideal algae growth is 16:1.
In water, excess amounts of which of the following can contribute to methemoglobinemia, or "blue
baby" syndrome? - ANSWER Excess amounts of nitrate in water can contribute to methemoglobinemia.
Primary treatment of wastewater consists of - ANSWER The primary treatment of wastewater is the
removal of solids and particles.
Which of the following diseases should be of concern to the environmental engineer when designing,
operating, or managing water supply projects? - ANSWER Items I through IV are not concerns: AIDS is
not a waterborne disease; Rocky Mountain spotted fever is passed to humans by ticks; botulism is
foodborne or can enter the body through contaminated soil or needles; and tuberculosis is spread by
inhalation of infectious droplets.
