FE CONCEPT QUESTIONS AND ANSWERS
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
-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.
Legionnaires' disease, on the other hand, is associated with heat transfer systems, warm temperature water, and stagnant water. Hepatitis A can also be spread through contaminated water.
Which of the following substances are used to remove calcium and magnesium from hard water? - Answer-Lime and soda ash are used to remove calcium and magnesium from hard water.
Water is recarbonated after it has been softened to - Answer-Water is recarbonated after it has been softened to lower its pH and reduce its scale-forming potential.
In addition to lime-soda treatment, what method can be used to reduce the hardness of water? - Answer-Various ion exchange methods are used to replace multivalent ions such as calcium (Ca++) and magnesium (Mg++) with monovalent ions such as sodium (Na+).
Noncarbonate hardness can be removed by which of the following? - Answer-
Noncarbonate hardness cannot be removed by heating. It can be removed by precipitation softening processes (typically, the lime-soda ash process) or by ion exchange processes using resins selective for ions causing hardness
Which of the following are generally true for water treatment relative to the adsorption of
a contaminate by activated carbon? - Answer-Adsorption is a physical process wherein the contaminant adheres to the surface of an adsorbent such as granular activated charcoal. Following saturation, the adsorbent can be reactivated in a number of ways and reused. Adsorbents are particularly effective at removing large organic molecules from the processing stream.
