Water Resources and Environmental

payback period

Period of time required for the profit or other benefits of an investment to equal the cost of the investment

MARR

Minimum acceptable rate of return - the interest rate one is willing to accept or the rate that one desires to earn on investments

Rate of return

Interesting rate that makes the benefits and costs equal

Where do you look for interest rate tables?

Section 1.7.10 of the NCEES PE Civil Handbook

Average end-area method for earthwork

Calculates volume V between two consecutive cross sections as the average of their areas multiplied by the distance between them, where fill is positive and cut is negative

Primordial formula for earthwork

Calculates volume V between two consecutive cross sections, taking the area of the midsection into account

Benchmark

Permanent point of know elevation

Turning point

Point temporarily used to transfer an elevation

Cost index

Used to update historical cost data to the present (if purchase cost in specific year is known, current cost can be found)

Resource scheduling

Tabulating project resource demands over time

Resource leveling

Minimizing resource conflicts either by adjusting the start times of activities to reduce peak demand for resources, sometimes within float, or by extending activity durations to reduce peak demand within a constrained resource limit.

Time-Cost Trade-Off

A strategy for optimizing project time and cost either by identifying least-cost solutions for adding resources to shorten the the duration of critical path activities or by identifying least-time solutions for reallocating resources over an extended duration of critical path activities to reduce total project cost

How often are strength tests taken of each class of concrete placed placed each day?

Not less than once a day or less than once for each 150 yd3 of concrete nor less than once for each 5,000 ft2 of surface area for slabs or walls.

When are strength tests not needed for concrete placed?

When the total quantity of concrete is less than 50 yd3 as long as evidence of satisfactory strength is submitted and approved by the building official
