About NCEESThe National Council of Examiners for Engineering and Surveying (NCEES) is a nonprofit organization

made up of engineering and surveying licensing boards from all U.S. states and territories. Since its

founding in 1920, NCEES has been committed to advancing licensure for engineers and surveyors inorder to protect the health, safety, and welfare of the American public.

NCEES helps its member licensing boards carry out their duties to regulate the professions ofengineering and surveying. It develops best-practice models for state licensure laws and regulations and

promotes uniformity among the states. It develops and administers the exams used for engineering andsurveying licensure throughout the country. It also provides services to help licensed engineers and

surveyors practice their professions in other U.S. states and territories.

Updates on exam content and proceduresVisit us at ncees.org/exams for updates on everything exam-related, including specifications, exam-day policies, scoring, and corrections to published exam preparation materials. This is also where you will

register for the exam and find additional steps you should follow in your state to be approved for the

exam.

Exam-day scheduleBe sure to arrive at the exam site on time. Late-arriving examinees will not be allowed into the exam

room once the proctor has begun to read the exam script. The report time for the exam will be printed onyour Exam Authorization. Normally, you will be given 1 hour between morning and afternoon sessions.

Admission to the exam siteTo be admitted to the exam, you must bring two items: (1) your Exam Authorization and (2) a current,

signed, government-issued identification.

Examinee GuideThe NCEES Examinee Guide is the official guide to policies and procedures for all NCEES exams. All

examinees are required to read this document before starting the exam registration process. You candownload it at ncees.org/exams. It is your responsibility to make sure that you have the current version.

NCEES exams are administered in either a computer-based format or a pencil-and-paper format. Each

method of administration has specific rules. This guide describes the rules for each exam format. Refer

to the appropriate section for your exam.

Scoring and reporting NCEES typically releases exam results to its member licensing boards 8–10 weeks after the exam.

Depending on your state, you will be notified of your exam result online through your MyNCEESaccount or via postal mail from your state licensing board. Detailed information on the scoring process

can be found at ncees.org/exams.

501. A segment of interstate highway requires the construction of an embankment of 500,000 yd3.

The embankment fill is to be compacted to a minimum of 90% of Modified Proctor maximum

dry density.

A source of suitable borrow has been located for construction of the embankment. Assume that

there is no soil loss in transporting the soil from the borrow pit to the embankment.

The following data apply:

Dry unit weight of soil in borrow pit 113.0 pcfMoisture content in borrow pit 16.0%

Specific gravity of the soil particles 2.65

Modified Proctor optimum moisture content 13.0%Modified Proctor maximum dry density 120.0 pcf

Assuming each truck holds 5.0 yd3 and the void ratio of the soil is 1.30 during transport, the

minimum number of truckloads of soil from the borrow pit that are required to construct the

embankment is most nearly:

(A) 100,000(B) 150,000

504. Reference: Schexnayder and Mayo, Construction Management Fundamentals, 2004, Chapter 6.

B is the turning point where the job goes from excavation to a fill operation. D is the point where

it goes back to excavation. Therefore, B–D is the fill operation (Statement II), and D is atransition point (Statement III). Statements II and III are true.

THE CORRECT ANSWER IS: (D)

505. Reference: Peurifoy, Schexnayder, and Shapira, Construction Planning, Equipment and Methods,

7th ed., p. 98.

Both shrink and swell can be estimated. Shrink is the relationship between the in-place (bank)

and compacted states. Dry density in-place can be estimated from tests on rings. Compacted drydensity can be estimated from ASTM D698. Swell can be estimated from gradation (soil type).
