About NCEES The 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 in order 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 of engineering 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 and surveying 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 procedures Visit 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 schedule Be 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 on your Exam Authorization. Normally, you will be given 1 hour between morning and afternoon sessions. Admission to the exam site To be admitted to the exam, you must bring two items: (1) your Exam Authorization and (2) a current, signed, government-issued identification. Examinee Guide The 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 can download 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 MyNCEES account or via postal mail from your state licensing board. Detailed information on the scoring process can be found at ncees.org/exams.

(A) 1,110 (B) 250 (C) 150 (D) 100




131. The Standard Penetration Test (SPT) is widely used as a simple and economic means of obtaining which of the following?

(A) A measurement of soil compressibility expressed in terms of a compression index

(B) A direct measurement of the undrained shear strength

(C) An indirect indication of the relative density of cohesionless soils

(D) A direct measurement of the angle of internal friction 132. A department of transportation must remove and replace a 12-ft 20-ft concrete slab on an

interstate facility. To minimize disruption to traffic, the work must be completed during an 8-hour nighttime work shift. Nighttime temperatures average 50F. If the minimum required compressive strength is 3,500 psi, the concrete mix would most likely consist of:

(A) coarse aggregate, sand, Type II cement, chemical accelerator

(B) sand, Type III cement, water, chemical accelerator

(C) coarse aggregate, sand, Type V cement, water, chemical accelerator

(D) coarse aggregate, sand, Type III cement, water, chemical accelerator 133. Fatigue in steel can be the result of:
