b) False

13) If practical, the foundation should be located on uniform soils subject to the least swelling or volume change. Discontinuities or significant lateral variations in the soil strata should be avoided. Special attention should be given to adequate compaction of filled areas, types of fill, and leveling of sloped sites.br>

  a) True
b) False

14) Undeveloped sites generally do not need any subsurface exploration.

  a) True
b) False

15) Substantial differential heave may occur beneath structures constructed on previously undeveloped sites where trees and other heavy vegetation reduce the transpiration of moisture. Construction of the foundation over the soil will tend to further increase soil moisture because of reduced evaporation of moisture from the ground surface.

  a) True
b) False

16) Future irrigation of landscaped areas and leakage from future sewer and other water utility lines following development of the site may substantially increase soil moisture and cause a water table to rise or to develop if one had not previously existed. Filled areas may also settle if not properly compacted.

  a) True
b) False

17) Borings should be spaced to define the geology and soil nonconformities. Spacing of 50 or 25 feet and occasionally to even less distance may be required when erratic subsurface conditions (e.g., soils of different swelling potential, bearing capacity, or settlement) are encountered. Initial borings should be located close to the corners of the foundation, and the number should not be less than three unless subsurface conditions are known to be uniform. Additional borings should be made as required by the extent of the area, the location of deep foundations such as drilled shafts, and the encountered soil conditions.

  a) True
b) False

18) According to table 4-1 soils that have a liquid limit LL of less than 50 percent, Plasticity index PI less than 25 percent and natural soil suction less than 1.5 their classification for potential swell is:

  a) Low
b) Marginal
c) High

19) The foundation soil may expand both vertically and laterally. The vertical movement is usually of primary interests, for it is the differential vertical movement that causes most damages to overlaying structures.

  a) True
b) False

20) A slab constructed on the ground surface of a wet site may in time lead to downwarping at the edges after a long drought or growth of a large tree near the structure.
  a) True
b) False
21) Edge uplift may occur following construction on an initially dry site (fig 5-3 b)

  a) True
b) False

22) The foundation of the structure should be designed to eliminate unacceptable foundation and structural distress. The selected foundation should also be compatible with available building materials, construction skills, and construction equipments. The foundation should be designed and constructed to maintain or promote constant moisture in the foundation soils. For example, the foundation should be constructed following the wet season if possible. Drainage should be provided to eliminate ponded waters. Excavations should be protected from drying.

  a) True
b) False

23) In preparation for construction, the foundation should always be provided with adequate drainage, and the soil properly prepared to minimize changes in soil moisture and differential movement. Existing trees and other heavy vegetation should be removed. New plantings of like items installed during post construction landscaping should not be located within a distance always from the structure ranging from 1 to 1.5 times the height of the mature tree.

  a) True
b) False

24) In case #7 (of Ethics section); It was alleged that Dr. Smith conducted an engineering inspection for his client in December 1998; but did not provide his client with his inspection report until February 2000. This Indicated that he was not acting as a faithful agent for his client and his actions were not in keeping with generally accepted engineering standards and procedures. The Board accepted a Consent Order signed by Dr. Smith for a formal reprimand.

  a) True
b) False

25) In case #11 (of Ethics section); It was alleged that Mr. Doe, a Texas PE engineer, altered boundary information on Survey plats for a subdivision that had been prepared by a license surveyor, affixed a copy of the surveyor's seal to the plats and submitted the plats to county officials for approval without knowledge of the surveyor. The Board reportedly suspended his license for one year and fined him $1000.00

  a) True
b) False

26) In case # 15 (of Ethics section); It was alleged that Jim, the company's president, designed seven swimming pools and affixed a copy of a Texas Professional engineer's seal and signature that he had obtained from another source to the plan sheets which were submitted to a city for permitting. Board records did not show that Jim was licensed as a professional engineer in Texas nor that his company had Texas professional engineer as a regular full-time employee. The Board accepted an Agreed Board Order signed by Jim to cease and desist from any and all representations that his company can offer and/or perform engineering services and from the actual performance of engineering services until such time as the company hires a Texas licensed professional engineer as a regular full time employee, and to immediately discontinue the use of the Texas professional engineer's seal and signature on any and all documents. Jim also agreed to hire a Texas professional engineer to perform after the fact engineering inspections and issue certification reports for the five swimming pools that were permitted and constructed. The company was also ordered to pay a $5000.00 administrative penalty.

  a) True
b) False

27) In case #17; John was a registered engineer in:

  a) Texas
b) Michigan
c) New Mexico

28) In case #21; It was alleged that Billy signed his name and affixed his Texas Architectural seal to structural, mechanical, electrical and plumbing design plans for renovation of a commercial building. Based upon the size of the building, the structural, mechanical, electrical and plumbing designs were required by law to have been performed by a licensed professional engineer; therefore Billy's preparation of these design plans constituted the unlawful practice of engineering. The Board accepted a consent order signed by Billy and his attorney agreeing that Billy will not practice engineering outside the exemption listed in the Engineering practice Act and will refrain from making any and all representations that he can offer and/or perform engineering services until such time as he hires a Texas licensed professional engineer as a regular full time employee or until such time as he becomes a Texas licensed professional engineer. Billy also agreed to pay a $1000.00 administrative penalty.

  a) True
b) False

29) In case #6; It was alleged that Jim provided professional engineering design services in connection with residential foundation design and exterior wall systems during a period when his Texas engineer license was expired.

  a) True
b) False

30) In case # 24; John-David-Bill, Inc. It was alleged that site grading and drainage plans for two projects were submitted to the city of Brownsville, one set bearing John's signature and architect seal and the other bearing David's signature and architectural seal. The size and scope of the respective projects required that Texas licensed professional engineers prepare the grading and the drainage design plans. Board records did not show any of the three were licensed as professional engineers in Texas nor that their company had any regular full time employee who was licensed as professional engineers in Texas. Therefore it appears these individuals unlawfully performed engineering services and their respective plans were an unlawful representation of their company ability to offer and /or perform engineering services. The Board accepted a Consent order signed by the president of the company to cease and desist from practice of engineering and from any and all representations that the company can offer of performing engineering services until the such time as the firm hires a full time employee who is licensed as a professional engineer in Texas. The company also agreed to pay a $2000.00 administrative penalty.

  a) True
b) False
