3 Types of Blueprint Views
They show the different layers of the road and side slopes and ditches for a particular given length. What is a plan detail? A detail is a view of a very specific item of work T/F Typical Section Sheets show elevation views of the proposed road. False. The answer is "Profile Sheets" The shape of the road's side slopes and ditches are found on which sheet? " Typical Section Sheets" T/F The directional arrow is found on the "Profile Sheet" False. "Plan Sheets" also called "Key Sheet" Which sheet depicts the cross-section view of the road superimposed on the natural ground line? Cross-Section sheets. What is the diameter, in inches, of a #8, Re- Bar? 8 divided by 8 = 1.00" Station 21+00 is what distance from Station 23+00? 200 Is 21+00 Up Station or Back Station from 23+00? Back Station What is "Cross-Slope"?
A survey rod reads like a tape measure. It allows the surveyor to record an observed number so that an elevation can be determined. What is a Vernier? A "Vernier" is used on a survey rod and is used to determine the subdivision of the smallest division of the smallest division of a scale. Can the terms "Transit" and "Level" be used synonymously? No. A Transit can measure vertical angles whereas a level cannot. When looking through a level, what are the 4 different hair lines that you will see called? Upper Stadia, Middle Cross / Middle Stadia, Lower Stadia and Vertical Cross. What are Benchmarks? Benchmarks are fixed exact points where an exact elevation is known. What is "Back Sight"? Back Sight is a rod reading taken on a point of know elevation. What is "Height of Instrumentation" (HI) is the elevation of the line of sight projected by the instrument. What is "Fore Sight" (FS)? Foresight is a rod reading taken on any point to determine it's elevation. What is "Turning Point" (TP)? Turning Point is a reliable point upon which a foresight is taken to establish elevation.
A steel tape is used to measure the length between points "A" & "B" and the distance is found to be 95'. The temperature of the tape at the time of measurement is 45 degrees (F). If the tape is calibrated for 68 degrees (F) and no other factors are to be considered, is the measurement correct? Short or long? Why? The measurement will be too long. The tape shrunk due to the cold and principles of "Coefficient of Expansion". What is the typical tension required on a 100' steel tape? 25 LBS If a steel tape is held "off-line", is the measurement accurate? No. When measuring, tapes must be held on-line, if not, errors will occur in the actual measurement. Name the 9 most common errors that occur when measuring with tapes. Length other than standard, improper plumbing, temperature other than standard, poor alignment, tape not being horizontal (level), sagging, faulty marking, incorrect reading or interpolation. What are Catch Points? CP occur at the intersection of the existing ground and the constructed grade. The amount of cut or fill is determined by the difference between the roadway elevation and the original ground elevation. Name the 3 types of Contour Lines. Index, Intermediate and Supplementary.
A Contour Line connects all points of equal elevation, above or below a known or assumed reference point or plane. How is a depression shown on a Topo Map? Hachure or tick marks that are on the inside of contour circles denote a depression. What are the "4 Rules" of Contour Lines?
cement. What is "Wet Sieve" Used to separate fine grain from coarse grain. It carried out by washing the soil specimen on a 60pm sieve mesh.
Open graded. Trees to be saved within the R-O-W should be marked by? The Construction Engineer. Grubbing includes?
Removal of stumps, roots and stubs. Before beginning earthwork, it is important to? Verify location of underground utilities through local one call system. When backfilling culverts and storm drains, lifts are not to exceed? 6 inches. Backfill for pipes and culverts consist of? Granular materials. For fences erected on a slope, the posts are to be set in what position? Plumb Plans required a 42" high fence. If the posts are 6' long, how much of the post is in the ground? 6' x 12 = 72 72" - 42" = 30" Fence corners are strengthened by? Horizontal post and tension wire. Why are the line braces installed in long sections of fence? To retain tension at elevation changes. What is important when inspecting concrete barrier? Alignment Guardrail is 25' long. What is the center spacing of the posts if mounted on 8 posts? 8 posts means 7 spaces. 25' / 7 = 3.57' How is the thickness of paint measured? Mils
100' x 3' x 2 sides = 600 SF 12" x 2 (top and bottom) x 100' x 2 Flanges = 400 SF Total - 1000 SF Paint weighs 20lbs per gallon. If a bridge requires 200 lbs of paint and so far only 125 lbs of paint has been applied, what is the percentage completed? 125 divided by 200 =. (or 62.5% complete) What is the protective surface treatment for a concrete bridge deck? White membrane curing compound. What is the purpose of using vibrators in concrete? Consolidation Sealer treatment can be applied without being hard, even if the concrete is? Still green Excessive vibration of concrete causing the top to become white, chalky and non durable is called? Laitance The main reason for applying liquid membrane forming compound on concrete is? Preventing loss of water during early curing. The main reason for white reflective concrete covering is? Reduce temperature in concrete and reflect the sun's heat. What does a screed do? Removes excess concrete from the surface of freshly placed concrete.
If told in the above problem the specifications requires a 30% increase in the quantity for the protective coating, how many gallons are required? 84.4 gallons x 1.30 = 109. gallons Concrete pipe should be placed?
dry soil particles. Define Optimum Moisture Content? The degree or percentage of moisture in soil at which the soil can be compacted to it's greatest density.
What are the ACI testing procedures? Temp, Air by Volumetric method, Air Content by Pressure method, Slump, Unit Weight and Cylinders. Slope stakes are set using which instrument? Level Horizon and vertical angle may be measured by? Transit Sum four distances: 66 ft + 6.600 ft + 66 inches + 6.6 inches 78.65 fT What does the letter "D" mean if referring to the alignment of a road? Degree of curvature. Regulatory Traffic Signs are typically? Black letters on white background. The sides of trenches need to be shored, braced or sloped if the excavation exceeds? 5 feet The contractor is responsible for which OSHA requirements? All What is inspection's first priority? The safety of the public OSHA requires nets to be placed under work when work is how many feet above the ground or water? 25 feet
Orange and white The standard height of Type 1 and Type II construction barricades is? 3 Feet The minimum height of construction signs on a temporary movable support is? 6 Feet Where should advanced construction warning signs be placed on a highway? 1 mile How do you best relieve the pain of a first and 2nd degree burn?

False A tandem 2 wheel roller used for compacting asphalt weighs approximately? Varies from 2 - 8 tons. An asphalt mix may flatten in a truck during delivery due to? Excessive asphalt in the mix or if the mix is too hot. A stiff asphalt mix is caused by? The mix being too cold. How many feet in a mile? 5280 feet in a mile After the project no longer needs temp pavement markings, what should be done with them? Temporary pavement marking should be eradicated and permanent markings should be installed.
Which document is a standard for construction barricades, protective devices and warning signs? MUTCD What is an inspector to do after the contractor has placed signage to route traffic on a temporary rd? Record the signage, compare against the plans and continue to check the signage regularly. Fertilizer application rate for a flat surface is how many lbs per acre? Check the spec. 800lbs per acre How can a contractor assure that there will be adequate amounts of topsoil on a job? Through the use of Cross-Sections. Compare current Cross Section condition and compare against the original. When stockpiling topsoil on a site, stockpiles should? Keep away from trees, away from drainage and in a centrally located location. Clearing and grubbing on a rural 2 lane highway will normally be paid by? Acres The beam supporting the masonry over an opening in a wall is? Lintel What measures surface irregularities on a gauge as it is pushed along the surface?
