1Before excavating for a metal-building foundation in South Carolina, an excavator must notify SC811 and wait how long for locators to mark underground facilities?
A.Three full working days, not counting the day the request is submitted, weekends, or holidays
B.Until the same calendar day if the call is made before noon
C.One calendar week including Saturday and Sunday
D.Fifteen calendar days before any stake is driven
Explanation: The SC811 Excavator Manual requires three full working days after a normal locate request is submitted. That wait does not include the request day, weekends, or holidays. Excavation may begin on the next working day only after the excavator has checked positive response and the marks are in place.
2After utilities are marked, the SC811 Tolerance Zone for most excavation is:
A.12 inches on either side of the paint mark only
B.18 inches measured from the trench spoil pile
C.24 inches on either side of the utility mark, plus one-half the diameter of the facility if known
D.36 inches from the building column line regardless of marks
Explanation: SC811 defines the Tolerance Zone as 24 inches on either side of the utility mark plus one-half the facility diameter when that diameter is known. Mechanized equipment is prohibited in that zone until the excavator has visually identified the facility, or confirmed none is present, to the excavation depth. Hand digging or vacuum excavation is the required method inside the zone.
3A normal SC811 locate request remains valid for how long from its start time?
A.72 hours including weekends
B.7 calendar days
C.15 working days
D.30 calendar days with no renewal required
Explanation: A normal SC811 locate request is valid for 15 working days from its start time. After it expires, a new request must be submitted before excavation continues. Marks that fade or are destroyed also require a remark before work proceeds.
4White paint, flags, or stakes used to outline a planned excavation on a metal-building site are called:
A.White lining of the proposed excavation limits
B.Pink survey control
C.Yellow gas-line confirmation
D.Red electrical isolation
Explanation: APWA/SC811 color code assigns white to proposed excavation limits or route. White lining the dig area before the locate request helps locators mark only the work zone and reduces missed facilities. It is a required safe-digging practice on commercial sites.
5Finished site grading around a pre-engineered metal building should primarily:
A.Pond stormwater against the slab to increase soil moisture under the footings
B.Slope the grade toward the building so downspouts can discharge at the columns
C.Provide positive drainage away from foundations and slabs to protect bearing soils and limit moisture intrusion
D.Leave the perimeter flat so crane mats can sit in standing water
Explanation: Positive drainage moves surface water away from footings, piers, and slabs so bearing soils do not saturate and so moisture does not enter the building. Poor drainage can undermine foundation support, stain panels, and cause interior condensation problems. Downspouts should discharge well away from the foundation.
6OSHA 29 CFR 1926.651 requires excavated spoil and other materials that could fall or roll into an excavation to be kept at least how far from the edge, unless a sufficient retaining device is used?
A.6 inches
B.12 inches
C.2 feet
D.6 feet
Explanation: OSHA 1926.651(j)(2) requires spoil, equipment, and other materials that could fall or roll into an excavation to be kept at least 2 feet from the edge, or retained by devices that prevent them from entering. The setback reduces surcharge on the trench wall and keeps material from striking workers. A competent person must also watch for changing soil conditions.
7Unless the excavation is in stable rock or a competent person finds no cave-in potential, OSHA 1926.652 requires a protective system when employees enter an excavation that is:
A.Any depth once a ladder is present
B.Less than 4 feet deep
C.5 feet deep or greater
D.Only 20 feet deep or greater
Explanation: OSHA 1926.652(a) requires each employee in an excavation to be protected from cave-ins except when the excavation is entirely in stable rock or is less than 5 feet deep and a competent person finds no indication of a potential cave-in. Acceptable systems include sloping, benching, shoring, or shielding. Deeper excavations have additional design rules, but 5 feet is the general trigger.
8Immediately before placing concrete for metal-building piers or continuous footings, the subgrade should be:
A.Proof-rolled or otherwise checked so loose, organic, or pumping material is removed and the bearing surface matches the soils report
B.Flooded overnight so the soil is fully saturated
C.Covered with loose topsoil to cushion the concrete
D.Left uncompacted so rain can drain through the footing
Explanation: Foundation soils must provide the allowable bearing pressure used in the metal-building foundation design. Proof-rolling or probing finds soft, organic, or pumping areas so they can be undercut and replaced with compacted fill. IBC Chapter 18 requires footings on undisturbed soil or properly compacted fill; placing concrete on unsuitable subgrade can cause settlement and frame racking.
9How many cubic yards of concrete are required for a 54 ft by 30 ft slab that is 6 inches thick? Ignore waste.
A.20 cubic yards
B.27 cubic yards
C.30 cubic yards
D.45 cubic yards
Explanation: Convert thickness to feet: 6 in = 0.5 ft. Volume = 54 × 30 × 0.5 = 810 cubic feet. Divide by 27 cubic feet per cubic yard: 810 ÷ 27 = 30 cubic yards. On a real order, add the specified waste factor after this net quantity is calculated.
10A continuous footing for a metal-building wall is 24 inches wide, 12 inches thick, and 162 feet long. How many cubic yards of concrete are required? Ignore waste.
A.12 cubic yards
B.8 cubic yards
C.16 cubic yards
D.24 cubic yards
Explanation: Convert width and thickness to feet: 24 in = 2 ft and 12 in = 1 ft. Volume = 2 × 1 × 162 = 324 cubic feet. 324 ÷ 27 = 12 cubic yards. Isolated piers are calculated the same way and then added to any grade-beam or slab quantity.
