You are reviewing a building backbone design with a vertically aligned telecommunications room (TR). In the spec you note in a footnote with details that the slots at one end of the telecommunications room (TR) must be flush with the floor and the sleeves provide at the end of the telecommunications room (TR) must also be flush. In your meeting with the electrical engineering firm that has provided the spec, you make the comment that according to best practices, the MINIMUM that slots and sleeves must extend above the finished floor are:

• A.64 mm (2 1/2 in) for slots and 64 mm (2 1/2 in)
• B.25 mm (1 in) for slots and 25 mm (1 in)
• C.51 mm (2 in) for slots and 51 mm (2 in)
• D.25 mm (1 in) for slots and 51 mm (2 in)
• E.51 mm (2 in) for slots and 25 mm (1 in)

All of the following are considered market or regional conditions that can impact construction costs EXCEPT:

• A.Other large projects in the area
• B.Displacement and relocation
• C.Seasonal effects on construction costs
• D.Construction time frame

You have the responsibility of designing a railroad track crossing for an outside plant OSP cable. There are three separate railroad tracks to be crossed. The measurement between the center of the two outer tracks is 16 m (52 ft). Using the standard track width of 1435 mm (4 ft 8.5 in), what is the length of the rigid steel conduit required to facilitate the crossing?

• A.31 m (102 ft)
• B.25 m (82 ft)
• C.35 m (115 ft)
• D.40 m (130 ft)
• E.20 m (66 ft)

An outside plant (OSP) cable must be placed under a pipeline with two side by side pipe runs. The distance between the outside pipes is 6 m (20 ft). What is the length of the conduit required to facilitate the pipeline crossing?

• A.9 m (30 ft)
• B.7.6 m (25 ft)
• C.12 m (40 ft)
• D.10.7 m (35 ft)
• E.6 m (20 ft)

You are designing a horizontal pathway system where you will provide 100 mm (4 in) conduit and pull boxes.
The building architectural elements will only allow for a single layer of conduits (not stacked). The main horizontal pathway system consists of five 100 mm (4 in) conduits. Large single sheath copper cables are not expected to be placed. Which of the following is the MINIMUM width pull box that is to be provided?

• A.1520 mm (60 in)
• B.900 mm (36 in)
• C.1830 mm (72 in)
• D.600 mm (24 in)
• E.1220 mm (48 in)
