OSP Codes Compliance & Project Documentation 4 — Questions and Answers
Question 1: A Section 106 review under the National Historic Preservation Act is triggered when an OSP project:
- Crosses a state highway
- Involves federal undertakings that may affect historic properties (Correct answer)
- Exceeds $1 million in construction cost
- Requires a NEPA environmental impact statement
Correct answer: Involves federal undertakings that may affect historic properties
Section 106 requires federal agencies to consider the effect of their undertakings on historic properties, including federally funded or licensed OSP projects.
Question 2: In OSP documentation, 'station numbering' or 'chainage' refers to:
- The number of cable pairs in a binder group
- A distance-based coordinate system used to locate features along a route (Correct answer)
- The sequential numbering of splice cases
- Customer service order tracking numbers
Correct answer: A distance-based coordinate system used to locate features along a route
Stationing or chainage assigns incremental distance markers along a route, enabling precise location of buried infrastructure features on plan drawings.
Question 3: Which permit is typically required from the Army Corps of Engineers for OSP work that involves crossing or disturbing navigable waterways?
- Section 9 Permit
- Section 404 / Section 10 Permit (Correct answer)
- Section 7 Consultation
- Section 106 Review
Correct answer: Section 404 / Section 10 Permit
Section 404 of the Clean Water Act and Section 10 of the Rivers and Harbors Act (enforced by the Army Corps) govern discharges and structures in navigable waterways.
Question 4: A telecommunications project's 'record drawings' differ from 'design drawings' in that record drawings:
- Are created before construction begins and show intent
- Reflect actual installed conditions verified after construction (Correct answer)
- Are only used internally and not submitted to clients
- Show only underground facilities, not aerial plant
Correct answer: Reflect actual installed conditions verified after construction
Record drawings (as-builts) are updated after construction to document what was actually installed, including any deviations from the original design.
Question 5: Under NESC Table 235-1, aerial communication cables must maintain minimum vertical clearance above roadways used by trucks. What is the typical minimum clearance?
- 12 feet
- 15.5 feet
- 18 feet (Correct answer)
- 22 feet
Correct answer: 18 feet
NESC requires a minimum 18-foot vertical clearance above roads accessible to trucks for communication cables under Grade C construction.
Question 6: A project manager issues a Request for Information (RFI) during OSP construction when:
- Equipment has arrived on site and needs inspection
- There is ambiguity or missing information in the contract documents (Correct answer)
- A subcontractor submits their final invoice
- A safety incident must be reported to OSHA
Correct answer: There is ambiguity or missing information in the contract documents
An RFI is a formal process used to seek clarification from the designer or engineer when contract documents are unclear, incomplete, or conflicting.
Question 7: In joint-use pole attachments, the 'transfer' of an existing cable to a new or replaced pole is documented in which project record?
- OTDR test report
- Make-ready work order or transfer order (Correct answer)
- Fiber acceptance test plan
- Zoning variance application
Correct answer: Make-ready work order or transfer order
Make-ready or transfer work orders document the movement of existing facilities from old poles to replacement poles before or during new attachment work.
