Fiber project OSP civil works preparation

  Any fiber installation project is a major undertaking. Responsibility for the oversight of everything from detailed implementation plans to community relations, ensuring sufficient materials are ordered in a timely manner to safety and environmental concerns, means an intense amount of pre-work and ongoing coordination for the life of a project.

  Armed with this in information, a meticulous build plan (productivity for day, week, month, etc.) can be developed and the contractor can now ensure that the necessary equipment and resources are in place.
  Procedures and processes can now also be developed and put into place to ensure that the contemplated civil build is done to standards and executed within budget and timelines.

Pre-Build Procedures

  1. As an unfaltering believer in a pre-build survey: The verification of details contained in pre-build drawings, will ensure that potential problem areas are uncovered before the contemplated work kicks-off and potentially save one a lot of trouble later.
  2. Using the information available on the pre-build drawings, walk the pegged out route by foot, to determine the following:

  • Verify the soil classification/s by digging a pilot hole every 1km (hard, intermediate, soft)
  • If the soils or soil properties are not what were expected as noted in the contract, the client must immediately be consulted
  • Check and verify above and below ground utility locations
  • Note changes in gradient and/or direction
  • Identify all obvious landmarks where the route changes direction (take photos)
  • Take photos of all obstacles along the route
  • Verify HH / MH positions
  • Note road / rail crossings
  • Record crossings with other services
  • Record the presence of structures near the trench
  • Double-check the recorded details on the return journey
  • The route is typically marked using lime

Flagging PPE (Personal Protective Equipment) and Communication Preparation

1.  − A high-visibility reflective vest

       − A white hard hat

       − Steel-toed safety boots

       − Full length pants or coveralls – no shorts

       − During rainy weather, highly visible rainwear

2. When two flaggers are used, they can communicate verbally or visually if they are close enough to each other. It is desirable to appoint one of the flaggers as the coordinator. Where the end of a one-lane section is not visible from theother end, the flaggers must communicate via two-way radio. The safety of workers and the travelling public, while passing through the construction area, depends on the efficient actions of flag persons.

3. A Warning Flag Signal may also be used to warn a road user to proceed slowly, and be alert of a hazard in or adjacent to the roadway ahead.

4. A good, active flag person can be as effective as any othermeans of drawing attention to a hazard in the roadway.
