Planning and Design
A field survey is undertaken to identify the optimum route for the cable from the Origination to a location that is agreeable to all parties including stakeholders, property owners and local authorities and executable paths will be identified.
The field survey captures the proposed routing details, from where the line will go overhead to where it will be put underground, to routings and risers within buildings. The survey also identifies what permissions will be required along the route.
Similar kind of job will be done in desktop survey but later it will be given for validation by field team. The field / Desktop survey breaks down into three main areas:
- Mapping Overview of BOQs, wayleaves drawings, execution stages with red line and scope of works and time lines.
- Red line site pictures with field notes
- Project plan Proposal from ODC will be completed.
Strategic HLD (High Level Design) is produced according to a client Inputs on like admin boundaries, cluster build area, number of homes to be connected, UG / Aerial work routes, third party infrastructure, location of associated street furniture and other variables. At this point the cost & BOQs of delivering the design is calculated and included along with:
- A cluster Segmentation
- Proposal of Feeder Routes from the Points of Presence (POPs) to the breakout locations (ODC, Primary / Secondary Splitters, core site, Aggregate site, Mobility site etc.)
- A Single Line Diagram with Backbone Feeder Routes, Access points and Joint Locations from the HUB / POP’s /ODC to the breakout locations
- An HLD Drawing showing the construction type classification of all areas including red zone areas (Defense, Railway, Gas, Electrical lines areas)
- Total bill of Quantities (BOQs = BOM+BOS)
Once the strategic HLD has been validated, reviewed, evaluated with parameters like Homepasses / KM, cost / KM, cost /homepass, %age of connectivity, Build Capacity Vs Spare Capacity, Link Budget etc. are acceptable and agreed then project moves on to preparation of Design LLD (Low Level Design) which produces the next level of detail:
- Civil/ROL Drawings (Work / Wayleave Plans)
- Sub Ducting and Cabling Drawings (with Splice Locations)
- Splicing Drawings (Depicts types like Straight, Branch, Mid-Span)
- Fiber strand allocation sheets.
- Addressable Market List, along with suggested Drop Type for units
- Bill of Material
- Bill of Services
