Compare proposals against one written scope. Differences in included work often matter more than the difference in the quoted total.

Build a comparison sheet

Use rows for routes, cable type, strand count, panels, connectors, splicing, patch cords, equipment, power, testing and records. Add pathway work, lifts, permits, restoration and working hours. Mark each item included, excluded or unclear for every bidder. Resolve unclear items in writing.

Compare assumptions

Ask how obstructed routes, inaccessible spaces and undocumented existing fiber will be handled. Identify unit rates or a change process for work that cannot be quantified before survey. Confirm which quantities are estimates and what measurements support them.

Review acceptance and support

Require the same test and handover deliverables from each bidder. Compare specific warranty coverage and exclusions. Ask who handles a service request and what information is required. A broad promise of reliable service is not a measurable commitment.

Record the decision

Keep the accepted scope, clarifications and changes together. Document why the selected proposal meets the project requirements. Before work starts, confirm the route, access arrangements and person authorized to approve changes.

Compare contractor scopes fairly

Two fiber proposals can use the same strand count yet include different trenching, conduit, splice enclosure, restoration or testing assumptions. A comparable bid should identify the start and termination points, pathway ownership, cable rating, closure type, labor access, permit dependencies and warranty exclusions. Require contractors to state whether switches and transceivers are included.

Define the acceptance evidence

Specify endface inspection, loss measurement, OTDR use where appropriate, strand labeling and delivery of test reports. Tie change orders to documented unexpected conditions, such as blocked conduit or damaged existing fiber. A low price is not necessarily lower lifecycle cost when as-built documentation and future service are omitted.
