Construction & Infrastructure Contractors
Prime contractors, EPC firms, and project managers do not have time to babysit a specialty sub. CoreSync takes the fiber splicing and testing scope off your list with a documented crew, a named lead, and records that survive closeout.
Fiber Is a Small Line Item That Can Hold Up the Whole Job
On a large infrastructure project, fiber splicing is a small slice of the contract value and a large slice of the risk. The cable gets pulled, the closures get set, and then the work sits idle until someone qualified can splice and test it. If that someone is late, the energization date, the turnover date, or the final payment slips with them, and the general contractor carries the explanation.
Most primes do not want a full-time fiber department for a handful of scopes a year. They want a specialty subcontractor that reads the spec, shows up when the conduit and cable are ready, and works inside the project's safety and reporting structure without constant direction. The failure modes are familiar: crews that arrive without cleared paperwork, loss results nobody can find at closeout, and as-builts reconstructed from memory weeks after demobilization.
CoreSync is built around avoiding those three problems. We handle the splicing and testing as a defined scope, keep our documentation current as segments finish, and hand your project manager a closeout package that supports the pay application instead of delaying it.
What CoreSync Provides
- Fully documented fiber splicing and testing as a specialty subcontractor
- Crew mobilization timed to your schedule, without delays
- Insurance, bonding, and safety documentation on request
- Coordination with project managers, supervisors, and site engineers
- Clean, complete as-built documentation for closeout packages
- Segment-by-segment test records that support pay applications
A Fiber Specialty Scope That Fits Inside Your Project
Splicing & Termination Scope
Fusion splicing, closure and panel termination, and tray organization carved out as a defined scope, so your self-perform crews stay on placement, trenching, and civil work.
Acceptance Testing
Bi-directional OTDR traces and insertion-loss readings recorded against the spec in your contract documents, ready for the owner's representative to witness or review.
Schedule-Driven Mobilization
Crews staged against your look-ahead schedule and sequenced behind your cable pull, so the splice window opens when the plant is ready and not a week later.
Paperwork Before the Gate
Certificates of insurance, safety program, crew rosters, and site orientation records delivered ahead of mobilization instead of chased after the first rejected badge.
Single Point of Contact
One lead who talks to your superintendent daily, reports production against plan, and flags a closure count or access problem before it becomes a delay claim.
Closeout-Ready Records
Splice matrices, tray maps, and trace files organized by segment and handed over as the work finishes, so the O&M package is not assembled from memory at the end.
From Subcontract Award to Closeout Package
Review the Contract Scope
We read the splice and test requirements in your subcontract and drawings first: fiber counts, closure types, loss limits, and who owns what at the handoff to the next trade.
Mobilize to Your Site Rules
Crews arrive oriented to your safety plan, with the insurance and credential paperwork already cleared, equipment calibrated, and a named lead on the ground.
Splice and Test in Sequence
Work follows your cable pull and closure placement. Each completed segment is tested before we move on, so rework is caught while crews are still on site.
Deliver the Closeout Package
Test results and as-builts are submitted segment by segment, which keeps pay applications supportable and the final turnover free of documentation scrambles.
Primes, EPCs, and the Trades Around Them
Whether fiber is the whole contract or one line in a much larger scope of work, the same rules apply: the crew has to be cleared to work, the results have to be traceable to a specific segment, and the records have to be ready when the owner asks for them. We work with the party holding the contract and take direction from the people running the site.

Frequently Asked Questions
What do you need from a prime contractor to price a splicing scope?
The fiber counts and cable types, the number and style of closures and panels, the loss limits in the specification, the site access rules, and the target window. Drawings and the relevant subcontract exhibits are enough for a first price.
Can you provide insurance and safety documentation before mobilizing?
Yes. Certificates of insurance, our safety program, crew rosters, and any site-specific orientation records can be delivered ahead of mobilization so badging does not hold up the start date.
How do you coordinate with the other trades on a job?
We work from your look-ahead schedule and report to your superintendent or project manager. Splicing follows cable placement and closure installation, and we flag access or sequencing conflicts early rather than waiting for the weekly meeting.
What does your closeout documentation include?
Splice matrices, tray maps, bi-directional OTDR trace files, and insertion-loss results organized by segment, delivered as each segment finishes so they can support your pay applications and final turnover.
Do you take small scopes, or only large projects?
Both. A single closure repair inside a building project and a multi-month backbone splice scope are handled the same way: defined scope, documented crew, and records delivered to the standard in your contract.
