Utility trenching on a data center site has zero margin for error. Misalign a single 30-inch fire main and you've delayed CO by weeks. Skip a thermal bedding spec and the EPC kicks the line back. Backwell self-performs utility trenching for data center construction across Central New York with crews who've installed thousands of feet of industrial utility on solar campuses, semiconductor sites, and commercial pads.
Trenching Scope We Handle
Wet Utilities
- Domestic water service , 6 in to 24 in PVC, ductile iron, HDPE
- Fire main , 8 in to 30 in service, looped systems, post-indicator valve installation
- Sanitary sewer , gravity main and force main, lift station tie-ins
- Storm sewer , RCP, HDPE, CMP up to 60 in diameter
- Industrial water service , process water, cooling water makeup
- Fuel oil , emergency generator fuel piping with secondary containment
- Glycol loops , for cooling system distribution
Trench Specs We Hit Routinely
- Depth: standard 4–6 ft, capable to 25 ft with proper shoring
- Width: 18 in to 8 ft based on spec
- Bedding: thermal bedding, sand, stone, or engineered fill per spec
- Compaction: ASTM D698 testing at every lift, 95% modified Proctor for under-road
- Backfill: native, engineered, flowable fill, or controlled low-strength material (CLSM) per spec
Conditions We Handle
- Rock excavation: mechanical breaking with high-capacity excavators and hydraulic hammers, no blasting
- Dewatering: pumps, well points, French drains for high water table sites , common in Oswego County and along Onondaga Lake
- Shoring: trench boxes, hydraulic shoring, sheet piling for deep trenches
- Wetland and stream crossings: timber matting, same-day backfill, NYSDEC compliance
- Frozen ground: winter trenching with proper heat and progressive backfill
Counties We Serve
Our utility trenching crews work across the eight Central NY counties within 90 minutes of our Syracuse equipment yard:
- Onondaga County , Syracuse, Clay, DeWitt, Liverpool
- Oswego County , Oswego, Fulton (hydropower corridor)
- Jefferson County , Watertown, Black River (NYPA hydropower)
- Oneida County , Utica, Rome, Marcy (semiconductor corridor)
- Madison County , Oneida, Canastota, Hamilton
- Cayuga County , Auburn, Weedsport
- Cortland County
- Wayne County (eastern)
Equipment Staged for Utility Trenching
- Cat 320 / 336 / 374 excavators
- Cat D6 / D8 dozers
- Articulated dump trucks
- Plate compactors and rammer compactors
- Roller compactors (smooth drum and padfoot)
- Hydraulic breakers (excavator-mounted)
- Trench boxes (4 ft, 6 ft, 8 ft)
- Pump systems for dewatering
- Laser-guided trench equipment
Compaction Testing & QA/QC
Every lift gets compaction testing per ASTM D698 (standard Proctor) or ASTM D1557 (modified Proctor) per spec. We coordinate with the EPC's third-party testing agency or carry our own ICC-certified testing technicians. Results are documented on the same day, with rework lifts done while equipment is on site.
Coordination with Other Trades
Utility trenching on a data center sequences against:
- Civil mass excavation (we self-perform) , utility runs into prepared subgrade
- Electrical trenching and ductbank (we self-perform) , water/sanitary stays clear of high-voltage runs
- Fiber trench (we self-perform) , separation from power and water
- Pad foundations and slab , utility laterals stub up before pad pour
- Site paving (typically EPC scope) , trenches backfilled and tested before final lift
We sequence our scope to minimize rework and conflict with the other trades on site.
Why Backwell
- Self-perform , utility trenching done by Backwell crews, not subcontracted
- Bonded , performance and payment bonding capacity
- Davis-Bacon / NY prevailing wage compliant , federal and federally-funded data center work in scope
- Women-Owned Small Business (WOSB) , federal designation
- SAM.gov registered , UEI XY4KWNPR6ES5
- Local equipment yard , Syracuse, central to all CNY data center sites

FAQ
What's your maximum trench depth?
25 ft with proper shoring. Standard data center utility runs are typically 4–6 ft deep; deeper runs (lift stations, force main routing under existing infrastructure) we handle with sheet piling or hydraulic shoring.
Can you handle rock excavation in trenches?
Yes. Mechanical breaking with high-capacity excavators and hydraulic hammers. No blasting required. Common in Jefferson and northern Oneida counties where limestone is shallow.
Do you handle thermal bedding for MV/HV trenches?
Thermal bedding is typically part of the electrical scope, but we install per spec when it's bundled with our utility trench package. We coordinate with the electrical sub on bedding specifications.
How do you sequence utility trenching against operating equipment?
We coordinate with the EPC's CM and the data center operator (when relevant for retrofit/expansion projects) to schedule trenching against operational windows. Two-shift operations are available when schedule requires it.
Can you handle the wetland and stream crossings common in Central NY?
Yes. Timber matting, same-day backfill, NYSDEC freshwater wetland compliance. We maintain on-site environmental staffing during disturbance phases and run all activities through approved SWPPP and SPDES permits.
