Services Overview
Four Core Disciplines
A focused service offering built for mission critical environments, fast-moving scopes, and clean field execution.
02
Wire & Cable Pulling
Large conductor pulls, tray and conduit routing, and field coordination.
03
Testing & Commissioning
Pre-energization verification, acceptance testing, and turnover reporting.
04
Terminations & Splicing
Documented MV and LV terminations, splice restoration, and quality review.
Service 01
Medium Voltage Work
Cable installation, switchgear support, and energized environment operations for mission critical infrastructure. Our crews are trained and equipped for medium voltage scopes that demand precision and strict NFPA 70E safety compliance.
Execution Lens
Built for outage-sensitive scopes where planning and safety discipline matter as much as the install itself.
Crews arrive with the credentialing, documentation habits, and field controls these environments demand.
01
Scope Includes
MV cable systems (15kV-35kV)
Switchgear & transformer support
Energized work under NFPA 70E protocols
Outage coordination & execution
Duct bank & conduit pathways
Scheduled outage & shutdown support
Service 02
Wire & Cable Pulling
Large-scale pulling operations across data centers, industrial facilities, and commercial infrastructure projects. We manage the full pull - from reel handling and equipment setup to tension monitoring, documentation, and final inspection.
Execution Lens
Large pulling operations benefit from coordination before the first reel is touched, not after problems appear.
Routing, tension control, and reporting are treated as part of the scope, not post-job cleanup.
02
Scope Includes
Large conductor pulls (4/0 AWG and above)
Feeder cable installation in tray & conduit
Multi-trade pull coordination & scheduling
Pull tension monitoring & documentation
Data center raised floor & overhead cable routing
GC-integrated field execution
Service 03
Testing & Commissioning
Pre-commissioning, acceptance testing, and field verification on electrical systems before energization. We deliver structured, documented testing aligned with project specifications and owner standards.
Execution Lens
Verification is organized around owner confidence, not just a pass/fail event at the end of the job.
Testing and documentation stay connected so turnover does not become a separate rescue effort.
03
Scope Includes
Pre-commissioning & acceptance testing
Insulation resistance (Megger) testing
Hi-pot & VLF cable testing
Switchgear & relay testing
Pre-energization system verification
NETA-aligned acceptance testing & reporting
Turnover documentation packages
Service 04
Terminations & Splicing
Precision termination and splicing of medium and low voltage cables in mission critical environments. Every termination is executed to manufacturer specifications, documented, and verified before handoff.
Execution Lens
Connection quality is treated as a visible representation of the crew's discipline and handoff standards.
Labeling, documentation, and pre-inspection review help reduce closeout friction later in the project.
04
Scope Includes
15kV-35kV heat shrink & cold shrink terminations
MV splice kits & restoration
Low voltage panel & device terminations
Cable splicing & restoration
Termination documentation & labeling
Pre-inspection quality review
As-built termination records
Credibility
Built for Scope-Critical Execution
A field model designed for technical scopes where precision, pace, and handoff quality matter.
Service Fit
The value is not just what MCSS can do, but how tightly the crews, process, and documentation align around those scopes.
4 disciplines
Scope-specific staffing rather than generic labor coverage.
Foreman-led execution with documentation built into the workflow.
01
Specialized 4-service focus
02
Field-ready workforce
03
Documentation-driven turnover
04
Safety embedded in execution
