Capabilities
What we build, power and keep running
Towers, fiber, DC power, electrical and solar, plus the testing that proves the work holds. All of it done by DSG crews.
Wireless Infrastructure
Everything that makes a wireless site work, from the foundation to the radio at the top. DSG crews build and integrate macro and small cell sites, install distributed antenna systems inside buildings, and align microwave backhaul for rural and temporary links. The steel itself is climbed, inspected and repaired by DSG technicians under a "Safety First" philosophy: every one of them is trained in tower safety and rescue.
Scope
- Macro Cell 4G/5G Engineering, Procurement & Integration
- Raw land builds and tower stacking
- Micro Cell Engineering, Procurement & Integration
- Small Cell: project management, construction, installation, power/batteries & UPS, RF & fiber installation, PIM & RF testing, commissioning
- DAS: design, development, commissioning, repair
- C-RAN: site audits, DC plant engineering, live site re-work (hot slides), radio/router/MUX installations
- Antennas & line installations; dish alignments, installations and removals
- Microwave: turnkey point-to-point builds, 1ft to 12ft dishes, pathing and alignment
- Site surveys, tower mapping, post mount inspections (PMIs), re-lamps
- Steel and mount modifications; full mount replacement
- Cellular RF system installation, maintenance and repair; RF jumpers; sweep & PIM testing
Fiber Infrastructure
High-capacity fiber for carriers, wireless networks, utilities and enterprise, taken the whole way: route planning and permitting first, then trenching, micro-trenching, directional boring and aerial placement, then the precision work that decides whether the route actually performs: fusion splicing, OTDR testing and network certification. Maintenance and emergency restoration run 24/7 once the route is live.
Scope
- Fiber network construction: trenching, micro-trenching, directional boring, aerial placement, underground deployment
- Wireless tower backhaul for 5G tower infrastructure, small cells and edge network expansion
- Certified fusion splicing, OTDR testing and fiber network certification
- Network engineering: route planning, permitting and carrier-grade network design
- Turnkey fiber projects, from planning and engineering to construction and final network activation
- 24/7 fiber maintenance and emergency restoration
- Structured cabling (power, Ethernet and fiber)
Critical Power & Generators
The oldest work in the group: Direct Power was established in 1994. DC plants, stationary batteries, rectifiers, inverters and standby generators, engineered, furnished and installed as turnkey systems, then maintained for the life of the asset. Full-time DC power service crews operate throughout the Southeast and are on-site within hours of notice for emergencies, 24/7, 365 days a year.
Scope
- DC plant engineering, furnishing & installation; new turnkey systems; upgrades; hot cut-overs; test & turn-ups
- DC plant rectifiers & controllers; fuse & breaker panels; distribution and expansion
- Stationary battery: power assessments, installation, upgrades, replacement, servicing, recycling, monitoring, preventive maintenance
- Generator replacement: licensed and qualified for turnkey generator replacements
- Inverter power systems: installation and maintenance
- Turnkey power solutions: emergency standby generators, AC to DC rectifiers, DC to AC inverters, AC and DC switch panels, breaker distribution bays, surge suppression, EV charging stations
- Emergency services: battery/UPS servicing, equipment replacement, temporary batteries or power plants, factory certified repairs, alarm testing and reset
- Spill containment kit installation and maintenance
- Battery monitoring: certified by battery monitoring OEMs to service, install and use monitoring 24/7
Electrical Services
DSG is a fully licensed electrical and general contractor, so the electrical scope stays with its own crews. The work runs from pre-construction assistance through pad and transformer installation, complete electrical build-outs and wire management, to testing, commissioning and site clean-up. The team has been involved in 500MW+ of installations, and has completed the electrical installation, DAS/SCADA and commissioning of 150MW+ of turnkey projects with its own people.
Scope
- Pre-construction assistance
- Pad installs and transformer installs
- Complete electrical build-outs and wire management
- Grounding services; earth and equipment grounding surveys
- Testing, commissioning and quality control, with reporting
- DAS/SCADA installation and commissioning
- Fiber installation and fusion splicing
- Site clean-up and site re-power
- Engineer, furnish & install (EF&I); development of procurement specs; as-built documentation and drawings
Solar & Energy Storage
Utility-scale and commercial renewable energy assets, from first commissioning to the day-to-day of keeping them producing. DSG commissions PV systems, runs operations and maintenance with NABCEP-certified and OSHA-trained technicians, installs and optimizes the DAS/SCADA that reports on them, and designs, procures and installs battery energy storage, backed by the 25+ years of battery experience the group built up on the power side.
Scope
- Operations & maintenance: scheduled, unscheduled and preventative maintenance, troubleshooting, emergency response
- Commissioning and testing to contractual and IEEE requirements, with complete O&M documentation and transition reports
- Energy storage: design, procurement and installation of customized battery energy storage systems; servicing and maintenance
- Monitoring: DAS design, installation and optimization; energy production review; system health analysis; dispatch prioritization
- SCADA/DAS system installations
- Engineering: PV system design, energy storage system design, repowering and upgrading existing systems, permit negotiations
- Site assessments: safety assessments, budget projections, component condition determination, construction audits, performance evaluations
- Aerial imaging and Drone IR inspections
- IV curve tracing 1000V/1500V, VOC testing, megger testing, power quality analysis
- Technical asset management; routine inspections of panels, wiring, combiners and inverters
Testing, Commissioning & Audits
Crews of engineers audit every job DSG runs, and take on assets DSG never built. The range runs from scope and method-of-procedure review to fully certified, reportable results in AC/DC power, load profiling, networking and grounding, using current test equipment. It is how a client knows the install performs the way it was specified to.
Scope
- Battery capacity & acceptance testing (IEEE 450 & 1188), pre- and post-test evaluations, temporary batteries provided
- ANSI / NETA maintenance testing
- Site audits customized to client requirements: facility condition, equipment inventory, load profile & run-time analysis, recommendations
- Internal resistance / conductance / impedance testing
- Connection integrity testing and ground resistance testing
- Infrared thermography; isolation & noise mitigation
- PIM, sweep and fiber testing; VSWR
- Post mount inspections (PMIs), mount mapping and site audits on tower assets
- IV curve tracing, VOC and megger testing on PV assets
- OTDR testing and fiber network certification
