Aerial & Underground Construction
TRC Construction's "Aerial & Underground Construction" services encompass a comprehensive range of infrastructure development, specifically focusing on the installation and maintenance of utility lines, communication networks, and power systems, both above and below ground.
Aerial Construction:
This refers to all work performed above ground, typically involving the installation and maintenance of lines on utility poles.
Pole Line Work:
Tailored Network and Infrastructure Designs: This is the cornerstone. Instead of a one-size-fits-all approach, they analyze your specific operational demands, current technology landscape, and future goals to design a system from the ground up. This involves:
- New Pole Installation: Setting new utility poles to extend networks or replace damaged ones. This includes site preparation, drilling holes, and securing the poles.
- Pole Transfers: Moving existing lines and equipment from old poles to new ones, often during pole replacement projects.
- Overhead Cable Installation: Stringing new power lines, communication cables (fiber optic, coaxial, copper), and other aerial infrastructure between poles. This involves specialized equipment like bucket trucks and line pullers.
- Hardware and Equipment Installation: Attaching transformers, switches, insulators, streetlights, and other necessary equipment to poles.
- Maintenance and Repair: Inspecting, repairing, and upgrading existing aerial infrastructure, including storm damage repair, wire sagging correction, and equipment replacement.
- Make-Ready Work: Preparing poles for new attachments by ensuring there is sufficient space and structural integrity, often involving coordination with multiple utilities.
Underground Construction:
This involves all work performed beneath the surface to install and maintain buried infrastructure. This approach is often favored for aesthetics, safety, and protection from weather.
Trenching:
- Excavation: Digging open trenches using specialized equipment (trenchers, excavators) to create pathways for conduits, cables, and pipes.
- Backfilling and Restoration: After installation, refilling the trenches and restoring the surface to its original condition, which can include paving, landscaping, or concrete work.
- Site Preparation: Clearing the area, marking utility lines, and ensuring the ground is safe for excavation.
Boring (Directional Drilling/Horizontal Directional Drilling - HDD):
- Trenchless Technology: A method of installing underground pipes, conduits, and cables without digging a continuous trench. This is particularly useful for crossing roads, rivers, existing infrastructure, or environmentally sensitive areas.
- Pilot Hole Creation: Drilling a small pilot hole along the planned path.
- Reaming: Enlarging the pilot hole to the required diameter.
- Product Pullback: Pulling the conduit or pipe through the enlarged bore hole.
- Benefits: Minimizes surface disruption, reduces restoration costs, and often provides a faster installation method in certain scenarios.
Conduit Installation:
- Protection: Laying protective pipes (conduits) made of materials like PVC, fiberglass, or steel within trenches or boreholes. These conduits house and protect electrical cables, fiber optic lines, and other sensitive infrastructure from environmental factors and physical damage.
- Splicing and Pulling Chambers (Manholes/Handholes): Installing access points (manholes or handholes) at regular intervals or at strategic locations for future maintenance, splicing, and cable pulling.
- Duct Bank Construction: Creating an organized system of multiple conduits encased in concrete, often used for major underground utility arteries.
