Anchor Bolt Cage Assembly and Tying Reinforcing Steel

In line with our goal of supporting transmission line construction, we assemble reinforcing steel cages for transmission and substation projects. We can build rebar cages, from large 345 kV monopole foundations to small control house slabs. However, where we really shine is assembling full-length anchor bolt cages for transmission lines.

Material Management and Logistics

Our material management and logistics services help bridge the gap between the design, procurement, and construction phases of transmission line projects, providing a smoother transition and, ultimately, reducing wasted time and money by:

  • Assisting with a Review of the Design to Develop a Material Takeoff List
  • Reviewing and Evaluating Bids to Help Determine Which Is the Best One for Your Company
  • Receiving, Unloading, and Inventorying
  • Kiting/Pre-Assembling Components
  • Staging/Shipping/Pole Location Drop Delivery
  • Providing Records Management and Reporting to Fit Your Needs

Stranded Asset Recovery

If you’re like most companies, you have a “boneyard” or some area where extra materials get dropped off for long-term storage. While you may have a general idea as to what materials are being stored, odds are there isn’t an accurate accounting of the quantity of these materials in storage. Our stranded asset recovery services can help with:

  • Identifying and Inventorying Stranded Assets
  •  Organizing These Assets
  • Providing a Current List of Usable Materials and a Map of Where They are Located in Your Facility
