Tapping into a renewable natural gas project for the first time, Interstates recently worked with Gevo to build a central biogas purification site and connect it to three different dairies in Northwest Iowa. Interstates provided Gevo with power distribution, PLC design and construction, programming, instrumentation, and heat trace work.
Electrical Remediation Process: Phase 1 - 5 ►
Implementation Phase(s)
Planning Phase(s)
Phase 1: Framework
Phase 2: Concept Design
“Issue for Bid” or “Issue for Construction” packages. Assistance through the bidding and contractor selection process. Phase 3: Detailed Engineering
Our scope involvement during this phase varies widely depending on the client’s needs and project delivery method, from full- time onsite construction assistance to simply some periodic site observation and phone support. Phase 4: Construction Phase
Phase 5: Wrap-Up
Site Visit and Meetings with plant personnel. Determine Scope boundaries of the electrical remediation effort. Master plan framework report. Planning to maximize the effectiveness of plant downtime. Engineering Fee Proposal for Phase 2. Phase 1 Cost Range: $5,000 - $20,000
Provide Conceptual Engineering. Multiple option sketches for possible solutions. Collaboration with Electrical Vendors and Contractor. Review options with Client. Details added to selected option. Break out overall effort per electrical area/system. +/- 25% Construction Cost Estimate. Client able to request funds for overall project. Phase 2 Cost Range:
Wrap-up and final documentation of the new power distribution system, usually along with an updated arc flash study. System training and final walk-through by engineering team. Confirm project goals were achieved.
$5,000 - $75,000 (1-2% of overall)
Determine project delivery method. See note below.
On small remediation efforts (total capital cost < $250,000), Phase 1 & 2 are often combined.
Phase 3 & 4 are combined for design-build. If design-bid-build, the phases remain separate.
