Subject: Consideration to Provide a SCADA Communications Link
1. WHY THIS MATTER IS BEFORE THE BOARD
Board approval is required for expenditures in excess of $15,000.
2. HISTORY
This project is an extension of the SCADA Enhancement Reliability Project, Phase 2.
This step involves building a microwave communication link between Red Mountain
Hydro (south side of Donner Lake) and Donner Lake Tank (north side of Donner
Lake). Fiber Optics were not landed at Red Mountain Hydro.
3. NEW INFORMATION
Red Mountain Hydro is located on the south side of Donner Lake. Due to its distance
from other district facilities, the cost estimate for a fiber optics installation would
exceed $80,000. Staff evaluated a microwave path study to assess the feasibility of an
alternate technology. The path study demonstrated that a microwave data link would
work well between Red Mountain Hydro and Donner Lake Tank. The data link would
support SCADA and security services from Red Mountain Hydro.
The map below illustrates the microwave data link.
Section 3.08.060 of the District code (Joint Purchasing with the State of California and
other public agencies) permits the District to take advantage of other agencies low
bids, providing that competitive procurement procedures were followed. The cost
proposal is submitted on The Interlocal Purchasing System (TIPS/TAPS), which
adheres to the District code. Alpha Omega, Inc. exists on the TIPS/TAPS vendor list.
4. FISCAL IMPACT
Sufficient funds exist in the FY13 Budget for the purchase and installation of a
microwave technology at Red Mountain Hydro in the amount of $22,461, plus a 10%
contingency, not to exceed $24,707, not including tax. The contract will include
microwave equipment and labor.
5. RECOMMENDATION
Award the SCADA Communication Link project to Alpha & Omega, Inc. in the amount
of $22,461, plus a 10% contingency, not to exceed $24,707, not including tax.
