The Anchorage Water and Wastewater Utility (AWWU, Utility) is soliciting proposals
from qualified firms to provide professional services for the Girdwood Water Storage
Tank Site Selection project. The project will identify a location to construct a second
water storage tank in Girdwood, Alaska.
1.2 Background
Girdwood is a small community within the Municipality of Anchorage. New
developments in the community will substantially increase the number of residences.
To accommodate the increase in residences, ensure resiliency within the water
system, ensure required minimum fire flows, and ensure sufficient treatment time for
water, a new water storage tank is necessary. A new water storage tank will also
provide system resiliency that will allow for the existing water storage tank in
Girdwood to be maintained without affecting water service to the community. This project will recommend a site for a new water storage tank for Girdwood. The
project will also lay the groundwork for AWWU to acquire the recommended property.
3.2 Project Tasks
Work under this proposal may include but not be limited to, hydraulic analysis,
engineering analysis of benefits and detriments of potential sites, analysis of real
property with respect to ease of purchase, evaluation of pipe alignment from the
existing [or new] Girdwood well to water storage tank and connection to the existing
pipe infrastructure, surveying, permitting, soils exploration and reporting at the
desktop level with no field exploration required, and real estate acquisition services
as additional services to the contract.
Work may include but is not necessarily limited to, the following:
A. Review of existing hydraulic model, plans, studies, technical memoranda, records
drawings, and any other data relevant to the project.
B. Provide a Project Management Plan within fourteen (14) calendar days of Notice
To-Proceed. AWWU at its option may change the scope of services.
C. Solicit input from stakeholders including: AWWU Treatment, Engineering, and
O&M divisions, and others as needed.
D. Prepare a Design Study Report that identifies potential sites for a new water
storage tank for Girdwood. This Design Study Report shall include a
recommended site and will serve as the basis for a future design by AWWU.
Elements to include: a. Analysis of topography to identify sites what will provide hydraulic
advantages.
b. Hydraulic modeling of the sites to determine improvements to the existing
water system.
c. Sizing of the water storage tank to accommodate the current and future
needs of the community with respect to population and fire protection.
d. Analysis of soil conditions at the selected sites.
e. Determination of the appropriate type of water storage tank that is best
suited to the potential sites.
f.
Analysis of land ownership of the sites and property in between the well
and water storage tank and ownership and/or permitting issues that may
be associated with construction of the tank and the feed and return
transmission mains. Potential selected sites should not be prohibitively
landlocked by issues related to property ownership.
g. Analysis of alternative alignments for fill and return transmission mains to
the selected water storage tank sites.
h. Analysis of the level of environmental permitting process that will be
required for the selected sites and transmission main alignments.
i.
j.
Determine land and easement acquisitions necessary to install the water
storage tank and associated transmission mains.
Provide preliminary cost estimates to construct a water storage tank and
feed and return transmission mains to the selected sites.
E. Additional Services: AWWU may include additional services relevant to this
project. Examples of such services may include, but are not limited to, surveying
and preparation of property and easement acquisition maps and metes and
bounds descriptions of the acquisitions. Right-of-way property acquisition
services to prepare all necessary documents needed to acquire the
recommended property. Assist AWWU with purchasing the identified
recommended properties. Question Deadline 09/26/2024 at 12:00 PM AKT For further information contact Purchasing at (907) 343-4590 or email wwpur@muni.org. All correspondence should include the RFP number and title.
