FLS-W-21-01
Falls Water Company Application for Approval of Three Capital Projects
Data Request Response

Request No.: FLS-W-21-01 IPUC DR 16

REQUEST NO. 16: Please provide the detailed source information (vendor bids, cost
estimates, calculations, etc.) associated with each Estimated Cost in Exhibits 2 and 3 of
the Company's Application. Please include within your response the dollar amount for
each activity by vendor, specifically identifying activities performed by the Company and
any affiliated companies or individuals.
Response:
The cost estimates provided in Exhibits 2 and 3 of the Company’s Application are
engineering estimates provided by S&A Engineers. The estimates for the storage tank
and booster pump station and for the Taylor Mountain Well 2 well building from Exhibit 2
are entirely engineering estimates. The Exhibit 3 cost estimates for the storage tank
and booster pump station (repeat of cost estimate shown in Exhibit 2) and the 1,500
gpm well and pump station are also entirely engineering estimates.

The cost estimate for Well 11 and the pump station have some actual cost components.
The drilling of the well began in November 2020. The drilling was completed and test
pumped in April 2021. The test pump revealed that the well capacity is 2,500 gpm.
Copies of the two invoices are included in FLS-W-21-01 IPUC DR 16 Attachment 1
(Exhibit 4). The total cost to drill the well was $234,375.00.

FLS-W-21-01 IPUC DR 16 Attachment 2 (Exhibit 5) are copies of the cost
estimates/invoices from the following vendors:
 American Pump for the cost of the pumping equipment and column (excluding
electrical, plumbing, and concrete) for $182,790
 Rocky Mountain Valves & Automation, Inc. for part of some of the valves for
the well house piping for $7,240.82
 Ferguson Waterworks for pipe and fittings for the flow to waste line and pipe
from well house to existing distribution main and connection fittings to connect
to the existing main for $24,359.02.

Due to the system pressure issues caused by drought and hot temperatures, the
Company’s employees will work on Well 11 and complete items 11, 13-16. They will
also dig the footings for the wellhouse (portion of Item 6) and connect the pipes and

valves from the wellhead to the distribution main (portion of Item 9). Labor costs
associated with the Company’s employees completing these items and known materials
costs at the time of completing this response are listed below. Please see FLS-W-21-
01 IPUC DR 16 Attachment 3 (Exhibit 6) for Labor cost calculations.

that the Company’s employees will complete. The difference will be bid out to be

The remaining items on Well #11 project’s list will be put out for bid. Currently, the
engineering cost estimate is available for these items. The other projects listed in the
Company’s application Exhibits 2 and 3 have not begun and no bid process has been
done. The engineering cost estimates methodology for the storage tank and booster
pump station project, the Taylor Mountain Well #2 well house project, and the 1,500
gpm well as an alternative to the storage tank and booster pump station are shown in
FLS-W-21-01 IPUC DR 16 Attachment 4 (Exhibit 7) prepared by S&A Engineering.

Re: Methodology to Develop Recent Cost Estimates for Well 11 and Pump Station, Storage
Tank and Booster Pump Station at Well 9 Site, Future 1,500 gpm Well and Pump Station
and Well 2 Site and Pump Station Rehabilitation in the Taylor Mountain Water System

Dear Scott,

Per your request and pursuant to answering questions posed by the IPUC regarding our cost
estimates for the referenced projects, we give our methodology used to develop these cost
estimates. We describe the methodology first philosophically and secondly with details drawn
from the methodology.

Our cost estimating for these facilities is based on communications with pipe and equipment
suppliers, contractors, engineering subconsultants and knowledge and experience gained through
the engineering design process, which for me personally, now spans 29 years. I spend the bulk of
my effort on the high-dollar cost items and apply limited broad effort to the small dollar items as
they do not affect the bottom line near as much as the larger items. My experience includes
dozens of pump stations and a sufficient number of storage tanks that helps me make good
assumptions and estimates of construction of the unique facilities we plan for and engineer. Little
that we do is “cookie-cutter” that easily lends itself to using nationally produced cost estimate
tables or software that is constantly outdated, costly to purchase and perhaps not specific enough
to adequately describe the uniqueness of the facility. For instance, no nationally produced cost
table can predict the cost of drilling a well in the Snake Plain Aquifer better than those drillers
locally who have done regularly.

The specifics of my methodologies are my own and can only be described generally. But
experience has refined my process sufficiently to satisfy nearly all client types. My engineering
estimates are typically accepted, without undue questioning, by private owners, municipalities,
self-governed private water corporations, other branches of Idaho State government (Idaho
Department of Commerce, Idaho Division of Public Works, and Idaho Department of Water
Resources and DEQ) and agencies of the federal government (US Army Corps of Engineers &
USDA-Rural Development).

I will now describe, on a per item basis, how my personally developed methodology was applied
to these cost estimates being questioned by the IPUC to these future facilities.

Page 2

Item 2 – Well 11 is now drilled so the cost is the actual cost.
Item 3 – Mobilization covers a general contractors management, bonding, mobilization of
equipment and demobilization and cleanup at end of project. Five percent of the other items were
applied to calculate this.
Item 4 – This item was priced with support from a pump supplier and installer then contractor
overhead and profit was applied.
Item 5 – A generator supplier assisted me with sizing and costing for equipment delivery. I then
applied a markup to include installation and troubleshooting.
Item 6 – A reasonable unit price was applied to obtain the cost of the structural shell and
finishes.
Item 7 – Experience and the help of an electrical engineering subconsultant was obtained.
Item 8 – Experience based on other new installations was applied.
Item 9 – I listed out the piping, valves and misc. sensors and small components in a spreadsheet
and applied a cost to each based on phone call with material supplier, summed them, then
applied a markup for labor.
Item 10 – I obtained equipment suppliers cost for delivery and added a markup for installation.
Item 11 – An estimate was used for removal of topsoil, then the pit-run fill amount was
calculated at the local cost per unit by consulting with a general contractor. The same method
was used for the crushed aggregate material needed for the final grading.
Item 12 – A unit price was applied by consulting with a local concrete contractor and examining
recent bid results on my own projects.
Items 13-15 – A unit price was used that fits the effort to bury these lines and construct the
unique facilities associated with each.
Item 16 – This is the typical cost to install a tee and valve into an existing mainline.

FWC Storage Tank & Booster Pump Station at Well 9
Item 1 - na
Item 2 – Mobilization covers a general contractors management, bonding, mobilization of
equipment, demobilization and cleanup at end of project. Five percent of the other items were
applied to calculate this.
Items 3&4 – these were estimated based on other projects where vertical turbine pumps had to be
removed from the well, worked on, then reinstalled. The majority of the cost is labor and
equipment.
Items 5&6 – I listed out the piping, valves and misc. sensors and small components in a
spreadsheet and applied a unit cost to each based on a phone call with material supplier, summed
them, then applied a markup for labor.
Item 7 – We used our knowledge of storage tank costs, consulted a local tank supplier who has
recently built similar sized tanks in Eastern Idaho.
Item 8 – General knowledge and experience was applied.
Item 9 - This item was priced with support from a local pump supplier and installer then
contractor overhead and profit was applied based on experience with similar installations.
Item 10 – I listed out the piping, valves and misc. sensors and small components in a spreadsheet
and applied a cost to each based on phone call with material supplier, summed them, then
applied a markup for labor.
Item 11 – A reasonable unit price was applied to obtain the cost of the addition to the existing
pump station. This is a masonry block building.

Items 12&13 – Experience, the use of past bid results and the help of an electrical engineering
subconsultant was obtained.
Item 14 – Estimated based on experience.
Item 15 – This will be an addition to an existing SCADA link so less hardware will be required.
Items 16&17 – An estimate was used for importing and placing pit-run fill amount was
calculated at the local cost per unit by consulting with a general contractor. The same method
was used for the crushed aggregate material needed for the final grading.
Item 18 – A unit price was applied by consulting with a local concrete contractor and examining
recent bid results on my own projects.

FWC 1,500 gpm Well 11 & Pump Station (Exhibit B in Tank vs Well Memo)
Item 1 - na
Item 2 – This is the same cost as the actual cost of Well 11. For a 1,500 gpm well within the
FWC service area, the casing size will be the same as Well 11 (16” dia) and the drilling depth
will be the same due to the nature of the aquifer. All the other drilling steps to complete the well
are the same: surface seal, screen (size could vary a little), K-packer, development (could be
more on a same size well of lesser production), test pumping (could be incrementally higher for a
higher production well), and water quality testing. FWC was fortunate to get 2,500 gpm
production rate out of Well 11. But for budgeting and planning, as is the case here, it would not
be prudent to plan on that.
Item 3 – Mobilization covers a general contractors management, bonding, mobilization of
equipment and demobilization and cleanup at end of project. Five percent of the other items were
applied to calculate this.
Item 4 – This item was priced with support from a pump supplier and installer, then contractor
overhead and profit was applied. Support was also obtained by looking at the completion cost of
a recent similar well.
Item 5 – We examined the cost of a similar sized installation and called a generator supplier for
budgetary insight. We then applied a markup to include installation and troubleshooting.
Item 6 – A reasonable unit price was applied to obtain the cost of the structural shell and
finishes. The size of the building was also adjusted downward (compared to Well 11).
Item 7 – Experience and the help of an electrical engineering subconsultant was obtained.
Item 8 – Experience based on other new installations was applied.
Item 9 – I listed out the piping, valves and misc. sensors and small components in a spreadsheet
and applied a cost to each based on phone call with material supplier, summed them, then
applied a markup for labor.
Item 10 – I obtained equipment suppliers cost for delivery and added a markup for installation.
Item 11 –We used the same cost calculated for Well 11 as this well would be placed on a similar
site with some fill requirements to finish the well head a few feet higher than surrounding
ground.
Item 12 – We used the same cost calculated for Well 11 as this well would be placed on a similar
site. This is a projected future well on an unknown site so this cost merely acknowledges that
some site concrete will be required, but unknown at this point.
Item 13- A much lower number compared to Well 11 was used for this cost. We assumed our
discharge point was much closer to the pump station than for Well 11. Actual conditions are
completely unknown until a site is located.
Item 14-16. These are typical costs for pump stations and are small costs relatively. We used the
same costs here as in the Well 11 cost estimate.
