Clint and Kyle,
I have the following budget synopsis of the City of Meridian Well #8 abandonment project:
1) REHABII.ITATION OF THE WELL #$:
a. This project was originally conceived as a well rehabilitation project.
b. The idea was to rejuvenate the well to be used for irrigation of the Main Street
landscaping.
c. The budget and contract for the project were conceived from this scope of work.
d. A camera survey of the well showed the walls of the well were thickly encrusted so that
the condition of the casing could not be inspected.
e. As part of the rehabilitation, McLeran Well Drilling scraped and wire-brushed the casing
walls.
f. A re-inspection by camera, with the encrustation removed, showed the casing was
severely corroded with many corrosion holes.
g. Indeed, large volumes of sand were entering the well as McLeran tried to bail the well.
h. We concluded the well was ruined and recommended that the City change .from a
rehabilitation project to an abandonment project.
i. The work accomplished by McLeran for the rehabilitation is a prerequisite for the
abandonment so no time was lost there.
j. With McLeran having to deal with the caving sands, the rehabilitation project budget of
$12,400 was exceeded by $3,412.50.
k Total cost of the scraping, brushing, and bailing portion of the project is $15,812.50.
L McLeran did a fine job of this work and his invoice is approved by HLI for payment.
m. McLeran was paid the amount of his original contract ($12,400) so he is currently owed
$ 3,412.50
Z) ABANDONMENT OF THE WELL #$:
a. McLeran moved into the abandonment job after a significant hiatus of the City deciding
what to do with this well.
b. Owing to the length of time between jobs, McLeran had to move his rig off and back on
so we incurred another mobilization fee ($2,500).
c. The abandonment work progressed without incident taking only about 20 hours at very
reasonable cost.

d. The materials bill, however, was substantial ($ 18,830) owing to the hole taking 38 cubic
yards of bentonite grout to seal the well.
e. Because 27 cubic yards should have filled the hole, we know that a 10 cubic yard void
space was present behind the well casing.
f. The grout overage totaled $ 5,000 by itself.
g. Total cost of the abandonment part of the project is $ 25,572.50.
h. McLeran performed this work very well for the City and his invoice is approved by HLI
for payment.
i. The well is properly plugged and no longer serves as a liability to the City or the water
resource.
3} BUDGET ANALYSIS:
Initial scraping, brushing, and bailing = $ 15,812.50
- Invoice No 1 and payment by City - $12 400 00
Balance owed to McLeran = $ 3,412.50
Abandonment cost = $ 25,572.50
Balance due McLeran = 3 412.50
Total amount due McLeran $ 28,985.00
Total project cost = $ 41,385.00
- Previ®uS ,~aytx~ent to McLeran = y _ $12 400 00
Total amount of change order = $ 28,985.00
