<br />
<br />.
<br />
<br />2, Reconstruct existing darn embankment, construct new outlet structure and spillway and
<br />dredge reservoir to a capacity of 1,200 acre-feet.
<br />3. Reconstruct existing darn embankment, construct new outlet structure and spillway and
<br />dredge reseIVoir to a capacity of 1,750 acre-feet.
<br />
<br />Alternatives No.1 - was unacceptable, since it only maintained the existing capacity of the reseIVoir and
<br />did not allow the Company to exercise its full water right. Bid Cost = $936,318
<br />
<br />Alternative No.2 - was the Company's original preferred alternative, as presented at the November
<br />2001 Board Meeting, Upon further evaluation of the site, completion of the final design, and upon
<br />receiving actual construction bids in May of 2003, it was determined that this alternative was not in the
<br />best interest of the Company. The $0,81 per cubic yard bid submitted by the Contractor to dredge the
<br />reseIVoir, has made it feasible for the Company to look at creating the full 1,750 acre-feet storage right
<br />of the reseIVoir. The following is the estimated cost of Alternative No.2, as presented in November of
<br />2001, compared with the bid results received from the low bidder:

<br />.
<br />
<br />Proiect Item Original Cost Estimate R.E. Monk Bid
<br />Mobilization, Bonds, Insurance, $0 $169,525
<br />Seeding, Utilties, Water, etc.
<br />Embankment, Spillway, Toe Drain $390,000 $438,021
<br />Outlet Structure $100,000 $296,982
<br />Instrumentation $45,000 $32,000
<br />Dredging $375,000 $303,750
<br />Design Engineering $150,000 $294,000
<br />Inspection, Testing, Surveying, and $190,000 $206,077
<br />Contingency
<br />Total: $1,250,000 $1,740,355
<br />
<br />In comparing the original cost estimate of$I,250,000 for Alternative No.2, with the $1,740,355 cost
<br />provided by the Contractor, the total project cost to design and construct Alternative No.2 has increased
<br />by $490,355. This was mainly due to higher engineering costs, higher construction cost for the outlet,
<br />and not including a high enough contingency for mobilization, bonding, and construction water,
<br />
<br />Alternative No.3 was selected - since it allows the Company to achieve the full 1,750 acre-feet storage
<br />right. The decision to go with this alternative was largely due to the dredging bid price received from
<br />the Contractor, as previously mentioned. The following is a summary of the design and construction
<br />cost for Alternative No. 3, based on R.E, Monk's bid.
<br />
<br />Alternative No.3 Cost Estimate

<br />
<br />Proiect Item Estimated Cost
<br />Mobilization, Bonds, and Insurance $31,000
<br />Site Preparation $40,400
<br />Darn Embankment $380,739
<br />Outlet Works $296,982
<br />Spillway $89,282
<br />Dredging - 1,666,500 cubic yards $1,349,865
