Memorandum
To: Board of Directors
From: Ed Taylor, Water Utility Manager
Date: 1-31-2003
Subject: Change Order Falcon Point#2
BACKGROUND:
The Board of Directors at the May 1, 2002 meeting awarded the Falcon Point Booster Station Project
contract to Longo Construction, Inc. The contract for the construction of the Falcon Point Booster
Station was $155,475.
The design for the Falcon Point Booster Station was based off of the as built drawings provided by Dart.
The as built drawings were for the construction of the Falcon Point Tank.The design was completed during
the winter months when snow prevented the site from being surveyed to determine the tank location.
The site was surveyed after the bid award but prior to the start of construction.The tank location was 3 feet
different than the as built drawings had indicated.The building and pump station design did not change,but
the elevation and the orientation were changed. The station had to be lower four feet into the embankment
which required additional excavation and additional concrete retaining wall construction.
On October 16, 2002 the Board approved Change Order#1 for this project. Staff is now requesting
that the Board approve Change Order#2, which completes this project.
ORIGINAL CONTRACT AMOUNT: $155,475.00
CHANGE ORDER#1 $14,475.39
CHANGE ORDER#2 $22,599.05
TOTAL AFTER CHANGE ORDER= $ 192,549.44
RECOMMENDATION:
I recommend that the Board approve Contract Change Order#2.

SUBJECT: FALCON POINT PUMP STATION-
PROPOSED CHANGE ORDER NO.2
Dear Ed,
I have reviewed the proposed change order and backup information submitted by project
contractor Longo, Inc. The Contractor prepared a comparison of the original bid amounts
and the actual costs for construction reflecting the changes in the pump station location.
The comparison includes credits to the District for work which was intended under the
original location but not completed,and extras for additional work required by the
relocation of the station. The amount of the changes is $37,299.03. The District has
already paid$14,700,00 in extras through Contract Change Order No- 1. Therefore the
amount due under the close out change order is $22,599.05-
Changes at the scope of work associated with the relocation of the pump station include:
I The 12" diameter suction and discharge pipeliue were eliminated from the
contract. This results in a credit of
1 t5 IT,X$85.00/i.f. =$9,775X-
2. The original location involved approximately 35 cubic yards of excavation. The
new location involved approximately 420 cubic yards of excavation,or a
difference of 395 cubic yards. This results in an increase of
385 c.v. X $80'00/0.v. =$30,900.00.
1 The new location required an additional 40 feet of 2" and 4" conduits. This
results in an increase of
40 l.f. X S69.60/l.f. =$2,784.00.
4. The gravel driveway was eliminated. This results in a credit of
600 c.y.X$2.20/c y =$1,320.00.

5. Pavement patching was eliminated. This results in a credit of
12 s.f. X S24.00/s,f. = $288.00.
6. Three concrete pump pedestals were eliminated from the contract. This results in
a credit of
3 ea. X $180 ca. = $540.00.
7. Portions of the building which were originally to be constructed as masonry block
were constructed as cast in place concrete retaining walls. This results in an
increase of
460 s.f. X $35.00/s.f. = $16,100-00.
8. Portions of the building which were originally to be constructed with wood
framing were constructed with masonry block. This results in an increase of
144 s.f. X$42.00/ s.f. _ $6,048.00 (gable end walls)
212 s.f. X$3.5,00/ s.f. = $7,420.00 (straight walls).
9. Masonry walls which were replaced by concrete retaining walls were eliminated.
This results in a credit of
672 s.f. X $35.00/s.f. = $23,520.00.
10. Wood framed walls which were replaced by masonry walls were eliminated.
This results in a credit of
144 s.f. X S21.63/s.f. =$3,114.72.
11. The roof structure which was originally to be wood frame rafters was constructed
with steel girders. This resulted in an increase of
616 s.f. X $39.58 = $24,381.28.
12. The wood rafter roof which was replaced by steel girders was eliminated. This
results in a credit of
616 s.f. X $24.92= $15,350,71
13. The steel rafter roof structure required additional flashings on eaves and gables.
This resulted in a lump sum increase of$1,043.39.

14. The steel roof structure resulted in the elimination of painting on eaves and
gables. This results in a hump stun credit of$760.00.
15. The Contractor added a 10% overhead and profit oa the additional work. This
results in a lump sum increase of$3,390.82,
The final breakdown of the project changes as a result of the relocation of the building is
ns follows:
Increase: $91,967.49
Credit: 554.668,14
Net Increase S37299.05
CCO No. 1 <$14 700.00>
Amount Due $22,599.05
I recommend the District approve a close out change order for the Falcon Point Booster
Pump Station for an increase of$22,599.05.
