BACKGROUND INFORMATION:
The Waterline Improvement Contract was awarded to Atkins Brothers Construction
Company Inc. by City Council on January 19, 1999. This project consists of new 16" and
12" waterlines along Dove and Kimball Roads. Also included in the project is the
installation of a 24" water line along William D. Tate Avenue and the rehabilitation of a
sanitary sewer line beneath Pebblebrook Drive.
Change Order No 1 was approved by City Council on January 19, 1999. This change
order reduced the original contract amount after the contractor re -reviewed material costs
with suppliers and found an error in their bid for the pavement repair and backfill bid item.
Change Order No 2 was approved by City Council on August 4, 1999. This change order
addressed items along Kimball Road and William D. Tate Avenue.
Change Order No 3 was approved by City Council on September 21, 1999. This change
order addressed the addition of a sanitary sewer manhole in Pebblebrook Drive,
additional 16" water main in the vicinity of the Dove Road and Sagebrush Drive
intersection, and extension of a 12" water main in the Kimball Road Curve vicinity.
Change Order No. 4 serves as the cleanup change order which involves adjustments to
each contract pay item to match the actual quantities in the field. Items of significant
interest are as follows:
12" PVC Waterline Item increased by 56 LF on Dove Road and by 102.5 LF on Kimball
Road. These increases reflect 1.) a portion of the 12" line having to be removed and re-
laid due to a sanitary sewer line conflict discovered after the line was in the ground, and
2.) 12" stubouts were added to the entrance of Meadowmere Park at Kimball Road and to
the Kimball Road segment south of the Dove Road intersection for future extensions.
Cost $ 3,304.00 Increase Dove Road; $ 6,970.00 Increase Kimball Road
Replace Concrete Sidewalk Item increased by 270.5 SF on Dove Road. Approximately
65 LF of added sidewalk repair was needed to mitigate fire hydrant relocations and to
replace the sidewalk in the vicinity of the Sagebrush Drive and Dove Road intersection
where the 16" waterline connection took place. Cost $ 1,893.50 Increase
Replace Concrete Sidewalk Item increased by 572 SF on Kimball Road. The planned
16" Waterline location had to be adjusted to clear an existing sanitary sewer line at the
south end of Kimball Road near Dove Road. The only area available for the waterline
required approximately 143 feet of sidewalk to be removed and replaced. Cost $ 4,004.00
Increase
Replace Hot Mix Asphalt Item increased by 67.75 SY on Kimball Road. The
construction of the 16" waterline close to the pavement edge would have resulted in an
uneven asphalt edge upon completion of the trench repair. Staff directed contractor to
widen the pavement repair to provide a consistent pavement edge. Cost $ 3,184.25
Increase
Bore or Tunnel 42" Sleeve Item increased by 31 LF on William D. Tate Ave. The revised
plan quantity of 865 feet to bore and insert a 42" sleeve beneath the SH 114 Frontage
Roads and the Main Lanes was slightly short of the actual in field measurements by 31
feet. Cost $ 12,803.00 Increase
Rock Excavation or Tunneling Item increased by 220 LF on William D. Tate Ave. The
contractor encountered 220 LF of extremely hard rock during the excavation for the 24"
waterline between SH 114 Frontage Road and Mustang Drive. Normal crew progress
was reduced from 100 feet per day to 16 feet per day. Cost $ 21,340.00 Increase
Investigation Costs Item is a new item reflecting costs that were incurred by contractor
during the time when the contractor and staff could not confirm the location, size and
alignment of the existing waterlines in the Dove Road intersection with Sagebrush Drive.
The City's construction plans for the 1974 Dove Tank construction project, including the
16" waterline connection from the tank to the City's water network, were not reflective of
the actual field conditions, including line sizes, line locations and valve locations. Change
Order# 3 addressed the actual quantities needed to make the connection of the 16" line
under construction with the existing facilities and the replacement of undersized lines.
The change order did not include the added cost incurred by the contractor in terms of
lost productivity.
The contractor experienced two days of crew down time and an added two and one half
days of crew time with City staff to finally locate the existing lines due to the problems with
the Dove Tank plans. Cost $ 11,503.00 Increase
HIVIAC Overlay Outside of Trench and Pavement Milling Items are two new items
reflecting instructions from Staff to the contractor to improve the riding surface in areas of
Kimball Road and Dove Road. The trench repairs and associated pavements repairs
were constructed under a different pay item at a much higher cost, $ 47.00 per SY, due to
the depth of the pavement placement. These two items involved the milling of the
pavement surface to provide a sound pavement joint and the 2" overlay of a much wider
area using an asphalt machine to provide a smooth travel surface. This cost reflects only
the 2" overlay beyond the trench repair area at a $ 9.25 per SY cost. The contractor
absorbed the proportionate cost of this overlay covering the trench repair area. Cost
$ 4,434.91 Increase Overlay; $ 1,766.12 Increase Milling
The net increase of $ 47,057.10 reflects the quantity increases noted above, some
additional minor increases, and offsetting quantity decreases.
The change orders to the project total $ 214,659.60 which represents 10.9% of the
original contract. This includes the costs experienced due to 1.) Old City plans being
considerably different from the actual field conditions and 2.) modifications to the project
scope on the north end of Kimball Road to extend the 12" waterline beyond the future fill
area east of the Meadowmere Park entrance.
Excluding these costs, the total change orders would be reduced to $ 92,599.10 which
represents 4.9 % of the original contract.
Staffs goal is to keep change orders on construction contracts below 5%. Retrofit
projects in developed areas and roadway corridors typically experience more change
orders due to the uncertainty of existing facility locations and the necessity to coordinate
with and connect to or maintain minimum clearances from those facilities.
Staff recommends approval.
