Subject: Change Order 008
Ms. London
Change Order 08 is due to plan revision 7 which calls for a new Ditch Bottom Inlet, installing 15-inch pipe,
sidewalk, detectable waring, type F curb and gutter, subbase, asphalt base, structural asphalt, coring of a structure,
additional MOT, additional mobilization,clearing, and grubbing.There is also a deduction of the following contract
work: pipe lining, sealing manholes and structures, and desilting pipe. The breakdown of credits and debits are
below in the order of pay items as shown on the backup document.
This change order also includes a new partial manhole to replace the existing manhole in the intersection of North
Roosevelt and First Street. The existing manhole ring and cover had failed, the lid was lower than the ring and it
was welded shut. The contract required the contractor to have access to install pipe liner and as part of the work,
the deficient manhole was replaced.
The contractor will have to remobilize and demobilize equipment and crews to perform the additional work from
Plan Revision 7.Based on the negotiated price for pay item 101-1,the additional mobilization increased the contract
by $13,860.00.
Additional MOT is required to perform the work for plan revision 7 and based on the negotiated price for pay item
102-1, the additional MOT increased the contract by $17,500.30.
Plan revision 7 requires additional clearing and grubbing which includes the contractor to remove sidewalk, curb,
and gutter, one structure, and excavate through 12 inches of asphalt. Based on the negotiated price for pay item
102-1 Clearing and Grubbing, the additional clearing and grubbing increased the contract by $6,000.00.
Plan revision 7 requires placing 90 SY of asphalt base under pay item 285-715 OBG 15 (asphalt base) at the
contract unit price of$63.50 per SY. The total estimated increase to the contract for this pay item is $5,715.
Plan revision 7 requires placing 12 tons of structural asphalt under pay item 334-1-53 Superpave Asphalt Traffic
C PG 76-22 at the contract unit price of$155.00 per ton. The total estimated increase to the contract for this pay
item is $1,860.00.
Plan revision 07 added a new pay item 425-1-523 Inlets Ditch Bottom Type C JBOT <10' F&I to replace the
existing structure S-61. The negotiated price for the new pay item increased the contract by $17,104.42.
The existing ring and cover of a manhole located at the intersection of First Street&North Roosevelt had existing
damage and was welded shut. To install the liner and repair the deficient structure, the contractor was directed to
replace the manhole as part of gaining access. This resulted in an increase to pay item 425-2-43 Manhole Partial P-
7, $3,555.00 per each. The total increase to the contract for this pay item is $3,555.00.
Plan revision 07 added a new pay item 430-175-115 Pipe Culvert Optional round 15" S/SD for 51 LF of pipe. The
negotiated price for the new pay item is $371.76 per LF. The total increase to the contract for this pay item is
$18,959.76.
The plans called for the existing pipe from S-58 to S-61, S-61 to S-61A and S-61A to S-62 to be desilted. The plan
revision 7 calls for the pipe to be replaced which eliminated the requirement to desilt the pipes. This resulted in a
deduction of 59 LF for pay item 430-94-1 Desilting Pipe 0-24" at the contract unit price of$3.00 per LF. The total
decrease to the contract for this pay item is $177.00.
The plans called for the existing pipes to be lined from S-58 to S-61, S-61 to S-61A and S-61A to S-62.Now that
we are replacing the pipes the lining is not required. This results in a deduction of 59 LF for pay item 431-1223
Cured in Place Pipe Liner 15" at the contract unit price of$159.00 per LF. The total decrease to the contract for this
pay item is $9,381.00.
Plan revision 7 requires replacing an estimated quantity of 42 LF of curb and gutter. The contract unit price for pay
item 520-1-10 Type F Curb and Gutter is $20.25 per LF. The total increase to the contract for this pay item is
$850.00.
Plan revision 7 requires replacing an estimated quantity of 40 SY of sidewalk. The contract unit price for pay item
522-1 Concrete Sidewalk is $87.50 per SY. The total increase to the contract for this pay item is $850.00.
Plan revision 7 requires replacing an estimated quantity of 8 SF of detectable warning. The contract unit price for
pay item 527-2 Detectable Warning is $26.00 per SF. The total increase to the contract for this pay item is $208.00.
Plan revision 7 requires core drilling of S-58 to install 15-inch pipe to connect to S-61. The negotiated price for this
work is $2,844.60. The total increase to the contract for the additional work is $2,844.60.
Initially the contractor submitted a change order totaling $106,484.17. After negotiation with the CEI the final
negotiated change order amount for Change Order 008 is $83,049.58. The contractor requested 70 additional days
due to time for design of plan revision 7, time for submittals and submittal review, procurement and casting of a
precast structure,procurement of pipe materials, and remobilization. Given the amount of additional work we find
this to be acceptable.
Sincerely,
