Summary:
This change order is required to address several conditions that contributed to unexpected costs during construction. There were several discrepancies between the plan quantities and the actual quantities installed in the field. Conditions included:
1. Concrete Class IV, Culverts; Reinforcing Steel, Misc.; Sodding, Bahia; Sodding, St. Augustine for a total of $181,424.07, or approximately 73% of the change order amount.
2. Unforeseen utilities not shown on the plans were encountered in the field requiring field modifications to new structures and adjustments of quantities. An example includes adding a large conflict structure to the box culvert storm sewer for a gravity sewer line.
3. Modifications to a storm sewer structure were required to accommodate a future storm sewer connection from the north that was not addressed in the plans.
4. Additional costs associated with the restoration of an easement at 5399 97th Way North.
The remaining items address additional cost for work changes to County Utilities. The consultant, Burges and Niple, will not be held responsible to pay for the underestimated quantities and missed pay items as they are needed to complete the project. These additional items, in retrospect, should have been advertised in the original bid and thus, included in the contractor’s bid submittal.
Background/Explanation:
The Board awarded this contract on November 12, 2019 in the amount of $2,985,248.93. These improvements reduced the one hundred (100) year floodplain elevation for structures and the existing flooding problems for streets during the ten (10) year, twenty-four (24) hour storm event. The improvements also increased the overall two hundred fifty-five (255) acre system conveyance to Long Bayou providing subsequent additional drainage improvements in the watershed. Water quality benefits will now be achieved through additional stormwater treatment of currently untreated areas.
Fiscal Impact:
Original expenditure not to exceed: $2,985,248.93
Increase due to Change Order No. 1: $ 249,952.18
Revised total expenditure: $3,235,201.11
Funding is derived from the Local Infrastructure Sales Tax (Penny for Pinellas) and Cooperative Funding from The Southwest Florida Water Management District. The project is budgeted in the Capital Improvements Program: Physical Environment.
