TITLE: Approval of Amendment No. 1 to Contract No. 2013-52 with Ajax Paving Industries of Florida, LLC in the amount of $407,339.99 and approve additional funds of $41,600 for contingencies.
Recommended Action
Motion to approve Amendment No. 1 to Contract No. 2013-52 with Ajax Paving Industries of Florida, LLC. In the amount of $407,339.99 and approval of additional funds of $41,600.00 for contingencies.
Background Information
The widening of Sumter Boulevard, between Heron Creek Boulevard and City Center Boulevard, includes construction of a four-lane divided roadway with a raised center median, decorative roadway and pedestrian lighting, multi-use pathways, trail signage, irrigation and landscaping. Also included is the reconstruction of Price Boulevard to a four-lane divided roadway section with raised center median and decorative roadway lighting extending about one quarter mile in each direction from Sumter Boulevard.
Price Boulevard was designed and constructed with an open swale drainage system conveying stormwater into the outfall of the Myakkahatchee Creek. Due to the high water table in this area, the existing swales on this segment of Price Boulevard to the Myakkahatchee Creek are typically saturated with water. The continuous wet conditions of the swales have contributed to the following negative impacts:
1. The maintenance of the swales has been problematic.
2. The capacity of the swales diminishes over time from damage due to the shape and flow line of the swales when trying to mow them.
3. Occasionally, vehicles leave the paved roadway leaving deep ruts in the swales, further reducing their flow capacity.
4. During heavy rainstorms, the water pools on the sidewalks for extended periods of time resulting in algae growth. The algae growth is potentially a safety hazard for pedestrians and bicyclists. In addition, removal of the algae from the sidewalks is very labor intensive throughout the rainy season.
In order to address these negative impacts, the Sumter Boulevard Phase IIIA Widening Project Engineer-of-Record, Kimley-Horn and Associates, was tasked to design a system to dry-out the swales so their storm drainage flow capacity can be reasonably maintained. The system selected for implementation is a perforated pipe buried several feet in the swales and encased in a rock trench. The perforated pipe will be connected to the two terminal stormwater inlet structures mentioned above, so they can partially empty after a rain event. The roadside swales will be reshaped and graded for maximum flow capacity to the Myakkahatchee Creek. The increased impervious surface of the new four lane segment of Price Boulevard from Sumter Boulevard to the west increases the stormwater flow through these swales to the Myakkahatchee Creek. Restoring and preserving flow capacity of the Price Boulevard roadside swales will significantly reduce the risk of roadway flooding of this arterial road.
The Sumter Boulevard Phase IIIA widening project is being funded through a $10 million loan from the Florida State Infrastructure Bank Program, approved by the City Commission during their meeting on May 14, 2012. The bid for this project was $9.5 million dollars. The stormwater improvements on both sides of Price Boulevard from Sumter Boulevard to the Myakkahatchee Creek were not included in the original design of the Sumter Boulevard Phase III-A widening project due to funding constraints. However, since there have been cost savings realized in this project, such as reduced asphalt quantities, resources, maintenance of traffic, etc., staff believes it to be appropriate to proceed with the Price Boulevard stormwater improvements.
It would be most cost efficient and expedient to amend the contract for Ajax Paving Industries of Florida to include the Price Boulevard stormwater improvements since they are on-site constructing the Sumter Phase IIIA Widening Project and familiar with the site conditions. The construction plans for this swale drainage system were provided to Ajax Paving Industries for pricing, with the contract cost and time reflected in this contract modification.
The current contract with Ajax Paving Industries of Florida, LLC is $9,263,006.04, with a remaining contingency amount of $115,286.80. Contract Amendment No. 1 adds $407,339.99 for this work. Additional funds in the amount of $41,600.00 are being requested for contingencies for the completion of the project. Bringing the total amended contract amount to $9,670,346.03 with a revised contingency balance of $156,886.80.
