Site work for a water / sewer project in Safety Harbor, Florida. Conceptual plans call for site work for a water / sewer project.

25-0601-ITB-C Philippe Park Wastewater Collection System Improvements (PID 000341G) The construction of shell aggregate must conform to the requirements of Section 204 and 285 of the FDOT Specifications, as amended herein. The work specified under this Section consists of the construction of shell on prepared subgrade, in conformity with the lines, grades, notes and typical cross sections shown in the Plans, and as directed by the Engineer. The construction of Shell must conform to the requirements of this Section, or, in lieu thereof, such requirements as may be established by the Engineer during construction. The Engineer must have full authority to modify the provisions of this Section as deemed necessary, in his opinion, to meet field conditions and requirements. Material for Shell must consist only of Shell and such additive materials as may be approved by the Engineer for the purpose of facilitating construction and achieving the desired characteristics of the finished in-place product. The use of water for this purpose is considered incidental to work performed and will not be paid for separately, regardless if the contract includes a Water for Dust Control pay item. Material which shows a significant tendency toward adverse chemical or physical change on exposure to moisture will not be acceptable. The material must be free of any Ferrous Metals. The specific mechanical and physical properties of Shell and any additive materials permitted in the construction of Shell under this contract must be determined on the basis of test results as the work progresses. The finished in-place product must provide at least an LBR of 100 or greater. Placement and Spreading of Material The material must be transported to the point where it is to be used, over Shell previously placed where possible, and dumped at the end of the preceding spread. Hauling over the subgrade, or dumping on the subgrade for further placement operations, will be permitted only when, in the opinion of the Engineer, such procedures will not adversely affect the integrity of the completed base and subgrade. Spreading must be accomplished by mechanical spreaders capable of producing an even distribution of the Shell. Spreading by other means must be permitted only where and as directed by the Engineer. The minimum thickness of the Shell constructed under this contract must be as specified for the project. Compacting and Finishing Requirements After spreading is completed the shell must be uniformly compacted, with water being added as required, to a density of not less than ninety eight (98%) of the maximum density as determined by AASHTO T- 180. During final compaction operations, if the blading of any areas is necessary to obtain the true grade and cross section, the compacting operations must be completed prior to the performance of density tests on the finished base. Water associated with the use of this material is considered incidental to work performed and will not be paid for separately, regardless if the contract includes a Water for Dust Control pay item. Correction of Defects All defects in materials and construction must be corrected by the Contractor, at the Contractor's expense, and to the satisfaction of the Engineer, as the work progresses.

Scope of Work 7.1. OBJECTIVE/JUSTIFICATION Work in this project includes the installation of a new wastewater collection system consisting of approximately 2,800 linear feet of force main and four wastewater pumping stations in Philippe Park that will replace four onsite septic collection systems. The new system will connect to the City of Safety Harbor's wastewater collection system through the existing Lift Station No. 614. In addition, approximately 50 linear feet of the Lift Station No. 614 force main will be replaced at both the Lift Station and the discharge manhole. Additionally, this project is partially funded with grant funds from the Florida Department of Environmental Protection. Please see Appendix 4 Special Notices for grant requirements under this contract. 7.2. BACKGROUND The County requested a project to review the existing aging sanitary sewer infrastructure within Philippe Park. The current septic system is at risk of failure which requires significant additional regular maintenance. As stewards of public resources, rehabilitation and transformation of the existing sanitary system aims to eliminate ongoing risk of wastewater contamination into the groundwater system as well as the environmentally sensitive portion of upper Old Tampa Bay. Efforts undertaken in this project will align with the County's desire to identify and address existing infrastructure as potential opportunities for environmental and fiscal stewardship by increasing infrastructure resiliency and protect or improve environmentally sensitive areas.
