Question 4 - Is the contractor responsible for providing signed & sealed drawings for the concrete headwalls & wingwalls?

Response to Question 4 - No, as long as the contractor uses the dimensions and reinforcement showing in the plans. Only if the contractor uses something different other than what is shown in the plans, then yes, the contractor shall provide signed and sealed drawings and calculations.

New drawings and calculations shall be signed and sealed by an engineered registered in Florida.

Question 5 - Are concrete link slabs required on top of the box culvert?

Response to Question 5 - If the precast concrete culvert opinion is selected, then yes, the concrete link slab is required per FDOT Index 400-291. Additional reinforcement shall be included in bid for precast concrete culvert opinion as indicated per the index.

Question 6 - Is the box culvert required to sit on a concrete slab or stone?

Response to Question 6 - According to FDOT Standards Specifications, Section 410, after the foundation is prepped, bedding stone should be used.

Question 7 - Per the FPL Dam Safety Plan, “The cuttings/spoils obtained from the excavation may not be used as backfill.” Will this statement still apply if the existing roadway embankment material is found to meet the requirements of select structural fill per fdot / AASHTO M 145 (soil classes A3, A1, A2-4)?

Response to Question 7 - Cuttings/spoils obtained from the excavation may not be used as backfill, even if the existing material tests within AASHTO structural fill ranges. Backfill must come from an approved, controlled source. This restriction is intentional because in situ embankment materials are inherently variable and can include organics, deleterious matter, and segregated fines that could compromise density, stiffness, and long-term performance.

Uncontrolled variability and organics increase the risks of settlement, loss of compaction, and internal erosion.

Question 8 – Per the FPL Dam Safety Plan, “No Excavations may be left open overnight until proper backfill requirements are met.” The large incidental excavation that will occur on the existing embankment required to get to the bottom of the wingwalls. What is the intent of the construction of the wingwalls (Excavation, Dewatering, Form and Pour, and Backfill)?

Response to Question 8 – The FPL Dam Safety Plan specifies excavation and backfill requirements for any excavations greater than 24” below grade. Upon review of the grading plan (sheet 11 of the contract plans set) and assessment of this specific question regarding the construction of the wingwalls, it appears the excavation required to get to the bottom of the wingwalls should not exceed 24” below the grade of the existing channel; therefore, the excavation requirements in this specific instance to construct the wingwalls may be left open overnight. Dewatering to one foot below the bottom of excavation will be necessary depending on the water table level in this area. Due to the proximity of the dam, FPL requests the Contractor to consider scheduling this portion of the construction in a way that minimizes time of open excavation work and form and pour as soon as possible following excavation. If the actual excavation required for the wingwall construction exceeds 24”, then work will stop immediately and the FPL Dam Safety Engineer will be notified to assess a new plan.

Question 9 – Do the Backfill and excavation requirements as listed in the FPL Dam Safety plan only apply to work occurring within the existing Channel?

Response to Question 9 – The entire project area is located within the dam exclusion zone;

therefore, the backfill and excavation requirements apply to any work associated with this project that requires excavation greater than 24” below grade.

Question 10 – Will be bedding stone be required underneath the Rip Rap Per FDOT

Specification 530-2.1.4?

Response to Question 10 – Sheet 03, Summary of Pay Items – Pay Item Note for 530-5-12A is revised to state “Includes the cost of materials, hauling, and dressing/shaping of subgrade for placement of riprap per Section 530 of the FDOT Standard Specifications. Additionally, this item includes the cost of Type D-2 geotextile fabric (17 SY) and bedding stone (10 TN) per Section 530 of the FDOT Standard Specifications.”

Question 11 – Please specify the height of the Concrete Shoulder Barrier?

Response to Question 11 – The Shoulder Concrete Barrier has a height of 38” per FDOT Standard Plans Index 520-001 sheets 13 and 14.

Question 12 – Are there any as-builts/ drawings of the existing bridge?

Response to Question 12 - Construction Plans for the existing bridge, FDOT Bridge No. 794162 are attached to this Addendum No. 2. Certified As-built Drawings for the existing bridge are not available.

Question 13 - Please consider extending the bid submittal date by two weeks.

Question 14 – What is the anticipated start date of construction?
