103-1 Description.
103-1.1 Scope of Work: Construct temporary work structures used solely to support
construction equipment. Temporary structures include but are not limited to work bridges, elevated platforms, floating platforms, and rail systems. Items such as mats, falsework or scaffolding are not included in this Section. If a temporary structure type other than the structure type shown in the plans is chosen, assume responsibility for obtaining all necessary permit revisions and the Engineer’s approval. Conform to any limitations contained in the plans and permits. Do not place embankment outside the limits shown in the plans. The cost of the embankment, placing, compaction, and removal will be included in the lump sum price for Temporary Work Structure.
103-1.2 Materials: Construct the tempo rary work structure using materials sufficient to
handle the anticipated loads. Assume responsibility for the design of the temporary structure.
103-1.3 Navigation Requirements: Submit drawings showing the location of the
temporary work structures relativ e to the navigable waterway to the Coast Guard at least 60 days prior to beginning construction of the structure, or as required by conditions of the permit. Provide adequate lighting of the structure during the duration of construction as required by the Coast Guard or local authorities.
103-2 Basis of Payment.
103-2.1 General: The unit price for the temporary work structure will include all costs
associated with the design, materials, labor, installation, removal and disposal of the structure.
103-2.2 Partial Payments: When the plans include a separate pay item for temporary
work structure, 75% of the lump sum price will be paid upon completion of the temporary work structure, and 25% will be paid upon complete removal of the temporary work structure fro m the project site. When the project requires numerous structures or multiple setups (leap frog type) of the same system, the 75% will be split evenly between the various structures or setups. Partial payments for any project will be limited to 5% of the o riginal Contract amount for that project. Any remaining amount will be paid upon completion of all work on the project. When more than one project is included in the Contract, the above percentages will apply separately to each project which has a separa te pay item for temporary work structures. Payment will be made under: Item No. 103 - 1- Temporary Work Structures - lump sum.

104-1 Description.
Provide erosion control measures where work is accomplished in conjunction with the project, to prevent erosion, pollution of water, detrimental effects to public or private property adjacent to the project right -of-way and damage to work on the project.
104-2 General.
Coordinate the installation of temporary erosion control devices with the construction of the permanent erosion control devices to ensure economical, effective, and continuous control of erosion and water pollution throughout the life of th e Contract.
104-3 Control of Contractor’s Operations Which May Result in Water Pollution.
Prevent contaminants, pollutants or hazardous substances, as defined in Section 376.301, Florida Statutes, from migrating from the construction site or from material s and equipment into any surface waters, wetlands, groundwater or property beyond the project limits. Conduct and schedule operations to avoid and minimize pollution or siltation from the project to surface waters, wetlands, groundwater, or property beyond the project limits. Do not drive in, operate, or place construction equipment or materials in surface waters, wetlands, groundwater, or property beyond the project limits without permitted authority for permanent or temporary impacts. Water crossings or other wetlands impacts must be authorized by permit. Obstructing or impeding the water flow or movement of the water or wildlife must be authorized by permit. Where pumps are used to remove highly turbid waters from enclosed construction areas such as cof ferdams or forms, treat the water by one or more of the following methods prior to discharge from the project: pumping into grassed swales or appropriate upland vegetated areas or constructed sediment basins, or confined by an appropriate enclosure such as turbidity barriers when other methods are not practical. Do not discharge, water that does not meet State water quality standards or does not meet the criteria specified in any applicable permit. Remove sediment accumulated during construction from all e xisting or newly constructed stormwater facilities prior to final acceptance. Ensure that all stormwater conveyances and stormwater facilities meet final grade requirements at final acceptance. Remove silt or regrade as necessary to comply with the lines a nd grades shown in the Plans. Do not enter onto lands or waters outside the limits of construction as staked, except as authorized by the Engineer. Do not allow water that does not meet state water quality standards or does not meet the permitted criteria to exit the project limits. Obtain the Engineer’s approval for the location and method of operation in borrow pits, material pits, and disposal areas furnished for waste material from the project (other than commercially operated sources) such that erosi on during and after completion of the work will not result in detrimental siltation or water pollution.
104-4 Materials for Temporary Erosion Control.
For materials that are part of the permanent work, meet the testing requirements of the applicable perma nent materials. FY 2023-24 Return to Table of Contents
