DIVISION 1: GENERAL REQUIREMENTS SECTION 01010 SUMMARY OF WORK

GENERAL

SUMMARY: The work includes the construction of a cantilever sheet pile wall with an overflow weir; excavation of subsurface highly organic material and disposal; backfilling and compaction; construction of earthen embankments; stabilization of embankment side slopes; installation of concrete drainage pipe; construction of fabriform and rip rap overflow weir structures, and installation of shrubs, grasses and aquatic vegetation.

PROJECT DESCRIPTION: This project consists of the construction of a stormwater treatment filter marsh system (Riverside Filter Marsh) for the City of Naples Goodlette Road Pump Station. Presently, stormwater from the Goodlette Road Pump Station enters untreated into the Gordon River. The Riverside Filter Marsh will intercept stormwater runoff from the Goodlette Road Pump Station for treatment prior to its discharge into the Gordon River. The Gordon River is listed as an impaired water body for nutrients, dissolved oxygen, biochemical oxygen demand, and coliform by the Florida Department of Environmental Protection (FDEP).

The stormwater treatment filter marsh system is a 1.4-acre system that incorporates a sediment sump and two treatment marshes. The system will be installed in an upland area between a mangrove wetland and the A parking lot. The stormwater will be routed into the proposed system by a sheet pile wall installed across the existing pump discharge channel. This upstream portion of the channel becomes the sediment sump, where trash and heavy sediments are collected. Runoff is then directed through two linked filter marshes which will provide additional retention time and uptake of nutrients. After the stormwater has passed through the treatment train it will be discharged into the existing mangrove wetland for final polishing and then allowed to flow into the Gordon River. When water levels rise in the filter marshes, fabriform weirs will allow water to overflow into the mangrove wetland where the treated water will move as sheet flow out to the Gordon River. During extreme high flow events, water will overtop the weir in the sheet pile wall and bypass the system, directly flowing into the Gordon River, preventing potential flooding of adjacent and upstream properties. The treatment marshes are designed as wet ponds containing wetland plant species with high nutrient uptake potentials. Upland vegetation will be planted around the filter marshes, and over the connecting pipe. The filter marshes are designed for stormwater treatment and an enhancement to the wildlife habitat surrounding the mangrove.

CONTRACT ACTIVITIES:

The CONTRACTOR shall install weirs, construct an embankment, and provide bank stabilization and protection of the work area to control access to the job site.

A. Pile Driving Equipment: Provide pile-driving equipment conforming to the following requirements.

Driving Hammers: Hammers shall be steam, air, or diesel drop, single-acting, double-acting, differential-acting, or vibratory type. The driving energy of the hammers shall be between 8,750 and 16,000 foot pounds as recommended by the manufacturer for the piling weights and subsurface materials to be encountered. Repair damage to piling caused by use of a pile hammer with excess delivered force or energy.

Placing and Driving

Placing

Any excavation required within the area where sheet pilings are to be installed shall be completed prior to placing sheet pilings. Pilings properly placed and driven shall be interlocked throughout their length with adjacent pilings to form a continuous diaphragm throughout the length or run of piling wall.

Pilings shall be carefully located as shown or directed. Pilings shall be placed plumb with out-of-plumbness not exceeding 1/8 inch per foot of length and true to line. Place the pile so the face will not be more than 6 inches from vertical alignment at any point. Top of pile at elevation of cut-off shall be within 1/2 inch horizontally and 1/2 inch vertically of the location

indicated. Manipulation of piles to force them into position will not be permitted. Check all piles for heave. Re-drive all heaved piles to the required tip elevation.

Driving

Prior to driving pilings in water, a horizontal line shall be painted on both sides of each piling at a fixed distance from the bottom so that it shall be visible above the water line after installation. This line shall indicate the profile of the bottom elevation of installed pilings and potential problem areas can be identified by abrupt changes in its elevation. Pilings shall be driven with the proper size hammer and by approved methods so as not to subject the pilings to damage and to ensure proper interlocking throughout their lengths.

Driving hammers shall be maintained in proper alignment during driving operations by use of leads or guides attached to the hammer. Caution shall be taken in the sustained use of vibratory hammers when a hard driving condition is encountered to avoid interlock-melt or damages. The use of vibratory hammers should be discontinued and impact hammers employed when the penetration rate due to vibratory loading is 300 mm one foot or less per minute.

A protecting cap shall be employed in driving when using impact hammers to prevent damage to the tops of pilings. Pilings damaged during driving or driven out of interlock shall be removed and replaced at the CONTRACTOR's expense.

Pilings shall be driven without the aid of a water jet.

Adequate precautions shall be taken to ensure that pilings are driven plumb. Where possible, drive Z-pile with the ball end leading. If an open socket is leading, a bolt or similar object placed in the bottom of the interlock will minimize packing material into it and ease driving for the next sheet. If at any time the forward or leading edge of the piling wall is found to be out-of-plumb in the plane of the wall, the piling being driven shall be driven to the required depth and tapered pilings shall be provided and driven to interlock with the out-of-plumb leading edge; or other approved corrective

measures shall be taken to ensure the plumbness of succeeding pilings. The maximum permissible taper for any tapered piling shall be 1/8 inch per foot of length.

Pilings in each run or continuous length of piling wall shall be driven alternately in increments of depth to the required depth or elevation. No piling shall be driven to a lower elevation than those behind it in the same run except when the pilings behind it cannot be driven deeper. Incrementally sequence driving of individual piles such that the tip of any sheet pile shall not be more than 4 feet below that of any adjacent sheet pile. When the penetration resistance exceeds five blows per inch, the tip of any sheet pile shall not be more than 2 feet below any adjacent sheet pile. If the piling next to the one being driven tends to follow below final elevation it may be pinned to the next adjacent piling.

If obstructions restrict driving a piling to the specified penetration, the obstructions shall be removed or penetrated with a chisel beam. If the CONTRACTOR demonstrates that removal or penetration is impractical, the CONTRACTOR shall make changes in the design alignment of the piling structure as directed to insure the adequacy and stability of the structure.

Where dissimilar metals are in contact, protect surfaces with a coat conforming to MPI 79 to prevent galvanic or corrosive action. Where aluminum is in contact with concrete, plaster,

mortar, masonry, wood, or absorptive materials subject to wetting, protect with ASTM D 1187, asphalt-base emulsion.

B. Field Preparation

Remove rust preventive coating just prior to field erection, using a remover approved by the rust preventive manufacturer. Surfaces, when assembled, shall be free of rust, grease, dirt and other foreign matter.

C. Environmental Conditions

Do not clean or paint surface when damp or exposed to foggy or rainy weather, when metallic surface temperature is less than -15 degrees C 5 degrees F above the dew point of the surrounding air, or when surface temperature is below 7 degrees C or over 35 degrees C 45 degrees F or over 95 degrees F, unless approved by the Contracting Officer.
