PART 3 EXECUTION

3.1 VIBRATION CONTROL PROGRAM

Implement a program that protects existing structures from damages that result from construction equipment operations and vibrations. The purpose of the program is to avoid damages and potential claims that allege damages were caused by construction activities. The Contractor is responsible to document pre-existing conditions, to avoid damaging existing structures that were determined to be susceptible to vibration damage, and to avoid damaging existing structures that were not determined to be susceptible to vibration damage; related responsibilities include inspection, damage claims, and work stoppage that results from monitoring.

The Contractor's attention is called to Clauses PERMITS AND RESPONSIBILITIES and PROTECTION OF EXISTING VEGETATION, STRUCTURES, EQUIPMENT, UTILITIES AND IMPROVEMENTS of Section 00700 CONTRACT CLAUSES in Volume 1 of this contract that define the Contractor's responsibilities.

The Contractor shall process any claim arising from his operation; in particular, all property damage claims shall be acknowledged by the Contractor (or his agent) immediately, and the claimed damage inspected within 30 calendar days following initial notification, and processed to a conclusion (honored, denied, or compromised) within 90 calendar days after completion of the contract; but, in no case shall the claim(s) remain unresolved for a period exceeding six months.

3.2 PRE-CONSTRUCTION STRUCTURAL SURVEY

Inspect existing structures within 200 feet from the beach fill limit as to their potential susceptibility to vibration damage from construction equipment induced ground vibration. Visible structural and/or cosmetic damage to buildings, exterior walls, foundations, decks, walkovers, staircases, revetments , pools, bulkheads and seawalls shall be documented

SECTION 02 22 13 Page 4 by photographs, sketches, and field notes.

Factors to consider in determining potential susceptibility shall include but not be limited to: foundation design; foundation conditions; soils testing data; changes in structural loads and local water levels due to beach fill placement; structural condition including construction materials; past damage history and existing stresses, magnitude, frequency, and duration of predicted vibrations from construction equipment and distance from fill placement.

Inspect all existing structures that are determined to be vibration sensitive. Any damage found shall be documented thoroughly by photographs (supplemented with video as necessary), sketches of visible structural and/or cosmetic damage, and field notes. Photographs shall be at least 3-by 5-inch (or digital) and shall provide a detailed visual explanation of the damage. Include a reference scale in each close-up photograph.

Sketches shall show the general damage location and extent. All inspection items shall be indexed and cross-referenced and shall use the stationing and locations shown on the contract drawings. Include hotel/motel names and addresses where applicable. Structural damage shall be additionally documented by measuring crack or damage size, width, and length. Every effort shall be made to inspect and document the condition of the building's interior where the building has been determined to be extremely susceptible to vibration damage. Structure(s) determined not to be susceptible to vibration damage shall be noted as such.

3.3 VIBRATION CONTROL PLAN

Use the results of the Pre-Construction Structural Survey to develop the Vibration Control Plan. The Plan shall include procedures to monitor vibration sensitive structures, adjust daily mobilization and demobilization activities, and alter fill placement operations. The Plan shall include the appropriate tolerable ground vibration level for each structure that has been determined to be susceptible to vibration damage.

Should ground vibrations equal or exceed the pre-determined maximum vibration level(s), construction operations shall be halted and corrective measures taken in accordance with the approved Plan.

The minimum safe working distance that vibration producing equipment may operate from each vibration sensitive structure shall be documented in the Plan.

The maximum allowable ground vibration level that is permissible without causing threshold damage to each vibration sensitive structure shall be documented in the Plan. Threshold damage is defined as the occurrence of cosmetic damage.

Each seismograph shall have the capability to measure peak particle velocity and frequency and shall be equipped with an alarm system to alert the Vibration Control Specialist that ground vibrations are approaching the maximum tolerable ground vibration level. Seismographs shall record measurements 24 hours a day, 7 days a week. Seismographs shall be installed and shall be properly working prior any construction activities, including mobilization and demobilization of all construction equipment, and fill placement operations.

The Contractor's personnel responsible for implementation of the Plan is hereinafter called Vibration Control Specialist. The Vibration Control Specialist shall be on site at the active fill location during all fill

SECTION 02 22 13 Page 5 placement operations that can affected vulnerable structures. However, seismographs used for the 24/7 monitoring shall be capable of 24-hour real time notifications capable of being sent directly to the Vibration Control Specialist and Vibration Control Technicians. Ground vibrations shall be kept in allowable levels to avoid damaging existing structures that were determined to be susceptible to vibration damage, and to avoid damaging existing structures that were not determined to be susceptible to vibration damage. Additionally, the Vibration Control Specialist will provide support to the Contractor to best mitigate against direct impacts to structures or indirect impacts to structures due to uncontrolled loading.

3.4 DAILY INSTRUMENT LOG

The Contractor's personnel responsible for implementation of the Plan is hereinafter called Vibration Control Specialist. The Vibration Control Specialist shall be on the site during mobilization and demobilization of all construction equipment; and during the fill placement operations that can affect the vibration sensitive structures (as defined in paragraph PRE-CONSTRUCTION STRUCTURAL SURVEY above). When the construction activities do not involve any vibration sensitive structure, the Vibration Control Specialist may choose not to be on site. However, seismographs used for the 24/7 monitoring shall be capable of 24-hour real time notifications capable of being sent directly to the Vibration Control Specialist and Vibration Control Technicians. Ground vibrations shall be kept in allowable levels to avoid damaging existing structures that were determined to be susceptible to vibration damage, and to avoid damaging existing structures that were not determined to be susceptible to vibration damage.

3.5 VIBRATION MONITORING REPORT

The monitoring report shall detail the daily activities of the vibration monitoring program. This report shall include, but not be limited to, locations of monitoring equipment; instrument serial number; date and times of readings; magnitude of vibration levels; a sketch and photograph (3- by 5-inch) of each monitoring station showing the relationship of the monitor to vibration sensitive structures; daily instrument logs;

instructions transmitted to the Contractor's personnel regarding the modification or stoppage of work operations to keep vibrations below the allowable levels; description of complaint(s); and, any other information pertinent to the vibration monitoring program.

3.6 POST-CONSTRUCTION STRUCTURAL SURVEY

Immediately after completion of work, conduct a post-construction inspection of the structures previously inspected under the Pre-Construction Structural Survey. Documentation procedures shall be identical to those performed under the Pre-Construction Structural Survey. Changes or deviations from the pre-construction inspection conditions in any structure shall be identified and described in the inspection documentation. All citizen complaints and remedies that occurred during the placement of beach fill shall be summarized and included in the report.

SECTION 35 20 25 Page 3

Contractor cannot remove material below this depth. Contractor will not be penalized for locations in the borrow area which were already deeper than maximum depth prior to dredging. The Florida Department of Environmental Protection (FDEP) designated "disturbance depth" is a 2 foot layer located beneath maximum depth in which material can be agitated but not removed.

1.3.5 Target Depth

The borrow area and each subdivision shall be completely exacavated to the target depth before relocating the dredge to another borrow area or subdivision. The Contracting Officer may permit the Contractor to relocate to another borrow area or subdivision prior to complete clearance to target depth if 1) the remaning quantity is the result of minor side slope sloughing, 2) in isolated areas the remaining sand thickness cannot be efficiently removed after suitable effort by the contractor to clear the entire borrow area or subdivision to target depth, or 3) other reasons determined valid by the Contracting Officer.

1.3.6 Work Area
