3.7 QUALITY CONTROL FOR BEACH FILL

The Contractor shall continuously ensure beach fill material is in compliance with the contract requirements. The Contractor shall produce daily reports which characterize the nature of the beach fill along the project shoreline with specific reference to the "Compliance Criteria for Beach Fill Material" paragraph below. At the Preconstruction Conference, the Contractor shall acknowledge the quality of beach fill as described in subparagraph "Compliance Criteria for Beach Fill Material". The Contractor shall develop a "Noncompliant Material Contingency Plan" and if so directed by the Contracting Officer, acquire the equipment and personnel to remediate the beach fill area. If required, determination of areal extent of non-compliant beach fill area and/or area needed for remediation shall be at the Contractor's expense.

3.7.1 Compliance Criteria for Beach Fill Material

Beach fill material shall conform to the compliance values presented in Table 1 (all sieve sizes refer to U.S. Std. sieves) below. The sand shall be similar to the existing beach sediments in color and texture. Based on the Munsell Soil Color Chart, color must be within the range of Hue 2.5 YR, 5 YR, 7.5 YR, 10 YR, 2.5 YR or 5Y and Chroma 1, 2 or 3. Beach fill material shall be clean sand from the permitted source and free of unacceptable materials, such as construction debris, asphalt, rocks greater than 3/4 inch, clay balls, and other organics, oil, pollutants and any other foreign materials.

SECTION 35 30 00 Page 15

Table 1 - Fill Material Compliance Values

Maximum Silt Content (passing #230 sieve) 2 percent Maximum Fine Gravel Content (retained on #4 sieve) 5 percent Maximum Large Shell Content (retained on 3/4 inch sieve) 1 percent Moist Munsell Color Value (greater than or equal to) 6 value Mean Grain Size Range 0.35 to 0.65 mm

The compliance values described above refer to the average values assessed over a 10,000 square-foot area of the placed fill material. Material which exceeds the compliance values listed in Table 1 and which exceeds the natural occurrence within a 10,000 square-foot area, will be classified as noncompliant.

3.7.2 Beach Fill Observation and Sampling

Beach fill observation and sampling shall be performed during construction to ensure that the beach fill material meets the compliance criteria.

a. Beach fill observation shall be performed at all times during which beach fill material is being placed. The Contractor shall have on-site personnel to visually monitor the material being placed on the beach and who can identify obvious changes in beach fill quality at the active placement location. The selected individual shall have training or experience in beach nourishment, construction inspection and testing and be knowledgeable of the contract requirements.

b. The Contractor shall conduct assessments of the beach fill as follows: The Contractor shall collect a grab beach fill sample for every 200 linear feet of constructed beach to visually assess for compliance criteria. Each sample shall be archived with the date, time, and location of the sample. The sample shall be visually compared to the compliance criteria provided in Table 1. All samples shall be stored until project completion.

c. Should any beach sample not comply with the compliance criteria stated above, the Contractor shall notify the Contracting Officer at the first available normal business hour. Should three (3) consecutive beach samples not comply with the compliance criteria, the Contracting Officer shall be notified immediately and the Contractor shall cease transporting from the upland borrow source(s) and take necessary actions to avoid further placement of noncompliant material with possible remediation. The Contracting Officer will then advise the Contractor how to adjust the construction operation at the borrow area to avoid placing additional noncompliant material.

d. If requested by the Contracting Officer, the Contractor shall take the collected beach fill for analysis of grain size distribution, Munsell color, carbonate content, and percent visual shell by a certified laboratory. Gradation analysis shall be performed according to ASTM D422. U.S. Standard sieve sizes shall include 3/4 inch, 3/8 inch, and numbers 4, 7, 10, 14, 18, 25, 35, 45, 60, 80, 120, 170, 200, and 230. The results shall be sent to the Contracting Officer within two (2) weeks.

3.7.3 Determination of Areal Extent of Noncompliant Beach Fill

In order to determine if an area greater than 10,000 square feet of beach

SECTION 35 30 00 Page 16 fill is noncompliant, the following procedure shall be performed:

a. Upon determination that the first beach fill sample is noncompliant, at minimum, five (5) additional beach fill samples shall be collected at a 25-foot spacing in all directions and assessed. If the additional samples are also noncompliant, then additional samples shall be collected at a 25-foot spacing in all directions until the areal extent is identified.

b. The samples shall be visually compared to the compliance criteria. If deemed necessary by the Contracting Officer, quantitative assessments of the samples shall be conducted. All samples shall be stored until project completion.

c. The total square footage and volume of the noncompliant material shall be determined and a site map shall be prepared depicting the location of all samples and the boundaries of all areas of noncompliant fill.

d. The Contracting Officer shall be notified. Notification shall include the map with the areal extent and volume of all areas of noncompliant beach fill material.

3.7.4 Remediation

If the Contracting Officer determines remediation is required, the Contractor shall remediate. Methods of remediation may include, but are not limited to:

a. Blending of noncompliant material (i.e. when exceeding compliance values listed in Table 1 for silt, fine gravel, shell, or Munsell color) with compliant material to achieve a sand mixture that acceptably complies with the compliance criteria.

b. Excavating unacceptable material such as construction debris, toxic material, or other foreign matter, disposing of the material, and replacing the material with sand that complies with the compliance criteria.

c. Screening unacceptable materials such as rocks greater than 3/4 inch or clay balls from the fill and disposing of the material.

d. Notwithstanding the above, burial of noncompliant fill within the existing beach or beach fill is not permitted.

All material to be disposed shall be hauled off site to a disposal area obtained by the Contractor and approved by the Contracting Officer.

3.7.5 Noncompliant Material Contingency Plan

The Contractor shall be responsible for establishing a contingency plan in the event that noncompliant materials are encountered. The contingency plan shall be submitted to the Government for information purposes only.

The contingency plan shall include but is not limited to the following:

a. How the Contractor plans to notify the Contracting Officer if noncompliant materials are encountered.

b. How the Contractor will report any encounters with noncompliant

SECTION 35 30 00 Page 17 material in the daily quality control reports, such as approximate elevation and horizontal position (in project reference datum) where the materials were encountered, as well as the location where material was placed in the beach fill template.

c. Who will conduct the laboratory analyses and how they will be conducted if requested by the Contracting Officer.

d. If three (3) consecutive beach samples do not comply with the compliance criteria, briefly explain how control measures will be established to adjust placement operations and avoid further placement of the noncompliant material.

e. If remediation requires blending, excavation, or screening of noncompliant material, describe how the remediation operations will be accomplished.

3.8 INSPECTION

3.8.1 Quality Assurance Representative (QAR)

The QAR shall be notified prior to the establishment of horizontal control work (baseline layout, ranges, station flags, shore-based control for EPS/RPS, etc.) and vertical control work (tide staff(s), upland cross sections, and construction elevations top/invert), but the presence or absence of the QAR shall not relieve the Contractor of his responsibility for proper execution of the work in accordance with the specifications.

3.8.2 Failure to Comply

In conjunction with the Clause INSPECTION OF CONSTRUCTION of Section 00700 CONTRACT CLAUSES in Volume 1, should the Contractor refuse, neglect, or delay compliance with these requirements, the specific facilities may be furnished and maintained by the Contracting Officer and the cost thereof will be deducted from any amounts due or to become due the Contractor.
