SPECIFICATIONS

This Specification establishes the County's minimum standard for precast modular wall block units.

FINISH AND APPEARANCE

All units shall be sound and free of cracks or other defects that interfere with the proper placement of the unit or significantly impair the strength or permanence of the construction.

The texture of units shall be Weathered Edge, as manufactured by Recon Wall Systems, or equivalent. The finished surface that will be exposed in place shall conform to an approved sample consisting of not less than four units, representing the range of texture and color permitted.

SAMPLING AND TESTING

The County, or authorized representative, shall be afforded the opportunity and proper facilities to inspect and take concrete samples (cylinders) from the actual units to be fabricated for purchase by the County at the time and place of manufacture. The County reserves the right not to accept existing units from stock for this project, and to receive only units cast specifically for this project. If the County agrees to accept units from stock for this project, the Supplier shall provide all necessary testing reports, including concrete mix designs and testing / strength reports to validate the units’ conformance with specifications.

Retaining wall block units shall conform to the following:

1. The block units shall consist of concrete with the average 28-day compressive strength of no less than 4000 psi.

2. Concrete shall have air entrainment by volume (as measured in the plastic state in accordance with ASTM C172) of:

a. 5.5 – 8.5 percent, or

b. In conformity with ASTM C94, latest revision.

3. Exterior dimensions of the face shall be 48-inches by 16-inches for full and corner unit, and 24-inches by 16-inches for half unit.

4. Depth and type of unit shall be in accordance with blocks manufactured by Recon Wall Systems, or equivalent. Depths include 24”, 39”, 60”, 66”, and 72”.

5. Block units used shall maintain tolerances of:

If the second sample meets the specified requirements, the remaining portion of the shipment represented by the sample meets the specified requirements. If the second sample fails to meet the specified requirements, the remaining portion of the shipment represented by the sample fails to meet the specified requirements.

TECHNICAL SPECIFICATIONS P. 4 OF 5

All insurance required herein shall be maintained in full force and effect during the term of the successful Respondent’s Contract with the County and shall constitute primary coverage over any other applicable insurance.

The County may from time to time dependent on the “scope” of services require coverage, limits and conditions unique to the type of work, scope and size of the contract. Approval and terms shall be reviewed/proposed by the County Risk Manager and the Administration.

The successful Respondent shall furnish a Certificate or Certificates of Insurance in compliance with these requirements and upon request a certified copy of each policy to the County, including the provisions establishing premiums. All insurance policies required hereunder shall include an endorsement naming the County and its officers, agents, engineer, attorney, employees, and servants as additional insured’s, which insurance shall provide primary and non-contributory insurance coverage to the County of Sussex, its departments, agencies, boards, commissions, officers, agents, servants, administrators and employees.

In addition, the additional insurance shall include but not be limited to coverage for the additional insured for bodily or personal injury, property damage or other loss for which the successful Respondent’s insurance policy provides coverage for the successful Respondent’s work and for coverage, which is included in the successful Respondent’s “products-completed operations hazard” coverage.

Insurance coverage having policy limits in the amounts required by the County shall not be construed to relieve the successful Respondent from liability in excess of such coverage, nor shall it preclude the County from taking such other actions as are available to it under the provisions of this Contract or otherwise in the law.
