2.2.1 TOPOGRAPHY

There is no known topographic survey for the project site. The site contains the existing Kindergarten building, a gazebo, pavement, utilities, fencing, and vegetation as shown in the Conceptual Site Plan on Attachment #1.

After installation, test storm lines and structures for leakage and deflection per local codes. Provide test results to the COR. Locate and repair any sections failing to pass the required tests. Repeat the specified tests and inspections on the repaired sections.

2.10.2 SANITARY SYSTEM

Provide a sanitary system that connects the building to the existing holding tank.

Repair the existing holding tank including piping, and all appurtenances to meet sanitary and environmental requirements as per local codes.

In the absence of Host Nation standards, design the sanitary system per the IBC.

After installation, test sanitary lines and structures for leakage and deflection per local codes. Provide test results to the COR. Locate and repair any sections failing to pass the required tests. Repeat the specified tests and inspections on the repaired sections.

See SOW Section 6.0 – MECHANICAL for indoor sanitary scope.

For asphalt concrete, provide compaction and pavement density tests, as well as thickness and evenness tests, at the frequency listed in Section 2.9 - EARTHWORK.

For PCC, reference SOW Section 4.0 - STRUCTURAL for concrete requirements. Perform subgrade tests for all pavements as described in Section 2.9 - EARTHWORK. The location of all tests must be selected by the Contractor’s Geotechnical Engineer, and copies of all test results must be furnished to the COR.

2.12 FENCE

Provide a minimum 1.5 meter high chain link fence around the perimeter of the property as shown in the Conceptual Site Plan on Att# 1.

2.13 LANDSCAPING

Provide grass seed and 20 centimeters of topsoil on the site in areas that do not have pavement or a building within the limits of disturbance. Seeds must be locally sourced, and native to the area. Provide seed coverage density per manufacturer/ supplier’s recommendations. Provide watering, weeding, and any other necessary care to establish growth. Limit planting to times of the year per local codes and/or manufacturer/supplier’s recommendations. Replace topsoil and seeds, at Contractor’s expense, in areas which do not have new growth coverage of 75% before the warranty period ends.

Before using chemicals during landscaping work, including for use on plants and on site features, the Contractor must submit to the COR, in the form of brochures, certificates and other technical material, information about the chemicals proposed, including about their environmental compatibility. Their use is only permitted with approval of the COR.
