2.10 UTILITIES

This section applies to all project underground utilities located outside the building, including but not limited to, sanitary sewer, water supply, storm drainage, electrical, communications, and heat. See Sections 5.0-ELECTRICAL, and Section 6.0- MECHANICAL for additional utility requirements.

Install newly required utility main alignments at least 3.0 meters from facility or building foundations, except for building connections. Provide horizontal and vertical separation between relocated and existing utilities for rehabilitation, maintenance, repair or replacement. Provide utility line depths, bedding, and backfill as required by applicable requirements and geotechnical recommendations.

Minimum cover over pipes is 0.6 meters; greater than frost penetration; or sufficient to support imposed dead and live loads for the pipe materials used; whichever is more stringent. Place plastic warning tape along the route of the buried pipe after installation at a height of 0.3 meters above the pipe.

Coordinate all required relocation, improvement and protection of utilities held by third party (e.g. public or private utility). This includes coordination of any work to be performed by the utility owner. Choice of materials and products for utility installation must be coordinated with the utility owner (customer or third party) to ensure proper integration and compliance with existing systems and allow for easy maintenance and repair of the utilities in the future.

Provide utility materials per IBC requirements. Provide corrosion protection for utilities that provides the minimum life expectancy specified in GENERAL Section

1.0. Any piping or equipment exposed to sunlight must be coated with protective coatings suitable for UV exposure with a minimum expected coating life of 10 years before recoating.

2.10.1 STORM SYSTEM

Provide positive site drainage to direct runoff away from the existing Housing Unit and the planned improvements, eliminate ponding, and prevent erosion. Take maximum advantage of existing drainage patterns and systems. Include gravity collecting and conveyance systems like open channels, and pipe systems, as needed to preclude adverse impact on planned and existing facilities on site and on adjacent properties.

Direct run-off to the closest applicable legal point of discharge, or convey storm water into adjacent terrain provided that adverse impact on downstream facilities is precluded and HN regulations allow for this. Provide detention or infiltration systems as required to control flow and keep run-off on site. Employ sustainable storm water management practices like infiltration facilities as far as geotechnical conditions allow.

21-May-19 Page 15 of 52

If using an infiltration or detention system, locate infiltration/detention facilities a minimum of 3 meters away from structures. Provide an overflow to the infiltration/detention system that will not damage improvements or cause erosion.

Provide a French drain system around the Housing Unit and the new stairwell to keep run-off and seepage water away from the foundations since the flat site will not allow for sufficient grading needed for effective site drainage. Provide a pump system if the French drain system cannot be connected to the next point of discharge using gravity flow. Connect the French drain system to an effective infiltration system instead of using a pump system if geotechnical constraints allow.

Connect building downspouts to infiltration features or to splash blocks that drain away from foundations a minimum of 1 m.

Storm structures must be concrete, with traffic rated cast iron or ductile iron frames and covers. In the absence of Host Nation standards, design the storm drainage system per the IBC.

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

Connect the new sanitary systems of the Housing Unit to the existing municipal sewer system running in close vicinity to the building. 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 further details.

2.10.3 WATER SYSTEM

Provide a water system to connect the new utility room of the Housing Unit to the existing municipal water system running in close vicinity to the building. Design the system to meet all flow requirements of the facility, including potable water and fire flows. In the absence of Host Nation standards, design the water system per the IBC.

After installation, test water supply lines according to local codes for leakage.

Before the water supply line is put into final operation, disinfect the line, and then flush the line to remove traces of the sterilization agent. Test treated line for coliform bacteria. 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 further details.

2.11 PAVEMENT

Provide site access for pedestrians to all building entries to allow for operational and maintenance access to the facility. This is to include accessible routes to the three (3) building entries that need to be handicapped accessible as per architectural requirements (see Conceptual site layout on Attachment#1 and

21-May-19 Page 16 of 52

Attachment#3 – Functional Building Layout). Provide the handicapped accessible routes to consist of Portland cement concrete (PCC) walkway connections to the existing roads with a width of minimum 1.8 m, wheelchair ramps of minimum 1.2 m width as well as exterior stairs and stoops made of PCC.

In the absence of Host Nation standards, design pavements per UFC 3-201-01, Civil Engineering and pedestrian access, accessible stairs and wheelchair ramps per ABA Guidelines.

Install a perimeter apron around the Housing Unit and the Stairwell with minimum 1 m width and minimum 2% cross slope directing run-off away from the exterior building walls. The perimeter apron shall be either made of tiles or PCC pavement.

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 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.
