The Contractor shall also similarly grade the soil subgrade before pavements, foundations, or concrete pads are installed, in order to keep the subgrade sufficiently dry until pavement or foundation work is complete.

All depressions and low areas within the project site shall be filled and brought to grade. The final site shall be graded to provide a uniform surface over the entire site with no abrupt changes in grade due to depressions or embankments. The Contractor shall take into account the annual wet and rainy periods and shall perform site grading such that there is no erosion or undermining of the fill areas for the new building and its associated exterior features.

2.6.7. STORM DRAINAGE

The Contractor shall provide the most appropriate drainage system for the site, in accordance with host nation and local government regulations. The Contractor will take into account the information gathered from the previous site design, local climate and rainfall data, 10 year return storm frequency, and any other relevant information/data.

Storm drainage systems shall be designed to carry storm water away from structures and pavements by channel, piping, or sheet flow. The storm drainage system will be designed for a 10-year return storm frequency so that the likelihood of ponding around the building, or elsewhere on the project site, is minimized. Below each downspout outlet provide a splash block that will drain water away from building foundations a minimum of 3 meters per site grading requirements.

2.6.8. UTILITY LINES - GENERAL

The intention of this scope is that the project will reuse existing connection points for all utilities. The Contractor shall verify the condition and capacity of any existing exterior utilities which will be affected by this project. It is the Contractor's responsibility to confirm the specific location, depth, capacity and condition of the existing utilities and to construct and install any new required utility services for the project facility.

The COR shall be notified of any utility lines found to be missing from or incorrectly shown on any existing plans showing existing conditions and made available to the Contractor. Any indication of existing utility lines on such plans shall not mean the existence, location, depth and/or alignment of the lines is accurately represented. The Contractor is responsible for the protection of those lines that are to be kept in operation.

2.6.8.1. WATER SUPPLY

The Dapaong Hospital has an existing water supply to which the new laboratory addition will reconnect.

After installation, the waterlines shall be tested according to local codes for leakage under pressure. Before the waterline is put into final operation, it shall

27-Jun-19 Page 13 of 46 be disinfected in accordance with local standards and then flushed through to remove traces of the sterilization agent. The line shall not be put into operation until absence of coli form organisms is proven by a bacterial examination of the treated line by a local medical service. The results of both tests shall be provided to the COR and, if the test results are unsatisfactory, necessary remedial work shall be at the Contractor’s expense.

2.6.8.2. WASTEWATER SYSTEM

The Dapaong Hospital has an existing waste water septic system to which the new laboratory replacement will connect. The Contractor will reuse connections utilized by previous laboratory structure.

2.6.8.3. BURIED ELECTRICAL CABLES

Where proposed electrical utilities cross existing or proposed ditches, the cables shall be buried to a minimum depth of 30 cm below the ditch/swale bottom. Where cables are required to cross concrete walls, cables shall be installed in a steel conduit below the wall foundation. If a wall foundation extends 1 m or more deep, the foundation may be cored and fitted with a PVC sleeve to allow passage of cables through it. The PVC sleeve size shall be coordinated with the COR.

2.6.9. LANDSCAPING

The Contractor shall provide a plan indicating the location and limits of areas to be restored and/or repaired which were damaged by the contractor’s work effort.

Restoration plan will include, at a minimum, a plan for re-establishment of ground cover consistent with the surrounding area. These items shall be indicated on the new site plan.
