From the roof to the ground, most of the sewer and drainage lines outside the renovated bathrooms need to be exposed (visible). In these cases, the contractor shall install the pipes as close as technically possible to the walls and ceiling surfaces, and the lines shall be painted with the same color as these surfaces. Pipes shall be painted before they are installed to maximize the quality of the paint application.

The replacement of the sewer and drainage lines of areas not under the scope of work of the contract is technically challenging. The contractor shall need to remove many appliances, and to reinstall them after the new sewer/drainage lines are installed. This will require replacement of some elements which will not be able to be reinstalled, as for example the floor drains. The contract includes the replacement of all floor drains.

Extensive damages are estimated on the walls, and especially on the floors, which the contractor shall restore to their original condition, to the maximum extent technically possible.

The replacement of the sewer and drainage lines includes the replacement of the roof drainage pipes that run inside the Southern building. This contract does not include roof repair, and therefore the contractor shall connect to the existing roof drain immediately on the ceiling of the second floor.

The contractor is responsible to replace the pipes from the roof, including the roof floor drain, only if these are altered, modified or damaged due to their work on the second floor.

3.2.2 Replacement of Sewer Lines in the Patios

The contract includes a completely new design for the sewer lines in the patios. Currently there are two sewer lines crossing under the hallway that separates the two patios. Once the contract is completed, there shall be one single sewer line under this hallway.

The contract does not include cutting any tree, which may affect the routing of the new sewer lines.

If any tree needs to be cut or pruned, the contractor shall coordinate with the beneficiary its removal or pruning. The contractor shall give a minimum of one month advance notice to the beneficiary, for them to be able to coordinate with the corresponding Municipal authority responsible for such work.

3.2.3 Replacement of Sewer Line along the Mechanical Room

The sewer system of the Southern building collects all the sewer/water in the patios, and from the patios it goes outside the building through the mechanical room. The new sewer line crossing under the existing building needs to collect the drainage from the boiler room, including sinks and floor drains. This section of piping may need to be metal, if adequate coverage or protection is not feasible.

3.2.4 Replacement of Sewer Line Outside of the Building

The contract includes the replacement of the sewer line from the first manhole outside the Southern building, to the manhole where the Northern building sewer connects to. This last manhole shall be cleaned, repaired and provided with internal plaster on the walls and floor, using special waterproofing material. The contract does not include the replacement of any tree that may interfere with the routing of the new sewer lines. If any tree needs to be cut, the contractor will coordinate with the Kindergarten Director and Municipal authorities with at least one month advance notice.

Section of Exterior Sewer to be replaced

New sewer lines shall be minimum of 250 mm internal diameter, unless a bigger size is required by Bulgarian regulations or the contractor’s certified design. The contractor shall install the new sewer line parallel to the existing one, and then abandon in place the old sewer line, after capping it at both ends. Old sewer manholes to be filled with dirt and the top removed, so that there shall be no evidence of the old manholes once the project is completed.

Similarly to the work inside of the Southern building, the contractor is responsible to restore all paved and green areas outside of the building to their original condition. This includes among other elements, exterior concrete pavement or an exterior gazebo that may be in the way of the new sewer lines. In this case, the contractor would be responsible to remove the gazebo, store and reinstall once the works are completed. Similarly to the work inside the building, the contractor is responsible to make a picture report with the original exterior conditions, in order to be able to restore to the original conditions.

Replacement of the last manhole where the new sewer lines will connect to is not included in the contract. However, this last manhole shall be properly cleaned and provided with new internal special waterproofing plaster.

Hallway to be crossed by new sewer line. Floor surfaces to be restored to the original conditions to the maximum extend technical possible.

It must be noted that these areas were not designed to be used as a gymnasium for young children, but they were designed for industrial purposes. In general, all areas shall be completely renovated.

4.1 Flooring

All flooring in the renovated areas, including the entire second floor and the ground floor lobby shall be provided with new flooring surfaces.

The contractor shall provide porcelain stoneware tiles and homogeneous vinyl as described herein. All floors in the second floor shall be provided perfectly leveled and at the same elevation, except in the bathroom where they shall be sloped towards the new floor drains.

4.1.1 Grès Porcelain Stoneware Tiles

On the red highlighted areas of the drawing above, and in the ground floor lobby, including the stairway, the contractor shall provide new grès porcelain stoneware tiles. Include matching wall base board from the same model as the tiles.

BU-HA-2014-20283 Page 34 of 142 Version: 001

Picture#58: Typical grès base boards

Grès Porcelain stoneware is a ceramic with a compact, hard, colored and non-porous body. The word “grès” means that the ceramic body of the tile is extremely vitrified, that is to say compact, hence the exceptional great resistance. The result is a lean clay body, little refractory, fired in a kiln (at 1200-1400 C°) until it reaches a non-porous vitrification and a complete water-proofing.

The new ceramic tiles shall be high quality, provided with the following technical features:

- Water Absorption: Tested by ISO 10545 - 3 ≤ 0,5%

- Deep abrasion resistance: Tested by ISO 10545 – 6: Max 175 mm3

- Frost resistance: Tested by ISO 10545 – 12: Tiles must not produce noticeable alteration to surface

- Chemical resistance: Tested by ISO 10545 – 13: Tiles must not produce noticeable signs of chemical attack

- Friction coefficient (slipperiness): Tested by ASTM C 1028 ≥ 0,60

- Size: Minimum 45x45 cm

All floors shall be perfectly leveled, at the same height as the new required homogeneous vinyl flooring. In the bathrooms, all floors shall be sloped towards the new floor drain to be provided as part of this contract.

The contractor shall completely remove the existing flooring surfaces, as necessary for the leveled installation of the new flooring surface, and shall follow the same steps as for the linoleum flooring in order to provide the finished surface to the right elevation. Tile installation shall be done following manufacturer’s instructions and recommendations.

The new porcelain gres tiles shall be minimum 30x30 centimeters, and the ceramic tiles shall be installed diagonally with respect to the walls.

Gres Porcelain Stoneware for the Stairway:

On the stairway, the contractor shall cover all surfaces with porcelain stoneware grès tiles, similar to the other horizontal surfaces.

However, for the stairway, the contractor shall provide special tiles designed to be used in stairways, or provided with special anti-slippery stair edges (normally called “stair nosing”). The use of regular tile corner/edge protection is not authorized. See pictures in next page for examples of what is acceptable and what is not acceptable for the stairway finishes.

The contract includes covering all surfaces of the stairway with new tiles, including the horizontal and the vertical surfaces of each step.
