4.1 Crack Repairs – Thermally Insulated Facade

The kindergarten building was surveyed and evaluated by the Chief Architect of Targovishte in February 2018. The Chief Architect confirmed visible cracks on the façade walls 1 to 4 mm width.

She concluded that those cracks result from the soil compaction process occurring beneath the building foundations and that at the present moment those processes have completely subsided over the course of 50 years of the building exploitation period. In addition to the façade cracks, a much larger diagonal crack in the southwestern part of the building, located to the left of the main entrance, in the section between the two windows belonging to the boiler room and the storage room. This same crack was found extending to the aboveground floors: in the rooms on the ground and second floors. This problem occurred as a result of compromised drainage of water from the roof, which was repaired in 2006 with the replacement of the waterspouts and gutters in the entire building.

The contractor shall hire the services of specialized and licensed architect in Bulgaria to design, supervise and certify the crack repairs in compliance with Bulgarian regulations and following the general guidelines provided herein.

This contract includes in general terms:

- Remove all loose plaster with high pressure water blasting. Contractor shall estimate that this the required water blasting method, approximately 80% of the plaster will be removed.

- Notify the Chief Architect in Targovishte 2 working days before plaster removal for her to inspect the cracks and the contractor’s proposed repair method.

- Provide new reinforced leveling plaster after repair of cracks

- Notify the Chief Architect in Targovishte 2 working days before completion of the crack repair. The thermal façade installation shall not start on any section of the façade until the Chief Architect in Targovishte has had the opportunity to inspect the crack repairs with two days in advance notice.

- Apply thermal insulation façade system

- Provide new gutters and downspouts

- Provide continuous exposed natural stone on the lowest section of the façade, matching existing

Removal of plaster and paint and inadequate concrete

The contractor shall use high pressure water blasting at minimum 100 bars to remove all poorly attached plaster from the building. This high pressure water blasting will also remove all the paint and any defective masonry, plaster and concrete elements. It is estimated that minimum 100% of the paint and 80% of the plaster will be removed by means of this required high pressure water blasting.
