Who owns the land?
Who uses the land (formal/informal)?
Land plot under and around the Telavi former Medical Dispensary is registered as a property of Telavi Municipality.
SP does not imply of private land use and no permanent impacts are envisaged on private or leased agricultural lands and private assets or businesses.
Description of physical and natural environment
around the site
The building to be rehabilitated is located in a self-governing city Telavi, #11, Rustaveli ave Premise allocated for the RIH are situated in the Kakheti region, eastern Georgia. It’s possible to access this place using Tbilisi-Sagarejo-Bakurtsikhe-Telavi (distance 150 km) and Tbilisi-Gombori-Telavi (distance 88 km) motor roads.
The town is located on the north-east slope of the Gombori Range, on the open plain Alasani Valley, at an altitude of 550-800 meters. It is characterized by a humid climate, with hot summers and mild winters. Annual precipitation is up to 794 mm. The average temperature 0,5°C is during the coldest month - January and in July it is 22,9 °C. The town is situated at the entrance to the Pankisi Gorge. The population of the city is 19,629, according to the census of 2014.
In the town, there are industrial enterprises, health care, educational and cultural institutions.
The Telavi former Medical Dispensary was constructed in the 1940-ies. In 2010 on building were performed reconstruction works, in particular: the façade was rehabilitated, foundations were reinforced; the roofing - replaced; communication network - renewed the; and the yard was landscaped. Currently the object is on the balance of Telavi city hall and is not operational.
The SP will have significant long-term positive social impact. The negative impacts on the natural and social environment; in particular: increased level of noise, dust, vibration and emissions from the operation of construction machinery, generation of construction and domestic, increased traffic flow and safety risks for pedestrians, will be short term and limited to the construction site.
The building is a 2-storeyed construction, built on the 1286 m2 area. Total area makes 484.80 m2. The placement of the RIH is planned on total area of the building.
According to the examinations of LTD “SMM” the building under the study with dimensions 12.0m×24,0m, is two-storied without basement that is built of strip, pebble-stone foundation (deepening 1.40m, width 1.0m). The brick-works walls are 0,80m in thickness and floors are arranged with timber structures. The building is supported on gravelly clay loam-, developed from alluvial and proluvial deposits. On foundations of building and surrounding territory are not observed any signs of dangerous engineering-geological processes. The building of former medical dispensary (cad. code of plot № 53.20.37.143) and its surrounding area in terms of geological engineering is in stable conditions and development of dangerous geological processes is not expected. In order to avoid development of negative impacts on the integrity
of the building in the future, as a result of environmental factors, it is necessary to periodically (twice in year) clean the drain for avoiding of atmospheric precipitates penetration in foundations.
The facade and the roof of the building do not need rehabilitation.
Currently the building is not functioning and the project does not provide a constructive scheme for the building and only includes facing works.
Consequently, the activities defined by the project will not cause any negative impact on the condition of the building.
Locations and distance for material sourcing, especially aggregates,
water, stones?
Power and water supply of the building is carried out from the existing local networks.
The closest sand and gravel pit is located in 7-8 km from the site.
The nearest local official non-hazardous waste landfill is located in town Telavi. The distance from the project site is 10 km.

Chapter II. Technical expertise conclusions-recommendations
The object under study presented by customer before specialists group of LTD “Structural integrity
monitoring” (accordingly of objective) is located in №11, Rustaveli av., Telavi, Georgia represents
two-storey building of former medical dispensary (Cad. code of plot № 53.20.37.143).
In terms of time resources the existing building was constructed in the 40-ies of past century.
Prior to restoration in 2010 the building under study was functioning as a medical center. For
period of presented examination it was applied for organization of exhibitions. Due carried out
visual monitoring and instrumental examination was determined the following :
2.1. In engineering-geological terms
two-storey building of former medical dispensary located in №11, Rustaveli av., Telavi, Georgia
(cad. code of plot № 53.20.37.143) and its surrounding area in terms of geological engineering is
in stable conditions and development of dangerous geological processes is not expected.
In order to prevent development of impact of negative environmental factors in the future, it is
necessary to clean periodically (twice in year) the drainage network for avoiding of atmospheric
precipitates penetration in foundations.
2.2. In point of geodetic view
The deviations of mentioned building’s corners and outer walls from vertical is in permissible
range and are not dangerous for their stability state.
2.3. Auxiliary installation
On the back-side territory of building is arranged open-type installation with suspended
inclined ceiling. It’s load bearing structure consists from metal hollow rectangular shapes. On
these elements does not observed deformations. As walls fillers is presented small construction
block work 20 cm in thickness. On the mentioned walls are observed vertical orientation
significant range cracks. In necessary in the areas of mentioned cracks removal of plaster,
arrangement of interconnected two-sided standard metal mesh, plastering with high strength
sand-cement mortar (M200) and painting with similar to adjacent area paint.
2.10. Conclusion:
The building under study, as it was above mentioned, was constructed in 40-ies of past century
and corresponds to magnitude 8 seismicity requirements (accordingly of acting at that period
seismic zoning town Telavi belongs to magnitude 8 seismicity zone). As it was mentioned in
examination part, in 2010 on building were performed reconstruction works, in particular, were
concreting the existing pebble stone foundations; were arranged the seismic belts on floors, were
arranged reinforced concrete elements on thresholds of openings, was replaced the roofing; was
renewed the communication network; finally on building were arranged facing works. On the
territory of building was arranged open type water accumulation drainage.
Proceeding from above mentioned located in № 11, Rustaveli str., Telavi, Georgia (cad. code of
plot № 53.20.37.143) building of former medical dispensary is statically and sesmically in stable
state. It satisfies the current requirements of building on seismicity (above 8 up to 9 magnitude in
accordance with “Earthquake proof construction” (PN 01.01-09) Chapter 1, clause 3, paragraph
14). Due the taking into account above mentioned factors is possible on building to carry out
necessary for further operation rearrangement of floors.
As a note, we can say that the building under study as floors has arranged in the timber beams
with boarding. In the case of on building floors will be necessary the installation of technological
equipment the timber floors will be replaced with monolithic reinforced concrete slabs and
reinforced on the basis of the foundations calculation.
