Temporary measures, for protection of Pipelines from washout, have been designed at the river Shamkirchai and permanent measures are in the stage of designing. Designing includes arrangement of concrete and riprap barrages, arrangement of river bed revetment structures by means of riprap.
Conducted works comprise the following:
- Arrangement of Wind Turbine Foundations and Cable Ducts at Block Valves 03 and 16 of BTC Pipeline.
- Fence Repair Works at Block Valves 15 and 16 of BTC Pipeline.
- Arrangement of Reinforced Concrete Trackways for Turbine Removal at PSG 1 and PSG 2.
Works include detailed design as well as construction.
Works consist of:
- Earth works, ditch arrangement around the site, area fencing, internal road arrangement, concrete sidewalk arrangement, area landscaping.
- Bedroom facility/connecting hallway and kitchen-dining facility construction (with total area 1020,8 sq.m.). These activities included construction of the foundation, foundation slab, columns, beams and ceiling slab with the r/c structures; also, arrangement of walls and partitions with various materials, their plastering and painting, winterization (warmth-keeping) of the foundation. Arrangement of steel trusses and purlins, roofing of buildings with galvalume-coated metal materials. Buildings were furnished with metal plastic windows, metal doors, iron-framed wooden doors, metal plastic doors and etc. Arrangement of indoor electrical system; outdoor security lighting, water supply, sewer system, heating, ventilation, security CCTV system, fire alarm system.
- Generator and fuel storage shelter construction
- Arrangement of chiller/freezer shelter
- Arrangement of STP and its respective reed-bed.
Works included arrangement of magnets at the top of the pipelines and their planning in absolute coordinates. In total 38 magnets have been arranged. Besides this, temporary monuments have been arranged alongside the pipelines.
In Bakuriani region, pouring of reinforced concrete on the parapets of Secondary Containment Structures arranged on the rivers: Tskhratskaro, Kumiska-1, Kumiska-2, Oshora-1 and Oshora-2 and in the foundations of three generators (356m³). Construction of storage places for three generators; provision of facing works in them.
Arrangement of 7343m³ gabions at the banks of the aforementioned rivers.
For installation of four wind turbines at BV16 and GB03 following works were done - topographical survey and geotechnical investigations of sites, calculation of bearing capacities of turbine foundations, rehabilitation of access roads, preparation of construction sites, installation of foundations of turbines and winch anchors with reinforced concrete, installation of cable ducts.
Works included arrangement of monuments alongside the pipelines and their planning in absolute coordinates. In total 203 monuments have been arranged.
Topographical and geotechnical surveys have been conducted; there have been designed reinforced concrete foundations for STP facilities and concrete surroundings, reinforced concrete intake and discharge manholes in the reed-bed according to the given dimensions, also pipelines from STP facilities to the reed-bed and from the reed-bed to the existing ravine. Layout schemes for STP facilities have been determined. Construction process included installation of necessary STP equipment (RBC Unit, Twin Effluent Pump Station, UV Chamber and Mag Flow meter) on the pre-arranged reinforced concrete foundation and placement of these equipment in the concrete slabs. Also, construction of reed-bed.
Beds of all three rivers and their banks were fortified by means of 0, 7-1,0m size riprap. In total, 1400mі of riprap have been arranged on all three rivers.
Area topographical survey and geotechnical investigation. Permanent Accommodation Area consist of the following facilities: bedroom facility for 24 persons, kitchen/dining facility, guard house, generator enclosure and fuel storage shed, sewage treatment plant, smoking shelter, waste segregation area, outdoor recreation area, parking area, court. The work included the following designs: area vertical planning architectural, structural, indoor electrical system; outdoor security lighting, water supply, sewer system, heating, ventilation, security CCTV system, fire alarm system etc. For the design were applied local standards as well as British Standards, IBC-2000, NFPA 101.
