Tenders Are Invited For Modernization Of The Boiler Room In Public Buildings

Description: The Study Includes A Project To Rebuild The Existing Fuel-Fired Boiler Room For A High -Man-Burned Earth Gas Boiler Room Together With The Reconstruction Of The Central Heating, Water And Sewage And Electrical Installation As Well As Modernization Of The Ventilation System And The Use Of A New Installation Fitting Technical Standards And Safety Regulations. The Technology Of The Designed Boiler Room Should Be Made Based On A Gas Condensing Boiler With A Closed Combustion Chamber With A Nominal Capacity Of Qnom - Central Heating 24.0 Kw, Cwu 29Kw. The Designed Boiler Will Cooperate With The Designed Standing Container Of 290 -Liter Hot Water With An Additional 3Kw Electric Heater. For The Installation Of Hot Utility Water, Use A Thermostatic Mixing Valve With A Temperature Range Of 35 Degrees C - 60 Degrees C. Central Heating Installations Will Take Place Through The Dn28/Cu. Temperature Pipe. Temperature Recreation For Central Heating Circuit Will Provide External Temperature Sensor And A Room Thermostat. The Heating Installation Within The Boiler Room Should Be Combined By Soldering. The Work Includes The Following Stages: 1. Preparatory And Disassembly Work. Preparation Of The Construction Site, Securing The Boiler Room. Demontoration Of An Existing Cast Iron Boiler, Fittings, Water Heaters, Pipelines And Electrical Devices. Removal And Disposal Of Debris And Dismantled Installation Components. 2. Construction Works Of Floors And Plasters At The Place Of Installation. You Will Connect The Holes In The Walls And Ceilings For The Needs Of The Installation. Completing New Floor Layers And Plaster After The Installation Works. Painting Walls And Ceilings, Assembly Of New Windows, Terracotta Tiles And Tiles. 3. Installation Of The Boiler Room And Central Heating The New Condensing Gas Boiler With Automation And Circulation Pumps. Mounting Of The Hot Water Tank, Expansion Vessel And Fittings (Valves, Filters, Pressure Gauge, Thermometers). Conducting Installations Stainless. Cleaning And Preparation Of Chimney Flues. 4. Gas Installation Installation Of New Copper And Steel Gas Pipelines. Installation Of Gas Equipment (Gas Stool, Gas Stove). Performing The Tightness Of The Gas Installation. 5. Water And Sewage Installation. Installation Of Water And Sewage Cables With Fittings (Valves, Siphons, Sewage Inlets). Connection Of Sanitary Facilities. Tightness Tests And Installation Of The Installation. 6. Electrical Installation Disassembly Of The Old Electrical Installation In The Boiler Room. Performing A New Electrical Installation For The Needs Of The Boiler Room (Wires, Sockets, Switchgear). Installation Of The Gas Detection System And Alarm Devices. Installation Of Boiler Room Lighting And Connecting Electrical Devices. 7. Starting And Testing Tightness And Adjustment Of Central Heating Installations. Starting A Gas Boiler Room With Automation Setting. Performing Electrical Measurements And Checking The Operation Of The Gas Detection Sys
