Work Detail

The Subject Of The Order Includes The Implementation Of The Following Main Activities:1. Design In Phase Technical Design;2. Performance Of Construction And Installation Works, Including All Activities Laid Down In All Parts In The Developed Technical Project;3. Exercising Authorial Supervision During Cmp.During The Development And Implementation Of The Project Solution, The Following Activities Should Be Foreseen:- Cutting Asphalt Pavement With A Fugorezachka;- Mechanized Excavation In Earth-Rock Soils, Incl. Landfill Removal;- Laying And Compacting Of Road Base From Crushed Stone Fraction 0-75Mm With A Thickness Of 25Cm;- Laying Of An Asphalt Layer Of Non-Dense Asphalt Concrete (Binder) With A Thickness Of 5 Cm In A Compacted State;- Laying Of An Asphalt Layer Of Dense Asphalt Concrete With A Thickness Of 4 Cm In A Compacted State;- Laying Of The First Bitumen Spill;- Laying Of A Second Bitumen Spill;- Delivery And Installation Of Road Curb 50/25/15 On A Concrete Base - Class B15 And All Related Costs. In The Section Of The Garages, Footpaths And Intersections, The Concrete Curbs Should Be Lowered;- Dismantling Road Signs- Installation Of New Standard Road Signs With Reflective Foil- Delivery And Laying Of Horizontal Marking Of White Paint With Pearls- Temporary Organization Of The Traffic, As Well As All Necessary Requirements, According To The Coordination With The Bodies Of The Road Traffic Safety Authority (Kat).Existing Situationthe Aim Of The Project Is To Restore And Improve The Transport And Operational Qualities And The Bearing Capacity Of The Pavement, With A View To Ensuring Conditions For Traffic Safety And Good Drainage Of The Streets.The Asphalt Pavement In The Considered Sections Is In A Severe Operating Condition, As A Result Of The Reconstruction Of The Internal Water Supply Network. The Remaining Asphalt Layer Is Cracked, With Many Unacceptable Deformations And Destructions. In Some Places, The Crushed Stone Base On Which The Asphalt Layers Are Laid Is Found. After The Replacement Of The Water Pipe, The Back Embankment Made Of Rock Material Has Subsided In Some Places, Making It Difficult For Pedestrians And Motor Vehicles To Move.Sidewalks In Populated Areas Will Not Be Built.Existing Longitudinal And Transverse Slopes Are Variable.The Organization Of Traffic On The Streets Has Deteriorated Safety Due To The Poor Condition Of The Pavements. There Is No Horizontal Marking, And The Available Vertical Signaling Needs To Be Brought Up To Standard.The Scope Of Activities Includes The Reconstruction Of Street Pavements With An Average Width Of 5 M.A Detailed Description Of All Planned Activities Is Contained In The Technical Specification Attached To The Documentation.
