Continued In Additional Information (Bt-728-Procedure). The Subject Of This Public Procurement Is Selection Of A Contractor For The Preparation Of A Complex Report For The Assessment Of Compliance With The Main Requirements For Construction And Technical Control Under The Constructive Part And The Exercise Of Construction Supervision For The Update And Addition Of A Technical Project For Carrying Out Repair And Restoration Works, With The Aim Of Bringing The Trajanovi Vrata Tunnel On The Trakia Am, At Km 53+297, Which Coincides With The Trans-European Road Network (Tent-T) The Purpose Of The Public Procurement Is For The Road Infrastructure Agency To Identify A Contractor And Enter Into A Contract With Him For The Preparation Of A Complex Report For Assessing Compliance With The Main Construction Requirements And Technical Control Under The Constructive Part And Exercising Construction Supervision During The Construction Of The Same, With A View To Carrying Out Quality Construction Of The Site In Accordance With The Regulatory Requirements And Compliance With The Agreed Deadlines. Existing Situation: Tunnel Trajanovi Vrata Of Am Trakia At Km 53+297 Was Put Into Operation In 1985 And Has The Following Technical Characteristics: Length Of Left Pipe - 685 M; Length Of The Right Pipe – 720 M; Number Of Active Strips - 3 Pcs. From 21.02.2025 A Technical Expertise Has Been Prepared For The Tunnel, Which Indicates The Main Problems That Reduce The Serviceability Of The Facility And Create Risks For Passing Motor Vehicles, As A Result Of The Poor Condition Of The Waterproofing And The Implementation Of Previous Repair Activities. Found Defects And Damage: The Designation Of The Tunnel Pipes Was Adopted According To The Increase In Mileage: Right Pipe → Direction Sofia - Plovdiv Left Pipe → Direction Plovdiv - Sofia In Both Pipes, During The Last Repair, In The Lower Part Of The Pyedrites, Ready-Made Reinforced Concrete Elements With A Height Of 240 Cm Were Inserted, From Which Sprayed Concrete Was Filled Upwards Along The Entire Arch Part. Left Pipe: Along The Entire Length Of The Pipe, In About 24M, Transverse Cracks Have Formed, Covering The Entire Vault, And Sometimes Going Down To The Sidewalks. There Are Unstable Pieces Of Concrete In Places Near The Cracks. During The Three Control Measurements Of The Distance From The Base Of One To The Base Of The Other Piedrite (Ie Between The Outer Edges Of The Pavements), The Following Results Were Obtained: - 12,440 Mm; - 12,048 Mm; - 12,217 Mm. The Difference Of Nearly 40 Cm, Possibly Resulting From Previous Repair Works, Is Serious And Warrants A More Cautious Approach Regarding The Tunnel Gauge. The Light Fixture Cables Are Hooked Right Into The Trim And This Makes Them Vulnerable. In The Three Control Measurements, A Maximum Difference In The Width Of The Sidewalks Of Nearly 15 Cm Was Recorded (The Minimum Width Is 57 Cm). In The Lining, At The Height Of One Tir, There Are Scratches, Which Testify To The Insufficient Gauge Of The Facility. Right Pipe: There Are Cracks On The Right Wing On The Sofia Side. There Is A Longitudinal Crack In The Key From The 20Th To
