Tenders Are Invited For Reconstruction Of District Road No. 1956C Chomętowo - Łabiszyn Along With The Construction Of A Bicycle Road On The Smerzyn - Łabiszyn Section

The Subject Of The Order Are Construction Works Consisting In The Reconstruction Of The District Road No. 1956C Chomętowo - Łabiszyn On The Smerzyn - Łabiszyn Section, Including: • Construction Of A Bicycle Road; • Reconstruction Of The Road Surface Of The District Road No. 1956C Consisting Of Milling, Making A Leveling And Wearing Course; • Reconstruction Of The Culvert; • Reconstruction Of Roadside Works; • Hardening Of The Roadsides; • Assembly Traffic Safety Elements;• Introduction Of A New Traffic Organization (Vertical And Horizontal Markings). The Works Should Be Performed In Accordance With The Design Documentation, Zrid Decision, Construction Notification, Applicable Legal Regulations, Technical Standards And Principles Of Technical Knowledge. Design Status: A Two-Way Bicycle Path Has Been Designed, With A Road Width Of 2.50 M, With A Bituminous Surface. On Sections Running Directly At The Edge Of The Road Of The District Road, The Width Of The Bicycle Path Was Assumed To Be 3.00 M, Which Results From The Need To Maintain The Required Road And Bicycle Road Gauges. The Bicycle Path, Located At A Distance Of At Least 1.0 M From The Road Of The District Road, Is Framed With A Concrete Pavement Edge Measuring 8 × 30 Cm, Placed On A Concrete Bench With Resistance, Made Of C12/15 Concrete. On The Section Of Integration Into The Internal Road In Smerzyn, At Km 6+292 - 6+310 (Right Side), And On The Section Of Inclusion And Exclusion Of Bicycle Traffic At Km 9+422 - 9+432, The Bicycle Path Is Separated From The Road By A Lightweight Concrete Curb With Dimensions Of 15 × 30 Cm, Protruding 12 Cm Above The Road Level. At Bicycle Crossings, Ramp Curbs Measuring 15 × 22 Cm Are Used, Protruding A Maximum Of 1 Cm Above The Road Surface. All Curbs, Stops And Edges Are Designed To Be Placed On A Concrete Footing With Stops, Made Of C12/15 Class Concrete. The Project Assumes That The Bicycle Path Will Be Limited On The Side Of The Road With A Concrete Pavement Edge Measuring 8 × 30 Cm. Behind The Bicycle Path, A 0.50 M Wide Dirt Shoulder Was Designed, With A 6% Transverse Slope Towards The Ditch. Next, It Is Planned To Construct Trapezoidal Roadside Ditches. Construction Of The Bicycle Road Surface: • Leveled Earth Bed, • 10 Cm Thick Sand Cut-Off Layer, • Subbase Made Of Unbound C90/3 Mixture (Mechanically Stabilized Crushed Aggregate 0/31.5 Mm) 20 Cm Thick, • Ac11s Asphalt Concrete Wearing Course, 6 Mm Thick Cm. Construction Of The Exit Surface: • Leveled Earthen Bed, • 10 Cm Thick Sand Cutting Layer, • Subbase Made Of Unbound C90/3 Mixture (Mechanically Stabilized Broken Aggregate 0/31.5 Mm) 20 Cm Thick, • Binding Layer Of Ac16w Asphalt Concrete, 4 Cm Thick, • Asphalt Concrete Wearing Course Ac11s, 6 Cm Thick. Road Structure, District Roads J (Reconstruction Of The Surface After The Reconstruction Of The Culvert), • Leveled Earth Bed (Backfilling Of The Culvert), • Cut-Off Layer Of Sand, 10 Cm Thick, • Sub-Base Made Of Unbound Mixture C90/3 (Mechanicall
