Tenders Are Invited For Reconstruction Of Fire Roads No. 90 And 132 In The Brzozówki Forest District - Proce ... in Poland

Work Detail

The Subject Of This Order Is The Reconstruction Of A Forest Road In The Brzozówki Forestry. Reconstruction Of Roads No. 90 And 132 In The Brzozówki Forest, Km 0+000 To Km 5+100.60A) General Assumptions: The Road Structure Was Designed To Be Made Of Crushed Aggregate, 3.50 M Wide On Straight Sections, And 3.00 M Wide And 23.00 M Long Passing Roads With An Analogous Structure To The Road. The Road Will Have 0.75 M Wide Dirt Shoulders And Evaporation Ditches. In Order To Better Manage Rainwater, Culverts Under The Road Will Be Renovated. Basic Parameters Of The Designed Road: - Design Speed 30 Km/H - Internal Access Road Category For The Needs Of The Forest Complex - Traffic Category - Kr1 Length Of The Designed Section - 5,100.60 M Width Of The Road On A Straight Section - 3.50 M Width Of The Road With Widening On The Curves 3.50M-6.50M Width Of Roadsides - 0.75M Width Of Passing Places - 3.00M Length Of Passing Places - 23.00M The Road Geometry With Minor Corrections Was Adapted To The Existing Condition. The Cross-Section Of The Road On Straight Sections Is Designed As A Roof With A Cross-Section Of 3%. B) Road Construction: The Project Assumes A Single-Lane Road. Along The Entire Length Of The Road, The Lower Layer Of Crushed Aggregate 0/63, 20 Cm Thick, And The Upper Layer Of Crushed Aggregate 0/31.5, 10 Cm Thick, Should Be Made. In Places With Insufficient Load-Bearing Capacity, I.E. At Km 0+250 To Km 0+880 And Km 2+350 To Km 2+650, An Additional Structural Geotextile Should Be Used Directly Under The Lower Layer Of Crushed Aggregate On A Leveled Surface. A 3% Roof Slope Should Be Used Along The Entire Length Of The Road, Except For The Section Of The Year-Round Zone (Km 2+351.00 To Km 2+555.00) Where A 3% One-Sided Slope Should Be Used. Road Widenings On Curves Should Be Made In Accordance With The Attached Drawing Documentation. Road Width On Straight Sections - 3.50 M, On Curves - 3.50 M + Widening Depending On The Radius. The Road Grade Should Take Into Account The Existing Topography And Exits To The Forest Complex. The Road Surface Of The Road And Widenings Should Be Graded With Aggregate Of 2-8 Mm Thickness. Approximately 0.5 Cm To 1.5 Cm. C) Exits: In Order To Connect The Road With The Adjacent Area, Exits To Roads Of Other Properties Are Designed. Rounding Radii Of Exits Are Min. 11 M. The Road Surface On Exits Should Be The Same Width As On The Road, Along The Length Given For The Road Situation. D) Passing Circles: In Order For Vehicles To Safely Pass Each Other On The Road, Passing Lanes Have Been Designed. The Width Of A Typical Passing Lane Is 3.0 M, The Length Is 23 M, The Entry And Exit Slopes Are 1/7. The Transverse Inclination Of The Passing Area Should Be The Same As The Road On This Section. The Location Of The Passing Areas Is Shown On The Site Plan. E) Roadsides: As Part Of The Investment, Dirt Roadsides With A Width Of 0.75 Are Being Designed On Both Sides. The Shoulders Should Be Constructed With A 6% Slope Towards The
