Resurfacing

This project is located at CO52 prospect valley within Weld County, CO. The work includes resurfacing CO52 between milepost 42 and 44 with full depth reclamation and HMA overlay. However, full depth reconstruction will be applied where maintaining existing grade is required. The project also includes one major CBC replacement at CO52 MP42.7 and one minor CBC replacement at CO79 MP20.08. PE stamped subsurface utility sheets are included in the bid plan. 201-00000 Clearing and Grubbing 1.000 L S 202-00027 Removal of Riprap 152.000 SY 202-00220 Removal of Asphalt Mat 9,427.000 SY 203-00010 Unclassified Excavation (Complete In Place) 8,904.000 CY 206-00000 Structure Excavation 1,767.000 CY 207-00700 Topsoil (Onsite) 3,227.000 CY 207-00704 Subgrade Soil Preparation 21,780.000 SY 208-00008 Erosion Log Type 2 (12 Inch) 2,900.000 LF 208-00106 Sweeping (Sediment Removal) 144.000 HOUR 213-00012 Spray-on Mulch Blanket 4.000 ACRE 304-06007 Aggregate Base Course (Class 6) 2,331.000 CY 304-08002 Aggregate Base Course (Shoulder Material) 392.000 CY 310-00608 Full Depth Reclamation of Hot Mix Asphalt Pavement (0- 8") 25,040.000 SY 310-00610 Full Depth Reclamation of Hot Mix Asphalt Pavement (8- 12") 6,186.000 SY 403-00720 Hot Mix Asphalt (Patching) (Asphalt) 100.000 TON 403-34751 Hot Mix Asphalt (Grading SX) (75) (PG 64-28) 11,453.000 TON 420-00113 Geotextile (Drainage) (Class 2) 1,335.000 SY 506-00212 Riprap (12 Inch) 718.000 CY 601-01000 Concrete Class B 2.000 CY 601-03030 Concrete Class D (Box Culvert) 43.400 CY 603-01305 30 Inch Reinforced Concrete Pipe (Complete In Place) 192.000 LF 603-05030 30 Inch Reinforced Concrete End Section 8.000 EACH 603-10180 18 Inch Corrugated Steel Pipe 41.000 LF 603-10300 30 Inch Corrugated Steel Pipe 30.000 LF 603-70604 6x4 Foot Concrete Box Culvert (Precast) 95.000 LF 603-71004 10x4 Foot Concrete Box Culvert (Precast) 156.000 LF 620-00002 Field Office (Class 2) 1.000 EACH 620-00012 Field Laboratory (Class 2) 1.000 EACH 625-00000 Construction Surveying 1.000 L S 626-00000 Mobilization 1.000 L S 627-00011 Pavement Marking Paint (Waterborne) 425.000 GAL 630-00000 Flagging 2,400.000 HOUR 630-00001 Pilot Car Operation 400.000 HOUR 630-00012 Traffic Control Management 75.000 DAY 630-80355 Portable Message Sign Panel 5.000 EACH 630-85041 Mobile Attenuator 60.000 DAY
