Bids received after the specified deadline will not be considered and will be returned unopened. Bids must be made in good faith and without collusion. In the event that a bidder suspects or determines the proposal is incomplete, notify Chris Kaufman, Public Works Director at (802) 649-2209. The road closure for the project shall be for a maximum of 30 days between June 15th (after school year ends) and August 26, 2026 (before school year starts) with the project completion of the project by October 1st, 2026. ENGINEERS ESTIMATE: For this Proposal the Engineers Estimate is $190,000. Addendum: Response to questions will be sent in an Addendum by email to all contractors by 4:00pm on 3/10/2026. QUESTIONS: During the advertisement phase of this project all questions shall be submitted in writing by 4:00pm on 3/9/2026 and addressed to: Everett Hammond, Engineer (802) 376-0042 hammondeng@gmail.com Common Excavation (Modified VTRANS to Lump Sum): The pay for this line item has been modified from Cubic Yards (CY) to Lump Sum (LS). This is for the excavation of the inlet material as shown by the proposed contours shifting the drainage path from the existing 24" CMP to the proposed 5' diameter pipe. Structure Excavation (Modified VTRANS to Lump Sum): The pay for this line item has also been modified from Cubic Yards (CY) to Lump Sum (LS). This is for the excavation for the 5' diameter pipe and the existing cast in place box/24" CMP. The estimated volume is as follows: o 17' length (over culverts) x 40' width x 13' depth/27 = 327 CY o 20' length (slopes) x 40' width x 13' depth/27 = 385 o Cutoff walls: 20' length x 3' width x 4' depth x 2 each = 480 CF/27 = 18 CY Total estimated excavation = 327 CY +385 CY + 18 CY = 730 CY. Granular Backfill for Structures (Modified VTRANS limits): The pay for this line item has also been modified from Cubic Yards (CY) to Lump Sum (LS). Granular backfill and compaction to 95% modified proctor. Granular backfill (VTRANS Specification 704.08A) shall be installed on the outside of the pipe (above the concrete pipe haunch to the road subgrade. This is for the granular backfill from 2.5' each side of the new 5' pipe to subgrade elevation (2'- 10" below the top of pavement). Calculations are as follows: 10' wide x 49' along pipe x 3' above the concrete = 1,470 CF/27 = 54 CY Less 2/3 pipe volume: 2/3 x 3.14 x 2.5 x 2.5 x 49' = 640 CF/27 = -24 CY 10' wide x 40' along pipe (less outer slope areas) x 5' above the top of pipe (avg.) to subgrade = 2,000 CF/27 =74 CY TOTAL: 54 CY - 24 CY + 74 CY = 104 CY compacted in place; 130 CY estimated truck measurement. Material purchased by the ton shall be at a factor of 1.9 tons/CY. 104 CY x 1.9 = 198 TON (USE 200 TON). 5' Dia. x 49' Aluminized Steel Pipe (10 gauge, single length pipe): This work will include all work associated with the installation of the new Aluminized Steel Pipe and wingwalls The installation of the precast box culvert shall include the following: o Excavation for the pipe, and cut off walls (included in 204.2500 - see above). o This shall be for the placement of the preformed cutoff walls for the outlet wingwalls. o 5' diameter x 49', Aluminized Steel Pipe, 10 gauge minimum thickness, designed to HL-93 loading with 1.75' to 4' of cover. Prefabricated 10 gauge aluminized steel outlet wingwalls/headwall as shown on plan sheet 4. Pipe shall be a single length pipe (no joints)with pre-fabricated headwall/wingwalls on the inlet and outlet end as manufactured by Contech (or equal). o Excavator or crane for placement of the pipe and outlet wingwalls/headwall. o Setting of the pipe, cutoff walls, outlet wingwalls/headwall. o Installation of tie backs for the outlet wingwalls/headwall. o Bedding: 4" of Fine Dense Grade (or equal) capped with 2" +/- of course surepak (or equal) fine graded to within 1" or less along pipe profile. o Installation of VT Class 2 Concrete 4" under the 5' diameter pipe and 1.5' up the sides of the pipe sloping away at a 1:1 slope. See detail on sheet 5/7. The concrete shall average 11 CF/foot of pipe x 49'/27 = 20 CY. *The list of planholders and/or interested bidders is not being tracked by the stakeholders involved with this project.
