The driving cost for this project are the piles, access, and TOY/Lane Closure Restrictions. These are not typical DBE items. Where did the Department envision 11% DBE participation on this project? Please reconsider the DBE goal for the project.

The typical sections show 4’ shoulders at locations with St’d GR-MGS1 (guardrail) and/or GR-MGS2 (guardrail terminals) per the Road and Bridge Standards. The typical sections only show 3’ shoulders at locations with St’d. GR-FOA-1 fixed object attachments which are based on GR-2 standards per the Road and Bridge Standard. The typical sections only show 3’-4’shoulders at locations with St’d. GR-MGS4 transitions as per the Road and Bridge Standards. Long post guardrail is not required for the GR-MGS4 transition per the detail which transitions the shoulder from 3’ wide to 4’ wide.

The Special Provision for Limitation of Operations prevents bridge demolition or construction from October 1-December 31 of any given year. The Time of Year Restriction in the permits prevents in-stream work between February 15-June 30 of any given year. For the bridge over the main channel, this means that the existing bridge must be demolished, 6 cofferdams must be installed, test piles must be driven, production piles must be approved, fabricated, and installed, and 6 cofferdams must be removed between January 1 and February 14 (6 weeks). If not, the balance of this work, plus bent cap construction, superstructure construction, and approach roadway tie-ins must be completed between July 1 and September 30 (3 months). Superstructure work cannot begin until all in-stream work is completed. 6 weeks is an inadequate amount of time to perform all of the in-stream work on this project. Please consider eliminating the Special Provision for Limitations of Operations for this project. If cofferdam installation/removal will not be considered in-stream work, please clarify.

Time of year applies to B666 Nottoway river only. Instream work prohibition applies to work below the surface of the water outside of the water tight cofferdams, which would include hollow piles for any temporary work trestles. It does not include those bridge elements above the surface of the water. Once cofferdam cells are installed and deemed water tight, the time of year prohibition no longer applies to any work within the cells.

The restrains between the roadway closure and the TOY closure make this job impossible to construct. One way to alleviate this would be to make the cofferdams sacrificial and cut them off below the mud line. This would allow super structure construction to commence, and they sheets could be cut off after the TOY restriction ends. This would result in substantial extra cost, to leave the sheet pile in place, and would require divers for the cut off work. Would the department allow this?

Time of year prohibition for instream work is a permit condition and cannot be eliminated without re-coordination with the regulatory agencies and their approval to modify the existing permits.
Removal of instream cofferdam sheets is subject to the time of year prohibition. Removal of temporary cofferdams during the 2-15 to 6-30 prohibition would require re-coordination with the regulatory agencies and their approval to modify the existing permits.
Cutting off the cofferdam below the mud line is acceptable from a constructability standpoint, however, cutting off the cofferdam must comply with the Time Of Year restrictions, or obtain a permit modification.

In regard to the question asked above, can the time of year restriction be removed from February 15 to June 30? The schedule will be near impossible to complete all work in the given time frame for B666 between the NTP, time of year restriction, and the mandate to reopen the road to traffic on 9-30. If the restriction is not removed, will the contractor be allowed to remove the temporary cofferdams prior to 6-30 or does the removal fall under the time of year restriction as well?

The expectation then is that the contractor "only" has to demolish the superstructure and install 6EA separate cofferdams between 1/1 and 2/14. Work within the cofferdams will take place during the TOY restriction. From 7/1-9/30, the contractor must remove all cofferdams, erect beams, pour the bridge decks/closure diaphragms/rails/approach slabs, and tie-in the roadway. Would bubble curtains, or other mitigation measures be allowed so that sheet piles can be installed and/or removed during the TOY restriction?

The use of bubble curtains, or other mitigation measures would require a formal request to the governing agencies, who will need design details for the proposed measure.

Based on the Top of Pile elevation "G" and Minimum Pile Tip elevation "P" shown on plan sheet 8 of 33 on both bridge 292-79 and 2912-80, the total pile length = 1,176 LF. Bid Item 0930 Pile Precast Cylinder Pile shows 1,128 LF.

Each pier has 4 piles - 3 production piles and 1 test pile. The 36” Precast Cylinder Pile bid item is for the 3 production piles and uses the Estimated Pile Tip Elevations from Sheet 2 of each plan set to calculate the length of the piles. The Pile Driving Test for 36” Precast Cylinder Pile item is for the test pile and also uses the Estimated Pile Tip Elevations from the table on sheet 2. The quantity of 1,128 LF is correct.
