Plans and Proposals

The plans specify exterior galvanized steel band connections at several existing-to-proposed RCP tie-ins and concrete collars at others. Due to concerns with achieving a reliable seal and fit using the exterior steel band on existing RCP, would NDDOT allow the Concrete Collar Detail shown in Section 20 to be used in lieu of the exterior steel band at all RCP tie-in locations?

What is NDDOT's intention regarding the shoring being installed during Phase 2 as opposed to Phase 3? Would it be considered if shoring was installed in Phase 3 when all traffic when all traffic is off the Eastbound lanes?

Are the bid items for TEMPORARY BYPASS and REMOVE TEMPORARY BYPASS for the bypasses associated with the gap paving only as there are only 2 each? Are there quantities for this work in the plan? Please clarify. Thanks

I am looking for the CAD files for project #23810 in Burleigh County.

Will the DOT allow the contractor to utilize/burn up the common excavation - waste (10541 CY) onsite within construction limits or will it need to be hauled off?

Regarding the E-ticketing SP issued with Addendum 3: What capabilities will the NDDOT require through the E-ticketing app? The new SP says, “the Engineer will notify the Contractor that all or a portion of the load was rejected.” Does the notification need to occur within the app or can the notification occur verbally, by phone, text, or email? If the NDDOT uses the contractor's Haulhub/Jobslip account, inspectors would lose access to eDOT’s functionality, including load rejection and other DOT functions. They could still view e-tickets for the project and daily running totals, but Jobslip currently only supports exporting of individual tickets not daily totals. Each inspector could only be assigned to one project within one contractor’s Jobslip account at a time. The contractor would need to add and assign inspectors when they arrive, then remove them before another contractor could add them to its account. This process would repeat each time an inspector moves between contractors. The engineer/inspector couldn't be on more than one contractor's Jobslip account or have access to more than one project. Do the tickets need to be stored in the cloud/app or can “one time” tickets be issued? For instance, are emailed tickets acceptable if the information is in a digital format? Does the app need to tabulate the quantities or simply make the quantities available?

In Section 6 Sheet 6 Note 704-PO5 masking using removable tape is called out, but in the last part it says "if used". Will greying out with paint be acceptable or is using removable tape be the only acceptable method?

302-P01 calls for the base course to be tightly bound, show no rutting, and no displacement under the roller after trimming. If the baskets are not placed 2000’ ahead of the paving operation and two trimmers are used, does this note apply to both trimmers?

What type, size, and spacing of reinforcement is in the existing 7" continuously reinforced concrete?

SP 593(25) states the “Salvaged base course shown in the plans needs to follow the requirements outlined in Section 302..." [i.e. Uniformly mix aggregate placed in windrows before spreading. Compact aggregate, utilizing pneumatic-tired rollers, until the surface is tightly bound, shows no rutting, and no displacement occurs under the roller operation.] And “In addition to the requirements outlined in Section 302…provide salvaged base course that meets the requirements outlined in Table 302-01…" And “Salvaged base course must meet both the elastic modulus and moisture content requirements at the time of base course placement. In addition, the salvaged base course must meet the elastic modulus requirement after salvaged base course has been trimmed for the first time and within 72 hours of concrete placement.” Note 302-01 states “Once the trimming operation is completed, ensure the base course is tightly bound, shows no rutting, and no displacement under roller operation”. What will be done to ensure ALL the SBC meets the requirements of Section 302 and the specified elastic modulus and moisture content AT THE TIME OF PLACEMENT (prior to trimming) and not just the SBC at the location of the LWD test?

Note 550-P01 waives the requirement to place steel, tie bars, and dowel bar assemblies 2,000 feet ahead of the paving operation and allows the use of the roadway as a haul road provided temporary construction access crossovers and interchanges are utilized to limit the amount of hauling over the finished base course. What is the maximum spacing required for the crossovers? Is there a minimum spacing that will be allowed?

Note 302-P02 allows the shoulder to be used as a haul road and prohibits aggregate trucks, dump trucks, etc. from driving on the roadway base course within the proposed concrete pavement width except when dumping. Note 550-P02 allows the shoulder to be used as a haul road and prohibits driving on the base course within the proposed concrete pavement width except when dumping. Note 550-P01 waives the requirement to place steel, tie bars, and dowel bar assemblies 2,000 feet ahead of the paving operation and allows the use of the roadway as a haul road. If the roadway is used as a haul road, will trucks be required to stay on the shoulder except when dumping?

Will the NDDOT provide or pay for the secondary control for stringless paving?
