| Question: Would NDOT please consider changing bid item 20 - Soil Cell System to an "Each" quantity in lieu of a Lump Sum. There appears to be a substantial quantity and Lump Sum quantity is fairly difficult to take off and/or Track. Also, Bid Item 19 - Trenching is for the Landscaping - 11,490 Square Yards? This appears to be an error. Bid Item 29 Tree Grates, Is there a particular Manufacturer for the Tree Grates? |
| Answer: Bid item 203 0770 - Soil Cell System will remain a Lump Sum item. For bid item 203 0620 - Trenching, the correct quantity is 1,395 SQYD. A supplemental will be issued showing the correct quantity for trenching. There are 3 specific manufacturers to be used for the tree grates, these manufacturers will be included in the special provisions with a supplemental. There will be a forthcoming supplemental for the plan sheets and special provisions. |

| 22 | 2 | Additional 609 and 650 Specifications | 08/08/2024 08:07 AM | Q&D Construction | Response Published |
|
| Question: There are additional specifications at the end of the special provisions. What authority do those have? For example in the back end section under that section of 609.04.08 and 650.04.08. it states that the Contractor shall provide all soil compaction testing required as specified in Section 336.03 of the Standard Specifications. NDOT typically always performs compaction testing, can you please confirm who will be responsible for the compaction testing. |
| Answer: The additional specifications attached to the Special Provisions will apply to this project. Compaction testing will be the responsibility of the Department. A supplemental will be issued to remove the contractor compaction testing requirements as this will be performed by the Department. This will be addressed in a forthcoming supplemental. |

|
| Question: NDOT has called out a reference "water tight" on RCB's. We are not sure what the specific reasoning is for the reference of water tight or if it is applicable. |
| Answer: The intent is to prevent joint leakage when in proximity to water utilities. A supplemental will be provided that provides additional guidance. The change states: “ALL PROPOSED RCP'S WITHIN 10' OF KNOWN EXISTING OR PROPOSED WATER LINES ARE TO HAVE WATER TIGHT JOINTS. ALL PROPOSED RCB JOINTS WITHIN 10' OF KNOWN ACTIVE EXISTING OR PROPOSED WATER LINES ARE TO BE INSTALLED TO PREVENT JOINT LEAKAGE AND PROVIDE POSITIVE JOINT SEALS CONSISTING OF: A WATER TIGHT GASKETED JOINT PER SUBSECTIONS 502.03.24 AND 707.03.02 OR JOINTS PROPERLY HOMED AND SEALED PER SUBSECTIONS 502.03.24 AND 707.03.02 AND EACH INTERIOR JOINT GAP SHALL BE FULLY GROUTED ALONG THE SIDES AND INVERT REGARDLESS OF GAP DIMENSION OR JOINTS PROPERLY SEALED PER SUBSECTIONS 502.03.24 AND 707.03.02 AND EACH EXTERIOR JOINT SHALL HAVE AN EXTERNAL SEALING BAND PER ASTM C877 WITH A MINIMUM WIDTH OF 9 INCHES.” This will be addressed in a forthcoming supplemental. |

| 111 | 11 | Winter maintenace and Temporary drainage systems | 08/19/2024 01:19 PM | Q&D Construction | Response Published |
|
| Question: It looks like there could be a substantial amount of Temporary patching required that could be left in place through out the winter. What are the expectations for temporary asphalt patching? In addition to this, once the new storm drain box is tied in, the existing drainage is essentially cut off. With the curb and gutter alignment and elevations changing, this could leave Drop inlets either substantially higher or lower than the existing grades(unable to tell). This could have significant impact to winter drainage and even a summer thunderstorm. What is expected of the contractor for these events as handling temporary drainage with a "Type 3 & Type 11" Drop inlets are not feasible. |
| Answer: Please refer to the Summary of Base Surface Quantities in the plan sheets. Plantmix for utility patching shall meet the requirements of the Special Provisions and Standard Specifications and have been quantified for use. Temporary patching is to be placed in a manner that will facilitate the Departments maintenance activities during suspension periods. Temporary drainage needs are determinant on means and methods used by the Contractor. Per Section 108.04 of the Standard Specifications, "Sequence construction activities to perpetuate historic flow patterns and conveyances for both temporary and permanent flow. Temporary conveyance is at the expense of the Contractor and shall be safely conveyed to a reasonable and safe outfall location." Additionally, refer to paragraph two of Section 108.06 of the Standard Specifications. |

| 115 | 15 | City Section 609.04.03 - Trench Construction | 08/21/2024 06:14 AM | Q&D Construction | Response Published |
|
| Question: Per this section: "Excavated Material - All excavated material shall be directly loaded into dump trucks or other means of transportation as it is being excavated, and hauled off of site and dumped at the approved designated disposal area. No excavation material shall be stockpiled or placed on the roadway, other surface areas of the project site, areas and locations adjacent to the project site, or at the laydown area(s) at any time." Does the City have and approved disposal Area for the project, that they are providing? Above they state we are not allowed to use a staging yard? Furthermore, it states "The Contractor shall broom clean-up the entire project site on a continuous basis during the entire construction of the project, and once all work is complete." In addition the City Specifications and NDOT's Spec numbers are doubled up, Can these sections of specifications be cleaned up. For example section 609.04.01 section one is referencing "Measurement" and the other is "PVC Pipe Joint Assembly". |
| Answer: For excavated material, refer to Section 106 of the Special Provisions. Contractors may coordinate with the City Engineer and Landfill Operator for additional locations to dispose of excavated material. City Water and Sewer Utility work performed outside of NDOT Right of Way requires continuous clean-up of project during construction. The Special Provisions will be renumbered for Sections 609 and 650. A supplemental will be issued for the updated Special Provisions. |
