The quantity for the barrier wall was corrected to cubic meters and the total for minor concrete was corrected to cubic meters. P a g e 1

2 Request for Proposal (RFP) Bid No: VJ Addendum No. 2 Please see the revised plan sheets 6 & 28 and the revised bid schedule. What is solid yellow labeled under the Thickness column of the table? The words "Solid Yellow" is an error and should state "varies" on this table. Please see the revised plan sheet 28. Can you please send me a copy of the sign in sheet from last week? Can I get a copy of the plan holders list, if available? Do contractors and subcontractors need to have an Arizona Contractors license, or would another state work? Please refer to Addendum No. 1 for the pre-proposal meeting sign-in sheet. There is no plan holders list. The contractor and subcontractors need to be duly registered and have a valid license in the state of Arizona for the type of work to be performed under this contract. Please refer to Article 12 Licensing & Registration Requirements of Exhibit B Navajo Nation Supplemental General Conditions. How is rock excavation going to be addressed on the project, will a change order be issued or are you going to add a line item to the RFP? Is rock excavation going to classified as Rock that is blasted or the use of rock hammer or dozer ripper? Please refer to Addendum No. 1. There is no separate line item for rock excavation. There is a geotechnical report available for the project for Contractor s information. Payment for rock excavation is included in bid item Roadway Excavation. Has NDOT considered extending the proposal deadline beyond August 23 rd? NDOT will not be extending the proposal deadline. P a g e 2

3 Request for Proposal (RFP) Bid No: VJ Addendum No. 2 Is it the intent to capture all the components required of Section 153 (Quality Control Manager, Technicians/Inspectors and laboratory & field-testing asphalt mix designs, per diem, etc.) necessary for this project in this item? If so, this will result in an extremely high hourly rate. The specifications also contain Section 154 Contractor Sampling and Testing. I believe the bid schedule should reflect a bid item for work required by Section 154 and both items should be under a lump sum unit. This is how the FHWA bid schedule is set up. Page 88 states that the QCM cannot be an employee of the Contractor s lab. If a Contractor retains an AASHTO accredited consultant to provide Item 153 Contractor Quality Control why would that preclude the QCM from being from the same firm? Page 87 Section (1) Quality Control Manager states The Government shall designate a qualified Quality Control Manager (QCM) who will be paid for by the Government directly. This conflicts with the rest of the specification that explains the necessary qualifications as well as designating a Please refer to Article 10 Furnishing of Contractor Field Testing Laboratory of Exhibit C Special Contract Requirements for discussion regarding the cost of Contractor Field Testing Laboratory. The laboratory, utilities (including all associated monthly costs), accessories, and all equipment required by the contract requirements including furnishing of a laboratory site shall be included in the unit price bid for mobilization No additional bid items will be established. Please refer to Section (d)(1) of the Exhibit F Supplemental Specifications. "The Government shall designate a qualified Quality Control Manager (QCM) who will be paid for by the government directly and will be an agent for the government on this contract. The Government will designate and retain the QCM on this project. The QCM will be paid for directly by the Government. The QCM cannot be an employee of the same company that provides the QC materials testing for the Contractor. The Government will retain the QCM. See previous question response. If a stand-in QCM is needed, the Government will designate the stand-in and notify the Contractor. This individual will not be an employee of the Contractor or the Contractor s materials testing firm. P a g e 3

4 Request for Proposal (RFP) Bid No: VJ Addendum No. 2 stand-in QCM to act on behalf and serve only in the absence of the QCM. Please clarify who will retain the QCM. Page 4 states that The Contractor shall not use the Materials Lab hired under this contract for the sampling and test.would you please identify the firm that is retained by the Government? The Materials Lab referred to in Article 6 Borrow and Aggregate Materials of Exhibit C - Special Contract Requirements is in regards to the Contractor s borrow/aggregate pit testing. The Government will not pay for testing of these items. A QA firm has not been identified at this time. The Government will select an independent materials lab to complete QA assurance testing after the successful Contractor has been awarded the project. This allows all current material/testing labs the opportunity to place a bid with contractors for the Quality Control materials testing work. Page 86 of Section 153(e) states The Contractor shall promptly furnish, at no increase in contract price, all facilities, labor, and materials reasonably needed for performing such safe and convenient inspections and tests as may be required by the CO. Is it the intent of NNDOT to have the Contractor provide an on-site lab for the Government? What is the estimated construction cost? The Government requires that the Contractor provide an on-site Field Testing Laboratory to complete the Contractor s Quality Control Plan. A separate lab for Government use is not required. NDOT will not be providing the engineers estimate of construction cost, but does have a budget and available funding. P a g e 4

5 Request for Proposal (RFP) Bid No: VJ Addendum No. 2 Per sheet 94 of 96, note 4 states contractor is responsible for determining all bar length dimensions for barrels, wingwall and concrete apron.. We cannot estimate the rebar quantity using the table shown on sheet 94. Can the contractor use the rebar design for the wingwalls and concrete apron as shown on sheets 45 & 46 of 96? Or can we use ADOT standards to estimate the reinforcement? Please provide your guidance on how to estimate the rebar for bid item On sheet 90 of 96 (End Elevation view), there is a 76 mm diameter weep hole. Does the weep hole run along both sides of the box culvert wall? Or does it go through the wingwalls only? Or both? The weep holes are only for bid item ? Or do we need to construct it for the CIP box culverts even though there is no detail shown on sheets 44 thru 46 of 96. What is the length of the outlet pad as shown on sheet 74 of 96? Is there a sheet for the splitter island that shows the layout details? Perimeter and area? What does the area include for the splitter islands shown on the table for the Minor Concrete? Does it include both the curb and gutter and interior (dome slab pattern)? Please confirm. The Contractor may use sheets 45 & 46 to estimate their reinforcement for bidding purposes, but the final design is the Contractor s responsibility as called out in Note 4. The weep hole is noted as being continuous and should run the entire length of the box culvert on both sides. The weephole is required for the CIP option as well. The length of the outlet pad should be 2.4 meters. Please refer to sheets 25 & 27 for splitter island layout details. The areas in question are listed on the minor concrete table on sheet 28. The areas listed are for the dome slab pattern only and do not include the curb and gutter. P a g e 5
