HOWEVER, IT IS THE STATE?S MANDATE, AND THAT OF THEIR CONTRACTOR TO REFRAIN FROM THE IMPEDANCE OF BNSF?S RAILWAY OPERATIONS. THEREFORE CAREFULL COOPERATION BETWEEN THE CONTRACTOR AND BNSF WILL BE REQUIRED.

Response posted 01/12/2018




Inquiry #24: For traffic breaks, the minimum amount of COZEEP hours that the Contractor is responsible for is dependent on whether or not a closure is in place during the requested traffic break. Section 12-4.02D states that if a closure is in place then the minimum number of hours for an officer is 1 hour. This seems to imply that COZEEP support will be on-site during all closures.

Inquiry #27: Section 71-6.03D in the Special Provisions states that the inside culvert backfill is both 1) included in bid item #193 Abandon Culvert and 2) paid for in bid item #199 Sand Backfill. Please confirm that the inside culvert backfill will be paid for in the bid item for Sand Backfill.
Inquiry submitted 01/15/2018

Response #1: Basically, if you only count the individual drainage system, it might fall into the pay item of ?Abandon Culvert? and without a separate pay item of ?Sand Backfill?. However, when we consider the whole project, the five cubic yard criteria is applied for total amount of every drainage systems. Since this project has the total amount more than five cubic yard, so ?Yes?, the inside culvert backfill total amount will be paid in ?Sand Backfill?.

Inquiry #31: The Type Softstop terminal system is the only in-line terminal system end treatment specified in the contract documents.

We do not agree with this. Caltrans Standard Specifications 2015, Section 6-1.05 Specific Brand or Trade Name and Substitution states "reference to a specific brand or trade name establishes a quality standard and is not intended to limit competition. You may use a product that is equal to or better than the specified trade name if authorized".

Further, FHWA Title 23 CFR 635.411 states Federal Funds shall not participate, directly or indirectly, in payment for any premium or royalty on any patented or proprietary material, specification, or process.

The MSKT is a Caltrans approved in-line terminal and we believe it should be allowed for use on this project.

Please review and clarify why Caltrans will only allow the proprietary Softstop on this federally funded project.

Inquiry #32: Special Provisions section 7-1.02K(6)(j)(iii) states that the average lead concentrations are below 1,000 mg/kg total lead and below 5 mg/L soluable. Therefore the material is 1) Not Hazardous Waste and 2) Does not require disposal at a permitted landfill or solid waste disposal facility....Reuse all the excavated material on the right-of-way.

Inquiry submitted 01/26/2018

Response #1:1) The material is contaminated with Lead but not hazardous. This is a SPP that covers all soil. Reuse within CT right of way of none-hazardous material is fine; however, reuse Y-1 material should be priority. 2) Y-1 material is for Re-Use on site, and when it is to be disposed, it is named as Z-2 material, hazardous waste (HW) must be disposed at the Class 1 disposal facility. 3)Please bid per plans.4) Do not miss-understand that Section 7-1.02 (6)(j) (iii).
