Specification No. 02112 2.2.A
Specification 02112 2.2.A states that "Alternative daily cover (ADC), shall be used in lieu of soil, and will consist of tarps, foam, or other material as approved by the County/Engineer. Soil shall not be used as ADC." The contractor will need to construct soil/dirt roads through the duration of the project to allow haul trucks to travel over the waste in the excavation and fill area. Will it be acceptable to use soil from the borrow source for this? (RFC 46115 submitted 2/10/2022)
Yes. However, haul road at Phase II will be limited to the areas shown in the exhibit prepared by Tetra Tech, labeled "LFGCCS Phasing Plan Stage 0" included in the Project Details section of the Specifications. With respect to Phase 1, soil from the borrow site can be used for temporary roads within Phase 1. However this soil must be reused for other stages in Phase 1 or for intermediate cover in Phase 2. Phase 1 temporary roads layout shall be coordinated with the Engineer for his/her approval prior to construction. See specification Section 01520, Paragraph 1.8. At the end of the project any soil utilized for construction of temporary roads shall be used for Phase II intermediate cover.

Response date: 03/03/2022
Has the County considered adding screening the trash to the specs? The value savings could be that it reduces the trash by up 30 percent therefore increasing the clean usable dirt for fill also adding years to the life of that area used for dumping the trash in added fill space.
(RFC 46164 submitted 2/15/2022 and RFC 46287 submitted 2/23/2022)
No, trash screening is not within the scope of this project. Response date: 03/03/2022

Does the County of Fresno have a Waste Handler Dozer the Contractor can utilize through the duration of this project? Standard earthmoving dozers are not equipped to protect against waste handling. Without a dozer waste protection system, waste can entire the radiator core, engine components, undercarriage, and final drive. Once waste enters these components, the contractor is at risk of fire hazards within the machine, major repair costs, and schedule delays. There is no rental market for waste handler dozers as these machines are specifically sold to landfills. (RFC 46212 submitted 2/17/2022)
No. Per specifications section 02112 Part 1 Paragraph 1.3, Contractor is to certify they can readily access equipment capable of performing the work. Response date: 03/03/2022

Per Details on Sheet 16 of 37, it states to remove the existing cover soil (approximately 12" to 18" in depth) and stockpile for "New Soil Cover" on top of Phase I "Waste". In Detail K/5 on sheet 29 of 37, it states to place a "2 foot thick compacted intermediate soil cover". If we remove 12" to 18" of existing cover and reuse it to cover with a minimum of 24" compacted material, where does the difference of between 6" to 12" (not including compaction) come from? (RFC 46315 submitted 2/24/2022)
Detail on Sheet 16 allows the Contractor to stockpile remaining soil on Phase II to be used for intermediate cover at Phase II. Detail K/5 on sheet 29 requires the Contractor to install a 2-foot thick intermediate cover. Contractor may use onsite borrow soil as intermediate soil cover to account for any volume differences. Reference soil stockpile areas 1 and 2 in plans, sheet 2 of 37. Reference Specifications Section 02310, Part 2, Paragraph 2.4. Response date: 03/03/2022
Specification No. 02112 (Part 2, 2.2 Daily Cover, B.)

No. Refer to Addendum #1 Section 02112 Part 2, Paragraph 2.2 Daily Cover: "Alternative daily cover (ADC), shall be used in lieu of soil, and will consist of tarps, foam, or other material as approved by the County/Engineer.
Soil shall not be used as ADC."

Why has the County chosen to eliminate all locally owned companies from bidding calling out requirements that no one locally has? I don't care if I get the job but I would like my tax dollars to stand a chance. I have the equipment, insurance and bonding. This is an easy job compared to most. Please explain. (RFC 46320 submitted 2/21/2022)
All contractors that meet the qualifications as outlined in the specifications are encouraged to bid. The qualifications as outlined, were specified based on the nature of the work: excavating, hauling, placing and compacting waste material specifically. The nature of handling waste material is different from handling soil, and requires specific equipment. The allotted Project days were derived from professionals in the field of solid waste to help ensure successful completion of the Project in the most efficient execution possible, minimizing costs to the owner while satisfying the regulatory agencies with purview of the American Avenue Disposal Site. Response date: 03/03/2022
Drawing No. 11298, Sheet 29 of 37

No. Phase 1 soil and waste shall be treated as waste and placed in Phase II and shall not be used as intermediate soil cover in Phase I. Response date: 03/03/2022
Specification No. 01290, 1.8 Pay Items, 6 Clearing & Grubbing B. Per Section 1290, 6. Clearing & Grubbing B. it states to "... treat remaining roots in soil with a weed killer, approved by the Engineer." Will this be required? (RFC 46398 submitted 3/2/2022)
No. Response date: 03/07/2022
Can the 90% compaction requirement for the wedge buttress fill be removed? This material is being compacted on top of trash and a 90% compaction will be difficult to achieve in most areas. Can the compaction specification be revised to utilize 3 passes of a D9 dozer over a 12" lift? (RFC 46408 submitted 3/2/2022)
No, this requirement cannot be removed. However, per Table 02310-3, Note 2, "If, in the opinion of the CQA Officer, soil being placed as part of the Soil Wedge Buttress Fill cannot be compacted to the requirements presented in this table due to the yielding nature of the underlying waste, the Wedge Fill Soil Buttress soils may be compacted to a firm and unyielding condition as established by the CQA Monitor or Officer." Response date: 03/07/2022
Can the County add a fuel adjustment clause to the specifications? (RFC 46409 and 46421 submitted 3/2/2022)
No fuel adjustment clause will be added to the Specifications. However, there is payment adjustments for price index fluctuations that applies to asphalt contained in materials for pavement structures and pavement surface treatments such as HMA, tack coat, asphaltic emulsions, bituminous seals, asphalt binders, and modified asphalt binders placed in the work. See Payment Adjustments for Price Index Fluctuations. Section 9-1.07. Response date: 03/07/2022
Specification No. Seed Mix Table in 02950-1
The table 02950-1 doesn’t include rate for hydroseed… are we to assume seed broadcast rate will apply? Generally drill seed rates are much less than hydroseed rates. (RFC 46410 submitted 3/2/2022)
Table 02950-1 includes Drill Seeding and Broadcast Seeding PLS application rates. Response date: 03/07/2022
Specification No. 01350 1.7.C
Specification 01350 1.7.C states the contractor's crew will need to be HAZWOPER trained if hazardous waste gases are encountered. Can the costs for this work be paid as 'extra work' and paid for in 'Bid Item 1 - Supplemental Work' if hazardous waste gases are encountered? This will save the County money since the contractor will not need to include HAZWOPER Training costs in their base bid. (RFC 46411 submitted 3/2/2022)
No. As the landfill is currently active and gasses are likely present, the Contractor's safety program and bid shall include HAZWOPER training of Contractor and their employees. Payment for this item under Supplemental Work shall not be allowed. Response date: 03/07/2022
Drawing No. 11298, Sheet 2 of 37
Please provide quantities of the two stockpiles shown, if allowed for Intermediate Soil Cover. (RFC 46436 submitted 3/3/2022)
