Point Arena Pier Repair—Bid #2021-02
Addendum July 16, 2021
Question 1: Are there any technical specifications provided other than the notes on the plans?
Response 1: All technical specifications are on the notes on the plans.
Question 2: The permit and plans prohibit impact pile driving and jetting this only leaves vibratory as the pile installation method. Is vibratory the desired pile installation method?
Response 2: Yes—vibratory is the desired method.
Question 3: Is there any specific size/ energy required for the vibratory hammer?
Response 3: No—there is no specific size/energy required for the vibratory hammer.
Question 4: The permit states that all equipment used on the pier MUST use vegetable based hydraulic oil. Does this requirement only apply to the piledriving equipment? Does it also apply to any crane or other lifting device used on the pier? Would it also apply to a fork lift used to shuttle piles out to the pier?
Response 4: Yes—the requirement applies to any crane or other lifting device used on the pier.
Question 5: The permit specifically states that any cutting and drilling of the pile and application of the topical preservative must be done 100′ away from the water however how is it possible to notch the pile for the U bolt (shown on sheet C-2 Section A) drill the pile at the required location, or cut the pile off at the proper elevation since no one can pre determine the exact location/ elevation that will be required for cutting until after the pile is driven?
Response 5: See Note 4(F) on sheet G-2 of the project plans, which provides guidance on unavoidable cutting/drilling in place on the pier.
Question 6: Is there any specified minimum embedment for the wood piles? What happens if the pile hits an underground obstruction?
Response 6: No—there is no minimum embedment for the wood piles. Any underground obstruction will be considered an unforeseen underground condition and a solution will be determined during construction.
Question 7: The plans state to drive the guide pile to refusal. What is the acceptable determination of refusal?
Response 7: Piles should be driven to the maximum depth possible given the strength of the pile material and site conditions.
Question 8: The plans require cutting the pile off 2′ below the surface. What methods can be used to cut the piles 2′ under the surface?
Response 8: Bid the project per the specs, and assume the pile to be cut as far below the surface as site conditions allow.
Question 9: The plans state the level of pile treatment/ retention of ACZA is to be in accordance with AWPA guidelines for the application. Normally the engineer determines the level of treatment required. This is very ambiguous. Can you provide the required/ desired treatment retention?
Response 9: See Response 10 below.
Question 10: The ACZA treatment consists of Ammonia, copper, zinc, and arsenic. The permit and plans state there can be no obvious ammonia odor. Piles treated with ACZA can have an ammonia odor for a year or more. How is it possible to obtain ACZA treated piles that do not have an ammonia odor? How can the acceptable level of ammonia odor be determined?
Response 10: The level of treatment should be light enough such that the piles do not have a strong ammonia odor. The level of treatment should be selected to minimize the odor of ammonia.
Question 11: The plans state that piles must be stored away from the water. Will the contractor be provided an appropriate storage area?
Response 11: Yes—on-site storage will be provided.
Question 12: The plans do not specify a length for the plastic wrap. What is the length for the wrap?
Response 12: The wrap will cover as much of the submerged portion of the pile as feasible, up to the pier attachment.
Question 13: The plans do not specify a length for the wood piles. What is the length?
Response 13: For context, the most recent replacement pile installed along the pier had a 50-foot pre-cut length. Other historical data on pre-cut pile lengths indicate that lengths have ranged from 42 feet to 50 feet. For this project, the pre-cut length will be what is required to reach the pier attachment after being driven to refusal.
Question 14: Is there any coating required for the new guide pile?
Response 14: No—there is not any coating required for the new guide piles.
Question 15: What is the allowed load/ capacity for placing a crane on the pier?
Response 15: There is no published maximum load/capacity for the pier. Please bid the project assuming the lightest equipment required to successfully complete the project.
Question 16: Are there specifications for the rubber buffer? Is there an approved supplier for this product?
Response 16: No—it is the intent to find a match as close as possible to the existing material.
Question 17: What grade of stainless steel is required for the U bolt and fasteners?
Response 17: See Fender Pile Note on Sheet C-1, which requires all fender pile hardware to be grade 304 stainless steel.
Question 18: What is the specification for the pile wrap?
Response 18: There is no specification. The intent is that a product that is durable and meets the project needs should be selected.
Question 19: The Coastal Development Permit states on page 6, item 5 that post construction monitoring and maintenance is required for the life of the piles. Who is responsible for this item?
Response 19: The City of Point Arena is responsible for post-construction monitoring and maintenance.
Question 20: Same permit page 6 item 6A, who is responsible for the onsite observers?
Response 20: The City of Point Arena is responsible for arranging the on-site observers.
