Same section further stipulates that Pier 6 to be done in first construction season and work on Pier 7 to be performed during the second construction season. As per the maximum number of working days allowed (240), meeting this requirement (completing one pier during one season and the other pier during the following season) is not possible as there will be only one construction season/window (July 5th thru October 31st 2019).

Inquiry #44: Our inquiry is prefaced with the following:
• Section 49-2 of the Standard Specifications provides the specifications for driven piling.
• Standard Specification Section 49-2.01A(4)(c) “Department Acceptance” provides the acceptance criteria for driven piles. The Special Provisions replace this section with “Not Used”. Driven piles on this project will thus not be evaluated for acceptance under this section.
• Standard Specification Section 49-2.01C(2) requires the use of an authorized impact hammer to install driven piles, and clearly states that vibratory hammers, oscillators, or rotators are not to be used. The Special Provisions adds to this section a requirement to use vibratory hammers, rotators, or oscillators. The Special Provisions do not delete the requirement to use an impact hammer.
• Standard Specification Section 49-2.01C(3) “Drilling” allows, if necessary to obtain the specified tip elevation and if authorized, drilling of holes with a diameter not greater than the least dimension of the pile to the specified depth before driving piles with the impact hammer.
Please respond to the following questions:
1. Is the use of an impact hammer required, or simply an option, to drive the piles?
2. When using rotators or oscillators to install steel pipe casings and piles, the usual practice is to drill the interior of the casing out to a certain depth as the pipe is advanced into the ground. This activity is not considered pre-drilling, as the steel pipe is advanced ahead of the drilling work. If either an oscillator or rotator is used to install the piles, will the State allow the interior of the pile to be drilled out as the pile is advanced, and if so, to what depth?
3. If using either and impact or vibratory hammer to install the piles, will pre-drilling be allowed, and if so, to what depth?

Response #2:
1. Refer to section 49-2.01C(2) of the Special Provisions. The Special Provisions override the Standard Specification, so impact hammers are not allowed.

2. Section 49-2.01A(4) requirements are removed for the fender piles, hence bearing is not required and only pile tip is required. Center-relief drilling may not be necessary, but will be allowed if authorized.

3. Refer to section 49-2.01C(2) of the Special Provisions. The Special Provisions override the Standard Specifications, so impact hammers are not allowed. Refer to section 49-2.01C(4) of the Standard Specifications which states that predrilled holes are for piles to be driven through embankments, hence predrilling is not allowed.

Response #2:
The plans specify HDPE thermoplastic material is required. Section 57-3.02 of the Standard Plans provide material requirements and optional plastic lumber types (RPL, CPL) for the sheathing. The 4x12 nominal cross section of the HDPE sheathing (plastic lumber) not shown in the table is because it does not require those material properties. Bid per the current contract bid documents.

Inquiry #49: Requesting further clarification to inquiry 24:

Is the disposal of timber beams, piles, and sheathing intended to be covered under the bridge removal item if the wood is not treated?

Is the treated wood waste item and quantity only a partial quantity of the bridge removal disposal quantity or is it meant to cover all wood disposal?

It seems that all wood in the structure would have been treated because it's a marine environment.

Inquiry submitted 10/10/2018

Response #1:
(#49)-Everything involved with removing the bridge is covered under the bridge removal item. You are entitled to additional compensation for the extra steps required to handle and dispose of treated wood waste.

Inquiry #51: Section 45-2.02D requires the fiberglass reinforced grating must be a one piece pultruded grating and a 2 inch square mesh configuration

Pultruded grating is not made in a 2 in square mesh configuration. Pultruded grating is constructed with tie bars at a specified spacing, usually from 4-6".

The details on the contract drawings seem to indicate a grating constructed with a mesh pattern and no tie bars.

Please clarify the requirements. If a mesh pattern is desired, it will not be pultruded. If pultruded grating is required, please specify the tie bar spacing, or percentage of open area required.

Inquiry submitted 10/12/2018

Response #1:
(#51)-Please refer to Addendum No. 5, dated October 12, 2018. The “2- inch mesh” term was incorrect and replaced.
