Subject: Concrete Cylinder Pile Spec - Equipment 4B Type: Specifications
Question Date: 8/20/2019 12:18:28 PM
The refenced specification states that "Diesel hammers will not be allowed to drive cylinder piles." The only hammers allowed are air, steam, or hydraulic. These types of hammers have very limited availability and are not guaranteed to be available for this project. Diesel hammers are much more readily available and have been recently utilized on projects to drive concrete cylinder piles. We ask that the owner, please reevaluate the possibility to utilizing diesel hammers to install the concrete cylinder piles.

Subject: As-Builts Type: Plan
Question Date: 8/1/2019 12:50:26 PM
We concur with the question asked on 7-8-19. The original plans do not have any cross-section views and the only information are some standard plans from 1957. Without some idea of what the superstructure is and how it was built, it makes it very difficult to determine quantities, pick weights, etc. Could the department please provide some more detail, past inspections, the referenced plans and/or any rehab drawings. Thank You.

Subject: Temporary Sheet Piling and Cofferdam Quantities Type: Bid Sheet
Question Date: 7/29/2019 10:07:07 AM
Contractor is seeking clarification as to the methodology of establishing quantities and scope within proposal line number 1130 (Temporary Sheet Piling) and 1240 (Cofferdam). Per the ** footnote under each of the "Estimated Quantities - Substructure Only" tables, the cofferdam quantity is to be used for the removal of existing structure. Four cofferdams for this purpose are shown on the succeeding drawing, however these four cofferdams are also labeled as "temporary sheet pile cofferdams typ.". Please clarify where the remaining two cofferdams for removal of existing structure are to be located (for a bid quantity of 6 per bridge), and please clarify if the four cofferdams shown on the drawing are to be included in bid line item 1130 or 1240.

Subject: Removal of Existing Piers Type: Specifications
Question Date: 7/9/2019 9:13:39 AM
The 413.02(a) standard specification states, "The substructure shall be removed down to the streambed or to an elevation of at least 2 feet below the natural ground." It appears that some of the pile caps/footings are less than 2' below the streambed. Please clarify if the contractor is to remove the entire pile cap/footing or if its acceptable to demo down to top of pile cap/footing. Also, what are the allowable means and methods for removal?

Subject: Cofferdams at Proposed Piers Type: Plan
Question Date: 7/9/2019 8:08:43 AM
The plans show cofferdams to be constructed for the construction of the new piers. However, the pile are to be cutoff 10' above waterline and a precast cap sits on top of the pile. So, this leads us to believe this is no 'in water work'. Please clarify the intention of the cofferdams at the proposed piers.  
Answer   Date: 7/18/2019 8:31:00 AM
The intention of the cofferdams is to create a dry work area for pile driving
