26. Questions and Answers:

o Question #l: On the Bid Form provided in Addendum 2, Items with Index numbers 8 & 9 are both Item 144 Class B Rock Excavation. There are two different quantities, what is the difference between these items?

o Answer #1: Refer to revised bid sheet within this addendum correcting the bid items and their quantities.

r Question #2: The specifications indicate that no silt producing in-water work is allowed between January l5th - June 30th and September I st - November 15th of each year. The specifications also indicate that work is not allowed between Memorial Day and Labor Day. Based on these restrictions, is it the intent to only perform work between November 1 5th and January 1 5th of each year? Will work in the water be allowed behind the cofferdam outside of the limits listed above? If so, will cofferdam installation and removal be limited to November 15th - January 15th ofeach year? Typical ACOE general permits allow for installation of cofferdams outside ofany in-water work restriction dates.

o Answer #2: Work is not limited as summarized in the question. Although silt producing in-water work is not allowed between January 15th - June 30th and

Addendum #5 Page 2

September 1st - November 15th ofeach year, work in the water behind cofferdams is allowed between January 15th - June 30th and September 1st - November 1 5th of each year. Installation and removal of the cofferdams are required to be in place prior to the time-of-year (TOY) restrictions noted above as noted in Condition #3 of the ACOE permit (Attachment G of the

Supplementary Conditions). No construction from Memorial Day weekend through Labor Day, except the Town and District Highway Director may consider approving a request from the Contractor to work between Memorial Day and June 15th as long as the proposed work activities are determined by the Town and District Highway Director to not impact traffic and are of minimal impact to the abutting business owners.

The purpose of this work is to avoid interference ofthe existing timber piles from the proposed piles construction. IfContractor's construction means and methods are such that the existing piles can be left in place without interference with the proposed piles installation, the existing piles can be left in place.

Contractor shall make his own investigation at site to determine the existing pile locations in relation to the proposed pile locations. The exact locations ofthe existing piles should be determined in the field.

O Contractor shall be careful in removing the existing piles so as not to cause disturbance or damage to the adjacent structures. Prior approval from the Engineer shall be obtained prior to the removal of existing piles. Consideration shall be given to relocation ofproposed piles to avoid interference with existing timber piles rather than having the existing timber piles removed.

@ It is anticipated that the existing timber piles were treated.

Method of Measurement

@ 'Existing Timber Pile Removal' shall be measured for payment per FT of existing timber piles removed.

Basis of Payment:

OPul-.rt for this Item shall be made at the Contract Unit Price per Foot of existing timber piles removed. The contract unit price shall be considered full compensation for all other materials, tools, equipment, labor and incidentals necessary to complete the work as specified on the Plans or as required by the Engineer.

STEEL PILE HP 12X84 T"T

The work under this item shall conform to the relevant provisions ofSection 940, Driven Piles, ofthe MassDOT Standard Specifications, Supplemental Specifications, except as modified herein.

The piles shall conform to the requirements of AASHTO M270 Grade 50. No substitution of pile size shall be permitted.

Prior to any pile installation operations, the Contractor shall submit for review and approval ofthe Engineerl\4assDOT a schedule of the proposed methods and equipment for all installation procedures, including the driven required capacity initially based upon a WEAP analysis.

As depicted in the Geotechnical Report, a Static - Cyclic (Express) Load Test (ltem 948.31) and a Dynamic Load Test by Contractor (ltem948.4l) shall be performed on a sacrificial pile prior to ordering of production piles. As identified on the boring logs in the plans, the piles shall be driven through the loose Fine Sand layer to the required capacity initially based upon the results from the Static and PDA tests on the sacrificial pile. It is recommended that the Contractor provide extra pile length to account for any variations ofthe actual pile tip elevations in the field. Any differences in pile lengths are to be resolved during construction, under the supervision of the Engineer and/or MassDOT. The sacrificial pile shall be located at a minimum of5 feet but preferably not greater than l5 feet away from the nearest production pile. It is recommended that the sacrificial pile be located at the southwest comer ofthe bridge. Additional Dynamic Load Testing shall be conducted on 2 (two) production piles, one at each abutment. Per the Geotechnical Report, one Dynamic load test on a production pile shall be at the opposite end ofthe sacrificial pile, meaning that the tested production pile is located at the northeast comer ofthe abutment. It is also required to conduct 2 (two) Dynamic load tests on the temporary pedestrian bridge piles, one at each abutment. ln summary, a total of 5

(five) Dynamic Load tests are specified for this project.

Prior to pile driving, the top 30 feet ofthe pile shall be coated with Coal Tar Epoxy in accordance with the manufacturer's recommendation.

It is anticipated that pile splicing will be required. Ifthe lengths ofpiles require splices, the splicing shall conform to its applicable Standard Specification Subsection 960.66. No splices shall be permitted within the top 20 feet of any pile. Welds shall be inspected using ultrasonic testing in accordance with the Bride Welding Code, ANSI/AASHTO/AWS Dl.5 and all Interim Revisions published by AASHTO. Welds shall be considered to be in tension. The Contractor shall submit shop drawings with the type ofprequalified splice weld(s) and procedures that would be used ifrequired.

The Contractor's attention is directed to the required sequence of installing the foundation piles for each portion ofthe integral abutment being constructed to a depth as shown on the plans and filling the hench with Crushed Stone under Item 156.13.
