# Question Response

Drawings LP 0 01 has 5 tables, the total of these tables is approx. 12,694 trees and shrubs and the total of LP‐1‐11 to 15 is 1,155 trees and shrubs for a combined total of 13,849 trees and shrubs. Bid Item 15‐01 and 15.02 is the Upland Tree Mitigation with units of 8,000 trees and 3,000 shrubs – which of the trees and shrubs get paid in these two items and which trees, shrubs and plugs get paid in Item 16 (Wetland Riparian Plantings) at 19.081 acres?

11/8/16 addendum provided clarification on planting.

The landscape buffer drawings (LP‐1‐11‐15) shows 1,155 trees and shrubs, but the bid quantity is 8,000 trees and 3,000 shrubs for the Upland Tree Mitigation?

11/8/16 addendum provided clarification on planting.

Drawing LP-1-16 includes a table which appears to be a summary of the individual tables on drawings LP-1-11 to 15. On the summary table, the Summersweet and Pin Oak are 97 and 70 each. When you add up the individual tables the sum of the Summersweet and Pin Oak are 105 and 71 each?

11/8/16 addendum provided clarification on planting.

Technical specifications 32 90 00. This section includes:

a. Table 1A – Planting Schedule for the Restoration of Temp. Impacted Wetlands

b. Table 1B – Planting Schedule for the Created Wetlands in Former RR

ROW

c. Table 1D – Planting Schedule for the Wetland Transition Areas

d. Table 1E – Riparian Woody Riprarian Plant Schedule These tables in the specifications include the same items as the tables on Drawing LP-0-01, but are less by 2 to 3 times. Do we disregard the tables in the specifications and use the tables on drawing LP-0-01?

Revised specification in 11/8/16 addendum removed tables.

Contractor shall use tables in Drawings.

Technical specifications 32 90 00‐14, Table 1C – Planting Schedule for the Created Wetlands Adjacent to the Consolidation Area shows a total of 1,070 plugs, trees and shrubs. Are these quantities included in any of the other tables on Drawing LP‐0‐01 or do we add these trees and shrubs and plugs?

Revised specification in 11/8/16 addendum removed tables.

Contractor shall use tables in Drawings.

Bid Item 16 (Wetland Riparian Plantings) is 19.081 acres. On drawing LP‐0‐ 01, Note 5 refers to 2.612 acres of additional wetlands to be restored adjacent to existing wetlands; Note 1 at the proposed DRCC shows a total disturbance of 9.08 acres; Note 1 at the proposed woody riparian shows

4.997 acres, for a total of 16.689 acres. Are the other 2.392 acres the transition areas and streambed and bank restoration?

G001 in the Permit Drawings for the Freshwater Wetland General Permit summarizes the impact areas as follows: permanent wetland impact: 0.917 acres, temporary wetland impact 5.010 acres, temporary transition area impact: 7.809, temporary open water impact: 0.339 acres, and termporary riparian zone impact: 4.997 acres. These sum to just over 19 acres.

Drawing LP-1-11 to15 shows a swale, approx. 25’ wide:

a. What Bid Item is the construction of this swale included in?

b. Is this swale seeded with the Native Prairie Basin Mix shown on LP-1- 16? Is this mix used anywhere else?

c. Does this swale receive erosion control matting? Is the erosion mat the NAG S75 matting?

a. Site Grading: Bid Item #10.

b. Yes, see specifications for Turfs and Grasses. Addendum published 1/8/16 clarifies that this area will receive a seed mix conistent with the DRCC stream corridor restoration areas.

Q2. SPEC SECTION 01 11 00 1.06 WORK AND SEQUENCE

Will weather days be added to the 6 month duration allowed for the installation and removal of the Royce Brook Culvert?

The temporary culvert at Royce Brook cannot exceed the 6-month duration.

THERE APPEARS TO BE A CONFLICT IN THE SIZE OF STONE AND

DIMENSIONS USED FOR THE CONSTRUCTION ENTRANCES.

Drawing G 0 02, General Note 9 states: TRAFFIC CONTROL STANDARDS

REQUIRE THE INSTALLATION OF A 50’X30’X6” PAD OF 1 ½ “OR 2”

STONE, AT ALL CONSTRUCTION DRIVEWAYS, IMMEDIATELY AFTER

INITIAL SITE DISTURBANCE.

The construction entrances shall have a 1-inch minimum stone size.

The open-graded stone (or reclaimed rail ballast) used to construct the haul roads may also be used for the construction entrances.

DRAWING GC 5 02, CONSTRUCTION ENTRANCE NOTES 1-4 State the following.

1. STONE SIZE-USE 1-INCH STONE

2. LENGTH-NOT LESS THAN 50 FEET.

3. THICKNESS NO LESS THAN SIX (6) INCHES

4. WIDTH – TWELVE (12) FOOT MINIMUM, BUT NOT LESS THAN

THE FULL WIDTH AT POINTS WHERE INGRESS OR EGRESS OCCURS.

USE TWENTY-FOUR (24) FOOT WIDTH IF MAIN ENTRANCE TO SITE.

In addition, both stone sizes listed are smaller than the stone called out for use on the Temporary Construction Access Road and Site Construction Access Road (Drawing GC 5 04) and specification section 31 22 00 Par. 2.07 OPEN-GRADE Stone.

PLEASE CLARIFY THE DIMENSIONS OF THE CONSTRUCTION

ENTRANCE, AND THE SIZE OF STONE TO BE USED

The construction entrances shall have a 1-inch minimum stone size.

The open-graded stone (or reclaimed rail ballast) used to construct the haul roads may also be used for the construction entrances.

Spec Section 01 3 00-05 Submittal Procedures: 7.c: describes content of required TEP- says “methods to tarp and secure loads during transportion”

Does this include movement of material on site, not going over the road?

i.e. transport across site of material to AOC 15 Containment area?

02 81 00 Transporation and disposal do not specifically require the use of tarp during onsite hauling. However, it is recommended that contractor provide methods to tarp and secure loads during transportation offsite, and onsite - when needed. As an example, one instance where tarp may be needed for onsite transport could occur if loose, dry soil combined with windy conditions creates unacceptable dust from the truck.

Spec Section 02 81 00-5 N.

Loaded trucks shall not leave the Project Site unless they shall arrive at the designated waste management facility before it closes. Loaded trucks shall discharge their loads at the designated waste management facility the same day they are loaded.

This significantly limits radius of T&D from the project site. Please provide a list of approved disposal sites that are within a reasonable distance of the project site.

If selected disposal facility cannot be reached on the day the truck is loaded, please provide description of management procedures to be used to ensure effective management of waste materials.

Q6. Spec 01 11 00 1.04.B.3 Please provide a copy of these and any other permits already obtained by the GSA:

a. A Road Opening Permit from Hillsborough Township for temporary access to Township roads.

b. A Road Opening Permit from Somerset County for temporary access to Amwell Rd

c. A Soil Certification from Hillsborough Township to transport soil from the Site.

a&b. Road opening permit will be secured by contractor. AECOM is discussing with Township and County the details and expectations for the permit application.

c. Soil Certification description in specifications incorrectly describes this requirement and will be modified. The Township of Hillsborough will require dodcumentation that fill being brought onsite is not contaminated and meets NJDEP clean fill standards. This documentation must be submitted to the Tonwship Engineering Department at least 10-days prior to soil transporation.

Q7. Specifications Section 02 41 00, SITE DEMOLITION, 1.02 D states “Wood, metal, railroad ties, and other miscellaneous debris will be transported off site for disposal or recycling as described in the Drawings and Specifications.

There is no quantity for rail road ties or concrete debris.

Can the EPA please quantify the amount in tons of railroad ties to be removed for disposal as typically this is hazardous waste?

Addendum published 11/8/16 revises Schedule A to provide a quantity of rail ties to be disposed (in tons).

Q8. Specification Section 02 11 60, Site Demolition, 3.03 C, states that …provisions for placement of demolition debris in AOC-15 consolidation area provided in specifications section 31 22 00 Backfill & Grading.

A) What is the quantity of concrete demolition debris on the site in tons?

B) What percentage of this demolished concrete can be utilized in the AOC-15 consolidation area versus that which must be shipped off site as no-hazardous waste in tons?

C) Specification Section 31 22 00 Backfill & Grading, does not discuss how to place 6-in minus demolished concrete into the consolidation area as it does for various other types of materials (i.e., topsoil, 1” stone, etc.). What is the requirement for placing this unknown quantity (tons) of demolished concrete into the AOC-15 consolidation area?

a. estimates of conrete quantity shall be made by the contractor.

b. Contractor shall determine if concrete may be reused onsite (in the consolidation area or for other purposes) of if it must be disposed offsite. Contractor shall assume testing results indicate that all concrete can be reused onsite.

c. processed concrete for reuse in the consolidation area may be placed at the direction of the Construction Manager. In general, concrete debris will likely be placed at thicknesses no greater than 6-12 inches within the consolidation area mound.

Q9. Section 32 90 00 Planting There are several references to the “Landscape Establishment Period”. Is this the three year warranty period, or is this a different time requirement for the project?

The landscape establishment period shall be the period between planting and substantial completion.

Section 32 90 00‐10, Landscape maintenance and watering, including 4.01.E (watering twice per month): is this required during the entire 3‐year warranty period after the completion of the construction contract?

Watering is required for the 12-month period following planting and the reciept of notice of substantial completion.

The attachment, Tree Mitigation Plan – North Parcel, dated 10/17/2016, page 5, Table 2: The sum of zones A-F for the proposed additional shrubs is 3,000 plus the 1,250 shrubs for the Wetland Riparian Restoration is a total of 4,250 not 3,000?

Due to the considerable quantity of plan sheets and the limited time to provide a proposal will a CAD file for grading plan sheets (CD101 through CD134, CG101 through CG134, and CS101‐CS102) be provided by 11/3 to allow bidders to verify excavation quantities and embankment/backfill quantities?

Contractor shall base their quantities on Bid Schedule A.

2. Will the work required to restore the site to the grades as shown on plan sheets CG101 through CG134 after excavation has been completed be paid for under Bid Item 10, Site Grading? If so please provide embankment/fill quantities required to do so.

Yes grading activities on CG101 - CG134 will be paid under Bid Item #10. Cut and fill for these areas balance, so additional fill is required to meet grades. If grades cannot be met in the field, CM may approve lower grades or allow the import of fill as a change to the contract.

After digitizing the Contract Drawings we found an additional 143,000 CY of additional excavation in order to achieve the restoration grades (less topsoil). The specs & addendum instruct the bidders to assume the site is in balance but it is not in balance. How are we to deal with this excess soil?

Where do we place it? This is a significant variance. Can a unit price item be added to the bid to account for this excess excavation and where it is to be placed.

Design grades have been analyzed in Civil-3D and have been found to balance. Contractor shall assume that the quantities presented in Schedule A are accurate. Amounts in excess of the quantities on Schedule A-01 will be paid on unit rates based on Shedule A-02.

Section 01 11 00, 8. The Contractor shall dispose of chips at GSA approved off-site locations but no locations are given and Section 01 22 00, Bid Item 2, a., iv indicates the chips can be managed as non-contaminated. Please confirm there are no restrictions for the disposal of clean wood chips.

▪ Section 01 22 00, Bid Item 5, a., iii, requires the Contractor to grind stumps and roots in a tub grinder and then pass the chips generated from the grinding through a screen to remove entrained soil from the chips. Please confirm that screening wood chips in all areas is only required following tub grinder procedures required of stumps and/or roots and is not required during normal chipping of trees and brush.

Screening of chips to remove entrained soil is only required for stumps and roots and is NOT required during normal chipping of trees and brush.

▪ Section 01 22 00, Bid item 10, Site Grading, a., i., states “Assume that off-site borrow will not be required and that high spots and low spots …… will balance. Has AECOM performed the takeoff to determine if the site is in balance? Also is the Contractor expected to move existing soil from multiple zones to multiple zones in order to achieve the necessary grades? Why can’t the excavation plan be modified to incorporate the proposed final grades?

Designer has performed analysis in Civil-3D and has found that the design grades are in balance. It is possible that some 10-acre areas will have excess or require soil to meet proposed design grades.

Contractor will work with CM to address identified issues in the field.

The excavation plan is designed to remove impacted soil while limiting the colume to be moved to the consolidation area and will not be modified further.

▪ Section 01 22 00, Bid item 11, Bid item 14, topsoil and seed. Has the government considered utilizing any of the existing on-site topsoil in lieu of importing roughly 250,000 cubic yards?
