QUESTION/COMMENT/REQUEST FROM RFI #1:

With regard to the Clearing Site Spec Section 201, it appears that this Spec Section is applicable for other projects but not specifically for this project. As a result this creates unnecessary confusion when Bidders are trying to interpret the Scope of Work that is to be included in the Lump Sum Bid Item #27. In order to eliminate this confusion we request that Section 201 be revised to remove all irrelevant requirements and statements that are not applicable to this project. Here are just some examples of items found on Page 200-1 that are not applicable to this project and that should be deleted from Spec Section 201.

Paragraph #2 should be deleted because it states that Clearing Site shall include the cost of restoring all landscaping within the limits of construction.

Paragraph #3 should be deleted because it requires all railroad tracks to be removed and salvaged.

Paragraph #6 references the need to remove and salvage utility poles, guy wires, and appurtenances.

Paragraph #7 references the need to remove existing guide rail end treatments.

Paragraph #12 references the need to remove and dispose of existing HMA or concrete pavement but the Demolition Drawings do not call-out any existing pavements to be removed.

RESPONSE:

Paragraphs #2, #3, #6, #7, and #12 are not applicable. Should additional clearing site become necessary during the duration of the contract; the Bid Item #46 Allowance for Work Unspecified may be utilized for additional compensation for same.

QUESTION/COMMENT/REQUEST FROM RFI #1:

The Clearing Site Scope of Work is shown on Demolition Dwg’s GT-5, GT-6 & GT-7. With regard to the Clearing Site Scope of Work identified on these drawings, please address and clarify the following:

Existing Fence is called-out on Dwg GT-7 to be removed or relocated but the drawings do provided a Symbol for Fence Removal or Relocation, and it is not clear as to how much of the existing fence is to removed. Please identify the quantity of existing fence that is to be removed or relocated.

According to the call-outs, there is existing fence and at least two existing gates that are to be relocated, but there is no information provided on the drawings that indicates where or how the existing fence and gates are to be relocated. Please show the proposed locations of the relocated fence and gates, and also provide construction details for this fence and gate relocation work that indicate whether or not barbed wire or footings are required, etc.

Because the drawings indiscriminately use a very ambiguous symbol (a circle with an cross) to indicate “structures” that are to be removed it is not possible to determine what types of “structures” are to be removed or the cost of removing these “structures”. Please identify what types of “structures” are to be removed on these drawings so that fixed pricing for this work can be provided.

The drawings call-out a couple of existing “structures” and state that these existing structures are to be evaluated and removed. Please explain what this statement means, and clarify if the Bidders are to exclude the cost of removing those structures (to be evaluated) from the Lump Sum Bid Item #27.

Various underground sanitary sewer and drainage pipes and related structures are called-out for removal, but the drawings do not provide the lengths of pipe that are to be removed, the diameter of those pipes, the types of pipe (RCP, DIP, etc.) that are to be removed, the depths of the pipes, or the type of backfill to be used for backfilling the trenches. Without this type of basic information it is not possible for Bidders to provide firm Lump Sum Pricing for this removal work. Please provide the missing information.

Dwg GT-6 appears to identify one of the existing drainage pipes as 8” RCP. However, RCP is not made that small. Maybe it was intended to be 18” RCP? Please provide the correct size of the drainage pipe.

The drawings indicate that existing Jersey Barriers are to be relocated. Please indicate where these Jersey Barriers are to be relocated.

An Electric Box is called-out on Dwg GT-6 to be removed. Please clarify whether or not there are live wires that feed this Electrical Box, and if so, then please clarify what is to be done with the live wires.

An existing Clean-Out is to be removed on Dwg GT-6 but no details are provided for this work. Please clarify the scope of work involving the removal of the existing Clean-Out, which we assume will need to be cut and capped in some manner and at a specified depth below grade.

There is existing Asphalt identified on Dwg GT-6. What is to be done with this existing Asphalt?

RESPONSE:

There are approximately 555 LF of existing fence that are mounted on barrier curbs and approximately 725 LF of existing fence that are mounted with concrete footings. There are approximately (7) permanently fixed gates mounted with concrete footings, three (3) of which are 30’±, one (1) of which is 24’±, two (2) of which are 13’±, and one (1) of which is 10’±.

Existing fencing and gates that are located within the construction area should be relocated along the limit of disturbance along Kellogg Street. Remaining fencing and gates that are not relocated shall be disposed. Contractor shall provide additional temporary fence and gates, as needed, to secure site from general public. Temporary fencing can be mounted on jersey barriers or ballasts. Fence height shall match existing on-site fence height.

Structures that are not labeled on the Demolition Plans are unknown as per the “Boundary and Topographic Survey” as prepared by Langan Engineering and Environmental Services, Inc., dated June 2019 with no revisions.

Structures labeled “To Be Evaluated and Removed” are unknown and not labeled on the “Boundary and Topographic Survey” as prepared by Langan Engineering and Environmental Services, Inc., dated June 2019 with no revisions, and provided in Appendix 12 of the Specifications and Contract Documents. These structures are to be fully removed from the site.

All as-built information is as shown on the “Boundary and Topographic Survey” as prepared by Langan Engineering and Environmental Services, Inc., dated June 2019 with no revisions, and provided in Appendix 12 of the Specifications and Contract Documents. Locations on drawings can be scaled for removal, etc.

The existing drainage pipe shown on Dwg GT-6 is labeled as 8” RCP on the “Boundary and Topographic Survey” as prepared by Langan Engineering and Environmental Services, Inc., dated June 2019 with no revisions.

Existing jersey barriers should be relocated outside of the construction area and along the outside edge of the project limits, primarily along Kellogg Street.

The bidder should anticipate that there are live wires feeding the electric box. Bidder shall confirm same and coordinate with the respective utility company before removing the box.

The bidder should assume that a full removal of the existing 8” Clean-Out will be required. Cutting and capping the existing 8” Clean-Out will not need required.

All existing asphalt will remain. The existing asphalt serves as an environmental cap for the site. Please refer to Deed Notice #11, as provided in Appendix #10 of the Specifications and Contract Documents, for further detail, explanation, restrictions, and requirements for any work that is performed within the SA-6S Residential limits.

The Contractor is directed to Appendix 8 of the Project Specifications titled “Memorandum Prepared for the JCRA by Potomac-Hudson Environmental, Inc. as LSRP for the JCRA for Study Area 6 South (SA6S) Dated October 16, 2020.” On Page 2 of the memorandum, it states:

“Pursuant to the NJDEP Fill Material Guidance for SRP Sites dated April 2015 both Alternative Fill and Clean Fill requires that laboratory analytical data be provided for samples obtained from the respective material. The applicable sample frequencies for these two materials are provided in the April 2015 guidance document and in reality, are the same. The sampling frequency tables are attached for both fill types. In both cases the material should be analyzed for the Target Analyte List (TAL) / Target Compound List (TCL) plus 30, Extractable Petroleum Hydrocarbons (EPH) and for hexavalent chromium (specific to the Phase 1 Redevelopment Area). In order for any Alternative Fill or Clean Fill to be accepted, the appropriate number of samples should be collected and analyzed. Whenever licensed quarry/mine material, certified as such by the quarry/mine operator, is delivered to a property undergoing remediation, the certification can be relied upon without sampling the delivered licensed quarry/mine material.”
