SOLICITATION NO: W91ZRS-18-R-0002 (PROJECT NUMBER: CEKT139029) CONSTRUCT BASE ENTRY COMPLEX, BRADLEY AIR NATIONAL GUARD BASE, EAST GRANBY, CT

RFIS ANSWERS DATE ANSWERED

There was discussion at the pre-bid meeting regarding requirements of the General Contractor for the management and re-use of the top 9 inches of existing topsoil. The contract documents do not address this requirement. Please provide stockpile areas and management requirements.

Due to historic presence of contaminated soils on Base, no excavated soils are to be removed from Base Property (the job site area). Any excavated soils are to be stockpiled on site. Stockpiled soils, where not required to be covered with topsoil and seeded for erosion control or other "best practices" reasons, are to be left exposed (not covered) per CT DEEP recommendations. Beyond this, there are no specific contaminated soils remediation measures associated with this project. 8/8/2018

Reference Utility Company TX Pad site. Are bollards required at the TX pad location? In an on-site meeting with EVERSOURCE, the EVERSOURCE technician indicated that he would like to see three 8-inch diameter bollards (Utility Protection Bollards) provided around the transformer pad. We also recommend additional Utility Protection Bollards around the proposed lift gate operator and sensor mounting equipment. We have modified Drawing CU101 to reflect these changes.

8/8/2018

Reference "Force Protection Bollard Detail" on CD104. Please locate these bollard types. The (5) bollards identified as "K-8 Rated Force Protection" bollards on Sheet CD104 will be changed to read "Utility Protection Bollard Detail." Locations for use of these bollards are depicted on Sheet CL101.

Note: There are now (4) Types of Bollards:

(10) 6" Removable Bollards (See CD103);

(12) Security Bollards w Covers (7-11/LS504);

(5) Pipe Bollards w Covers (Details 4-6/LS504);

(3) 8" Utility Protection Bollards (See CD104);

Note: Security bollards have the same covers as the pipe bollards. Reference on the drawings for the covers for the security bollards refers to details 8 & 9 but should refer to details 4-6. We will revise Detail 9, Sheet LS504 to "Refer to Details 4-6/LS504." Detail 8, Sheet LS504 shall refer to details 9-11, not just 9 and 11.

Areas of OLI # 1 and # 3 decorative concrete paving, the thickness and reinforcing of the concrete is not detailed for the vehicular concrete or the island cap concrete. Please provide details.

We have provided an additional section for the concrete in the drive lane (8-inches of Portland cement concrete over 8 inches of processed aggregate, called Concrete Pavement Section) and concrete cap in the curbed islands (5 inches of Portland cement concrete over 6 inches of processed aggregate base course called Curbed Island & Median Detail Sections). These sections have been added to the plan set via addition of Sheet CD105. The decorative concrete paving will consist of a stamped pattern color-enhanced Portland cement concrete. The specific pattern and color is stated in a specification excerpt attached to this document - namely (and among others) "Color: Basis of design is Bomacron Steadman Buff" (or approved equal) and "Imprinting Tools: Basis of design is Bomacron Herringbone Used Brick" (or approved equal).

As this is primarily a horizontal construction project and there is a specific schedule of tests to be conducted we are not sure how the described Subfactor 3 pertains to this solicitation, nor do we find any specific requirements for an On-site Quality Control Manager.

Almost all Quality Control is called out to be by independent testing companies

Submit a proposal in accordance with Sections 00110 and 00120 of the solicitation.
