1. Question: We observed a red water utility cap located on the sidewalk near the proposed ramp excavation area. Based on discussions with site personnel, this cap appears to be historical and cannot be removed. It is currently unclear whether this utility is active or inactive. Request: We are requesting any available utility drawings, maps, or records that show all underground utilities (including but not limited to water, electric, gas, telecom, and sewer) in the vicinity of the proposed ramp installation area. This information is critical to ensure safe and compliant excavation during site preparation.

Answer: Drawings from a previous drainage + paving project can be provided as well as any earlier studies or historical drawings.

The red water utility cap may be historic, and if it is, its removal would need to be reviewed for Section 106 compliance and approval from the SHPO.* The project was intended to leave it in place, unless construction activities require its removal.

2. Question: We are seeking confirmation regarding the scope of railing replacement on the concrete deck. Currently, there are existing railings at both entrances on either side. While we understand that we are responsible for providing new railing for the ramp, we would like to confirm whether all existing railings that show signs of rust are to be replaced as well. The rust is particularly at the base where they enter the concrete.

Answer: Yes, all railings will be replaced due to excessive rust and lack of safe structure.

3. Question: Replacing all rusted railings would ensure visual and structural uniformity across the entire entry area. Please confirm if this approach aligns with the project intent and if we should proceed with replacing all rusted railings.

Answer: Yes

4. Question: We are requesting confirmation regarding the drainage design associated with the new concrete ramp installation at the Springfield Armory National Historic Site. The ramp will be installed approximately 2 to 3 feet away from the building and will span a length upwards of 45 feet. Given the potential for snow and wet weather conditions, it is critical to ensure that water is directed away from the building and into an appropriate drainage system, as noted

The drawing indicates a note in the upper left corner stating:"COORDINATE

TRENCH DRAIN LOCATION WITH SITE/CIVIL DRAWINGS"

We would like to confirm:1. That a trench drain is indeed planned for this area.2.

The exact location and specifications of the trench drain.3. Whether any additional drainage measures are required to ensure proper watershed management away from the building.This confirmation is essential to proceed with the ramp installation while ensuring long-term durability and water management.

Answer: The ramp project was originally planned to be part of a larger site drainage project for Springfield Armory NHS, but because the ramp scope was removed, the trench drain was not completed. The area where the ramp is planned for construction has not presented stormwater drainage issues, but this could change with the construction of the new ramp. The project includes Division 31 Earthwork specifications including Grading, Excavation, and Fill, with the intention that the site will be graded to divert stormwater away from the building.

However, due to the proximity of the window wells to the new ramp, it might be prudent to add a new trench drain to the project scope as a separate line item, as an amendment to the scope, and NPS can determine whether to include it as an option once bids are received.
