About this file
This document is a pre-bid site visit summary for the Home of FDR (HOFR) Rose Garden Infrastructure Rehabilitation project. On June 11th, 2025, three potential offerors participated in a site walkthrough at the Wallace Visitor Center, meeting with key National Park Service personnel including the COR, Integrated Resources Manager, Horticulturalist, Gardener, and Facilities Manager. During the visit, three primary questions were addressed: (1) asphalt path thickness details, confirmed through a physical probe showing multiple asphalt layers ranging from 1.5" to 4" thick, (2) project completion timing considerations, specifically emphasizing the need to complete sod planting with sufficient time for root establishment before winter, and (3) tree and stump removal requirements along the east pathway, with specific instructions to use air spade excavation techniques within the critical root zone of remaining trees.

Home of FDR (HOFR)
Rehabilitate the Rose Garden Infrastructure
Pre-bid Site Visit, June 11th, 2025.
Summary:
The pre-bid walk-thru occurred on Wednesday, June 11th at 10am EDT. Three parties representing two potential offers met in front of the Wallace Visitor Center to sign in and have a brief introduction to the site and to meet the key parties from within the park, namely Craig Oleszewski (ROVA COR for the project) Christopher Pray (ROVA Integrated Resources Manager) Anna deCordova (ROVA Horticulturalist) and Susan McAvery (ROVA Gardener). The parties walked to the Rose Garden where they were all joined by Mike Riegle (ROVA Facilities Manager). The weather was fair, partly cloudy with temperature in the 70’s and a gentle breeze. These are optimal conditions for observing the garden. Attendees stayed together as a group and moved through the garden to the area at the south where the dry-well will be placed.
Questions and Answers.
Few questions were raised that were not addressed by the contract documents:
1.) What is the thickness of the asphalt in the paths to the Garden?
a. NPS conducted a physical probe (dug a hole) along the western edge of the west path that leads to the south entrance to the Rose Garden. The attached photo and diagram show that the asphalt in that location is approximately 1.5” thick at the surface layer. The next course down is likely a binder layer that is 2.5” thick and extends an additional 2” beyond the visible edge of the surface layer. There is another course below that which is 4” thick and extends 8”. See the accompanying sketch and photo.
2.) Is there a deadline for completing the project?
a. One of the final steps in the project is to lay sod and that cannot happen too late in the year. Sod planting will need to happen with enough time for healthy root establishment before winter conditions set in. The offeror will need to address this along with other phasing and staging issues in the proposal as detailed in the project documents.
3.) Trees bordering the east pathway to the Rode Garden have been recently removed. Sheet C2.1 states that the stumps and roots are to be removed within the proposed pathway.
There is a further note that the excavation within the critical root zone must be with air spade.
a. Offeror’s proposal must address means and methods for achieving the result of removing the stumps and roots to sufficiently clear the zone for the pathway while utilizing the air spade for any excavation occurring within the critical root zone of existing trees to remain.
