Project Overview

Thomas Edison National Historical Park is a National Park Service site located in West Orange, New Jersey. The park consists of two separate sites, approximately one mile apart.

Thomas Edison’s home, Glenmont, is located in a private residential community known as Llewellyn Park. Built in 1880, Glenmont is a 29 room Victorian mansion which remains intact, complete with interior furnishings and finishes that reflect the rich historic decorative period during the years when Thomas Edison and his family resided in the home. This historic residence is currently operated as a functioning museum. Glenmont is a property of national significance that is listed on the National Register of Historic Places.

Glenmont, a prime example of Queen Anne style architecture, is a balloon framed structure which includes a circa 1880 stone foundation at the basement level with walls made of brown sandstone. This Scope of Work produces an assessment report which outlines the requirements for preservation maintenance of the north exterior stone foundation wall in basement room B14 of the Glenmont mansion. The goal is to ensure the long-term integrity and appearance of the historic structure while addressing any immediate preservation needs. A condition survey of this wall will help the park to achieve these goals.

Objectives

To survey, assess, and produce an existing conditions assessment which outlines specific steps that need to be undertaken in order to repair and/or maintain the exterior B14 north foundation wall at the Glenmont Mansion. The goal of this report is to make recommendations which will stabilize the wall as well as prevent further deterioration and water intrusion while preserving the historical significance and aesthetic character of the structure. As per National Park Service standards for historic properties, the assessment will focus on maintaining as much of the original historic fabric as is possible and only replacing in-kind any select historic materials that require upgrade in order to stabilize this deteriorating wall. To the greatest extent possible, the

Scope of Work for the Survey of the B14 Stone Basement

Foundation Wall at Thomas Edison’s Home, Glenmont

PMIS Project #246236 Thomas Edison National Historical Park

12 Honeysuckle Avenue West Orange, NJ 07052 tasks associated with implementing the findings of this report will be completed, using similar historic methods and techniques that were originally used to create the stone foundation wall. As a whole, completion of this design document (assessment and evaluation) will provide a road map that will be used to further preserve this historic home and improve the condition of its building envelope.

Existing Conditions

Stabilization and erosion issues of the north brownstone wall of Basement Room B14 have occurred due to water penetration issues as a result of a malfunctioning gutter.

Because the gutter above this location was malfunctioning, rain water penetrated the earth outside of the north wall of this basement room, creating a sinkhole which caused water to seep directly into the ground outside of this foundation wall. Consequently, water has permeated the wall on a regular basis, likely for several years.

Addressing these erosion and stability issues on this foundation wall in a timely manner is recommended in Glenmont’s Historic Structure Report: Part 2 (September of 2017) which specifically recommends that these repairs be undertaken to “minimize dampness” and to “prevent further corrosion of the dry valve and back-flow preventer equipment” as this condition issue is contributing to the “corrosion of the fittings, surfaces, and supports”. In total, this work will prevent damage to important HVAC, fire protection, and plumbing equipment located in this basement area.

Site records indicate that the Rockwell Newman Company previously undertook foundation repair work at Glenmont in the early 1970s. It is unclear whether or not those repairs included work on the north wall in the B14 basement area.

Project Location

Thomas Edison's Historic 1880 Mansion, Glenmont

Location: Llewellyn Park: 12 Honeysuckle Avenue West Orange, NJ 07052

Scope of Work

Assessment:

Visual Inspection: Conduct a thorough visual assessment/survey of the exterior B14 north stone foundation wall to identify signs of deterioration, such as:

Cracking or spalling of stones or mortar

Signs of water intrusion or moisture damage

Efflorescence or biological growth (mold, moss)

Structural concerns affecting stability

Moisture Testing: Utilize moisture meters to gauge the extent of moisture present in the stone and mortar. Make specific recommendations for repair/maintenance of the wall, based upon these findings.

Mortar and Stone Analysis: Conduct mortar and stone analysis testing to make specific recommendations for replacing these materials in-kind, as required. The mortar analysis must provide a specific formula for recreating the mortar that is currently being used for the B14 stone foundation wall.

Conduct Cleaning Tests: As required, to determine the appropriate non-invasive methods for surface preparation. The report shall detail the appropriate methods to remove dirt, debris, and biological growth and also for removing loose mortar and efflorescence without damaging the stones.

Documentation

Photographic Record: Document current conditions with detailed photographs of the stone wall foundation

Submittals: The assessment report for repairing and stabilizing the B14 basement wall at Glenmont. Submit technical information and recommendations for materials as part of the project deliverable, inclusive of mortar technical specifications and/or stone repairs.

Comprehensive Written Report: The written condition assessment for the repair and stabilization of this basement Foundation wall will include all of the associated data that was compiled during the vendor’s visual assessment of the B14 wall and its surrounding area, documenting the existing conditions. This report will summarize the findings of the visual assessment, including identified issues and recommended repairs.

The report will also include the culled data from the associated mortar and stone analysis testing, the cleaning tests for surface preparation recommendations, and the moisture testing. The report will summarize the findings of these forms of analysis.

Vendor will also produce CAD drawings of the wall as part of the written assessment: These architectural drawings will provide a percentage of how much of the wall is damaged and what exactly requires repair and/or replacement with the identified locations/areas that are specifically outlined on this diagram. These measured drawings will identify areas where stone replacement is required, where mortar upgrades/replacements are required, and also highlight the specifically identified locations of any other necessary repairs or stabilization.

Recommended Methodology: Vendor will also include in the written assessment, the recommended methodology for treatment, which must adhere to National Park Service and Department of Interior Standards for historic preservation. The recommended methodology that is outlined in the assessment of the foundation wall will include recommendations for addressing the specific issues/tasks that are outlined below.

Additionally, the assessment will make recommendations for future monitoring and cyclical maintenance for the B14 basement wall.

Repair Work

Moisture Management: Identify methodology and approach for addressing any sources of water intrusion, such as:

Improving drainage around the foundation (ensuring proper grading and functioning gutters).

Considering the installation of a French drain if necessary.

Identifying any potential recommendations for the addition of any sealant in order to enhance the area's ability to remain watertight.

Identify Methodology and Approach for Repairing Cracks and Joints:

For identified cracks, repoint using lime-based mortar compatible with historic masonry.

Fill minor voids with hydraulic cement where necessary, ensuring compatibility with existing materials.

Identify Methodology and Approach for Stabilization: Recommendations for addressing any structural concerns by consulting with a professional mason specializing in historic preservation to discuss appropriate methods of stabilization if significant issues are found.

Deliverables

The deliverable is a comprehensive assessment report of the B14 basement foundation wall at Thomas Edison’s 1880 mansion, Glenmont, containing all of the associated information that is identified in this statement of work. Four bound paper copies of the report on 8 1/2 x 11 paper, and one electronic copy of the report in PDF format on a flash drive must be submitted to the COR for this project as part of the project’s required deliverables.
