Scope of Work

Replace the Knox-Tindle HVAC System

Valley Forge National Historical Park (VAFO) King of Prussia, PA

Prepared by: James Moore Date: 20 March 2020

1) Background

a) This Scope of Work (SOW) is for the Knox-Tindle House located in Radnor Township, Chester County Pennsylvania. The work will be performed at the Knox-Tindle House within Valley Forge National Historical Park. The location of the work is 100 Knox Tindle Lane, Wayne, PA 19087

i) The location of the work is shown in Attachment C.

b) The Knox-Tindle House was built in 1910 for Philander C. Knox, Senator, Attorney General and Secretary of State, for one of his children. It was designed by R. Brognard Okie of Duhring, Okie and Ziegler, Architects, Philadelphia, who was a most successful exponent of the Pennsylvania neo-Colonial stone farmhouse genre. Later alterations (probably ca 1950) consist of finishing the attic to provide two more bedrooms and a bath, with concurrent installation of dormer windows and changing of the upper stair from enclosed to open type. The house remained in the Knox-Tindle family until its acquisition by the State in 1965.

c) This project consists of the base bid and two (2) options. The option(s) shall be accepted or rejected as part of the work at the sole discretion of the National Park Service, and may be accepted individually or in any combination up to the ninetieth day of the contract should funding become available with adjustments to the contract schedule as identified in section 8.0.

d) The paints and washes on the woodwork and masonry of the interior, as well as other finishes and materials, may contain lead and asbestos. The contractor shall identify all areas that will require disturbance as part of each portion of this project and test these areas for the existence of lead and asbestos prior to any disturbance.

e) The base bid includes design and replacement of the existing HVAC system, two plumbing repairs and all associated work. Bid option 1 is for repairs to the chimney flashing and associated damage caused by the flashing leaking. Bid option 2 is for the remediation/encapsulation of lead and asbestos on the interior surfaces throughout the house.

i) Base bid: The existing, approximately 25 year old, forced air system within the Knox Tindle House has exceeded its typical life expectancy. Replacement of the existing forced air system will provide energy-efficient heating and cooling and the ability to maintain the wood floors and other interior components and finishes.

ii) Bid option 1: The existing North chimney has been leaking and has caused damage to the interior finishes. This Option will require the replacement of the chimney flashing, inspection for other damages at the chimney and repairs to the surfaces damaged from the leak.

iii) Bid option 2: Previously completed lead and asbestos reports show the existence of lead and asbestos throughout the interior of the house. Because this is potentially child occupied housing, all lead and asbestos will require abatement with products that guarantee 20 years of protection.

Contractor shall also follow the Secretary of the Interior’s Standards for the Treatment of Historic Properties. Contractor shall plan, schedule, coordinate, and assure effective performance to provide the services required.

(1) Replace the existing heating system with a new HVAC system that is sized appropriately, efficient and minimally intrusive to the existing structure. This item will include demolition of the old system and design for the new system as well as the installation of the new system and all components. Also, this item will include two plumbing repairs as identified in section 4.0.

(2) As part of the design portion of the HVAC scope, the contractor shall identify all areas that will require disturbance of the existing fabrics. These areas shall be tested by a licensed lab, certified by the EPA and the Commonwealth of Pennsylvania, for the presence of lead and asbestos.

(a) Should the tests come back positive for lead and/or asbestos, all demolition, repairs, paint preparation, scraping, sanding, cutting and disturbance of the identified areas shall be performed by licensed asbestos and lead workers under the direct supervision of a supervisor with current certifications and licensing, as required, in the Commonwealth of Pennsylvania and the EPA, and shall be undertaken in a manner to prevent the release of lead and asbestos into the environment, and that does not create further lead and asbestos hazards.

(b) Regardless of the actual lead or asbestos content of the existing paints, washes or other finishes on the structure, Proper procedures are required to contain and control all the paint dust, chips, flakes and fibers that are created or released during the work to areas requiring disturbance as part of this scope of work.

(i) This will include, as a minimum, the use of plastic sheeting on the ground under the work areas to catch such debris. Positive lead test shall require all horizontal surfaces where lead paint flakes and dust may collect to be HEPA vacuumed and wet wiped to remove loose debris. Loose paint flakes and dust shall be collected, containerized and disposed of in accordance with state and federal hazardous waste regulations.

(3) Any painted surface that has lead or asbestos content should not be sanded, demolished or disturbed without the proper engineering controls and work methods, as spelled out under OSHA’s 29 CFR Part 1926.62 Lead Exposure in Construction, Interim Rule.
