STATEMENT OF WORK

Title of Project: Interchangeable walkway and liaison services to aid in the Measurements and Dissemination of the Coefficient of Friction (CF) of Footwear on Slope Roof Surface.

The services contemplated under this contract are considered to be “Other Functions” as defined by the Office of Federal Procurement Policy in OFPP letter 11-01 and by HHS in Acquisition Policy Memorandum 2012-01.

C.1 Background and Need –

Roofers potentially experience both Traumatic Injuries (TIs) and Musculoskeletal Disorders (MSDs) due to their particular work environment. We hypothesize that many injuries may directly or indirectly result from the exposure to the same physical hazards such as sloped roof surface, awkward working posture, and forceful actions or overexertion. The contracted work is a part of our project that will systematically investigate the effects of footwear on safety and MSDs among roofers and the related influencing factors. The most important physical factor that directly determines the slip/fall potential is the dynamic coefficient of friction (CF) between footwear and roof surface. While many CF studies have been reported, no study on the footwear CF on a sloped roof surface was found in the current literature. Furthermore, the available methods may not be directly applicable to measure the in-situ CF on a sloped roof surface. Different from many metallic engineering materials, the CF between footwear and roofing surface may be dependent on the normal contact force. Therefore, the measurements of the CF should be performed by applying different contact force. In order to perform the study of the friction characteristics between the footwear and roofing surface, we need many different components to complete the study.

C.2 Project Objective – To develop interchangeable walking pathways of various roof coverings they can be rapidly exchanged during a human subject testing session for measuring the in-situ coefficient of friction (CF) of footwear on roofing surfaces.

Coupled with the development and deployment of the interchangeable walkway, the vendor will also offer consultation for project refinement as well as data interpretation and liaison services with local construction companies.

C.3 Scope of Work

Is to develop, build and deploy interchangeable walkways. Each walkway will need to be able to be affixed to the sloped roofing simulator located in the biomechanics lab (H3608) at NIOSH Morgantown. The interchangeable walkways will be used in testing the effect different roofing covers have on walking and posture while on a sloped roofing environment in various footwear. The specially designed interchangeable walkway system should satisfy seven requirements: (1) walkways should be able to be changed in less than 5 minutes; (2) the walkways should function at each of the sloped roofing simulator’s positions (slope 0°, 15°, and 30°); (3) the walkways should allow for both cross slope and up/down slope walking; (4) the width of each walkway should be three feet; (5) the length for the cross slope portion should be sixteen feet and for the up/down slope portion, the length should be eight feet; (5) the total number of walkway materials to be constructed will be six (Tyvek no slip underlayment, Tyvek underlayment, Felt Roof Deck Protection underlayment, Owens Corning Oakridge Laminated Architectural Roof Shingles, and American Slate roof tiles); (6) the walkways must be exchangeable without assistance from mechanical devices to ensure quick set-up times; (7) the walkways must incorporate the force plates in a seamless manner to guarantee accurate ground reaction force collection. In addition, the vendor will offer consultation for project refinement and data interpretation. Furthermore, the vendor will provide liaison services with local construction companies and NIOSH given the technical requirements outlined in section C.4. At no time will the vendor interact with subjects nor partake in data collection.

C.4 Technical Requirements –

The researchers should provide the required liaison services and they should meet the following technical requirements:

(1) They have good knowledge and experiences in the measurements and analyses of the biomechanical and mechanical analyses.

(2) They have conducted some experimental studies on the ergonomics of roofing workers, which may also be proved from their publications or their graduate students’ theses.

(3) They should be able to provide direct guidance on the study by participating in the preparation and experiments in our motion analysis lab.

(4) They have prior relationships with local roofing construction companies.

(5) They will provide a technical report on the scientific evaluation of the effectiveness of the device.

C.5 Reporting Schedule –

• The first walkway should be constructed and delivered for initial testing on/before December 30, 2020.

• The remaining walkways will be working to desired specifications and the final written report will be delivered on/before May 31, 2021.

• A mid-contract presentation reporting on the status of potential contacts of local construction companies will be on/before April 30, 2022.

• An end-of-contract presentation reporting on the status of potential contacts of local construction companies will be on/before September 30, 2022.
