BASIS OF DESIGN

1.0 Project Description

Roof Fall Protection per the Statement of Work, 3. Scope of Design originally included Buildings 01, 03, 22, 24, 27, 28, 31, 36 and

Outpatient Clinic (OPC). After site investigations, it was determined that some of these buildings had existing Fall Protection in place, or other types of roofing that would lend itself to a different type of

Fall Protection.

With the submission of ‘Field Visit RFIs’ and subsequent VA response, the design to include Fall Protection System has deleted Buildings 25, 27 and 36, as well as some portions of the other buildings from the

Scope, and added/included Building 02. With the submission of the 100%

Construction Documents, the VA has added/included Building 32 and the

Pharmacy roof on Building 01.

Design will provide ease of access and maintenance not limited to solar panels, service lights, cameras, HVAC equipment, roof drains, PV inverters, skylights, windows, and unprotected access at roof access ladders.

VA Fresno Fall Protection: Structural Basis of Design

Project Description

The VA Fresno Healthcare Campus has several buildings with roofs that do not have permanent ladders, tieback anchors, or parapets tall enough to serve as fall protection for maintenance workers.

This project seeks to remedy such inadequacies by installing ladders for better access to penthouse roofs, erecting guardrails along roof perimeters, or adding tieback anchors where guardrails are not feasible or practical.

Governing Codes & Design Criteria

The codes used for design of new connections and analysis of existing structure are as follows:

• IBC 2021

• VA H-18-8

• VA PSRDM 2020

• ASCE 7-16

• ACI 318-19

• TMS 402/602-16

• AISC 360-16 and AISC 341-16

Additionally, the project Statement of Work provided by the VA dictated adherence to the following codes sections:

• American National Standards Institute, Z359.1-2007, A10.32

• Occupational Safety and Health Administrations (OSHA): Title 29, Chapter XVII, Parts 1910 and 1926.

• CAL-OSHA Title 8, Section 1670, Article 24, Fall Protection.

The corresponding loads, provided on S-000 of the drawings, are as follows:.

• One 200-lb point load outward or downward applied at the top of guardrail per OSHA

§1910.29(b)(3) and OSHA § 1926.502(b)(3)

• One 150-lb point load outward or downward applied at midrails or posts per OSHA

§1910.29(b)(5) & OSHA § 1926.502(b)(5)

• Tieback anchor capacity of 5000 lbs applied in any direction per OSHA §1926.502(d)(15)

• 3000 lbs live load applied in any direction to tieback anchors per OSHA §1926.502(e)(2)

• Two 250-lb point loads acting on a ladder concurrently per OSHA §1926.1053(a)(1)(iii)

• One 250-lb point load on any rung or portion of a ladder per OSHA §1926.1053(a)(1)(iii)

Engineering Approach

Guardrails posed a unique challenge due to the variety of conditions and unknown connections or parapet composition. Small baseplates attached to the tops of parapets are feasible for concrete parapets, while face-of-parapet connections were required at CMU parapet conditions and where the parapets were formed of the light-gage construction.

S_OBrien Snapshot

GPLA, Inc. 10/29/2024 Structural Engineers & Builders 95% Construction Documents

Where the parapet was not tall or strong enough, slab or deck attachments have been provided. These consist of baseplates with either mechanical anchorage into a concrete roof slab or through-bolts to spreader angles or sandwich plates on the underside of the existing roof deck. In the latter case, the spreader angles or sandwich plates are enlarged to activate multiple deck flutes to resist the load.

Tieback anchors exist in three different locations: the OPC connector, Building 3, and Building 28.

Post-style tieback anchors were used for the OPC connector and Building 3 and were connected to steel or concrete framing respectively. However, a proprietary system was required for the sloped, light-framed roof construction at Building 28, and appropriate backing was specified to accommodate the tieback loads.

Calculations guardrail, ladder, and tieback anchor connections are included in Appendix A.

Note:

KEE SAFETY can provide general guidance on the use of the fittings detailed in this catalog. However, the nature of the product means that the ultimate responsi-bility for selecting the correct fitting for an application rests with the customer.

The customer should also ensure that any existing structure to which a KEE

SAFETY component is being secured is of sufficient strength to support both the weight of the KEE SAFETY construction and the imposed loads applied, including wind loads, snow loads, and any other superimposed loads.

TÜV Approval KEE SAFETY components are approved by TÜV, Eu-rope’s leading indepen-dent testing house. The maximum load of each fitting type is as stated on the TÜV Certificate, a copy of which is available upon request. For an up-to-date TÜV listing see our website at www.keesafety.com.

Selecting Kee Safety Components Every fitting is illustrated and accompanied by a table of sizes and weights. Each fit-ting has a simple numerical code reference, which is unique and differentiates it from every other fitting. The code defines the type of fitting and the pipe size or sizes it is designed to receive.

Three Socket Tee Most commonly used as the 90° joint between the top rail and an intermediate upright on safety railing. As there are two socket screws in the sleeve, this fitting can be used where a join is required in the horizontal pipe. The Type 10 fitting can be used as an alternative when a join in the pipe is not required.

Kee Klamp®

Engineering The engineering principle behind the KEE KLAMP component is the foundation of the most versatile pipe connection system available. We provide the versatility needed to achieve virtually any structure configuration.

KEE KLAMP fittings are iron castings manufactured to the requirements of ASTM A47-77- 32510. We have engineered a range of components to suit eight different sizes of pipe.

Hexagon set screws firmly lock the component to the pipe. Set screws are manufactured in case hardened steel and are protected against corrosion with our unique protectant called

KEE KOAT.

A KEE KLAMP component (size 5 to 9) can support an axial load of 2000 lbs. per set screw with the set screw tightened to a torque of 29 lbs./ft. (rating includes a safety factor of 2:1). This is normally obtained when the set screw is fully tightened using a ratchet wrench.

Galvanized Steel Components Steel pipe is an inherently efficient structural component. It is strong, has no sharp cor-ners, and is readily available worldwide. The difficulty in using steel pipe to form struc-tures arises when joining. Threaded pipe must be supplied in set lengths making for zero flexibility in installation. Welding is labor intensive, requires a highly skilled workforce, and specialized equipment.

The answer is KEE KLAMP components. The underlying principle is simple but highly ef-fective: use slip-on components to create versatile and rigid tubular structures. The KEE KLAMP principle has been developed and refined for more than 75 years resulting in an extensive range of components suited for any need.

Swivel Fittings Types F50, M50, MH50, M51, MH51, M52, and M58 are known as swivel fittings and can be assembled as Types C50, CH50, C51, C52, and C58 or supplied as separate items. They are frequently used for bracing but can also overcome problems where joints are required at angles other than those achieved by fixed angle fittings. For economical use of pipe, when making 'C' fittings, or combination fittings, Types

F50 (sizes 5-9 only) can be combined with different sizes of Types M50, MH50, M51, MH51, M52, and M58. F50-4 and M50-4 will only combine with each other.

WARNING: An entire structure should not be constructed from swivel fittings, as they would not provide sufficient stability or rigidity in the structure. Types M50, MH50, M51, M52 and M58 can also be used separately to secure various types of in-fill panel. These fittings are not designed to take bending moments.
