Z type sheet pile FSP Z-25 FSP Z-32 and framing of members for FSP Z-38 railings of all FSP Z-45 types shall be of such construction that the completed structure shall be capable of withstanding a load of at least 200 pounds applied in any direction at any point on the top rail, with a minimum of deflection. The Sea-Tac International Airport is a complex operating facility which is governed by a very FSP Z-25 strict set of operating rules to insure the safety of the traveling public, the operators of the various airlines and those individuals who function as support personnel to the facility.Alternative materials for the marina were considered by the owners and the project superintendent. Winter-time construction would not be practical using a cast-in-place concrete system. It is recognized FSP Z-32 and understood that the Contractor is required to comply with the most current edition requirements contained in FAA Advisory Circulars and Port of Seattle Rules and Regulations as they pertain to this project.

Straight web-type sheet pile from YSP F employees or YSP FA material handling shall be YSP FX provided additional strength by the use of heavier stock, closer spacing of posts, bracing, or by other means. With a cast-in-place concrete design, pumping and shoring formwork would be required as well as protective tenting and heat to protect the concrete during coldweather curing. Other types, sizes, and FSP Z-38 arrangements of railing construction are acceptable, provided they meet the following conditions.More importantly, heavy ready-mixed concrete trucks FSP Z-45 were not permitted to travel on the local roads during the winter due to the damage they might cause during seasonal freeze-thaw cycles. A smooth surfaced top rail at a height between 39 inches and 45 inches above floor, platform, runway, or ramp level. It is understood and accepted by the Port of Seattle that the Contractor has familiarized itself with general Airport operations and has taken these into consideration in arriving at its bid prices and in scheduling its various activities.

Martin knew that precast concrete could be erected during cold weather and could be fabricated to look like natural stone in retaining wall and breakwater systems.Strength to withstand at least the minimum requirement of 200 pounds top rail pressure with a minimum of deflection. Not only would YSP F precast concrete be more versatile for the site conditions, but the cost of precast was equivalent to a cast-in-place alternative, because precast did not require laborintensive shoring and formwork construction. Protection between top rail and floor, platform, runway, ramp, or YSP FA stair treads equivalent at least to that afforded by a standard intermediate rail. iv. Elimination of overhanging rail ends unless such overhang does not constitute a hazard.The selection of precast architectural and YSP FX finish designs would also meet the owners' demands for an aesthetically pleasing facility.
