Be Cool and don’t take a beating !! Our elegant Concrete Water Fountains will easily survive mischievous children, rowdy teenagers, reckless visitors and punk vandals. They are designed to withstand these battles and to last many years – providing year-round beauty with minimum maintenance. They are built of steel reinforced precast concrete using the highest quality cement, aggregates (stones) and sand. They meet or exceed all industry standards for durability and strength. In addition they are available in a variety of attractive earth-tone colors that will blend well with our other site amenities such as picnic tables, benches and trash receptacles. They will enhance the attractiveness of any outdoor or indoor facility.

Our Concrete Water Fountains are popular for both indoor and outdoor locations. They provide a clean, filtered, chilled drink of water. Our fountains are in use all over the country and can be found at pools, schools, campuses, parks, patios, campsites, sports arenas, tennis courts, basketball courts, baseball fields, indoor and outdoor malls, plazas, offices, theaters and public gardens.

Our Concrete Water Fountains offer maximum strength and durability with minimum maintenance. They are vandal resistant and they have a rustic elegance that blends beautifully in outdoor and indoor environments. In addition, they are completely lead-free and the internal parts, such as the brass bubblers, are corrosion free. And the flow regulators are easy to adjust so that the water stream stays in the bowl. Finally, there are numerous models available to meet any user need.

Today’s water drinking fountain is the result of over 100 years of development. The first water fountains available to the public were developed in the early 1900s by Halsey Willard Taylor and Luther Haws. They were motivated to provide a safe and sanitary drink of water to the public in large part because of the death of Halsey W. Taylor’s father from contaminated water. As the water fountain became more common in the lives of the people there was a demand for chilled water. This led first to ice-cooled water fountains and then ammonia refrigerated water fountains. Later in the 1950s, wall-mounted water fountains were developed for use in public schools, hospitals and other buildings with high traffic. In the 1960s the industry recognized that physically challenged people had difficulty obtaining a drink of water from water fountains. Therefore, laws and designs changed to make water fountains accessible to all people. Additional developments were made to offer a drink of water as contamination-free as possible. Efforts were made to eliminate all lead and other metal contaminates from the water.

All of our concrete water fountains meet the federal regulations established by the Americans with Disabilities Act (ADA). They meet state and federalhandicapped requirements when installed in accordance with the clearances defined by the ADA. In addition our concrete water fountains are considered “lead free” as determined by all known definitions including ANSI/NSF Standard 61, Section 9, California Proposition 65 and the Federal Safe Drinking Water Act. Our concrete water fountains are accessible for the handicap. There is plenty of knee clearance for people in wheelchairs and an easy front push button. There are a number of available options such as concrete or chrome bowls, side faucet, freeze proof valve and tamper resistant concrete bubbler guard. In addition these fountains include a drain tail piece and bubbler valve for plumbing connections. The design of the access panel makes installation easier for the buyer.

Our concrete water fountains are not only weatherproof, vandalism resistant and handicap accessible, but they are also available in several designs including pedestal mount, barrier-free pedestal and wall mount. Our color choices will allow a complimentary match with any décor. And all of our water fountains are manufactured with lead-free materials and components.

This paper describes the arch design process, which included both two and three dimensional finite-element analysis for the arch cross section design, and to check the effect of differential longitudinal loading and foundation conditions. The effect of many alternative ground improvement options was considered, in order to optimise the foundation design. The final design was developed after the award of the contract and used three different options, depending on the ground and weather conditions at the time of construction. The following information is presented in the paper:

• Comparison of bending moments and forces in the adopted arch profile with alternative profiles.
• Comparison of foundation bending moments and forces for different raft cross-sections and foundation treatments.
• Comparison of alternative analysis methods for the raft foundations
• Comparison of settlement analysis results with analyses carried out by the project primary designers (SMEC Australia).

PennDOT had a challenge on their hands, as they attempted to balance three key fac-tors while trying to figure out which alternative was the best solution for the cost. They wanted to match the shape of the existing culvert they were tying into, minimize the impacts to the surrounding community, as well as accommo-date the numerous existing pipelines that have been added to the culvert throughout the years.

After examining various alternatives, engi-neers at PennDOT and Oldcastle Precast, Inc. developed a simple solution to the problem while allowing for a quick installation. PennDOT elected to use a 48-inch x76-inch horizontal el-liptical reinforced concrete pipe (HERCP) with flared end sections on both sides of the roadway in lieu of a precast box culvert or other meods. This would allow for a four to six week con-struction schedule and the best product for the money spent. HRI, Inc. of Bloomsburg, PA was selected by PennDOT to complete the proj-ect and Oldcastle of Farmingdale, NJ provided the elliptical pipeline and flared end sections.

Eleven existing pipelines (five pipelines on the northbound side and six on the southbound side) of various sizes and types had been tied into the existing culvert at various times, providing a chal-lenge for construction. These pipes ranged in size and material from 8-inch diameter ductile iron to 18-inch diameter reinforced concrete, and were aligned at different inverts and angles. The exact tie-in location of these lines needed to be deter-mined, so a laying schedule was developed. Each pipe could then be numbered and pre-cut holes positioned to allow for the existing lines to simply be mortared into place. The pipe was assembled by Oldcastle prior to shipment to ensure the ac-curacy of the hole placement and joint al

TechSpan® is the most reliable, cost-effective precast concrete arch system available for the construction or replacement of culverts and bridges.

Advanced design procedures and unique fabrication capabilities provide the most efficient use of concrete and reinforcing steel. Unlike most alternative systems, efficiency and economy of design increase progressively as the embankment height over the crest increases. Construction of TechSpan is simple, rapid and predictable with small crews and conventional equipment.
