2 Aout The O-Pile Alliance is a rapidly expandg construction method that utilize pipe to pipe walls with welded-on connectors to form extremely strong foundations, arriers and retag walls a cost-effective way. O-Pile is the authorized partner to offer these pipe to pipe systems. WOM/WOF XL ~3.6 ~3.5 The goal of O-Pile, as the authorized partner of projects, is to estalish franchises gloal markets via local pipe plants wherey 75% of steel wall systems are sourced locally and the Recently, there has een a huge crease the use of systems on construction projects around the world, particularly with ports, retag walls, and deep foundations, as well as on a variety of other large- and small-scale projects. systems offer a stronger, more efficient, cost-effective alternative to high modulus walls that use eams and heavy Z- or U-type sheet piles. ~ 0.4 (6mm) weld ~0 alance is provided y the O-Pile partners. ~0.5 (1mm) ~0 There are only a handful of countries the world where Flat, Z- and U-shaped steel piles are manufactured, whereas pipe factories are aundant worldwide. Therefore, a construction project usg Pipe Sheet Pile will almost always utilize over 75% locally produced pipe, therey avoidg the aritrary expense of costly importation fees. Either new or used steel pipes are aundant, low cost and easy to manufacture, so they offer a much more economical solution for large-scale construction projects when compared to traditional concrete or steel sheet pile alternatives. With utilizg WOM and WOF terlock connectors, the design engeer, through the O-Pile alliance of partners, is ale to utilize readily-availale, locally-produced pipes to provide practical, cost-effective solutions. WOM/WOF XXL ~ 0.4 (6mm) weld ~ 6 ~ 5.8 ~0.5 (1mm) ~11.8 ~0 ~0 O-Pile partners will utilize local pipe makg capaility to offer a far greater range of wall sizes, shapes, and load-earg capacities than alternative options and one that can e dialed to meet the specific specification needs for any project. For your systems, turn to O-Pile to get the jo done right. 4 o-pile.com o-pile.com 5

3 Technical Advantages These are the four technical reasons why engeers and designers now consider the system to e superior to other sheet pile or concrete options: 1. Efficiency: Kg pile systems usg products like HZM or PSp crease weight learly as strength is creased, ecause there is little change panelwidth to offset the creasg weight as section size is creased. However, a pipe-to pipe system of a given wall thickness has almost negligile weight crease with ga strength ecause strength ga is achieved y creasg diameter and not y simply usg a heavier section... Capacity: The vertical load-earg capacity of Pipe Sheet Pile is significantly higher than standard U- or Z-type sheet piles or comed wall systems of similar weight. 3. Connections: Previous attempts at pipe to pipe were ased on usg some comation of angle and T or CHS and T connections that often proved difficult to weld, were prone to de-clutchg hard drivg, and also required groutg. 4. Surcharge: forms extremely effective and strong retag walls for structures such as mare erths and highway or rail grade separation. They can also e effectively used ridge autments or as permanent walls of elow grade parkg structures. section modulus: ³/ft vs Comed Wall Systems The troduction of the WOM/WOF connectors, designed specifically to resist high tension and rotational forces to O-Pile HZM or PSp s are just pla stronger, any way you look at it. more than 3400 kn/m, provid the user with a low-cost, high-capacity connection they did not have efore panel weight: l/ft O ".5" Comparison No. 1 Typical system HZ 880M C-4 + AZ /ft 167 ³/ft 47 l/ft² 54 l/ft² O ".65" Comparison No. Typical system 306 ³/ft 11 ³/ft 59 l/ft² 6 l/ft² PSp 1117 (103) + PZ61 O Comparison No. 3 Typical system HZ 1180M D-4 + AZ ³/ft 356 ³/ft 65 l/ft² 91 l/ft² 6 o-pile.com o-pile.com 7 7

5 Installg Pile Sheet Pile Drivg is much easier to drive than is often thought: A simple panel is used for pipe alignment; and viratory hammers, impact hammers and even press- methods can e used to rg the piles to grade. Drivg ostacles can often e removed from side the pipes y excavation, drillg, or jettg, without disturg the environment. Usually, strict noise aatement standards can e easily met, even for uran settgs. Waterproofg If your project volves cofferdams, de-waterg, tunnels, cutoff walls for site If your project volves cofferdams, de waterg, tunnels, cutoff walls for site remediation, or any application where water leakage presents a challenge, then sealed is an excellent solution. WADIT, a gloally-proven sheet pilg terlock sealant, is highly effective terlocks and can meet the most challengg waterproofg needs. WOM/WOF connectors can e supplied already filled with WADIT, ready to e delivered to the pipe manufacturer, or to the jo site, for weldg onto the pipe piles. (The length from terlock to stem of the WOM/WOF ensures that the sealant is not affected y heat generated from weldg.) Applyg WADIT a factory environment is preferred, as it elimates site preparation and application, and it speeds up construction. WADIT sealant, used conjunction with and connectors, is creasgly the go-to solution for engeers and designers lookg for an effective waterproofg option that is strong, economical, safe and convenient, safe and convenient. WADIT = Watertight Simply put, Pipe Sheet Pile can e driven quietly and effectively with a wide range of equipment WADIT can e used every possile environment (from tropical to arctic) and is particularly effective mare conditions. 10 o-pile.com o-pile.com 11

6 Duraility How well does stand up to corrosion? Along with their enormous strength-to weight ratio and overall cost-effectiveness, has a distct advantage over traditional steel sheet piles and that s their superior duraility to other steel wall geometries. Superior Geometry for Duraility: cuts costs with its easier application of corrosion protection, and y havg a mimized exposed surface relative to other kg pile shapes. Additionally, the terior of the pipe can e sealed off (capped or filled) from oxygen filtration order to avoid side corrosion. And, concrete can e poured side the itself, thus further creasg strength while also preventg oxidation or corrosion on the terior surface. With any or all of these techniques, has only the exterior face exposed to corrosion, contrast to a traditional eam, which has all of its surfaces exposed to corrosive elements. Pipe sheet pile that are used corrosive soil and/or water need only have a corrosion allowance factored for the exterior surface of the pile. Standard Comed Wall Systems Optimizg Duraility with Sacrificial Thickness: Sacrificial thickness is the numer one choice for designers who need to meet design life criteria. Usually, additional steel is applied to the entire exposed structure, when it is actually only required on the most corrosion-vulnerale surfaces: the splash and low-water zones. Why not just use a different grade of steel? Solutions utilizg steel grade compositions either work for the splash zone or the low-water zone, ut not for oth. Therefore, additional measures are often needed, such as coatgs or cathodic protection, which can lead to additional expense and complication. With, an optimal solution with targeted design life can e otaed without special steel grades, additional coatg, or wasted extra steel. Thicker pipe used aove the seaed spliced to thner pipe elow allows the designer to target sacrificial thickness exactly where it is needed. With the small production tolerances of pipes, can e easily spliced, matag consistent external diameter and variale ner diameter as necessary for sacrificial thickness. This gives the most efficient use of steel and the most cost-effective solution for duraility. The location of the splice is usually aove the seaed where pile stresses are low.
