Fortis Pile Shoring Design
Tall Soldier Piling with NO TIEBACKS
Artimus Hotel,
Tiebacks can complicate projects
The traditional soldier pile shoring design has some drawbacks when the excavation/shoring heights raise above 12 feet:
-
The soldier pile wide flange beam section become large and expensive to purchase and handle
-
Tieback anchors are the most commonly used solution to this problem, however, frequently tieback anchors intrude on neighboring properties and obtaining easements can be difficult if obtainable at all
-
The alternative to to use walers, struts and/or raker beams, however working around these is costly.
Fortis Pile Shoring Design
Use of Fortis Pile Shoring in many cases can help to avoid the issues stated above:
-
No tiebacks
-
No struts
-
No raker beams
-
No easements needed
As can be seen in the photos & drawings below, Fortis Pile Shoring can eliminate many of the complications that tall soldier pile shoring projects have.
Site Title
Site Plan View – Tieback & Strutted Shoring:
Shown is a plan view of a typical shoring site where tiebacks are required on three sides and struts are required on one side. (The owner could not secure an easement for tieback anchors on the east wall.) Shown here are three properties which require easement agreements. The cost of easements can run anywhere from $ 5,000 to over $ 50,000 for each of these three easements. The west wall requires tiebacks which penetrate under the roadway. This required both City approval and the approval of the Utilities buried in the roadway. Because of the utilities, the City hired an outside engineering firm to oversee the tieback design and installation, for which the developer was billed. The costs associated with the use of struts within the shoring are more difficult to quantify. Working around struts is expensive and time consuming for the building contractor.
Site Plan View – Fortis Pile Shoring:
Here the use of the Fortis Pile shoring system eliminated the need for tieback anchors and struts. Therefore easements were not needed, nor were approvals from the City for the installation of tieback anchors under the road and close to buried Utilities.
