President's Corner

As we all are winding up the back end of summer, I hope everyone has seen the increase in communication efforts by NAXSA. The updated newsletter schedule, the additional informational Zingers being distributed, the new industry directory project and the new membership campaign have all been rolled out since our meeting in Phoenix this year. All of us at the committee, officer and staff levels are working hard to make sure the members of NAXSA can see this young and exciting organization has found its voice and our organization is delivering real value to its members.

As has been stated before, NAXSA is a volunteer organization whose mission is to represent the trench safety dealers, vendors, rental house’s and engineering members that all are a part of our industry. The association is looking for additional volunteers to get involved in NAXSA to lend their talents, voices and ideas to help direct and drive this association as it further matures. I respectfully ask that each of you consider volunteering for a committee position or get involved in any area where you think you might make a contribution. This your association and we need new ideas, input and talent in so many areas.

As you may have seen, the new NAXSA Member Directory & Buyers Guide project has been rolled out and everyone is excited to see the final product. This new directory will hopefully list all the companies in our industry and also list the many vendors that focus on and support our industry. Please make sure you get your listing information back to the NAXSA office as soon as you can. We want to have as accurate directory as we can for the first pass.

The new OSHA/NAXSA alliance in Denver is doing fantastic. Thanks to the many volunteers that have jumped in to help organize, setup, advertise and hold this new training class with OSHA. It appears this is going to be an industry first in regards to a “hands on - in the ground” training program. If this event comes off as planned, we suspect additional training programs like this one in Denver will be rolled out quickly across the nation. This training program is something many in our industry have been wanting for years. I hope each of you can get up to speed on what is happening in Denver and if possible, we would love to see you join in and participate.

As we approach the fall months, I wish everyone a very safe, prosperous and successful fourth quarter.

Ron Chilton, NAXSA President

Veteran West Michigan demolition contractor happy to discover ‘new’ Slide Rail shoring system for soil remediation project

by James McRay

Recently, Pitsch Companies were low bidder on a Michigan DEQ-let demolition and soil remediation project in Grant, Michigan. Pitsch was tasked with demolishing an old gas station, plus the removal and replacement of approximately 2,700 cubic feet of contaminated soil under the old Mini-Mart.

A project like this would normally be old hat for the veteran demolition company, except for a key element to the soil remediation portion: the contract stipulated that a Slide Rail System had to be used to shore the approximately 40 x 40 x 20 feet deep excavation. For the project, the Slide Rail System was manufactured and directly-rented by NAXSA member Efficiency Production.

“It wasn’t an issue of never having used Slide Rail before,” said Steve Pitsch, President of Pitsch Companies. “It was that this was the first time I’d ever heard of something called a Slide Rail System, and we’ve been in business for 60 years.”

Slide Rail System perfect match for soil remediation requirements
Slide Rail is a component shoring system comprised of steel panels—similar to trench shield sidewalls—and vertical steel posts. Slide Rail is installed by sliding the panels into integrated rails on the posts then pushing the panels and posts incrementally down to grade as the pit is dug; a process commonly referred to as a “dig and push” shoring system.

“One of the important advantages of a Slide Rail System over open-cutting is that there’s no over-digging; the excavation walls can be cut exactly vertical,” explained Tim Hurst, Head of Efficiency Production’s Special Operations Shoring Division. “This was a critical factor in the soil remediation, as the system keeps constant pressure against the surrounding dirt, allowing the exact amount of removal and replacement of the contaminated soil,” Hurst said.

“The ‘positive’ shoring system also creates a much tighter work area,” added Hurst, “which was very helpful working in Grant’s historic downtown area.”

Efficiency Production Slide Rail System required shoring system
It is unusual, but not unheard of, for a shoring system to be stipulated in a state-let project contract. However, the engineers at Superior Environmental, the environmental management company overseeing the soil remediation portion of the demolition, had good reasons to do so.

“Efficiency Production assisted throughout the entire design, development, and installation of the shoring system,” said Superior’s Project Engineer, Corey Buckner. “Even before we bid the project, (Retired Division Director) Greg Ross talked us through the shoring process and how Slide Rail would work,” Buckner continued. “We relied on Efficiency’s ‘Special Ops’ team to examine the plans, and provide the engineering and design for the shoring on this project,” said Buckner.

“I felt Greg and his team had given us so much support upfront, that it only seemed fair to add Efficiency as a propriety line item for shoring equipment in the bid,” explained Buckner.

Slide Rail System installed twice
Pitsch actually installed the 20 x40 foot two-bay Multi-Bay™ configured Slide Rail System two times. They excavated and installed the shoring system to grade, replaced the contaminated soil with clean sand, then completely removed all the Slide Rail components before moving sideways 20 feet and repeating the whole process again with the same Slide Rail equipment.

“Coming from an outside industry, I found the Slide Rail System very easy to use,” said Pitsch. “Once we were awarded the project, I really started looking forward to it. It was fun to learn,” he added. “Even after 60 years, it’s exciting to be exposed to something new.”

Slide Rail is installed by sliding steel panels—similar to trench shield sidewalls— into integrated rails on vertical steel posts then pushing the panels and posts incrementally down to grade as the pit is dug; a process commonly referred to as a “dig and push” shoring system.

The “positive” shoring system also creates a much tighter work area, which was very helpful working in Grant’s historic downtown area.

Slide Rail keeps constant pressure against the surrounding dirt, allowing the exact amount of removal and replacement of the contaminated soil; a critical factor in the soil remediation portion of the project.

Using a Volvo EC460-B excavator, a Cat 230D excavator, a Cat 950 rubber-tire loader, and a Cat 226 skid steer; Pitsch was able to install and remove the Slide Rail System—twice—in about five or six days.

A Closer look at Site Specific Shoring Plans

by Joe Turner, PE

Site specific shoring plans are originated in response to OSHA Subpart P-1926.652(c) (4) Option 4, Design by an Engineer. In the standard OSHA states:

  • 1926.652(c)(4)(i)- Support systems, shield systems, and other protective systems not utilizing Option 1, Option 2 or Option 3, above, shall be approved by a registered professional engineer.
  • 1926.652(c)(4)(ii)-Designs shall be in written form and shall include the following:
  • 1926.652(c)(4)(ii)(A)-A plan indicating the sizes, types, and configurations of the materials to be used in the protective system; and
  • 1926.652(c)(4)(ii)(B)-The identity of the registered professional engineer approving the design.

However, it does not go into great detail about what it should look like or contain. In practice the plan serves the needs of many different people that can become involved with the engineered shoring plan. The contractor, his workers, OSHA, the reviewing engineer and the lawyer all look for different things in the plan. This article looks at the site specific engineered shoring plan, what it should contain and the reasons why.

When and Why to Use a Site Specific Plan
Site specific plans are required when there is no tabulated data available for the shoring system that the contractor wants to use. These cases are usually where;

  • Tabulated data shoring systems like hydraulic shores and shoring shields are being used in situations that are not described or allowed by the data.  The site specific plan is not used to get around the tab data but simply to use the equipment in ways that are not envisioned by the data. For example shoring shields with end plates are not allowed by tab data but it is still perfectly safe to do it as long as the loads are calculated and do not exceed the allowable strength of a shield or the plates.

Another example is where single vertical lines of hydraulic shores are used in conjunction with shields at utility crossings.

  • With tabulated data the soils must always first be identified by the competent person in accordance with OSHA Appendix A. The OSHA soil types and loadings are very conservative compared to engineered soils analysis so there is a lot to be gained in depth and shore spacing using engineering calculations.
  • Shoring systems like sheet pile and wale typically are a combination of steel shapes and are not designed and marketed as a shoring system. There is tabulated design data for the components but it still requires an engineer to design the system.
  • Manufactured systems like slide-rail and hydraulic brace are complicated and are best done by an engineer or at least someone that has experience with the data and engineering technical knowledge.

Sometimes the contractor uses engineered plans for risk management. Just to make sure his guys are getting it right and have someone outside to share the responsibility if they get it wrong. In some cases the engineer just determines the soil types so that it is not all the responsibility of his competent person. The essential difference between Option 4 and Options 1 and 2 is that an engineer is responsible for the shoring design, not the contractor. The contractor is still responsible for installing it safely and in accordance with the plan.

Another difference between site specific plans and tabulated data is that the plan looks at the specific location. It takes into consideration existing structures and buried facilities that affect the shoring system and looks at temporary surcharge loads. The site specific plan should clearly designate the location of all buried  utilities and if they are close or interfere with the shoring system there should be notes that require their exact location prior to or during the shoring installation. Critical facilities like high pressure gas and buried electrical lines should be clear on the plan.  Problems that would delay the work in the field should be rooted out and solved at this stage of planning.  This is part of what the contractor is paying for when he orders an engineered plan, the engineer’s eyes on everything that affects the safety and efficiency of his shoring operation. The contractor and the reviewing engineer should not let one of these plans go through unless this information is there.
