2 Custom Shoring Services That Help You Get the Job, and Get the Job Done! President s Message: With the challenges of being in business continuously on the rise, business owners and their key managers are looking for help wherever and whenever they can get it. As companies expand and grow, it can be difficult to find experienced personnel to keep pace with that growth, especially in specialized areas such as shoring for excavations and trenches. Efficiency Production, Inc. has recognized this need and provides a full range of construction shoring services that fill this gap. We have teamed up and worked closely with a large number of our customers and have time and time again successfully assisted them in selecting standard, special, or custom designed and engineered products to handle their special shoring requirements. Whether it means providing you with CAD drawings and illustrations to help in the bidding or approval process, building a standard or custom designed and engineered product, or providing onsite installation assistance and training; Efficiency takes great pride in helping you get the job, and getting the job done. Looking forward to working with you, -Ken Forsberg, President Efficiency Production, Inc. fter calling Efficiency, I talked at length with Atheir Slide Rail Installer, and he sent me initial information, manuals, videos, and a proposal drawing; really everything I needed to bid on the project. He even came out to the job site to look at the conditions. We were competing for the job against one other contractor who came in with no other shoring options other than open-cut, so I think the Slide Rail option helped us land the job. -Randy McKenney, Goodfellow Construction, Corunna, Ontario hadn t used Slide Rail before, but with the I prospect of using it again, we can bid on more pump station or lift station jobs. Efficiency s Slide Rail potentially opens up another avenue for our business. -Joe Raica, Joe Raica Excavating, Fowlerville, Michigan Helping You Get the Job... Custom Engineering...

4 How to Size a Trench Shield Soil Classifications, Calculating Depth Ratings, and Sizing a Shield How to Size a Trench Box Depth of cut* Soil conditions* Type A (25#) Type B (45#) Type C-60 (60#) Type C-80 (80#) Hydrostatic * see depth certification chart Outside Pipe Diameter (Shield must be a minimum of 12 in. wider than the pipe.) Pipe Length (Shield must be 2 to 4 ft. longer than the pipe.) Bucket Width (Inside shield: 12 in. less than shield.) Machine Lift Capacity (1.5 times shield weight at 20 degree radius.) The following will explain how to determine the specifications listed above. How to determine the depth of cut: Slope must start 18 in. or 1½ ft. below the top of the Shield How to determine the width of a trench shield: Trench Shield width determined by Outside Diameter (OD) of the pipe or the OD of the excavator bucket Allow 6 in. of clearance on each side of pipe bell Shield should be a minimum of 12 in. wider than the excavator bucket OD How to determine the length of a trench shield: Inside length clearance of pipe is approximately 2 ft. less than the overall length of the shield Shield must be 2 to 4 ft. longer than the pipe How to determine the machine lift capacity: Lift capacity is 1.5 times the shield weight at 20 ft. radius at grade Calculating Depth Ratings: PSF ratings and depths are based on temporary loading. Lateral pressure per foot of depth: Type A Soil = 25 lbs. Type B Soil = 45 lbs. Type C-60 Soil = 60 lbs. Type C-80 Soil = 80 lbs. Depth rating using shield capacity (e.g lbs.): 1200 / 25 = 48 ft / 45 = 27 ft / 60 = 20 ft / 80 = 15 ft. Soil Definitions: Apparent cohesion Cemented soil Layered soil Plastic Saturated soil Submerged soil No soil is Type A if: It is fissured It is subject to vibration It has been previously disturbed It is part of a sloped, layered system which dips into the excavation on a slope of four horizontal to one vertical [4H:1V] or greater It is subject to other factors requiring classification as less stable Type B Soil: Cohesive soil with unconfined compressive strength greater than 0.5 tons per square foot (tsf). but less than 1.5 tsf. Granular cohesion-less soils, e.g., gravel, silt, silt loam, sandy loam Type A fissured or subject to vibration Unstable dry rock It is part of a sloped, layered system which dips into the excavation on a slope less steep than 4H:1V, but only if the material would otherwise be classified as Type B Type C Soil: Cohesive/non-cohesive soils with unconfined compressive strength of 0.5 tsf or less Granular soils including gravel, sand, and loamy sand Submerged soil or soil from which water is freely seeping Submerged rock that is not stable Sloped, layered system which slopes into an excavation at an angle of 4H:1V, or steeper 4 Trench Shielding Product Guide & Services

5 Options & Accessories Versatile and Innovative Options and Accessories Foam Filler Foam Filler is made of lightweight polystyrene that fills double wall cavities minimizing mud and sand build-up inside of the walls. Pushing Blocks A set of four pushing blocks, each made of 1 in. thick steel, are used for pushing the shield to grade. Pushing Blocks are NOT intended for pounding with excavator bucket. Pulling Lugs A set of two pulling lugs are welded to the front end of the sidewalls to pull the shield easily along the trench as the job progresses. Stacking Pockets Stacked shields are connected using pins placed through welded stacking pockets. Pockets allow for shields of varying sidewall widths to be stacked. Fast Stak Fast Stak brackets allow shields to be stacked, and quickly and easily secured. The brackets are attached to the sidewalls or spreaders depending on the chosen design. Stack Brackets Stack Brackets are perfect for securing stacked four-sided shields or other configurations where stacking pockets or Fast Stack can not be utilized. The brackets are secured on the trench box sidewall s lifting lugs. 5

6 Options & Accessories Versatile and Innovative Options and Accessories Corner Brackets A set of four corner brackets (patent pending) allow for the construction of four-sided shields using standard trench shield sidewalls. EC Brackets End Panel Connector (EC) brackets are a quick and easy way to add three or four-sided protection to any trench shield. EC brackets secure to the adjoining sidewall s spreader collars. Mud Plate The mud plate offers excellent protection against water, mud, and sand encroachment for workers in the front of the shield. (Refer to mud plate, page 12) Extended Collars Heavy Duty Collars Custom Spreader Location Custom designed and constructed shields include the option for jobspecific spreader collar placement. Spreader Collar Options Efficiency offers a variety of options for trench shield spreader collars, including extended collars and heavy duty collars. Collar Repair Kits are also available for all collar sizes.

7 Options & Accessories Versatile and Innovative Options and Accessories Arches A wide variety of arch assemblies are available for all types of pipe installation such as box culverts or large diameter pipe. Arches are an excellent accessory for boring applications. (Refer to Arches, page 23) Shield Grabber Shield Grabber is designed to be picked up with the hook of an excavator bucket. A guide rail enables the operator to position the lifting bars under the lifting hooks on the shield, easily handling the shield in and out of the trench. Octagon Box Octagon Boxes offer four-sided protection with a tremendous strength to weight ratio. Octagon Boxes are rated for deep excavations but are lightweight enough to handle with light-duty equipment. (Shown with optional custom color.) Pipe Puller The Pipe Puller is an efficient method of joining large diameter pipe and box culverts. The Pipe Puller remains stationary in the first pipe while a 100 ft. cable is extended and secured to the last pipe, then activated to join the sections. (Refer to Pipe Puller, page 40) Hi-Hopper The Hi-Hopper bedding material dispenser is available in Standard or Heavy Duty models up to 4 cu. yd. capacities. Hi-Hoppers hold bedding material in the hopper for controlled discharge directly into the excavation. (Refer to Hi-Hopper, page 39) Material Separator Material Separators are designed to separate large stones and other debris from existing backfill material. Screens are constructed of heavy-duty vertically placed bars and are available in 3, 4, and 6 in. widths. (Refer to Material Separator, page 39) 7

8 Features Innovative Features that Increase Job Productivity High Strength Mill Certified Steel All structural steel is fully tested and certified to be high strength, providing maximum depth to weight ratios. P.E. Certification Tag (Tab Data) Every trench shield includes a certification tag which is permanently welded to the trench box sidewall. The certification tag includes the corresponding serial number for the trench shield and lists the shield s tabulated data including depth ratings. Double Tube Top Rail Steel reinforced double tube top rails are standard on HT6, HT8, and PXL trench shields. Adjustable & Stackable Shields are designed to stack on flat edges for deeper excavation projects. A wide variety of spreaders are available ranging in width from 2 ft. to 20 ft., allowing shields to be adjusted for each project. Plug Welding on Double-Wall Shield Inside skin plates on double-wall shields have the most plug welds in the industry.

26 Slide Rail System Universal Component Steel Trench Shielding System What is Slide Rail? Efficiency Production s Slide Rail is a component system comprised of steel panels and posts. It is commonly used as a cost-effective alternative to traditional driven close-sheeting. The universal system can be used in a variety of configurations to meet any shoring challenge, particularly in poor soil conditions or near adjacent structures. Where is Slide Rail Used? Efficiency s Slide Rail can be custom-engineered to shore: Large and small vault installations Pump stations, lift stations, and wet-wells Large tanks Footings and foundations Press pits inside buildings Long pipe joints Parallel water-mains Boring operations How is Slide Rail used? Slide Rail is installed simultaneously as the trench or pit is excavated by sliding the panels into rails on the posts, and 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 system. Slide Rail posts have either a double or triple rail which telescope panels to required depth. Standard 4-Sided Pit Individual Slide Rail components offer the option of using lighter equipment when installing the system. The cost of rental and installation of the system is approximately 50 percent of steel sheeting. Installation and required excavation are completed together, saving time and reducing cost. Wall to wall working space is greater. Minimal vibration to adjacent buildings and surrounding structures. ClearSpan System The Efficiency ClearSpan System incorporates special walers for larger unobstructed four-sided working pits for site specific jobs. Provides a large unobstructed working area. Cost effective compared to steel sheeting and other methods. Heavy duty panels provide minimal deflection. Minimal vibration to adjacent buildings and surrounding structures. Linear or 4-Sided Multi-Bay This configuration is ideal when installing next to existing utilities and structures. Longer pipe may be installed by raising or removing the parallel beam spreader assembly. Innovative parallel beams eliminate post deflection during installation and removal. The roller design facilitates the vertical movement of the integrated beam and spreader unit. The parallel beam can be used with spreaders or arches. 4-Sided 4-Sided Pit ClearSpan Linear Multi-bay 26 Trench Shielding Product Guide & Services

40 PP Advantages: Pipe Puller Laser-Friendly Pipe Installation Convenient - The Pipe Puller remains stationary in the first pipe until the cables are extended to their full length of 100 ft. This saves the time and energy of moving the pipe puller each time a new pipe is laid. Frees Excavator To Dig Ahead - Your excavator digs ahead while the Pipe Puller firmly joins several pipe sections, which minimizes grouting. Reduces Pipe Breakage - Minimizes pipe breakage with a more secure method of joining pipe sections. Easy, One-Person Operation - The Pipe Puller s 32 ft. control cable allows for operation from a safe distance outside the pipe. Includes a 1,200 lbs. winch. Add additional snatchboxes for greater capacity. Anchor Legs Lifting Eye Free-Spool Winch Pulling Hooks Anchor Connection 1,200 lbs. Heavy Duty Winch 100 ft. 7/16 Wire Cable Power Switch With 32 ft.

41 OSHA Requirements OSHA 29 CFR Part Subpart P-Excavations: OSHA s excavation standard contains many different requirements as well as several appendices that can be confusing at first glance. The following information summarizes the main requirements in order to help contractors prepare the job site for OSHA inspections. Prior to digging, the contractor shall locate and identify all underground utilities such as sewer, telephone, fuel, electric, water lines, etc. that may be encountered during the excavation. The contractor must designate a competent person or qualified person to assess the excavation and determine that it is safe for project personnel to enter and work. All surface encumbrances such as signs, trees, fences, poles, sidewalks, etc. that create a hazard to employees must be removed or supported during the excavation. All excavating must maintain a minimum of 10 ft. from overhead power lines rated 50 kv or less, with 0.4 in. of clearance added for every kv over 50. Support systems shall be provided to ensure the stability of adjacent structures endangered by excavation operations. If excavation is over 5 ft. deep, a protective system such as a trench shield shall be used to prevent a cave-in. The contractor must provide a safe means of entering or exiting any excavation over 4 ft. deep. A means of egress from a trench such as a ladder, ramp, or stairway shall be located within 25 ft. of workers. In excavations over 4 ft. in depth, the potential for the accumulation of hazardous gases or vapors must be realized. Shielding systems shall be installed and removed in a manner that protects employees from cave-ins, structural collapses, or from being struck by any part of the support system. Shielding systems shall be installed in a manner to restrict lateral or other hazardous movement of the shield in the event of a sudden collapse. The bottom of the shielding system can not be positioned greater than 2 ft. above the bottom of the excavation. Shielding systems and their components shall not be subjected to loads which they are not designed to withstand. Shielding systems and their components shall be securely connected to prevent predictable failures. The removed spoil shall not be stockpiled closer than 2 ft. from the excavation s edge. Backfilling shall progress together with the removal of support systems from excavations. Any excavation left unattended must be barricaded, fenced or otherwise protected against accidental entry by pedestrians. Employees exposed to vehicular traffic must wear a high-visibility vest, and the excavation must be protected from traffic. If employees must cross over an open excavation, a safe means must be provided so that the employees do not have to jump across the trench. No workers shall enter or work in excavations where standing water is visible unless adequate protection is used. No employee shall be permitted underneath loads handled by lifting or digging equipment. If the competent person finds evidence of a hazardous situation that may result in a cave-in, protective system failure, a hazardous atmosphere, or other hazardous conditions, exposed employees shall be removed from the hazardous area until the necessary precautions have been taken to ensure safety. 41
