Guest Article by Alan T. (Ted) Sheppard

In today’s market place competition tends to drive prices down. One solution to having a lower cost to meet the lower prices demanded by the market is innovation. We all thought we were getting smarter when we could just get a bigger crane to do our work. This may be true and even helpful at times, but bigger cranes can be expensive. What we should be doing is finding new ways to use older, owned equipment.

If we have to place a heavy load in a small isolated space, we could try to convert an existing crane boom or, even better, an old derrick boom into a gin pole or a Chicago boom. You could also build a wheeled buggy to carry your load into the confined area. Think about it. Maybe it won’t work, but then again, maybe it will.

When I was with Tri State Steel Construction, we had a project where we had to install steel grating for a bridge deck. The Engineer of Record would not permit us to use a crane or any heavy lifting equipment that ran on the grating before the concrete was poured. We decided to design and build a jinniwink. This was a vertical column with a horizontal beam across the top. It was secured to a moveable frame, and its load falls came from an air hoist on the frame. We were short on work at the time; so we had four of our foremen build it in the yard. They decided to add bracing here and there until it looked like a prehistoric bird. We called it the Pterodactyl. We put that name on the drawing submitted to the state for approval. The general contractor and all of the workers liked the name and used it throughout the job. We moved the frame with another air hoist. We also designed a buggy, moved by the air hoist, to take the grating sections out to the Pterodactyl. It was inexpensive to build, it met the engineer’s requirements, and lo and behold, we made money.

I have built gin poles out of wood with rope falls for load and foot guys. Now that is really inexpensive. When I was with Bethlehem Steel we designed and built out of pipe a one-ton guy derrick. Also with Bethlehem we had a building to erect that was a guy derrick job, but it was so narrow that the back guys would be overstressed when we went to the street. We took the upper rotating assembly of a 20-ton Lorain truck crane and put it on a moveable frame in the center bay of the building. We moved it back and forth in the long direction and used air motors and four of the next tier’s columns to jump the crane two floors at a time. When we got to the top, we turned the wheels around, moved it to the edge of the building, and dismantled it with a truck crane on the ground. This was not a new idea. Our project manager had seen a similar arrangement in Pittsburgh being used by another erector. Our project was in Detroit. Evidently our competitors had not been to Pittsburgh at the right time. Innovation does not mean it has to be your idea. You just have to be willing to implement another’s ideas.

I have been fortunate in having worked with a lot of unusual equipment arrangements. I worked on a blast furnace that was built from the ground up in between two other blast furnaces. Space was at a premium. The main erecting equipment was a 35-ton stiff leg derrick on a square tower. In order to find the main hoisting engine, you had to follow the cables through a maze of piping and ductwork. On each of the two forward legs of the tower was a Chicago boom. There was a Chicago boom on a stove that erected the dust catcher and helped the stiff leg with the main section of down comer. The stack was erected with a stack rig inside the stiff leg’s tower. We did have a truck crane for the erection of the cast house.

Innovation is not limited to special equipment. Different ways of doing things also help your cause. If you are using a Chicago boom on an exterior column of a building to remove other equipment or materials, tilt the boom base so that the loaded boom swings outboard on its own and you only have to pull back (by hand) an empty boom. If you want to have a lifting beam made out of pipe with a cable bridle for hoisting, and you only want compression in the pipe (no bending), offset the bridle hitch from the load hitch so that the bending moments cancel each other. This makes the pipe smaller and more efficient. If you want to use a building’s beam to support a temporary load, and that beam will not take it, shore it from the beam below, distribute the load to each beam in accordance with each I/L ratio ( moment of inertia over length) and check the shore for the amount of load to be transferred. Usually a 6” x 6” timber will suffice. Don’t go to the trouble of reinforcing the existing beam. There are a lot of these things to use. You know a lot of them. Put on your thinking cap and work on your memory. Most of the ideas you have had in the past can be used again.

When you work in industrial plants where you cannot disrupt production, or places like Disney where you cannot disrupt the movement of the customers, innovation really comes into play. When you have to rehab an existing structure, look for different ways to lift or move the elements of the structure; old stuff out and new stuff in. You can build low-capacity guy derricks, stiff leg derricks, Chicago booms and gin poles out of timbers, say 6”x 6” or 8”x 8”, and pipe of various diameters. These can be very cost effective. You will find that your workers like the idea of working with something different, and their productivity will go up. There is a great deal of personal satisfaction, too, when you feel that you really have built a better mouse trap.

Like all erection schemes innovation is a combination of engineering and common sense. Once you build something, do not throw it away. It can be used again, or it can be modified to use again. Each time this is done, your cost exposure goes down.

I am sure that my crane rental friends are miffed about this. My last piece of advice is that if all else fails, rent a big crane.

Contracts

Construction Contracts for Subcontractors – Are You Covered? - back to top

Blog by Ron Thompson

Introduction by Bruce Basden:

This is the time of the year that companies review policies and procedures. We have found that we sometimes wander away from good business practices in our efforts to get a job going, leaving ourselves vulnerable to bad contract language. This article from Ron Thompson points out some things we need to watch for when reviewing contract terms.

You have probably been there a 1000 times! You have bid a job, fairly certain you will get the job and then the old, dreaded 40-page “Subcontractors Agreement” comes flying in from your customer. Sign and send back is the request. Digging through the Killer Subcontract Agreement can be onerous, written in nearly incomprehensible terms, then you come to the Indemnity section and the indemnification clause creates a fairly straightforward obligation: the subcontractor (you) will defend and pay damages if the General Contractor, Owner and Architect are sued for injury arising out of the subcontractors’ (your) work.

Knowing Risk Transfer

Contractual risk transfer is generally achieved through two types of provisions. The contract may include an : “indemnification” clause, an “additional insured” clause (sometimes part of a broader “insurance” clause), or both. These provisions create unique obligations for the subcontractor (you) and should be carefully reviewed because it could possibly create additional exposures that may not be covered in your General Liability policy.

Coverage Issues on Subcontractors General Liability Policy

By signing the Killer Subcontract Agreement in its original form without negotiating more favorable terms, may be exposing your company to additional unwanted exposure and potential uncovered claims. In the indemnity section, the contract usually states that you (the subcontractor) will hold harmless the General Contractor, Owner and Architect for all claims, damages, etc for all liability arising out of the subcontractors (your) work, in essence requiring you to handle, indemnify and defend claims caused by the General Contractor’s negligence, even in the absence of fault on the part of the subcontractor (you). The General Contractor or Owner may have had faulty general supervision, failed to provide a safe place to work or failure to take reasonable precautions and adopt proper safeguards to protect workers from injuries, which you the subcontractor had no fault in. But the definition of all liability arising out of your work could potentially drag you (subcontractor) in to defend and indemnify the GC and Owner.

Here Is the Coverage Problem

Many court decisions applied coverage even when the result of subcontractors (your) negligence was absent because of the broad interpretation by the courts of “ liability arising out” definition of subcontractors work, found in the construction agreement. In 2004, insurance carriers changed the wording in the additional insured endorsements on your general liability policy to the injury or damage must be “ caused, in whole or in part” by subcontractors acts or omissions. The revised wording is more restricted and narrows the definition of what your liability coverage offers. Your coverage now specifically states that in order to indemnify the GC, Owner and Architect, the injury or damage must be directly caused by you in whole or in part. The “ liability arising out of” language is gone due to its broader application and coverage for additional insureds. This is good, you think?

Why Is This Bad for Subcontractors?

If the subcontractors agreement mandates that your policy grants the GC, Owner and Architect additional insured status for injuries and claims “ arising out of” subcontractors work, and your general liability policy restricts coverage to claims to only “ caused in whole or in part”, there is a disconnect where the contract you signed doesn’t match your insurance coverage in your liability policy. The contract language is much broader than what your liability policy covers.

When this happens and you are tendered a claim or lawsuit by the GC, Owner or Architect, the dreaded coverage disclaimer letter arrives in the mail from carrier stating “no coverage”, you may be stuck with an uncovered claim and possible Breach of Contract exposure which usually isn’t covered by the policy either. The contract you signed states “ arising out of or connected to” your work, but your insurance policy states coverages for claims “caused in whole or in part” by your work. 

Conclusion

So be diligent in reviewing your construction agreements and make certain through your attorney and/or insurance advisor reviews the coverages in your general liability policy are sufficient to address the exposures that you have agreed to in your construction contract. Parties to construction contracts (specially subcontractors) must use great care to determine if proper coverage is in place to avoid a potential coverage disaster. Don’t just sign the contract and send back without thoroughly reviewing and negotiating more favorable terms.

OSHA

OSHA Proposes Change to Injury/Illness Data Collection - back to top

The Occupational Safety & Health Administration (OSHA) is proposing to revise its Occupational Injury and Illness Recording and Reporting regulation by restoring a column on the OSHA Form 300 to better identify work-related musculoskeletal disorders (MSDs). The rule does not change existing requirements for when and under what circumstances employers must record musculoskeletal disorders on their injury and illness logs. It would require employers to place a check mark in a column for all MSDs they have recorded. "Restoring the MSD column will improve the ability of workers and employers to identify and prevent work-related musculoskeletal disorders by providing simple and easily accessible information," said Assistant Secretary Michaels. "It will also improve the accuracy and completeness of national work-related injury and illness data." For more information, read the news release and Federal Register notice.

Construction Standards

Sustainable Design and Construction: From Voluntary to Mandatory? - back to top

By Angela Richie Stephens, Stites & Harbison

A new standard, similar to LEED, may soon apply to all new public and private construction and major renovations, except for low-rise residential buildings.

On January 26, 2010, the American Society of Heating Refrigerating and Air-Conditioning Engineers (ASHRAE), the Illuminating Engineering Society (IES), and the USGBC published ASHRAE 189.1, a new standard for the design of High-Performance Green Buildings, after being approved by the American National Standards Institute (ANSI) on January 22, 2010. ASHRAE 189.1 was written such that it can be adopted by states and incorporated into building codes.

On January 26, 2010, the American Society of Heating Refrigerating and Air-Conditioning Engineers (ASHRAE), the Illuminating Engineering Society (IES), and the USGBC published ASHRAE 189.1, a new standard for the design of High-Performance Green Buildings, after being approved by the American National Standards Institute (ANSI) on January 22, 2010. ASHRAE 189.1 was written such that it can be adopted by states and incorporated into building codes.

In 1998, the U.S. Green Building Council (USGBC) created the Leadership in Energy and Environmental Design (LEED) Green Building Rating System. With the exception of 18 states that mandate state-owned buildings be designed and constructed to achieve a LEED Silver rating or higher, LEED is a voluntary program that private owners may choose to adopt and apply to the design and construction of their buildings.

In 2004, those 18 states began passing regulations that mandated sustainable design and construction practices (such as LEED certification) for state-owned buildings. Some states that have mandated sustainable design and construction practices for public buildings are now considering sustainable design and construction practices for private construction through the development of green building codes. As mentioned above, LEED was written as a voluntary program, and was not written to be enforced as a building code.

On January 26, 2010, the American Society of Heating Refrigerating and Air-Conditioning Engineers (ASHRAE), the Illuminating Engineering Society (IES), and the USGBC published ASHRAE 189.1, a new standard for the design of High-Performance Green Buildings, after being approved by the American National Standards Institute (ANSI) on January 22, 2010. ASHRAE 189.1 was written such that it can be adopted by states and incorporated into building codes. This new ANSI standard, if adopted by a state, will apply to all new public and private construction and major renovations, except for low-rise residential buildings.

ASHRAE 189.1 is similar to LEED in that it includes requirements relating to site sustainability, water use efficiency, energy efficiency, indoor environmental quality, the building’s impact on the atmosphere, materials and resources, and construction and plans for operation. It is ASHRAE’s intent that the 189.1 standard will compliment LEED, and will serve as the baseline for LEED or other similar rating systems. Some examples of ASHRAE 189.1’s requirements include mandating that (1) owners or developers build on previously developed sites or on a Greenfield site within one-half mile of a developed area, (2) architects design for the future installation of on-site renewable energy, and (3) owners track energy consumption of the building on a periodic basis. A copy of the ASHRAE 189.1 can be previewed at http://www.ashrae.org/publications/page/927.

Structural Steel

Importance of Framing Selection—Part 1 - back to top

Reprinted with permission from AISC from their website.

This article is the first of two parts discussing the benefits of structural steel framing. Watch for Part 2 in the next issue.

The selection of structural steel for a building’s framing system brings numerous benefits to a project. All other materials are measured against the standard of structural steel and structural steel is still the material of choice. Following are some of the benefits of structural steel.

Speed of Construction

Other materials may be able to start field work sooner, but the rapid design, fabrication and erection cycle with structural steel will allow the framing system to finish sooner and be available earlier to other trades.

Structural steel enhances construction productivity because of its shop fabrication while maintaining tight construction tolerances. Field placed material will always lag behind the productivity curve. Productivity enhancements for construction will occur not in labor based field activities, but in shop based technology enhancements.

Technology exists today in the form of 3-D interoperability and Building Information Modeling to allow the close cooperation between designers and steel specialty contractors in the design, fabrication and erection of building structures. This technology allows designs to save both time and dollars in the construction process by integrating fabricating and erection efficiencies in the design and passing design models between analysis, detailing and fabricating operations. This is full integration is process unique to structural steel generating significant cost savings.

Rapid erection in all seasons with close tolerances being maintained for integration with other building systems and minimal construction site waste is achievable only with structural steel.

Other materials may be able to start field work sooner, but the rapid design, fabrication and erection cycle with structural steel will allow the framing system to finish sooner and be available earlier to other trades.

Lower Project Costs

Today, when competing framing systems are evaluated for projects using comparable, current cost data, structural steel remains the cost leader for the majority of construction projects. Comparative studies indicate that a structural steel framing system including decking and fire protection will typically cost 5% to 7% less than a concrete framing system on a national basis.

And that is not surprising; structural steel has remained the cost leader for construction materials over the past 30+ years. According to the Bureau of Labor Statistics the price for fabricated structural steel prices for commercial buildings increased 62% from their base date of 1980. In contrast, ready-mix concrete prices have escalated 114% during that same period. Why the difference? In 1980, 10 man-hours were required to produce a single ton of steel. Today that same ton of structural steel requires substantially less than a single man-hour. While not as dramatic, similar productivity enhancements have impacted the cost of detailing and fabrication. The end result is that the structural steel component of the construction industry is one of the few segments where significant productivity increases have occurred.

Aesthetic Appeal

Architects praise the natural beauty of steel and are excited about exposing it in the design of their structures to emphasize grace, slenderness, strength and transparency of frame.

Ocean View, MSC, Oct 2007

Bending in the Right Direction,
MSC, May 2007

Structural steel allows the project architect a greater degree of expression and creativity in their design than any other construction material as they address both the functional demands of the building and unique identity of their client. Architects praise the natural beauty of steel and are excited about exposing it in the design of their structures to emphasize grace, slenderness, strength and transparency of frame. Column-free clear spans, the use of colored coatings and the opportunity for natural lighting highlight the elegant simplicity of using structural steel.

Structural steel sections can be bent and rolled to create non-linear members to further enhance the aesthetic appeal of the structure.

Design Flexibility

From the simplest, functional structure to the complex, signature design structural steel can be readily used to accomplish the design intent of the architect and structural engineer. No other framing material comes close to structural steel in the ability to encourage freedom of expression and design creativity. IDEAS2 2008, MSC May 2008

AISC annually sponsors the IDEAS 2 (Innovative Design in Engineering and Architecture with Structural Steel) competition drawing entries from throughout the United States of recently completed structural steel projects. The range of submissions highlight the innovation and creative of project architects and structural engineers in their use of structural steel. IDEAS2 2007, MSC May 2007

High Strength

All other materials talk about high strength, but their strength is still less than that of structural steel even when enhanced by steel reinforcing. In fact, the increase in the standard strength of steel used in buildings today compared to 10 years ago is greater than the total strength of competing “high strength” materials. Structural steel is typically 50 ksi material indicating that the steel has a yield stress of 50,000 pounds per square inch in both compression and tension. By comparison, a normal concrete mix has a yield stress of 3 to 5 ksi in compression only and “high strength” concrete may have a compressive yield stress of 12 to 15 ksi. Not only is structural steel a stronger material, it also has a much higher strength to weight ratio than other materials. This results in the building being lighter and lighter buildings require less extensive and costly foundations.
