Project Spotlight: Miranova Helicopter Lift

In the autumn of 2011, Bruner technicians performed routine maintenance on seven make-up air units at One Miranova Place in Columbus, Ohio.  The seven make-up air units providing fresh air to the kitchens of over one hundred condominiums were found to be unsafe for operation, due to cracks in the gas fired heat exchangers, which could allow carbon monoxide to enter the living spaces of the tenants.

To provide a temporary repair, Bruner welders sealed the leaks, allowing the units to remain operational until new make-up air units were available for installation.  These repairs, while temporary, allowed the Board of Directors at Miranova time to investigate several options for a long term solution.

After receiving several proposals, the Board decided to accept the solution provided by the Bruner Corporation.  With advice from Prater Engineering, the Board accepted the offer from Bruner to remove the aging make-up air units, and install seven new “Aaon” 100% fresh air make-up air HVAC units.  The new Aaon units, with technological advances not available 15 years ago, provide increased energy efficiency and extended longevity.

One of the major obstacles facing Bruner was the difficulty in removing the existing units and mounting the new units to the rooftop of One Miranova Place, nearly 340 feet above street level.  After consulting with several crane companies, it was determined that the most economical means of replacing the units would be to utilize the services of Midwest Helicopter, a company specializing in lifting equipment inaccessible to conventional hoisting systems.

In preparation for the helicopter lift, Bruner technicians, led by Bob Hoffman and Don McNeal, [John Magill and Brian Caton also] spent many hours to assure that all components were able to be safely and efficiently lifted to and from the building.  Their efforts paid off, as the total time required to remove seven units and mount seven new units was under one and a half hours, nearly a fifth the time required for conventional hoisting methods.

With an extreme focus of safety and customer satisfaction, Bruner has once again demonstrated our commitment to excellence.  Even during this potentially dangerous helicopter lift, the interruption of business to Miranova One (condominiums) and Miranova Two (office building) was negligible.

Hats off to the Bruner team for making this event run so flawlessly.

 

Discover the Value of HVAC Preventative Maintenance

In a way, HVAC preventative maintenance can be compared to that of your car. If you spend $30 on an oil change in your car, you would save $3,000 on a new engine. If you don’t change the oil and replace belts and filters, the engine will lock up and the vehicle won’t operate. Proper preventative maintenance for HVAC equipment will basically do the same thing. Maintenance isn’t expensive compared to what you might need to spend if your system degrades, and therefore ultimately fails. An example is provided by Anthony Shaker, vice president of operations at UNICO Newton, MA:

If you have a piece of equipment that costs $10,000 to maintain and has a forecasted life of 10 years if properly maintained, you will spend only $20,000 from first cost to replacement cost at the 10-year mark, assuming it would cost $10,000 again to replace it at the end of its lifecycle. However, if you did not properly maintain the unit and it failed at the 5-year mark, you would need to spend $10,000 to replace it after 5 years and then replace that same unit again in another 5 years if you continued to not perform maintenance. Your total cost would be $30,000.

Bruner agrees there are a few key concepts to pay attention to. First, HVAC system maintenance isn’t expensive compared to what you might spend if your system degrades. Second, the first place to turn when building a successful HVAC maintenance plan should be the manufacturer’s operating and maintenance manual. Don’t overlook these maintenance manuals because they provide a concrete blueprint for the steps you need to take to maintain chillers, boilers, motors, air-handling units—every piece of equipment in a building’s HVAC system! Next, by tracking different system indicators such as oil temperature, RPM speed, etc. you can pick up on many emerging problems before they reach a crisis situation. Finally, it’s important to do a life-cycle cost analysis when determining if you should repair or replace an aging HVAC system component. Ideally, the ratio of spending for HVAC systems should be 70% preventive maintenance and 30% corrective maintenance.

Bruner’s planned, predictive, and preventive approach to HVAC system maintenance results in your ability to control costs, extend the life of the facility and its systems, thereby improving operations and cash flow.

Employee Spotlight: Doug Linnabary

Dough Linnabary has been with Bruner since March of 2006. Currently working under the title of Job Support, Doug looks over the daily progress of job sites, creates schedules and makes sure they are carried out, over-sees and approves fabrication, and schedules materials and equipment. According to him, he is “basically the chief cook and bottle washer”.  His favorite part of the job thus far is seeing Project Noble come to a close. Project Noble has been very challenging to Doug in many ways, too many of which to list. Doug’s always liked completing a goal with his workers and standing back and being proud to put Bruner’s name on it.

Outside of Bruner, Doug likes to spend time with his family. He is very close to his four children and wife of 28 years this September. He isn’t quite sure “how she has put up with him this long”. He is also politically involved in the community that he lives in, loves to hunt, fish, water and snow ski, go boating, garden (not just flowers, vegetables too!), go motorcycling, and also work with wood. His favorite food is a traditional German dish called Rollauden. When asked what his favorite spots team was, he responded “the Browns of course”. Doug’s favorite vacation spot is Boone, North Carolina. His favorite colors are green, blue, and orange and specifically in that order! Finally, Doug’s favorite day of the week is “any day above the dirt”.

Another spotlight complete on one of our hard-working, trustworthy Bruner employees! Does Doug sounds like someone you would like to work with? Check out our career page for the latest openings and apply today if applicable.

Build Green with LEED for Schools

The LEED for Schools Rating System recognizes the unique nature of the design and construction of K-12 schools. Just to clarify, LEED stands for: Leadership in Energy and Environmental Design. LEED for Schools is the recognized third-party benchmark for high-performance schools that are healthy for students, comfortable for teachers, and cost-effective for budgets.

Studies have shown that students learn better in a quiet, comfortable, and properly lit environment. Because of this and many other factors, greening our schools has become a high priority.

LEED is not meant to be used as the only measure in determining whether a project is green, and in order to achieve green goals it is essential that design teams (including owners and contractors) take an integrative approach and view the project as a whole.

Using an integrated design approach, LEED promotes improved practices in:

  • Site selection and development
  • Water and energy use
  • Environmentally preferred materials, finishes, and furnishings
  • Waste stream management
  • Indoor air quality and occupant comfort
  • Innovation in sustainable design and construction

Bruner is currently working with Dublin City Schools in an effort to promote LEED for schools–check out our project page for more information. With this project alone, Bruner has been recognized by AEP Ohio for our “commitment to energy efficiency and the environment”. As a result of our collaboration, Dublin City Schools will reduce energy use by 739,410 kWh per year and reduce CO2 emissions by 632.8 tons, which equals as many as 100 cars off the road per year! Consider LEED for your school, and contact Bruner to find out what we can do to help.
