Algood City Municipal Building Design Begins

Maffett Loftis Engineering has been selected to provide engineering services for the new Algood City Municipal Building, located in Algood, TN. The facility will allow multiple city functions to operate under one roof. This facility will benefit the city greatly by increasing productivity. It is an honor to be working with AEI (the architect) and the city to provide Mechanical, Plumbing, Electrical, Fire Sprinkler, and Fire Alarm design for the project. Construction is scheduled to start in November 2011. Project completion should be in November 2012.

38 KW Ground Mounted Solar Array

Maffett Loftis Engineering was hired by Total Quality Environmental (TQE) to design a 38 Kilowatt ground mounted solar array system for a local business. This solar system will utilize the most efficient solar panels on the market. All energy produced will be sold to Cookeville Electric Department and will become a part of the electrical utility system. Cookeville residents will participate in helping the environment by using Renewable-Green energy produce by this solar power generation system.

Arc Flash Seminar

Maffett Loftis Engineering hosted an Arc Flash Training Seminar for the State Electrical Section officials and local electrical inspectors. The seminar was designed to explain Arc Flash hazards, OSHA and NFPA requirements, and avenues to mitigate the hazard. MLE has been invited to provide a presentation about Arc Flash hazards to the annual International Association of Electrical Inspectors (IAEI) fall meeting as well as other industrial leaders in the Upper Cumberland region.

Arc Flash Analysis

Maffett Loftis Engineering has been contracted to perform an Arc Flash analysis for the new Putnam County School – Prescott South. The facility has two 4000 amp, 480 volt, three phase services and one smaller service for the sports fields. In order to perform the analysis, Selective Coordination and Short Circuit studies was completed. The report consisted of graphical one-line diagrams, written reports, time current curves, work permits, and printed Arc Flash labels for equipment. Advanced engineering analysis software was utilized to provide the best results possible.

This year we expanded our engineering capabilities by purchasing EasyPower software. EasyPower is an engineering analysis tool that allows us to model a facilities electrical power system to perform studies and tests in order to evaluate design safety concerns. By adding this capability to our family of services, we can provide fast and competitive service.

National Fire Protection Association (NFPA) and Occupational Safety and Health Administration both are now requiring Arc Flash analysis on non-residential facilities.

“OSHA recommends that employers consult consensus standards such as NFPA 70E-2004 to identify safety measures that can be used to comply with or supplement the requirements of OSHA's standards for preventing or protecting against arc-flash hazards.” www.osha.gov

Clarksville Marina and Dry-Stack


Clarksville Marina on the Cumberland River in Clarksville Tennessee has selected the architectural and engineering team of Maffett-Bouton & Associates and Maffett Loftis Engineering to design its new Dry Stack Boat Storage facility. The new facility will be based on Maff-Stack Boat Storage technology per a license agreement with Vertical Yachts Storage Systems. The Maff-Stack system utilizes an overhead bridge crane to transport boats from the water to the storage racks. This will be the second boat storage facility constructed using the Maff-Stack technology. The first facility, The Port Marina in Ft Lauderdale Florida has been operational since January of 2006 and has proven to be a technological wonder setting four boat storage records.

The Clarksville Marina will accommodate 192 boats on six levels. Boats up to 34 feet can stored. Maff-Stack technology was selected for this project because it can easily accommodate the challenges of the site. The building will be located in a flood plain susceptible to being submerged with up to 8 feet of water. This prohibits the use of traditional fork-lifts. Also, the water level fluctuation during normal conditions can be easily handled with the overhead crane, eliminating the need for an extensive fork-lift access ramp.

Maffett-Bouton & Associates (creator of rendering shown above) will provide architectural design for the facility. Maffett Loftis Engineering will provide mechanical, plumbing, electrical, and fire protection design. Structural engineering is being provided by Sky Structures out of Las Vegas, NV. Site and civil design is by JJR out of Madison WS.

Renewable Energy Power Plant


It’s great to be involved in new ideas that can benefit the community and help the environment at the same time. Maffett Loftis Engineering is designing the mechanical, plumbing, electrical, fire protection, and fire alarm for a biorefinery power plant just north of Dunlap, TN. This biorefinery has the ability to produce 2 mega-watts of electricity without polluting the environment.  The developer plans to develop the area around the biorefinery and wants “...to become self-sustaining, disposing of its own waste while producing much of its own energy with very little environmental impact. The patented biorefinery is the heart of the idea.” (taken from the Chattanooga Times Free Press)

Cooper Recycling Vehicle Shredder

Maffett Loftis Engineering has designed the electrical system for a state of the art recycling center in Overton County, TN off Hwy 111. The new recycling equipment can shred scrap metal, but it’s specific use is to shred vehicles. This robust equipment can shred a can in small hand size pieces in about 20 seconds. The shredder is driven by two 2,000 horse power DC motors. The facility has three electrical entrances totally over 10,000 amps. The electrical demands are so large that Upper Cumberland Electric Coop had to install a new primary line from a new sub-station 5.5 miles away.
