Compressed Schedule Calls for Cross-Trade Coordination

Saturday, September 20th, 2014

lakes_internationalThe side-effects of the deluge of rain we received this last spring are still being felt today. On top of flooding and lake closures, there was a direct impact on construction projects that had to push back start dates because of wet soil.

New building construction for the Lakes International Language Academy (LILA) adopted an aggressive new timeline to combat this obstacle. The K-6 charter school looked to build upon the success of its tuition-free immersion program (Spanish or Chinese) that follows an accredited International Baccalaureate Primary Years curriculum in the form of a new facility.

The rain, while good for flowers, turned the work site into a challenge. The foundation’s soil turned to soft clay, making for a less-than-ideal work environment. In fact, a concrete composite had to be mixed into areas where soil integrity was most vulnerable, effectively turning the school’s new parking lot into a great big cinder block.

Collaboration between Egan and Kraus-Anderson’s Project Manager Jake Boerboon and Superintendent Jesse Fiskewold were essential to project success. Even closer coordination was required than is customary for a project like this. Potentials for lost-time or further delays were addressed and resolved before the fact, creating an extremely well-organized work model.

Design/Build was also a huge factor in facilitating the accelerated timeline. Thanks to Egan doing the design and construction, many issues were resolved before they could reach the field. Without this, on-site problem solving would be a necessity and could have delayed the project further.

The construction team benefited greatly from prefabrication on this project. Circuits and feeders were crafted in-house and pre-assembly of the duct helped reduce installation time in the field. Close coordination between mechanical and electrical also minimized penetrations in the precast and allowed coordination of hanger systems, nearly cutting the initial estimate time in half.

Egan also supplied the academy’s building automation system. The weather delay shortened the installation timeframe significantly, requiring work to be completed in about a week.

The project finished on time, giving the school about two weeks to furnish and organize the building to be student-ready for the Fall.

The Lakes International Language Academy Project is a newly constructed, 43,000 square foot, two-story facility that included two parking lots and a gymnasium. The building’s automation system included integrating seven Lennox RTUs, installing controls on VAV boxes, and interlocking the kitchen make up unit with miscellaneous exhaust fans.

Summer of School Upgrades and Installs

Friday, September 19th, 2014

anoka-hennepin-school-outsideEvery summer, Egan Company’s Building Systems & Services (BSS) group upgrades or installs new building automation or fire systems in schools across Minnesota and Wisconsin.

Egan completed work this summer in over eight school districts, including St. Paul Public Schools, Eden Prairie Schools, Anoka-Hennepin School District, School District of Clear Lake, and St. Michael-Albertville School District. All of this work is compressed into a three-month timeframe and equates to over 20,000 hours of manpower.

The building automation system controls everything from air handling units to VAV boxes to pool converters to lighting. Many schools also incorporate energy efficient systems to produce lower utility bills. The fire systems in the schools provide smoke management systems, advance detection, voice evacuation and exit technology, and sprinkler system monitoring.

The installation of these two systems can prove challenging, especially in such a short timeframe; however, Egan simplifies the project process by providing system engineering, design, installation, and start-up and commissioning to finish the job quickly.

All systems were updated before school started this Fall. Year round, Egan also provides maintenance to these–and other–school districts.

“Every summer we roll up our sleeves for various schools,” said Tom Addabbo, Egan Account Manager. “It’s always a challenge to help bring these schools back online before the school year starts. Fortunately, our field team does it year after year and knows what it takes to meet these tight timelines.”
