INTREN Finalizes Transaction to Acquire Miller Construction Company

Unique Woman-Controlled Board Welcomes Miller CEO Christina Ernst


June 18, 2018INTREN, one of the nation’s largest certified Women Business Enterprise (WBE) specialty utility contractors, today announced they have closed the transaction to acquire Indiana-based Miller Construction Company, Inc., a third-generation full-service electrical contracting company, which is also a leading WBE.  INTREN’s focus now is a thoughtful integration of both companies.

“An acquisition evokes a myriad of emotions for employees and our focus now is on bringing our teams together in a way that minimizes any concerns,” said INTREN CEO Kelly Tomblin. Miller has an extraordinary team and we want to make sure they continue operations with as little interruption as possible. My intention is to assemble a creative integration team that will uncover and implement the best practices of both companies.”

Miller Construction’s 175 employees join INTREN’s 1,700-strong team to provide more to complete service offering through a wider geographic reach. Company President Andy Carmean will continue to oversee Miller activities and will join INTREN as Regional Vice President serving the Indianapolis and St. Louis markets.  Christina Ernst, CEO of the Miller Construction Company, will join the woman-controlled INTREN Board of Directors, one of the few in America’s utility contractor space.

"Today, Miller employees are officially a part of the INTREN family, said Tomblin. However, we will continue to honor the Miller legacy and the three generations that build this extraodinary company. Our companies share similar roots, along with the same culture and values that are centered upon a deep customer focus, an ongoing commitment to safety, and a true caring for our employees and the communities we serve."

INTREN Founder and Board Chair Loretta Rosenmayer stressed that INTREN’s acquisition furthers her vision of creating a national full-service company. “Our goal is not only to build the best women-owned business and woman-controlled board, but to be the best overall total-solutions provider for our customers. INTREN’s and Miller’s shared values of stewardship, integrity and customer focus will guide us, and firmly support our belief that companies do well in the marketplace by doing good,” Rosenmayer added.

This acquisition is in response to requests from our customers and the marketplace. We are expanding our transmission capabilities and expertise, and adding other services such as equipment testing, vegetation management and innovative professional services while maintaining the same safety, quality, and customer focus that INTREN has provided for nearly thirty years. We are now well-positioned to grow further and be even better partners for our customers in the future,” added Tomblin.

“As a family-owned and operated WBE, Miller Construction Company is thrilled to join the INTREN family,” Christina Ernst said. “Not only does INTREN embody the principles and values of Miller Construction Company, but we provide complementary services that will help INTREN achieve continuous growth and become a total utility solutions provider. Together we are well-positioned for industry leadership that will provide creative solutions for our customers.  I look forward to serving on the Board and continuing to help advise the combined companies.”

INTREN’s acquisition of Miller Construction Company shows the industry that diverse companies can combine to create a different and innovative workplace offering.  INTREN’s latest growth to meet the infrastructure needs of the utility marketplace reflects their 30-year trajectory that was bolstered in 2017, when One Equity Partners became a minority investor, providing significant funding for future growth.

A shovel goes into the ground.This April marks the tenth annual National Safe Digging Month, reminding residents to always call 811 before any digging project. National Safe Digging Month is formally recognized by the U.S. House of Representatives and Senate and has traditionally earned the support from nearly every state governor across the country.

When calling 811, homeowners and contractors are connected to the local one call center, which notifies the appropriate utility companies of their intent to dig. Professional locators are then sent to the requested digging site to mark the approximate locations of underground lines with flags, paint or both. Every six minutes an underground utility line is damaged because someone decided to dig without first calling 811.

Striking a single line can cause injury, repair costs, fines and inconvenient outages. Every digging project, no matter how large or small, warrants a call to 811. Installing a mailbox, building a deck and planting a tree or garden are all examples of digging projects that should only begin a few days after a call to 811.

“As April marks the traditional start of digging season, we are using this month to strongly encourage individuals and companies to call 811 before they begin digging,” said INTREN Executive VP of Operations and Business Development Matthew Turk. “By calling 811 to have the underground utility lines in their area marked, homeowners and professionals are making an important decision that can help keep them and their communities safe and connected.” 

The depth of utility lines can vary for a number of reasons, such as erosion, previous digging projects and uneven surfaces. Utility lines need to be properly marked because even when digging only a few inches, the risk of striking an underground utility line still exists.

INTREN encourages area residents to visit www.call811.com for more information about digging safely.

INTREN’s Commercial & Industrial and Midwest East Electrical make seven departments in seven months to achieve one year incident-free


Intren works on underground projects near Wrigley Field in 2016In the past seven months, INTREN has documented seven departments who have reached one year without any significant safety or operational incidents, a rare milestone within the energy industry.

"The performance success we are experiencing is a result of listening to field and office employees, then implementing common sense measures developed together to create a safer work environment," said Director of Safety and Quality Tim Ayers. "We are turning our long-held INTREN vision into a safety culture that can be witnessed on our jobsites from coast to coast."

Starting with communication, INTREN has successfully improved crew members' interactions on the jobsite and throughout the company. Changes were made to reduce the size of safety meetings to increase engagement and focus on specific work-type challenges, as well as establish a streamlined approach for crew members to collaborate and execute on innovative ideas. The daily job brief was improved using our employees' ideas to create more open conversations about jobsite hazards and an ability to list barriers they plan to use.

INTREN also developed a more detailed and targeted safety training matrix that identifies three critical aspects:

  • INTREN-developed

  • Customer-specific

  • OSHA-required

In 2016, we implemented our new Safety Net audit tool, which incorporates our list of industry-wide issues we need to be focused on to ensure work is completed in the safest manner and at the highest quality. This new tool allows easy entry of all our findings with an ability to run and share reports that target our improvement needs real time. "It is certain that no one change has created this type of performance; rather, it's the culmination of all our initiatives that has helped us get to this point," said Executive Vice President of Operations and Business Development Matthew Turk. "By listening to our employees' needs and fulfilling them, our entire company has embraced our safety culture."

An attendee plays INTREN's touch screen game at ASA ChicagoINTREN's Commercial Industrial team exhibited at the ASA Chicago Construction Expo & Safety Conference March 7th at the Drury Lane Conference Center in Oakbrook Terrace, IL. General contractors and safety professionals tested their acute ability with INTREN's renowned "Safety Game"! Not that we noticed, but it was a woman (out of a sea of men) that was the game's high scorer of the day!

ASA Chicago is the most recognized association for subcontractors within the construction industry.

As Storm Stella unleashed her fury and 10+ inches of snow in the Chicagoland area on Tuesday, March 14, the transmission team led by General Forman, Andy Taft, stood up to her blustery blizzard conditions to kick off their job. Wreaking havoc with AM commuters and delaying hundreds of flights, it was business as usual for the INTREN team, in spite of very tough, white-out conditions.

INTREN was given a 3-day outage to complete the job, which was to re-conductor 1 span of 1113 ASCR with 1033 ACSS/TW to get higher clearance over a building under INTREN customer’s 138 KV Line.  The line ran parallel with another line, which was to remain hot during the job. 

Besides the weather, the job had its challenges. The line ran through the entrance and parking lot of a company’s major transportation hub in Chicago.  INTREN had to allow access to the fueling station and buildings, while maintaining protection for the company’s workers. 

The poles were light dead-end mono poles installed in the late 60s and they had to be extra cautious to support the arms during the work, so there was no damage to them.  The new wire was installed using high-temp compression dead ends and all new hardware.   It provided better clearance on the building and brought the line in to compliance with NERC standards.

The desire to make sure INTREN provided the customer with the best product and on-time was shown in the work the INTREN team did.  The foremen showed great leadership with their crews to make sure they and the public was safe.  The crew finished early and was able to open the parking lot back to the transportation company, who thanked INTREN for the great job they did and their professionalism.
