"American Constructors has been building Schools in Central Texas since 1986 and our success in these complex, time sensitive, and challenging projects is greatly dependent on our key subcontract partners. Allied Underground has been and continues to be one of those key partners.

Allied Underground has completed countless projects for us over the years and has never let us down. Underground work is not easy, and few can perform quality on time work at a high level like Allied. Schools must open on time, every time, and we have no chance to make this goal without timely performance of underground utilities in the early project stages. Thank you, Allied, for what you do."

"Rosenberger Construction has had a great relationship with Allied Underground over the past 6 years and have worked together to build many successful multi-building, Industrial Parks during this time.

From their office to the field, they go above and beyond providing the needed support and staff to make and exceed the demanding project timelines for their scope of work. The quality and speed of construction is second to none."

“We’ve been building industrial parks across North and Central Texas for decades, and Allied Underground has consistently proven to be a reliable and valued partner for our underground utility needs. Their in-depth knowledge of the Central Texas market and familiarity with local jurisdictions has been instrumental in helping us close out projects.

Beyond their expertise, they bring the right equipment and skilled crews to every job, allowing them to meet aggressive timelines. Their ability to consistently deliver under pressure has made them a key part of our project success.”

"The thing about multifamily projects is that everything’s moving at once—and you need a site team that won’t blink under pressure. Allied Underground never flinched. Their attention to detail on utility work and stormwater systems was first class, and they stayed on schedule despite weather delays and site changes. Thanks for being a team that we could count on every step of the way."

"Allied Underground goes beyond being just a subcontractor—they’re a vital partner in our sitework endeavors. During our recent commercial development project, they expertly managed utility installations, storm drainage connections, and a complex retention system with flawless execution.

What stood out most was their leadership’s commitment: always accessible, deeply engaged, and fully dedicated to our project’s success. That level of responsibility and care is truly exceptional."
