ASHRAE Presentation on Lawyer’s Mall Underground Infrastructure Project

Kibart (Prime Consultant) along with CPF Underground Utilities (General Contractor) were invited by the Maryland Department of General Services (DGS) to participate in a presentation at ASHRAE’s Baltimore Chapter September meeting.

Kibart discussed the current construction project to replace the underground infrastructure at Lawyer’s Mall in Annapolis, MD. The project is a multi-phased project to replace aged underground infrastructure utility systems (steam, chilled water, water, storm water, gas, electricity, and telecommunications) that sustain historic state buildings, including the House of Delegates Building and the three buildings (Legislative, State House, and Governor’s House) that make up Lawyer’s Mall.

Originally, the project’s scope of work only included the replacement of the steam system and was to be constructed in 2019. During the design phase this past winter, the system experienced multiple steam leaks that prompted emergency measures. We needed to accelerate the design schedule and the start of construction. While designing the replacement of the steam line, DGS determined that it would be beneficial to also replace the remaining underground utility systems.

“It made sense to evaluate all of the systems while were already doing underground work in the area”.  - Senior Mechanical Project Engineer, Joe Del Pilar.

By piecing together information gathered from as-built drawings, past construction photographs, interviewing DGS personnel along with utilizing utility locating methods such as ground penetrating radar (GPR) and performing test pits, the design team was able to develop an existing utility site plan with accurate information. With the services of Multivista, a company that specializes in construction photographic and video documentation, Kibart will be able to hand over accurate state-of-the-art as-built drawings, photos, and video to the owner that will prove invaluable over the life of the new systems in terms of maintenance and future projects.

We were especially excited to work on this project because it gave us an opportunity to provide innovative solutions that the owner can readily notice and appreciate.

“Working with the entire team including DGS, civil and structural engineers, surveyors and contractors has been a great experience. With a clear mission, and teamwork in mind the team was able to work together, overcome challenges, and learn throughout the process. The responsiveness of the Department of General Services, Carroll Engineering and CPF Underground Utilities has been key to achieving timely results – even as the scope grew”.
