Mechanical and Plumbing Engineering

The mechanical and plumbing systems in a building determine whether people inside are comfortable, safe, and productive — and whether the facility can operate efficiently over the long term. HVAC, ventilation, central plant infrastructure, and plumbing systems are among the most complex and costly building systems to design, install, and maintain, and getting them right from the start pays dividends throughout the life of a facility.

Our team designs systems for a wide range of facility types, from civic and institutional buildings to correctional facilities and industrial environments. We approach every project with an eye toward energy efficiency, long-term capital performance, and practical constructability. DLZ integrates mechanical, plumbing, and fire protection systems into a coordinated whole that works well on day one and continues to deliver value for decades.

Featured Capabilities

Central Plant Design Indianapolis-Marion County Criminal Justice Campus

Central Plant Design

Reliable heating and cooling starts with a well-designed central plant. We design boiler, chiller, and cooling tower systems sized and configured to meet facility loads efficiently, with long-term operational performance and maintainability in mind.

Airside Design Franklin County Corrections Center

Airside Design

Effective air distribution is critical to occupant comfort, indoor air quality, and energy performance. DLZ teams design air-handling units, variable air volume systems, and building and process exhaust systems tailored to the specific demands of each facility type and use.

Plumbing Systems Franklin County Corrections Center

Plumbing Systems

Reliable plumbing is fundamental to how a building functions day to day. We design domestic water, sanitary, and stormwater systems alongside water heating and conditioning solutions, coordinating closely with mechanical and structural disciplines to deliver integrated, code-compliant building performance across a wide range of facility types.

Fire Protection Franklin County Corrections Center

Fire Protection

Fire protection systems are a critical component of building safety and code compliance. We design systems that meet applicable codes and standards for the facility type, integrating fire protection with mechanical and plumbing systems to support a coordinated, constructable design.

Correction Facility Mechanical Design Franklin County Corrections Center

Correctional Facility Mechanical Design

Correctional facilities present unique mechanical design challenges around durability, safety, and water management. DLZ brings specialized experience in designing systems for these environments, where reliability, tamper resistance, and operational control are as important as comfort and efficiency.

Facility Assessments

Before investing in mechanical system upgrades or replacements, owners need a clear picture of what they have and what it will cost to improve it. We conduct thorough facility assessments that evaluate existing mechanical systems, identify deficiencies, and provide the information needed to plan capital improvements with confidence.
