Our team provided engineering services for a five-story, 720,000 ft² Adult Detention Center and a two-story, 82,000 ft² Sheriff’s Office for Marion County, Indiana and the City of Indianapolis.

Our team worked with North Mechanical, Sexton Mechanical, Bright Sheet Metal, and ERMCO prim trade contractors to provide design-build mechanical, electrical, and plumbing engineering for a five-story, 720,000 ft² Adult Detention Center and a two-story, 82,000 ft² Sheriff’s Office for Marion County, Indiana and the City of Indianapolis. The buildings are on a campus which includes a 14-story court building and a central utility plant (CUP) building. We coordinated utility requirements with the CUP engineers. Revit was utilized for preparing the Building Information Model and the construction documents. 

The project was designed utilizing International Building, Mechanical, and Plumbing Codes and the National Fire Protection Agency codes and guidelines of the American Correctional Association (ACA) for correctional facility operations. The following is a brief description of mechanical, plumbing, electrical, and systems designs. 

The mechanical heating, ventilation, and air conditioning system consists of obtaining chilled and hot water systems from the CUP building to serve Air Handling Units in the roof penthouse and fan terminal units throughout the building. Computer Room Air Conditioning Units were engineered to serve cooling to all telecommunications and security rooms. The mechanical, plumbing, and electrical systems are monitored by a building energy management system. An energy model was developed in accordance with ASHRAE Standard 90.1 comparing the building with a baseline model in order to calculate energy savings to obtain LEED version 4.0 Silver Certification. 

The plumbing system consists of obtaining hot water from the CUP building and includes engineered distribution piping, sanitary and storm sewer piping, venting, and roof drains. The plumbing system was designed to reduce water usage by 52% less than the baseline standard to obtain LEED version 4.0 Silver Certification. Gas service was provided to the Sheriff's building to serve kitchen and laundry equipment. 

The electrical system consists of a 6000 ampere, 480Y/277volt, 3-phase main service panel located in the Sheriff's office to serve all mechanical equipment, plumbing equipment, step-down transformers (480volt – 208Y/120volt, 3-phase), distribution panels, and branch circuit panelboards in both the Sheriff and Adult Detention Center buildings. The main power comes from the CUP building which has backup power from an engine generator set. 

The lighting consists of energy-efficient LED luminaries throughout the buildings. 

A fire alarm/mass notification system consisted of a main addressable panel with initiation and notification devices as required by NFPA standards. 

The buildings’ telecommunication systems include fiber-optic backbone cables from the main distribution frames (MDF) to intermediate distribution frames (IDF) and Security Rooms. Category 6 horizontal cabling from IDF rooms equipment racks to workstation devices throughout the facility. 

Project phases include Pre-Design, Design Development, Construction Documents, and Construction Administration Phases. The project is being executed utilizing the design-build delivery method. Design deliverables include: 

  • Drawings (including BIM model) 
  • Design Criteria Summary 
  • Energy Model 
  • Specifications 
  • Calculations 
  • LEED templates and supporting documentation 

Construction administration services include: 

  • Review of shop drawing submittals 
  • Participation in construction coordination teleconferences 
  • Responding to contractor-generated Request for Information 
  • Performing field observations and providing field reports and final punch list 
  • Preparation of record documents based on field-generated redline as-built mark-ups
