Dr. Hart Animal Hospital

The Dr. Hart Animal Hospital facility is a 5,500 square foot facility.

The facility includes waiting area, administrative offices, four exam rooms, 12 stall kennel, surgery suite, laboratory, pharmacy, and x-ray room with lead shielding.

The building is a single story wood framed structure with slab-on- grade floors. The kennel area received special 2 part epoxy coating on floors and vinyl exterior siding.

Site design required coordination with and approvals from Thornapple Township ordinances, Barry-Eaton County Health Department, State Health Department, Michigan Department of Transportation (MDOT) and State of Michigan Building Code for plan approval.

HVAC system provided for substantial odor control measures along with energy recovery unit to minimize energy consumption while providing effective odor control.

Edgewood Activity Center

Edgewood Village is a new 5,000 square foot community activity center. The project includes offices, kitchen, a conference room, computer room and multi-purpose areas. The project is LEED Silver certified.

Structural engineering for the building included structural steel frame with glulam beams, I-Joists, and Structural-Insulated-Panel roof and wall system. Concrete floors were exposed polished colored concrete.

Mechanical engineering included HVAC design of a split furnace system with energy recovery units and building energy management System controls with CO2 sensors for optimization of energy usage. Design also included plumbing design of domestic water, sanitary sewer and gas piping.

Electrical engineering included Interior power distribution design, Interior lighting design including branch circuiting and switching, Interior telephone and data processing system provisions including empty conduit and junction box locations site Lighting and PV system design

East Grand Rapids Community Complex

The East Grand Rapids Community Center project includes both renovation and expansion of the Library, City Hall, City Council Chambers, City Engineering, and Grounds Department. Two separate buildings were interconnected to expand the existing facilities.

The total project size is 52,000 square feet with a construction cost of $7.8 million. Portions of the facility remained in operation during the construction period.

This project received LEED Silver certification. Energy saving features include daylight harvesting to reduce lighting levels at the building perimeter and energy saving HVAC controls system featuring variable frequency drive fans. A new Building Automation System was provided to incorporate lighting, occupancy, and demand ventilation control for energy credits. The project required new electrical service and relocation of the existing emergency generator to accommodate the new addition. A snowmelt system was provided for the public sidewalks and entrances.

The existing buildings were supported on driven steel H-piles due to poor soil conditions. The new building additions were supported on 60 foot deep auger-cast-concrete piles with pile caps and grade beams.

Mahle Industries

The Mahle Industries equipment foundations encompassed designing two equipment foundations with extreme tolerances to deflection and soil vibration. The stringent conditions required soil analysis and vibration measurement to ensure the equipment was isolated from nearly all vibration. A heavy floating slab design was utilized to provide mass and ensure vibrations would not be transferred through the solid base foundation.

Another equipment foundation involved converting a manufacturer’s metric drawings and designing a foundation utilizing the standard system. Revit Structures was utilized to model the pocketed foundation, reinforcement, bar grating, baseplates, and anchors to deliver a coordinated model. Building the model beforehand flagged a dimensional discrepancy on the metric drawings.

Lighthouse Development

The project includes remodeling an early 1900’s two story wood framed building and a two story addition along the front. The total project size is 15,000 square feet with a construction cost of $2Million. The project received LEED certification.

Civil engineering included site design, layout, and a storm water management system that included new “porous pavement”. Close coordination with the City Planning Department was required to meet new City guidelines for stormwater system design.

Structural engineering included a new elevator shaft, stairs, and the new steel framed two story addition. Floors were reinforced to accommodate new higher live loads and new roof top equipment.

Mechanical engineering for the building included HVAC design of a split furnace system with Energy Recovery Units and Building Energy Management System controls with CO2 sensors for optimization of energy usage. Design also included plumbing design of domestic water, sanitary sewer and gas piping, and fire protection systems. Engineering also included performing energy model studies, life cycle cost analysis, and design provisions to meet the Michigan Energy Code and Michigan Building Code

Electrical engineering included interior power distribution and lighting design, and provisions for telephone and data processing systems. Site lighting design was also provided.

Frederik Meijer Gardens Amphitheater

Comprehensive Engineering’s involvement in the Fredrik Meijer Gardens Amphitheater project consisted of specialized structural engineering, centering on a custom bowstring truss with a 90 foot clear span. To allow for changes in length due to thermal expansion slide bearing connections were utilized. Structural items related to concrete included durable epoxy coated reinforcement and a special sand blast finish.

Genesis West Apartments

The Genesis West Apartments project focused on a new residential development located on a 3.5 acre parcel. The development includes 10 separate wood frame structures on cast in place concrete foundations, private road, parking facilities, public sanitary sewer and water main extensions, stormwater management system. Comprehensive Engineering completed structural and site design services, site plan approval submittals, permitting and coordination with municipalities and utility companies. The project designed for LEED for Homes Certification.

Structural engineering services included design of wood framed superstructures and cast-in- place concrete foundation systems. The superstructure incorporated engineered wood members for wall and floor construction.

Civil engineering involvement consisted of a full residential housing development from the schematic phase through construction monitoring. The public utility extension required municipality approval and MDEQ permitting. The project was funded under the Michigan State Housing Development Authority therefore the site was designed to provide handicap accessibility to all buildings and facilities on site. The barrier free accessibility affected the layout of parking and sidewalks to provide access according to code requirements and the overall site grading.
