The project consisted of a new Emergency Department, Critical Care building and extensive renovation of the existing mechanical systems in additional areas of the hospital.  The expansions and renovations were completed over a three-year period. 

In the fall of 2004 the chilled water system in the hospital Boiler House was removed and had to be reinstalled and operational before the spring 2005 cooling season.  The new system included "upsizing" all of the piping and equipment for additional capacity to serve the new expansions. This included a new cooling tower and 500-ton capacity chiller. 

The 41,200 square feet of Emergency Department Expansion involved an addition to the lower level of the existing Emergency Department and an upper level expansion above the existing Emergency Department.  A new Mechanical Equipment Penthouse servicing the expansion included two new air-handling units and mechanical systems.  The existing Emergency Department was directly below much of the construction area and installations had to take place with no impact on patient care.

The new 74,000 square feet of Critical Care Unit and Neonatal Nursery expansion included three new air handlers, mechanical systems, and medical gas system.  The units had to be delivered to the site and slid into the new Mechanical Equipment Room before the opening in the side of the building was enclosed. 

The unique challenge of this project was that the project had to take place while working in and around a fully operational hospital.  Patient care was always to take precedence over construction activities.  This required careful planning of shutdowns and system start-ups to avoid any disruptions to patient care.  In the end no unexpected major disruptions to patient care or the hospital took place.  As of 2008 Holland Hospital now has a modernized hospital to service the entire Holland area. 

The project consisted of a major expansion for the Wyoming Clean Water Plant Aeration facilities

and also included rehabilitation of many existing facilities. The rehabilitation portion of the project had to be done while not interrupting operation of the facility. This required close coordination with the City of Wyoming when shutdowns and flow diversion took place.

The new Aeration facility included five 500 HP Multistage Centrifugal Blowers, two 60 HP Basin Drainage Pumps, fifteen Vertical Mixers, and 15,000 Fine Pore Aeration Heads. The process piping included cement lined ductile iron piping ranging in size from 4” to 36” in diameter weighing up to 5,500 lbs per section and steel aeration piping ranging in size from 16” to 30” in diameter. The process piping system included valves that ranged in size from 4” to 36” in diameter.

The new RAS/WAS building included twelve Centrifugal Pumps, Four Horizontal Chopper Pumps, and Four 90’ diameter Final Clarifiers. Interconnecting cement lined ductile iron piping ranging in size from 4” to 16” in diameter was also installed. The rehabilitation phase of the project included five Vertical End Suction Centrifugal Pumps, four 100’ diameter Primary Clarifiers Drives, and custom fabricated cement lined steel piping ranging in size from 20” to 48” in diameter. Additional capacity for the Ferric Chloride and Sodium Hypochlorite systems were also part of the work.

This project was the largest expansion and rehabilitation project that has been undertaken since the original facility was built. This expansion will process a larger volume of wastewater more efficiently. This results in cleaner water discharging into the Grand River. The City of Wyoming now has an efficient facility that can service the local community for years to come.

The Donald K. Shine Water Treatment Plant Expansion Phase 1A was the prelude to a major expansion of the Wyoming Water Treatment Plant scheduled to start in 2006. Two new, large diesel generators were housed in a new generator building built to accommodate up to four generators. These generators are of the 2,000-kilowatt class and are provided with a bulk fuel system and remote radiators. They have the capacity to run only a portion of the plant during a power outage. Another phase of the project included replacing two high service pumps with two new 2,000 horsepower pumps, new discharge valves and associated piping. These pumps weighed over 24,000 pounds each. A third phase involved replacing three of the existing low service pumps in the low service building with larger pumps and variable frequency drives. Also, two sluice gates were rehabilitated that were located thirty-five feet below the surface of Lake Michigan and couldn’t be exposed. A final phase included a new automation system for the existing water plant filters. Many of the vales were replaced and the remainder had new actuators installed on them. The existing valves are over thirty-five years old. Valve size ranged from 6 inch to 48 inch. This project involved many challenges including specialized rigging for heavy pieces of equipment and the replacement of valves and pumps while maintaining operation of the sole source of drinking water for the City of Wyoming and its wholesale customers.
