JAMAR IS WORKING ON ST. MARY'S DULUTH CLINIC EXPANSION

The Jamar Company is currently working on St. Mary's Duluth Clinic new 250,000 square foot cancer center. This expansion project is a registered LEED project and is considering pursuit of SILVER certification.

M.A. Mortenson of Minneapolis, MN is the construction manager for this facility which has a total construction budget of $51 million of which $12 million represents work secured by the Jamar Commercial Mechanical Division and $1.8 million in work secured by the Jamar Architectural Division.

LEED, or Leadership in Energy and Environmental Design, was created to define “green building” by establishing a common standard of measurement; promoting integrated, whole-building design practices; recognizing environmental leadership in the building industry and raising consumer awareness of green building benefits.

The Weidt Group has performed the building modeling, incorporating several energy saving solutions as part of Jamar’s value engineering process, helping this project to earn the LEED classification. Energy saving solutions include; working with water reduction and efficiency; chemical free water treatment system; installing high efficiency variable frequency drive motors; increased boiler and chiller efficiencies; CO2 monitoring and control of outside air.

Jamar has just completed 18 months of MEP pre construction as part of its design/assist mechanical scope. AutoCAD and QuickPen 3D software were used for the MEP coordination drawings. Currently, Jamar crews are working on plumbing, HVAC piping and ductwork, roofing, siding and waterproofing systems. Completion is scheduled for March 2006 with 34,000 of 97,000 estimated man-hours worked to date.
Mechanical system highlights include:

• Two 200 HP low pressure steam boilers with fuel oil back-up.
• 820 ton variable primary cooling loop with one Trane centrifugal chiller and one induced draft, cross flow cooling tower both utilizing variable frequency drives.
• Dolphin chemical free water treatment system for HVAC condenser water.
• Variable air volume air distribution system utilizing five custom double wall air handlers with over 200,000 CFM in all.
• Medical gas system including oxygen, medical air and vacuum.
• 20,000 linear feet of snow melt tubing.
• Medical chillers with emergency backup for three MRIs, two CRTs and two linear accelerators.
• Johnson Controls direct digital control/energy management system including lighting controls.

Architectural system highlights include:

• 35,000 sqft. below grade foundation waterproofing.
• 8000 sqft. hot applied terrace waterproofing including a high grade terrace paver system.
• 9000 sqft. in traffic coatings.
• 786,000 sqft. ballasted and fully adhered EPDM systems.
• 3000 sqft. high performance architectural louvers.
• 2500 sqft. aluminum plate column, soffit and skywalk panels.
• 10,000 sqft. field assembled metal wall panel systems.
• 2100 sqft. field assembled soffit panel systems.

The Architectural Division has been tasked with providing all the necessary AutoCAD coordination drawings and computerized estimating for the various components.

It was a major undertaking blasting the ledge work to accommodate underground installation of the HVAC cooling water pipe by Jamar and the electrical conduit by APi Electric.

A number of APi Group companies are working together to deliver the overall mechanical work scope:

• Viking Automatic Sprinkler will install a wet/dry sprinkler system complete with six (6) double-interlock pre-action systems and a 200-HP fire pump.
• APi Supply/ASDCO is supplying man-lifts and temporary heat.
• APi Electric will perform electrical and low voltage work.
• Lejune Steel is providing building structural steel.
