Key Projects and Achievements

Holder Construction

Actapio Phase 2 Data Center Upgrade

The project was a buildout of the original Phase 1 construction of a 100,000 square foot data center with 2-megawatt critical load. Phase 2 added another 2 megawatts of critical load capacity. I was responsible for procurement of all the electrical and mechanical equipment for this expansion including two (2) 1 megawatt Mitsubishi UPS systems and batteries, eight (8) 300kVA PDUs & STSs, one (1) 600A medium voltage switchgear, and six (6) 65,000 CFM DEC cooling units totaling $6,000,000 in equipment costs

Denver International Airport Concourse B and C Expansion

The project was an expansion of the existing Denver airport concourse. My responsibility was to get bids from multiple special systems contractors to provide all MUFIDS, FIDs, structured cabling and DAS. Assisted with design input and ultimately awarded contract totaling $14,000,000.

Salt Lake City International Airport South Concourse East Expansion

The project was a complete redesign of the existing Salt Lake City International Airport. I worked with multiple electrical and low voltage contractors to successfully procure all the electrical and special systems scope for this expansion for a total of $34,000,000 for the electrical trade and $23,000,000 for the special systems trade.

Infinite Energy Center Expansion & Renovation

The Infinite Energy Center is a multipurpose entertainment facility located in Gwinnett County Georgia. This project involved doubling the existing convention spaces from 50,000 to 100,000 square feet as well as renovation to the existing forum and theater spaces. Worked to procure the mechanical, electrical and Building Automation Systems for the expansion and renovation work. These trades totaled $12,000,000 (mechanical), $11,500,00 (electrical) and $600,000 (BAS).

Iron Mountain VA2B2

The project was the second phase expansion of the Iron Mountain Data Center in Manassas, Virginia. I worked to procure the electrical, mechanical and Building Automation System for the Iron Mountain Virginia Co-location Data Center. Negotiated Team Approach Contracts for all three (3) trades totaling $48,600,000.

Agnes Scott Main Hall Renovation

Main Hall is the oldest existing building on the Agnes Scott College Campus having been constructed in 1891. This project involved complete replacement of the entire existing mechanical, electrical and fire protection systems. Worked with subcontractors for all three (3) trades along with the design team to provide the best solutions for these systems that would not compromise the unique architecture of this historic building. Ultimately I awarded theses trades totaling $2,600,000 (electrical), $2,400,00 (mechanical) and $125,000 (fire protection).

United Parcel Service Windward Data Center

Cooling Tower Fans VFD Upgrade

Replacement of six (6) 22-year-old two speed Baldor cooling tower fan motors and 90-degree gearboxes with six (6) Reliance DirecDrive VFD systems. Designed six (6) new NEMA 4X enclosures to house all six (6) ABB 880 Variable Frequency Drives on top of each cooling tower. Total power consumption of the cooling tower fans was reduced by 160,000 kWh annually.

UPS ME/BCP Battery System Replacement

The UPS ME/BCP batteries were 2003 vintage and had reached EOSL by 2016. This UPS system had four (4) battery strings with a total of 240 cells. These batteries were rated at 15 minutes. After examining the current loads and expected load growth, it was decided to replace these batteries with smaller FLA batteries with 7-minute capacity at full load. The current load per battery string is 150 kW. Under this load, the capacity of the batteries jumps to 116 minutes. Replacing the old batteries with new FLA 7-minute batteries as opposed to 15 minutes batteries reduced the project cost from $1,300,000 to $950,000 without compromising the reliability of Windward’s ME/BCP UPS battery system.

Security Gates and Fencing Upgrade

Design and installation of new security gate systems at both the front and rear employee parking lots, related to recommendations from UPS Corporate Security and the U.S. Department of Homeland Security. This included new dual swing gates at ingress and egress of the front parking lot to create a "Sally Port" vehicle control system. Rear parking lot slide gate was replaced by new high speed cantilever slide gate, reducing open/close cycle times by 50%. In addition, new 8' chain link and barbed wire fencing was installed around entire perimeter of the Data Center.

Static Transfer Switch (STS) Replacement

Replacement of thirty four (34) L3 & Magnatech Static Transfer Switches with new Liebert STS2 Static Transfer Switches. STSs were originally installed in 1994 and had reached EOSL. The challenge in this replacement was to maintain 100% operation of the corresponding Power Distribution Units that feed all critical loads at the data center. Coordinated and supervised all isolation and restoration activities with UPS Facilities Management Team & Cleveland Electric project crew. These efforts contributed to a seamless replacement of the Static Transfer Switches with zero loss of electrical power to all critical loads.

Cooling Towers Condenser Water Motors Replacement

Replacement of six (6) 86 hp condenser motors with new 75 hp condenser motors. The original 86 hp motors were custom wound in 1995 for the data center. When a motor failed, a new replacement motor required 5 months lead time for the motor to be custom manufactured. These motors were replaced with “off the shelf" standard high efficiency 75 hp motors which have a one (1) week lead time for replacement (at 1/3 the cost of the custom 86 hp model).

Water Treatment System Injection Header Upgrade

The original water treatment injection header for the chilled and condenser water systems was installed circa 1999 was very susceptible to calcium carbonate deposition along the interior piping which resulted recurring loss of flow. This was due to several factors including pipe sizing, injection location and chemical injection pump limitations. The new system utilized larger CPVC lines along with clear plastic viewing sections to allow facilities staff to access deteriorating conditions in the piping before they reached a critical point. Additionally, new, more efficient chemical injection pumps and improved injection design resulted in a chemical injection system that reduced maintenance cost by $12,500 annually.

Plate Heat Exchanger Expansion

The original plate heat exchanger was installed at the Windward Data Center in 2000 and contained 177 plates for a maximum cooling capacity of 1,200 tons. This provided "free cooling" to the data center critical loads for about 5 months of the year. By expanding the number of plates from 177 to 215, the cooling capacity was increased to over 2,000 and extended the cooling window of the PHE from five (5) to seven (7) months. This expansion, in conjunction with better controls, blending loop and the use of the thermal storage tank reduced cooling costs by more than $25,000 annually.
