< Back to all projects YALE UNIVERSITY INVESTMENT GRADE STUDY LOCATION: New Haven, CT STUDY DATE: November 2011 FIRM ROLE: Investment Grade Study for Repowering the Central Utility Plant Waldron was selected by Yale University to develop a master plan for the repowering of the existing Central Utility Plant. The existing facility consists of three 5 MW gas turbines and heat recovery boilers that provide steam and electricity to the campus. The turbines are now at the end of their useful life. Waldron’s scope included the development of a Basis of Design document that quantified the future requirements for the Central Utility Plant. The requirements comprised thermal and electric load profiles, operational restraints, environmental requirements, and economic parameters. An operations model of the existing Central Utility Plant was developed to simulate the hourly operations of the plant serving the campus loads for a 20-year period, BAU case (Business as Usual). A series of alternatives were developed and run against the 20-year simulation to quantify the technical performance of the options operating against the campus loads. An economic model of the operations is linked to the simulation, taking into account utility rate structures, commodity costs, and other influences. The combined models provided a data set that was utilized for the selection of a preferred option to be refined in to an investment grade business case. The investment grade business case included a detailed construction cost estimate, linked to a construction plan, including rigging analysis and a phasing-in schedule. Detailed operating cost results were included from the 20-year simulation. Operations costs and maintenance costs were developed down to the individual staffing level, consumable consumptions, and LTSA quotations. A final set of project economics along with a probabilistic analysis was developed for presentation for the business case to the trustees.

< Back to all projects BRIGHAM & WOMEN’S HOSPITAL MICROGRID DESIGN START/COMPLETION: February 2013 – July 2014 SIZE & TECHNOLOGY: 4 MW Reciprocating Engine Generator, 125 psig Waste Heat Boiler, Jacket Water Heat Recovery, (2) 700 BHP Firetube Boilers IN-SERVICE: Summer 2016 FIRM ROLE: Feasibility Study, Schematic Design, Design Development, Detailed Design Waldron Engineering & Construction, Inc. performed an initial feasibility study for Brigham and Women’s Hospital (BWH) to evaluate the feasibility and economic value of installing a Combined Heat and Power Plant (CHP) in their new Brigham’s Building for the Future (BBF). The primary purpose for the CHP was to provide operational cost savings to the hospital and a level of resiliency to serve the energy needs of the facility. In addition to studying various CHP technologies, including combustion turbine generator and reciprocating engine generators, Waldron appraised the value of supplying electrical and thermal energy not only to the new BBF building, but also to the neighboring Shapiro building which is part of the Brigham and Women’s Hospital campus. Upon identifying that a 4 MW reciprocating engine based CHP was the optimal size and technology to serve the two buildings, Waldron executed the detailed design of the entire central energy plant. Waldron served as the engineer of record for the project which included a 4 MW recip-engine based CHP plant with dual fuel firetube boilers that were installed in the basement of Brigham & Women’s Hospital Building for the Future in Boston.

< Back to all projects P&G GILLETTE WORLD HEADQUARTERS CHP LOCATION: Boston, MA DESIGN START: Winter 2009 DESIGN COMPLETION: Summer 2010 SIZE & TECHNOLOGY: 7.5 MW Taurus 70 with HRSG & SCR FIRM ROLE: Engineering, Procure, Construction Management and Commissioning IN-SERVICE: Summer 2011 Waldron was selected by P&G Gillette to expand their existing power plant by installing a new combined heat and power plant in a location that was occupied by an existing boiler. A multi-level plant design was developed with the prime mover selected as the 7.5 MW Solar Taurus 70 gas turbine that exhausted through a 100kph Rentech HRSG. Waldron was also awarded the construction management (CM) and procurement contract for the plant installation. Except for the turbine, gas compressor, and HRSG; Waldron supplied all plant auxiliary equipment and subcontracts to execute the plant installation. The CM scope included site work, soil remediation, driven piles, concrete foundations, demolition of existing plant interferences and boiler, abatement, structural steel installation, major & auxiliary equipment installation, piping & insulation, aqueous ammonia tank, fire suppression, fire alarm, architectural finishes, electrical distribution, and instrumentation and controls. In addition, Waldron performed the start-up & commissioning of the plant. Throughout the project there was continued added scope due to unforeseen conditions with an expectation of zero changes to the schedule. Waldron also had changing utility interconnect requirements which led to impacts on the design. In addition, Waldron successfully navigated Boston permitting changes during the certification of occupancy process. Waldron’s work on Gillette proved to be very challenging. After many curveballs, we met those challenges successfully. For example, Waldron had to perform the demolition and erect structural steel inside the operating plant—a plant that could not have any unplanned outages. We also had to be creative in planning and executing construction operations during severe weather conditions in order to make a large cut in the existing building envelope during the winter months in Boston. Existing sensitive equipment and systems installed in the construction path had to be protected from construction activities. As a scheduling challenge, Waldron had to coordinate weekend fire alarm testing and the permit closeout process between the vendors, the subcontractors, the Boston Fire Department and P&G – which in and of itself is no small task. It is worthy to remember that the plant had to stay operational at all times to support the manufacturing of P&G Gillette products. Waldron and our subcontractors planned and worked many major holiday weekends to suit the few plant planned outage schedules. Waldron worked closely with the client and building owner during the commissioning process to overcome impacts to the newly installed equipment from utility harmonics.
