< 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.

< Back to all projects CLAYVILLE PEAKING PLANT LOCATION: Vineland, NJ DESIGN START/COMPLETION: Spring 2014 – Spring 2015 SIZE & TECHNOLOGY: 64 MW Trent 60 Gas Turbine / Dilution Air SCR / Natural Gas Compression / Utility Sub-Station IN-SERVICE: Spring 2015 FIRM ROLE: Engineering Waldron was selected as the Engineer of Record for the design of a new peaking facility located adjacent to the Atlantic City Electric Clayville Substation in Vineland, NJ. With the success of the Waldron designed Howard Down Unit #11 project, Vineland Municipal Electric Utility chose to further increase capacity within their service territory. The option was exercised for the purchase of a second Trent 60, SC and natural gas compressor. Waldron developed a detailed design package around the Trent 60 engine and substation interconnection. In addition, Waldron supported VMEU in the selection and oversight of a general contractor to implement our design. The plant was in-service in the Fall of 2015.

< Back to all projects TUFTS UNIVERSITY COMMISSIONING LOCATION: Medford, MA SIZE & TECHNOLOGY: 4 MW Gas-fired recip. engine. 800-ton electric chiller 600-tons of hot water absorption chiller and pumps IN SERVICE: Winter 2018 FIRM ROLE: Owner’s Engineer Services, Cx Waldron Engineering was contracted to perform the commissioning services for the new Tufts Central Energy Plant. The plant consisted of a 4 MW gas-fired reciprocating engine, with 200 horsepower waste heat recovery boiler and 3x800 horsepower firetube boilers. The facility also included an 800-ton electric chiller and 600-ton hot water absorption chiller. Waldron, as the commissioning agent and systems trainer, coordinated new boiler/chiller plant startup while the existing plant was in operation, provided supplemental design and engineering during construction and commissioning, worked with vendors to correct equipment design oversight, and developed commissioning test procedures. The challenge of getting the new systems operational against the backdrop of a working plant required careful coordination, precise planning, and smooth execution of our commissioning plan. Tufts was able to get its system online and derive an economic benefit from its new cogeneration systems.
