The CHP will include on-site electric generation and recovery of waste heat in the generation of electricity to heat and cool campus buildings. The single most important driver for the study, other than its economic feasibility, was to determine if CHP offers a cost effective and reliable means to significantly reduce the University’s GHG emissions thru the recovery of waste heat and reduction of fossil fuel burning, in indirect purchased electricity and onsite usage, to meet the Morningside Campus’s energy needs. The project team considered a wide range of CHP technologies and configurations to be sited at the existing steam & chiller plants below the Center for Engineering and Physical Science Research (CEPSR). The CHP technologies investigated included: combustion turbines, fuel cells, reciprocating engines, and steam turbines in configurations sized up to about 14.5 MW. Waldron was selected to execute the detailed design for the project.

In turn, the result is a well-defined, successful project. OUR PROCESS Important steps in the engineering and design services process include: PROJECT DEVELOPMENT The project development process can be a tortuous path through a maze of regulatory, contractual and financial barriers. Navigating this gauntlet successfully requires knowledge of the ways in which facility performance, technical constraints, and regulatory obligations coincide. Our direct experience bringing energy facilities from concept to operation enables us to optimize the path for you without sacrificing key outcomes. DETAILED ENGINEERING & DESIGN Waldron’s detailed engineering and design process is an orchestrated flow of information that proceeds from a comprehensive understanding of stakeholder goals to a set of plans and specifications that is specific to the project’s needs. We take a “no more and no less than is needed” approach: our multi-discipline in-house coordination process emphasizes comprehensive drawing sets with little to no delegated design, while our specifications are pared down to those requirements both specific to and essential to the project. The result is a design package truly ready for bidding and construction, which minimizes change orders and project delays by providing the clear direction that is required for an efficient construction process. CONSTRUCTION ADMINISTRATION Every construction project presents unique challenges. The key to success is working proactively with the vendors and trade subcontractors to navigate those challenges in a timely and cost-effective manner on behalf of the Owner. Waldron emphasizes productive relationships with all stakeholders, and adopts a responsive, flexible approach to overcoming obstacles and keeping the project on track. Because the starting point is a comprehensive, fully-coordinated design, our teams have the ability to quickly identify the impacts of design decisions on all project disciplines and resolve field challenges practically and efficiently.
