“Carastro & Associates was selected to perform a study of the existing chiller plant. This study was conducted to determine the best chiller plant replacement strategy that would yield the most value for the College….Carastro & Associates was very competent and was able to work towards the goals of the College. They are committed to quality workmanship, timely completion, and excellent coordination on all of the College’s projects. I find Carastro & Associates to be very professional and accommodating on all projects.”

—Senior Project Engineer, Client Confidential (College)

“The design team at Carastro & Associates collectively outperform other design firms both in terms of depth of knowledge and expertise and equally as important, their commitment to upholding the moral integrity of the engineering profession.  Their most recent project is that of a chiller plant design serving a multi-building facility encompassing Class A office space, 4-star hotel, retail, two banks and an elite members only business club.  Their methodical approach and attention to detail resulted in an accurate and detailed set of plans and specifications for what I consider to be a very complex project.”

—Mark Brinson, Senior Chief Engineer, Jones Lang LaSalle

“Carastro & Associates is very responsive to the Owner’s budget and schedule.  They are exceptionally good at documenting existing conditions on renovation projects, to avoid costly change orders during construction.  They are very proactive in visiting the site during construction, and preparing complete, clear, field reports.

—Alice Sutton, School District of Hillsborough County

“I work with many engineering firms and Carastro & Associates is one of the easiest to work with. They are, of course, technically very competent but just as important, they are responsive to my schedules and my needs for information. Carastro has been extremely responsive to our needs for quick turn around on maintenance projects. I always get helpful advice and honest opinions when I need them. The basic attitude is one of getting the job done as quickly and economically as possible while maintaining the quality we want.”

— Walter Harwell, School District of Hillsborough County

“In preparation for the scheduled replacement of our two chillers, our Building and Grounds Committee decided that we would need the advice of a mechanical engineer to insure that the project went as smoothly as possible.  We asked the construction company we’ve used for several projects who they would recommend, and they didn’t hesitate to suggest George Stefanovici from Carastro & Associates, Inc.  George calculated the tonnage that our expanded campus would require, estimated our installation and energy costs, and recommended the most efficient energy systems.  Working with George on this project has been a pleasure and we would definitely recommend Carastro & Associates to anyone needing engineering services.”

— Mike Circle, Facilities Director, Tampa Preparatory School

BayCare Health System has utilized Carastro & Assoc. on numerous projects, some as technical as a Data Center new-construction project, New Generator Commissioning, as well as some not-so-technical projects, such as adding new AC units to server rooms, or MDF room assessments. Many of our hospitals have also utilized Carastro & Associates for their engineering needs too. The expertise of Carastro & team was always on display for every project I have been a part of, as Paul’s engineering team is creative, well-versed, and well-educated. The Carastro team always participates in our project meetings, making themselves available to answer any and all questions asked.  They have a good working relationship with the other vendors, electricians, and construction companies. The Carastro team has even accompanied us out of state to perform acceptance testing on some of our newly manufactured IT gear. I highly recommend Carastro & Associates for their engineering expertise, and will continue to utilize the Carastro team as my company continues to grow as well.

–  Mike Jones, BayCare Health System

Carastro has worked on a multitude of projects for us and we have always been very pleased with the results. Most of these projects have been in critical facilities where extreme attention to detail is a must. There can be no downtime whatsoever. These projects, to name a few, have ranged from central cooling plant installations, UPS system installations, data center space remodels, as well as generator fuel system replacements. All [of] these projects have utilized excellent designs, gone smoothly, have been completed on time and within stated budgets.”

Carastro & Associates have provided design services for Chugach on numerous projects at MacDill AFB over the past 10 year period. They continue to be used and recommended due to their high quality of work and their level of support beyond the standard contract scope. In past projects, Carastro provided design, CAD, and administrative support. Their work was consistently excellent primarily due to the retention of their experienced staff. I would recommend them for any level of mechanical, electrical, plumbing, and fire protection design.
