C&S Introduces ACE Students to Facility Design

This past January, a local client reached out to C&S’s Orlando staff needing assistance in preparing a presentation on MEP building systems for a group of Central Florida high school students. The students are part of the ACE Mentor Program, which helps educate high school students on careers available in the A/E/C industry. Each year, groups of students select a project type, come up with project ideas (such as renovating their school for COVID safety), and then apply cost estimation, architectural design boards, and more in preparation for a national competition. Matt McQuinn and Bryn Currie stepped in to teach the students about MEP systems, their importance to facility design, and helped guide their project design considerations. Matt has continued to tune-in to the ACE meetings and provide support with his expertise.

The ACE Mentor Program not only aims to enlighten high school students to pursue careers in the architecture, engineering, and construction industry but seeks to help build a diverse, better-prepared workforce, prioritizes the engagement of underrepresented communities in the industry, and guides students by providing scholarships, internships and mentoring towards an A/E/C career path. C&S’s Philadelphia office is also assisting its local ACE Mentor Program affiliate through financial support.

C&S is deeply committed to education, particularly the science, technology, engineering, and math fields. We believe that STEM/STEAM education is vital to the future of our company and community, and we are proud to support a number of initiatives to build a strong pipeline of students capable of tackling our community’s future challenges. Last year, C&S’s Syracuse office hosted over 50 students for a day of hands-on learning. Watch the video here.

C&S is proud to support the ACE Mentor Program of America and would like to thank ACE for the work it does in our communities!

Jarrod was born in Winter Park, Florida and grew up in the Orlando area. He attended the University of North Florida for one year following high school and, after exploring several different industries, his mind kept returning to architecture. Jarrod received his Bachelor’s degree in Design from the University of Central Florida and obtained his Master of Architecture degree from the University of Florida. He was hired by Rick Swisher Architect, Inc. and followed the company into its merger with C&S. He is proud of his job at C&S and is passionate about learning in order to help the architecture department grow into a design-oriented entity. He enjoys a variety of activities including traveling and learning about other cultures, hiking, biking, kayaking, canyoneering, boat trips, museums, theater, and is game for just about anything!

Question & Answer with Jarrod Lopatka

BIM Building ModelImproving BIM Practices from the Group Up

While building information modeling (BIM) often plays such a large part in day-to-day design and construction operations, it can quickly fall to the wayside to other areas of focus. An overhaul of existing BIM practices can seem like a daunting task, but one that is well worth the effort. C&S’s Peter Rowan discusses ideas for improving BIM practices from the ground up.

Tampa International Airport Monorail System Decommissioning and Moving Walkway Installation

As Tampa International Airport continues to grow and enhance its experience, design is underway to improve passenger convenience in the long- and short-term parking garages. C&S is performing engineering design that will include full decommissioning and demolition of the existing monorail & track system between the garages, accompanied by the addition of new moving walkways on Level 4 of the long-term parking garage. Currently, passengers have a path of travel of up to 1,000 feet to the terminal building foot bridge once on Level 4 of the expansive garage. The new walkways will flow to and from the terminal along the path of the existing elevator banks. On Level 7, the existing monorail connection to the short-term garage will be modified for egress and expanded foot traffic access. Through this effort, a goal to also afford more parking spaces to both garages will come to fruition.  

C&S is providing structural and electrical engineering design services along with architecture and wayfinding in a progressive design-build delivery with Manhattan Construction.

Louver Sizing

Mechanical Louver Sizing

Need to estimate an outdoor air intake mechanical louver size before an engineer is on board? The following estimation approach can prove helpful for getting sizes, especially if they will factor into the building aesthetic.

Determine Ventilation Rates

LouverVentilation rates are dictated by the mechanical code and can range from simple to complex, depending on the system types used. However, this rule of thumb could help you get in the ballpark of providing a placeholder louver size within your conceptual designs.

To find the required ventilation rates, head over to the Florida Mechanical Code, Table 403.3.1.1. You will find than an office occupancy for buildings with enclosed offices or cubicles is 5 persons/1000 sqft (maybe safer to assume 100 sqft/ person if using smaller offices) and the ventilation required is 5 CFM per person and 0.06 CFM/sqft of facility. A data entry/telephone space usage typically is a denser occupancy with fewer sqft/persons and the code recommends 30 people/1000sqft. If you know the expected occupant count, us that number instead. As engineers, we’ll apply these calculations space by space, but for estimating purposes, applying to the overall building area is a good start.

For a 10,000 sqft call center, we would use the information above to estimate that there are 300 occupants. The CFM/person is 5 and the CFM/sqft is 0.06. Using 300 people and 10,000 sqft, we get a ventilation rate of 2100 cfm.

Size the Louvers

For louver sizing, we limit the intake air speed to 500 ft/min. Newer louvers can handle intake airspeeds up to 1000 ft/min without bringing in much wind-driven rain, but 500 ft/min is a conservative estimate and provides less pressure drop. For our example 2100 CFM at 500 ft/min will require a louver free area size of 4.2 sqft. Hurricane rated louvers tend to be only about 50% free area compared to the overall area of the louver, so the actual louver face size will be twice the size of the free area, or 8.4 sqft.

CFM = cubic feet per minute
sqft = square-feet
ft/min = feet per minute
