Architecture & Engineering

I have led over 25 projects (>$50 MM) for various agencies in the public sector and managed the projects through all aspects of the lifecycle, from conceptual design through project completion. I planned, delegated, monitored and maintained control of all aspects of the projects, and ensured that all projects are delivered on time, within budget and according to the project's scope of work. I supervised a multi-disciplinary team of 5 engineers and coordinated work between all trades. I understood complex project needs, provided reliable options and delivered cost-effective & energy efficient design solutions in a timely manner. I was also responsible for relationship management with the project owners, architects and contractors.

In addition to designing Mechanical (HVAC equipment - including chillers/boilers, ductwork, hydronic piping, steam piping and HVAC controls) systems, I also designed Plumbing (domestic cold and hot water, plumbing piping, sanitary drainage and gas), Electrical (power, interior lighting, exterior lighting, data, telecommunication and distribution), Fire Alarm (smoke/CO/heat detectors, digital fire alarm systems and panels) and Fire Protection (sprinkler and fire piping) systems. Some other clients I worked with are School District of Philadelphia (SDP) and NJ DPMC. I worked on several new additions and major renovations at educational facilities, correctional facilities, multi-family residential, mixed-use and office buildings. I strongly believe in quality engineering and sustainable design and strive to improve people’s lives by engaging in inclusive design that connects our communities and sustains our environment.

I managed all projects by following the engineering design process, where I started by filnding and responding to proposals, preparing fee estimates and creating technical writeups. When the project was awarded to our firm, I performed field surveys to assess conditions existing of existing systems and prepared Scope Reports with Findings and Recommendations, Calcuations and Construction Cost Estimates. Next, I worked on interdisciplinary Design Drawings in AutoCAD, typed up the Product Specifications and performed Quality Control on construction documents to ensure consistency with the project goals and to reduce cost. Throughout the process, I worked closely with my clients and responded to any concerns by the review team. I regularly performed heating and cooling load calculations and building energy modeling to determine design criteria and size system components. I am well-versed with my clients' design requirements, room planning standards and filing procedures (DOB, BCC and FDNY). I ensured the Contract Documents adhered to the applicable state and national codes and regulations, such as IBC, IMC, IFGC, NYC Building Code, NYC Mechanical Code, NYC Energy Code, ASHRAE 90.1 and NFPA-13. Moreover, I answered any RFIs, reviewed shop drawings and submittals from the contractors, and issued addendums and bulletins as necessary. Lastly, I prepared final punchlists and invoiced for the work that has been completed.


Helping Students Return to School

NYC School Construction Authority

May 2020 - Apr 2021

As local and federal governments started looking for ways to reopen schools, it was clear that much more needed to be done to assure parents that their kids will be safe when they return to school. Over the summer, the NYC Department of Education held several engagement sessions with families to learn their concerns and provide updates on the steps the city has been taking to mainatin a healthy learning environment.

As an MEP Design Consultant, it was obvious to me that a properly maintained and operated heating, ventilation and air-conditioning (HVAC) system can reduce the spread of viruses. Alongside proper handwashing and social distancing, air filtration, humidity levels, percentage of outside air and air distribution are all key to improving productivity and health in indoor spaces.

In late August, Mayor Bill de Blasio and the NYC School Construction Authority (SCA) started forming Ventilation Action Teams (In the news: NY1, CBS and ABC) to ensure air flow in all student and staff spaces across each of the 1,700 schools in NYC. The goal of this project was to enable students and staff to return to schools in September 2020 by inspecting the existing Ventilation systems. Classrooms deemed unfit either had their issues addressed, or the spaces were taken offline until the systems were made functional.
As one of the Action Team members, I surveyed numerous schools across NYC, including New Dorp High School in Staten Island.

Making sense of the data:
Per the 2014 NYC Mechanical Code (Table 403.3), classrooms must bring in at least 10 CFM of outside air per person and at least 0.12 CFM of outside air per square-foot of space. Similarly, staff offices must bring in at least 5 CFM per person and 0.06 CFM per square-foot.
The old Mechanical Code (prior to 2008) allowed spaces with operable windows to be used for natural ventilation based on the index of ventilation. However, the new code (2008 and 2014) allows operable windows to be used for natural ventilation if the windows provide 4% openable area. If the thresholds to use natural window ventilation are not met, mechanical ventilation (exhaust fans) would have to be coupled with the operable windows.
For windowless buildings or rooms not located against the perimeter with openable windows, the ventilation would come from the mechanical supply system.
I'll leave you with the below excerpt from the code:
102.4.1 Minor additions, alterations, renovations and repairs to existing mechanical systems shall meet the provisions for new construction, unless such work is done in the same manner and arrangement as was in the existing system, is not hazardous and is approved.

The next phase of the project was to provide immediate recommendations to repair the ventilation systems and make long-term recommendations for future improvements. The teams prepared scope reports, construction cost estimates and detail design drawings to make the air handling systems operable either through reparation of defective parts or a complete replacement. As part of one of those teams, some examples of recommendations I made were airstream disinfection, increasing the amount of fresh air intake, selecting exhaust fans to maintain a negative air pressure in the room, and displacement ventilation (in which cooler air enters from below and lifts contaminants). Some non-HVAC recommendations were installing antimicrobial polymer surfaces or copper alloy surfaces which naturally kill viruses.
