Elizabeth on 7th

Construction Starts on Elizabeth on 7th!

Groundbreaking has occurred for Elizabeth on 7th signaling the start of construction. This project will be a 4 story, 103,000 sq. feet, steel framed mixed use building with retail on the lowest level and 3 levels of office above.

Check out this article in the Charlotte Business Journal:

E+M Upgrades Atlanta’s Lab Space

E+M recently purchased and are in the process of refurbishing a Satec HVL tension and compression machine to upgrade the Atlanta Lab Space  testing capabilities.


This machine can produce up to 300,000 pounds of tension and compression force on a specimen and will allow E+M to perform our own testing on on a variety of materials.

Testing for the modulus of elasticity for different concrete mixes, verification of elongations on post tensioning strands and performing concrete compression tests up to 14,000 psi are just some of the capabilities.

We look forward to using this knowledge to improve our designs, make them more cost effective, and then be able to share that improvement and pass those savings on to our clients.

E+M Celebrates 10 Years!


This month Ellinwood + Machado celebrates 10 years of business.

What started with Brad and Rafael working on a folding table out of their homes has grown into 35 employees over 3 offices and still growing!

E+M would like to thank all of the clients; past, present, and future for all the continued support that has helped us grow to where we are now.

E+M would also like to thank the employees without whom we would not be able to accomplish everything that has been done in the past decade.   We look forward to the future and many more years to come!

Shaping the Future Generation of Engineers

E+M Shaping the Future Generation of Engineers!

On Thursday November 14th 2019, E+M was invited to continue shaping the future generation of engineers by  presenting on structural engineering at the Latin American Montessori Bilingual Public Charter Elementary School in Washington D.C.

To those outside of the construction industry, the subject of structural engineering is quite mysterious. Introducing your job to 4th and 5th graders has its own complexities. The goal of the presentation was to show these young students that they can understand and solve structural engineering problems even at their age and experience level. The challenge was to explain complexities using language and concepts that they were already familiar with.

The presentation consisted of images of buildings during construction, a short video of an ETABS model in motion, and a few sets of construction drawings to pass around. We discussed design considerations of gravity, lateral loads, and serviceability. And we discussed different building materials such as concrete, steel, wood and masonry. A comment and question portion of the presentation ensued. The questions were unlimited.

I was very surprised with how many important considerations were covered throughout the Q&A portion of the presentation. The first 30 questions whittled out what is the responsibility of the structural engineer relative to the rest of the design/build team. We had questions about contractors and sub contractors, owners, building uses, risk categories, forensics, fireproofing, fire walls, and fire safety, mechanical, electrical and plumbing systems, interior design considerations, offset structural columns, bearing wall stacking, construction practices, and geotechnical considerations. By the end of this Q&A, I surprisingly covered more detail than I ever thought I would have had the chance to explain. Admittedly, it was very fulfilling to have had the opportunity to communicate in great detail how the construction industry functioned as a whole. After the Q&A, we had to move on to the design example.

For the final portion of the presentation, we pulled open Revit, and modeled a wood beam supporting a floor system. The students were tasked with calculating the load on the beam using a worksheet which walked them through the process. The kids split up into smaller groups and I had the chance to walk around and help answer questions about the calculations. Once the students had the load on the beam calculated, we opened up design software and sized an LVL beam that could support the floor joists.

Figure 1: The Revit model in which students took part in laying out a wooden frame floor system supported by two 20’-0” long beams

Figure 2: The worksheet used to walk the students through calculating the load on the 20’-0” beam

The group of students in Ms. Maisie’s 4th and 5th grade class could not have been a better audience. They listened, asked so many questions, and were generally excited to hear about what goes into building design.

Overall, I think the young students understood that they could do this job. I have a good feeling that at least one engineer will emerge from this classroom in years to come!

The Indy

The Indy Construction Update

Check out these construction pictures from The Indy, a student housing project in Marietta, Georgia for Kennesaw State University!

The Indy is a 172 unit, 543 bed Type III wood framed project that wraps around a 6.5 story precast parking garage.  There are extensive retaining conditions on the site and several amenity spaces such as a rooftop lounge and 2 story interior spaces.

Star Metals Residences Construction Update

Check out these pictures of the Star Metals Residences construction progress from a recent site visit!

Star Metals Residences is a 10 story cold formed steel multi family project in West Midtown Atlanta.  The EcoSpan composite steel joist system is used for the floor framing bearing on cold formed steel walls, all above a single level of concrete podium.

120 Piedmont Nearing Completion

E+M ‘s 120 Piedmont project is nearing completion!

This 26 story, 467,125 sq. foot student housing tower in downtown Atlanta, Georgia is wrapping up construction in time for the fall semester at Georgia State University !

The structure is post tensioned flat plate concrete slabs supported on concrete columns.  There are several columns that transfer out at level 6.    Lateral loads are resisted by reinforced concrete shear walls.   The foundation system consisted of pile caps with 18″ diameter auger cast piles.   There is also an independent structural steel canopy to highlight the main entrance.

Check out a few pictures of the completed structure:
