On Day 30 of #PreservationMonth, TTG showcases the Tomochichi Federal Building and U.S. Courthouse in Savannah, GA. The Tradesmen Group was selected by GSA to make architectural repairs on the courthouse tower, improve structural stabilization, then restore the tower’s marble façade, clay tile roof and copper gutters. For the project, TTG collaborated closely with general contractor Brasfield & Gorrie, LLC, preservation architects Hartman-Cox Architects and engineering firms Wiss, Janney, Elstner Associates, Inc., RW Èngineering, Bennett Preservation Engineering PC and D.H. Charles Engineering, Inc. TTG and Universal Manufacturing Corp. installed extensive scaffolding over the existing tower, with special attention paid to protecting the roof and marble walls from impact of the scaffold system. Work is still underway on this active project. The Tomochichi Federal Building and U.S. Courthouse is an icon in the heart of Savannah’s historic district, and it is listed on the National Register of Historic Places. Built between 1894-1899 and enlarged three decades later, the original portion of the building is constructed entirely of white Georgia marble; it features Italianate tripartite facade divisions characteristic of its Second Renaissance Revival style. Congress named the federal courthouse after Yamacraw Indian Chief Tomochichi, who befriended English settler General James Edward Oglethorpe and assisted him in creating the English colony that later became Savannah. #SavingPlaces

🏛️ Exploring Ancient Reinforced Concrete Techniques in the Pantheon 🏗️ 🌍 The Pantheon in Rome stands as a testament to the ingenuity of ancient engineering. Dating back to 126 AD, this iconic structure utilized innovative construction methods that resemble the principles of reinforced concrete, albeit without modern materials. 📐With an internal diameter of 43.4 meters (142.3 feet), almost half the length of a football field, it is the largest dome ever built without single piece of steel in concrete. ⚽️ 🛠️ Materials Innovation: The dome of the Pantheon was crafted from a concrete mix incorporating pozzolana, a volcanic ash found locally, and lime. This mixture, while lacking steel reinforcement, demonstrated incredible strength and durability. 🏗️ Design Strategies: The construction of the dome integrated a gradation of materials, employing a lighter concrete mix at the top and progressively denser compositions lower down. This strategic use of varying densities helped distribute the weight of the dome effectively. 🧱 Reinforcement Techniques: Ingenious design included horizontal brick rings within the structure, acting as reinforcement elements. These rings provided crucial support, minimizing stress and enhancing the dome's stability. 🗝️ Innovative Hollow Spaces: The dome's construction incorporated hollow spaces and cavities, a remarkable feature reducing overall weight without compromising structural integrity—a true testament to ancient architects' foresight. 🌟 The Pantheon's construction methods, blending materials, thoughtful design, and strategic reinforcement, highlight ancient engineering brilliance in achieving durable structures without modern-day steel reinforcement techniques. 🏛️ Let's celebrate these ancient marvels that continue to inspire modern construction practices! What lessons do you think contemporary engineers can learn from such ancient structures?

"The 16th-century architects and builders who conceived of and constructed Saint Peter’s [Basilica] used scale models in wood or clay and hand-drawn patterns to guide their crews of workers and artisans. In 1514, when Raffaello Sanzio da Urbino, known commonly as Raphael, was named head architect, he added another dimension to the renderings, making drawings with three views: ground plan, elevation, and section. We can only guess at the wonder with which Raphael might behold the digital twin of today, a dynamic, data-dense model in three dimensions of unprecedented accuracy and detail. Fully navigable, it lets users zoom within millimeters on every aspect of the building’s architecture and art, inside and out, and all in proper scale and proportions. " https://lnkd.in/gq2Nvr6c

Preserving the American Heritage by documenting the as-built conditions of historic buildings. 3D Laser Scanning | Photogrammetry | 360 Tours | 3D Modeling | Deviation Analysis.
"...if you have to make a decision between saving 1740s masonry and 1920s concrete, go with the masonry." (Craig M. Bennett, Jr., PE) If you are passionate about the work and process of preserving historic structures, then I highly recommend Craig Bennett's article that discusses the intricate preservation and repair work on Drayton Hall, a notable example of Palladian architecture in America (link in the comments section). The case study highlights the challenges of maintaining historical integrity while implementing modern engineering solutions, focusing on the structural analysis and repairs of the building's masonry and foundations. #structuralengineering #historicpreservation #masonry #heritagebuildings

From vision to reality... Understanding the fundamentals to constructing a complex structure, such as the Houston Ismaili Centre has naturally led to structural optimisation both in terms of cost and carbon for this project. The Prayer Hall, a 34x34m clear-span space with the North Eivan residing over, consists of a framing scheme of seven rotated interlocking squares. By rotating the first square, the spans are reduced by 30% while the resulting bending forces are reduced by over 50% when comparing to traditional orthogonal framing. By prescribing that the North Eivan steel frame is constructed overtop before pouring the main concrete deck, ensures that additive deflections could be minimised and the large girders could be optimised in terms of cost and carbon. The Atrium structure consists of a series of concentric geometric shapes that decrease in size as the structure elevates from storey to storey. The steel vierendeel trusses ensure views down into the atrium, and the full erection of the steel truss system offered the best outcome in terms of additive deflections, saving significant cost and carbon before the concrete encasement and composite action that is achieved with the follow on concrete frame construction.

🌳 Introducing the 1st of April monument, a contemporary lookout tower in #Brielle, the Netherlands, representing the historical North Gate of the Bastion of Brielle in an abstract way. Designed by ro&Ad Architects, this timber lookout tower features a wooden structural grid that aligns with the historic brick foundation of the former North Gate of the Bastion. The structure incorporates traditional carpentry joints with a modern twist, utilizing digital fabrication methods for precision. GEOMETRIA rationalized and meticulously modelled the intricate structure and joints, ensuring precise digital fabrication and providing all the necessary data for on-site assembly. The fabrication modelling process created a precise timber 3D model with around 2000 unique pieces and 5000 joints. Each piece got its own code for easy identification, tracking its location from fabrication to construction. Summum Engineering provided structural engineering expertise and detailed joint specifications, influencing both the precise beam structure and the diverse implementation of joints in the 3D model. To optimize material usage, wood profile dimensions were adapted based on local structural loads.

Roman concrete, also known as opus caementicium, stands as a testament to the engineering prowess of ancient Rome. This remarkable building material played a crucial role in the construction of some of the most enduring structures of the Roman Empire, many of which still stand today. The secret to the longevity and strength of Roman concrete lies in its unique composition and innovative construction techniques. One of the key ingredients in Roman concrete was a volcanic ash called pozzolana, sourced primarily from the region around Mount Vesuvius. When mixed with lime and water, pozzolana created a chemical reaction that produced a durable and water-resistant binder. This binder, combined with aggregates such as rubble, stones, and bricks, formed a strong composite material that could withstand the test of time. The Romans also incorporated other additives into their concrete mixtures to enhance its properties. One such additive was seawater, which reacted with the lime to form additional minerals that reinforced the concrete and made it more resistant to erosion. This innovation allowed the Romans to build structures such as harbors, bridges, and aqueducts that could withstand the corrosive effects of seawater. The use of Roman concrete revolutionized construction techniques in the ancient world. Its exceptional durability and strength enabled the Romans to build massive structures that have endured for centuries. The Pantheon in Rome, with its iconic dome made of Roman concrete, is a prime example of the lasting legacy of this remarkable building material. In addition to its structural properties, Roman concrete also had aesthetic appeal. The Romans were able to mold and shape the concrete into intricate designs and patterns, allowing for the creation of visually stunning architectural masterpieces. The use of concrete in Roman architecture paved the way for the development of new building styles and techniques that would influence construction practices for centuries to come. Despite the advances made in modern concrete technology, Roman concrete continues to fascinate engineers and historians alike. Its longevity and resilience serve as a reminder of the ingenuity and skill of the ancient Romans. By studying the composition and construction techniques of Roman concrete, we can gain valuable insights into sustainable building practices and materials that may inform future innovations in the field of construction. Roman concrete stands as a remarkable achievement of ancient engineering and architecture. Its durability, strength, and versatility have left an indelible mark on the built environment of the Roman Empire and continue to inspire admiration and study to this day. #civilengineering #construction #engineering #creative

#construction #civilengineering #earthquakeengineering The basic form of traditional Japanese architecture is a wooden foundation or pillar resting on a “foundation stone”. The Japanese style of “Ishibatate” or “standing on the stones” traditional framing has been perfected over 2000 years of trial and error. It is a framing style that aims to create a building that is so in tune with nature that it rests in it rather than being a prominent figure apart from it. The surface of the stone used as the foundation is uneven. The processing technique to precisely fit the wood into this uneven stone is called “Hikari-tsuke”. This style does not attempt to withstand an earthquake, rather using wood’s greatest strength, flexibility, the building implores several major strategies to absorb and disperse an earthquake’s energy. A foundation of columns on stone not fastened to the ground by any means. This strategy allows the building to shift as one in an earthquake’s tremors. a raised sub-structure called stiffeners instead of a sill foundation laid flat on stone or concrete.

From #ideas & #drawings, to #construction, it has been a major challenge of all #architects in #history what to #create for #building for #humans. When we look at the ancient architectural drawings compared to modern drawings, it would be always interesting to see how precise it had been and they show all the setting out dimensions and curvatures! Architects used to work closely with the builders on site whose signature were imprinted on the actual stonework (not for memorial purposes but for salary reasons). Then, what are we looking for in order to be an architect of “Next level” after all these years? . #3dwow #architecture #library #history
