  • Cost, Time and Quality | The Golden Triangle in Construction

    Project Failure (Cost, Time and Quality) In all developed projects, a balance between cost and value must be established (CIOB, 2014) . The nature of the project would be influential in determining the prioritised objective of time , cost or quality /performance. As outlined in the publication by the Society of Construction Law (CIOB, 2014) , the most common causes that result in a project failure, where the lack of clear links between the project and the client’s organisation key strategic priorities with a misunderstanding on the agreed measures of success were the causes of projects not achieving the promised deliverables. Recent researched into major projects by (Dalton, 2008) as shown in Table 1 found that 75-80% of the causes of projects failing were due to procurement, the definition of project requirements and the client’s management capabilities. Table 1 - Top 10 risk sources of infrastructure projects failure (Dalton, 2008) Procurement Models

  • Green Hydrogen current and projected production costs

    Determining the Cost of Green Hydrogen Studies have found that there is significant variation in the cost of electrolyzer systems, ranging from USD 306/kW up to USD 4,748/kW . Thus, demonstrating the challenge of finding representative numbers for capital and operation costs of electrolyzers (Saba, et al., 2020). As such, these costs are determined based on the combination of projected overall costs of green hydrogen along with the estimated cost breakdown of electricity costs, CAPEX, and OPEX. Work by Jeffers, et al. (2021) shows cost breakdown estimates for green hydrogen in 2020 and 2050, as tabulated in Table 1. Using these values, the cost breakdown percentiles of green hydrogen in 2030 and 2040 can also be determined through extrapolation. The cost breakdown for each decade is presented in Figure 1.

  • Cost-Effective Materials That Don't Compromise Safety

    In most cases, cost is directly correlated to safety. Automobiles with the latest safety features. Nursery items with high-tech child protection. Organic foods that aren’t farmed with harmful pesticides.  Consumers will undoubtedly pay more for these items.  In the construction industry, however, cost does not always equate to quality, especially in the realm of safety. In many cases, there are more affordable options that are just as safe as their pricier counterparts. With this in mind, keep reading as we explore some cost-effective materials used in construction that don’t scrimp on safety. Composite Roofing Shingles Modern roofs face many threats to their safety. Fire. Extreme winds. Mold buildup. Unfortunately, many of the most durable roofing products have traditionally been among the most expensive. For example, slate, which is largely considered one of the most robust roofing options, can cost upwards of $30 per square foot. Much of this cost is due to the fact that slate is very heavy, requiring specialized machinery and skilled contractors for proper installation. It may also require additional weight-bearing capacity than cheaper roofing, limiting the types of structures on which it can be used. To help ensure slate-level durability at a fraction of a cost, modern buildings are turning to innovative composite shingles. Fabricated from a mixture of asphalt, fiberglass, and recycled polymers, synthetic shingles are lightweight and easy to work with, making them suitable for all types of roofing substrates and installation by any roofing professional.  In addition to being among the leaders in mold resistant shingles , composite roofing also offers the highest fire, wind, and impact resistance on the market, offering premier ongoing protection for the structure. Also Read: Smart Materials: Shaping the Future of Adaptive Architecture Innovative Materials in Modern Construction: A Deep Dive Reclaimed Wood Not only is reclaimed wood less expensive than freshly-harvested timber, but it is the more environmentally-friendly option as it cuts down on energy usage and deforestation concerns.  It is great for furniture, deck railing, and shiplap accent walls. It can even be a flooring option for homeowners that want a rustic, weathered look. While reclaimed wood shouldn’t be used for framing or any other type of load-bearing application, it performs just as well as fresh timber for surface-level uses at a fraction of the cost. Permeable Gravel Driveways Concrete driveways are undoubtedly the most popular in suburban America. Their upfront cost is highly palatable. They also offer stunning aesthetics when new. With that said, time is not kind to concrete driveways. Moisture running off the surface leads to erosion that damages the substrate and surrounding landscape. This can cause buckling that is difficult and costly to repair. In addition, freezing conditions not only make concrete surfaces dangerous, but they lead to cracks that grow over time. If left unattended, they can turn into full-scale potholes that threaten vehicle and resident safety.  As a result, more and more homes are turning to permeable gravel driveways. This innovative system uses a series of heavy duty pavers  in the substrate which hold surface aggregate in place. This eliminates the shifting inherent to standard gravel driveways. Although a permeable gravel driveway may cost a bit more upfront than a standard concrete option, the elite drainage, ongoing aesthetics, and slip-resistant surface make them a great investment that will almost assuredly lead to lower lifetime costs through reduced maintenance and lower accident risk. Stone Veneer Stone veneer offers the same rustic charm as standard brick or other masonry surfaces without the hefty price tag. It is a thin layer of natural or engineered stone that is placed over wood, masonry, or concrete. Deployable for both interior and exterior walls, it is lighter weight and easier to maintain than traditional stone, making it the better choice for long-term cost savings, safety, and aesthetics. Cable Railings Cable railings are a trending option in all types of modern buildings. Not only are they great for rooftop decks thanks to their low profile for unencumbered views, but they are a sleek, stylish choice for stairways, balconies, and lofts in buildings that want to maximize a minimalist aesthetic.  Due to their thin nature, many people may be wondering: are cable railings as safe as more robust steel and glass options?   Yes . When properly installed, cable railings offer the same level of safety as other materials at a lower cost. There are just a couple of points to keep in mind. The cables must be taut enough to prevent a 4-inch sphere from passing through. This eliminates the threat of large falling objects and children getting their heads stuck. In addition, it is crucial to choose the appropriate railing mount . For cable railings, surface-mount posts connected directly to the deck or stair tread offer the best balance of cost and durability. Bamboo Bamboo makes it onto many lists of trendy building products. It is basically a grass that functions as a hardwood. This makes it highly sustainable because it can be grown on small lots and in a fraction of the time as timber. This helps keep costs under control . Often interchangeable with hardwood, bamboo can be used for furniture, flooring, internal walls, and a wide range of other applications.  Trim the Budget Without Compromising Safety with Innovative Materials In the construction industry, cost is not a universal indicator of safety. From composite roofing to bamboo flooring, consider any of the cost-effective materials listed above that do not sacrifice on safety.

  • Noise Control in Structural Design: Building for Acoustics

    Bustling neighborhoods, noisy apartment complexes, and clamorous industrial facilities have long been the bane of peace and productivity in communities. Fast forward to 2025, when buildings are becoming increasingly multi-use, and the need for sound control is greater than ever. Fortunately, there are a number of innovative materials and techniques that can assist in soundproofing from the very beginning of the construction plans. Keep reading as we explore some of the best ways to build for acoustics in structural design. Start with the Framing Choosing the correct framing material is one of the fundamental means of creating a quiet building. Air can move through small cracks in structural wood panels. This can cause small vibrations that allow noise to pass through the walls. Metal beams can also transmit exterior noise from weather and projectile impact without the proper insulation.  When framing for sound control, many builders consider concrete block walls. While they do a solid job of reflecting sound waves, they too need to be well-insulated to achieve premium soundproofing. Rather than spend a lot of time determining how to insulate block walls , it is worthwhile to explore insulated concrete forms (ICF).  This innovative framing system uses a series of precast insulated foam blocks that are locked in place at the construction site and set with concrete. The result is an airtight, double-insulation layer that gives the building the highest level of thermal and noise insulation on the market. Seal the Windows Not only do leaky windows kill energy efficiency, but they allow exterior noise to enter the structure. This can be quite problematic in bustling urban areas or regions that experience strong winds and/or heavy precipitation. Therefore, go the extra mile when choosing sealant for the window frames. Special acoustic caulk is designed for increased flexibility that can more effectively limit sound transmission than traditional silicone caulk, which can harden and crack over time. Optimize the HVAC System A building’s HVAC system has to do a lot of work. The fans and motors required to move large quantities of air can create quite the hum. Increased airflow during times of extreme temperature, leaks in the ductwork, and incorrect duct sizing can add to the din. This will create a distraction for all building occupants, reducing comfort and productivity.  There are several tips to optimize the system for HVAC noise reduction . A few of the most effective include: Seal leaks - a logical first place to start, patching leaks in the ductwork can keep air moving through the appropriate channels, creating a quieter, more efficient system. Reduce inlet noise - acoustical louvers can strip noise from the ambient air as it is sucked into the HVAC system. Balance air flow - it is crucial to have the correct amount of air flowing through the ductwork. Too much can create additional noise by putting the pipes under strain. Volume dampers are a great solution for ensuring that the correct amount of air is flowing through each branch of the ductwork. Other HVAC optimization techniques that can also play a role in noise reduction include reducing duct rattle, adding sound-absorbing blankets around compressors, improving vibration control of blower motors, and upgrading the HVAC system altogether if it has multiple issues.

Typically fabricated from a sound-insulative frame of mineral wool or fiberglass, they are then wrapped in a decorative fabric to help enhance the interior ambiance of the building. With the ability to approach a noise reduction coefficient (NRC) of 1 with as little as 15-25% wall coverage, they are a low-profile means of sound control in open interiors. Choose Quiet Insulation Generally, all types of insulation will offer some level of sound mitigation over uninsulated areas. However, not all insulation products are created equal in terms of soundproofing. Standard fiberglass batt insulation is less effective as a sound barrier than products such as mineral wool, spray foam, or mass-loaded vinyl.  Additionally, more and more structures are choosing mindfully sourced insulation products. This has made denim batts, fabricated from post-consumer cotton, a trending option in sustainable construction. When comparing denim insulation vs fiberglass , not only will you find that it provides elite R-value for thermal efficiency, but denim is considered a “quiet” insulation product. It achieves an NRC of up to 1.15 with proper application, helping guarantee serene interior spaces. Fortify the Pipes Much like the HVAC system, noisy pipes can become quite the distraction, especially in industrial settings that move a high-quantity of water and steam into and out of the facility. Consider adding mass-loaded vinyl or foam composite around pipes to dampen noise. This will limit the risk of a leak forming during times of extreme temperature and muffle sounds created from pipe vibrations. Create Tranquil Structures with Strategic Noise Control Design Strategies Noise pollution is an increasingly relevant concern in modern buildings. From ICF framing to innovative pipe insulation, consider any of the materials and techniques listed above when designing a building for acoustic performance.

The previous structure, the Union Carbide Building , was deconstructed to make way for the new state-of-the-art facility. The construction phase is expected to generate over 8,000 jobs , involving more than 40 local unions , and contribute approximately $2.6 billion  to New York City's economic activity. Structural Designer:   Severud Associates . Architect: Foster + Partners , a renowned British architectural firm led by Lord Norman Foster Facade Designer:   Foster + Partners . Subcontractors:  Notably, the project includes steelwork supplier Banker Steel , steel subcontractor NYC Constructors , and curtain wall supplier New Hudson Façades . Advisors:   Robert Bird Group  serves as the construction engineering and Virtual Design and Construction (VDC) consultant, provided services such as project modeling and logistics planning. Contractor:   AECOM Tishman  is the main contractor overseeing the construction process. Project Manager: Tishman Construction , serving as the construction manager for the project. Additionally, AECOM/Tishman is listed as the construction manager for the project 270 Park Avenue  front elevation image ( Photo by: Michael Young ) Structural Design The architectural vision for 270 Park Avenue, crafted by Foster + Partners, emphasizes both aesthetic appeal and structural integrity . The building features a steel-framed structure complemented by a robust concre te core, enhancing its lateral stability and resilience against environmental forces   such us high winds, seismic activity, and potential differential settlement due to varying soil conditions. To mitigate wind-induced motion, a 280-ton pendulum-type tuned mass damper is installed on the 54th floor, effectively controlling building accelerations and ensuring occupant comfort. Additionally, the foundation design addresses challenges posed by underlying train tracks, utilizing a 16-inch thick, 10,000 psi post-tensioned concrete slab to distribute lateral forces and accommodate the unique site conditions.

Use of locally sourced GGP in 52,000 cubic yards  of concrete saved about 5,000 tons of embodied carbon and diverted more than 28 million  glass bottles from landfills, as estimated by the GGP producer.  The steel reinforcement in the concrete is made from nearly 100% recycled steel  while the 94,000 tons  of structural steel framing contains over 90% recycled material . Remarkably, 97%  of the demolished Union Carbide building was reused, recycled, or upcycled. Major components of the lateral system are depicted in the below given figures. Exterior macro-braces on the east and west facades are configured in a distinctive diamond shape and augment the lateral system.       East-west braced frames North and south exterior elevations North-south braced frames 270 Park Avenue: Braced frame structure (Illustration by Severud Associates ) One of the standout design elements is the innovative fan-column structure  at the base, which, along with triangular bracing , allows the building to rise approximately 80 feet  (24 meters) above street level.

The interior boasts large, unobstructed floor plates, offering maximum flexibility for various office layouts and fostering a collaborative work environment. The facade incorporates a high-performance glass curtain wall system , utilizing full-height triple-glazed insulating glass units with custom coatings. This approach maximizes natural light penetration while optimizing energy efficiency, contributing to the building's sustainability objectives. 270 Park Avenue. Rendering © DBOX for Foster + Partners Key Challenges in Construction Constructing a supertall skyscraper in the heart of Midtown Manhattan presents unique challenges, particularly concerning foundation design and urban constraints. Site Constraints : The presence of Grand Central Terminal  and Grand Central Madison beneath most of the site left limited space for foundation placement. Narrow Foundation Gaps : Tracks and platforms allowed only narrow gaps—sometim es just 48 inches  (1.22 m)  wide —for new structural support. Utility & Infrastructure Limitations : Existing power, signal, and utility lines could not be relocated due to high costs. Uneven Support Conditions : The western quarter had more direct bedrock support, but symmetry constraints required careful column placement. Complex Load Transfer System : A two-story-high transfer structure (“ Tabletop ”) was needed to distribute loads effectively. Heavy Structural Loads : Super-columns carried nearly 100,000 kips  each, demanding advanced foundation solutions. Construction Constraints : The site was limited by underground railroad tracks and the need to protect the trainshed roof. Fabrication Challenges : Large steel nodes required forged steel fabrication to handle high stresses efficiently. Massive Plate Girders : 25-foot-deep  girders, each weighing ~ 1,800 tons , had to be transported, lifted, and assembled in sections. Limited Site Access : Only Madison Avenue allowed deliveries, requiring precise crane placement and sequencing. A caisson is drilled between train tracks. Access was extremely Limited (Photo by Severud Associates ) Forgings, like this steel node, are weldable and safely transmit high stresses on multiple axes (Photo by Banker Steel ) Conclusion In summary, JP Morgan Chase's new headquarters at 270 Park Avenue exemplifies a harmonious blend of innovative design, structural ingenuity, and sustainable practices. The collaborative efforts of architects, engineers, and construction professionals have culminated in a landmark development that not only enhances New York City's skyline but also sets new standards for future urban skyscrapers. Constructing a high-rise office building in New York City’s dense urban environment is difficult under the best of circumstances. Building one where a high-rise office tower already exists is even more challenging. To attempt to do so above active railroad tracks borders on the impossible. But with thorough study, extensive analysis, and enthusiastic collaboration, JPMorgan Chase and its experienced design and construction team was able to pull it off—without significantly disrupting or altering the trains below. The building is expected to be completed in 2025.  “In 1811, when this site was countryside, the city commissioners created a masterplan for New York. It was bold, innovative, and reflected an optimism for the future . Today, over two hundred years later, the same things are true of 270 Park Avenue. The building is a great investment in the city, the bank, and the wellbeing of the 14,000 people who will occupy it. It does more with less – more public space, fresh air, light and views – and less carbon through electric, green energy.”  –Norman Foster Used Links: https://www.jpmorganchase.com/content/dam/jpmc/jpmorgan-chase-and-co/documents/nyc-270-park-overview.pdf https://www.fosterandpartners.com/projects/270-park-avenue https://architectuul.com/architecture/union-carbide-building https://www.archdaily.com/1010143/foster-plus-partners-tops-out-jp-morgans-skyscraper-hq-in-new-york https://newyorkyimby.com/2024/12/exterior-work-continues-on-jpmorgan-chases-supertall-headquarters-at-270-park-avenue-in-midtown-east-manhattan.html https://www.structuremag.org/article/270-park-avenuemodern-structure-for-a-modern-workplace/ https://www.robertbird.com/rbg-projects/270-park-avenue/ https://www.worldconstructionnetwork.com/projects/270-park-avenue-new-york-usa/ https://buildingelements.com/the-rise-of-270-park-avenue-a-sustainable-building-thats-transforming-the-manhattan-skyline/ https://www.reddit.com/r/StructuralEngineering/comments/15er11e/not_an_engineer_but_i_find_this_foundation_amazing/ https://www.curbed.com/2023/04/270-park-avenue-jpmorgan-chase-headquarters-foster-partners.html https://www.stirworld.com/see-news-foster-partners-unveils-design-for-new-jpmorgan-chase-headquarters-in-new-york

    Water can be chemically combined within soil particles ( chemically or electrically) Water can be easily absorbed in a thin layer of soil. It can freely flow within the pores affecting the overall strength of the soil. 👉 Visit Structures Insider's homepage for more stories. 👈 EFFECTS of water on soil Consolidation Soil changes volume gradually in response to a change in pressure due to pore water pressure.

With the combination of the surface tension caused by cohesion within the liquid and adhesive forces between the liquid and container wall act to propel the liquid. Cohesion: property of like molecules sticking together The surface tension of the liquid: The property of the surface to resist an external force, due to the cohesive nature of its molecules. Pore water pressure (u) = h*γw γw = unit weight of water (10 kN/m3) A History lesson The first recorded observation of capillary action was by Leonardo da Vinci . A former student of Galileo, Niccolò Aggiunti, was said to have investigated capillary action. In 1660, capillary action was still a novelty to the Irish chemist Robert Boyle, when he reported that "some inquisitive French Men" had observed that when a capillary tube was dipped into water, the water would ascend to "some height in the Pipe". Boyle then reported an experiment in which he dipped a capillary tube into red wine and then subjected the tube to a partial vacuum. He found that the vacuum had no observable influence on the height of the liquid in the capillary. Some OTHER effects of water on soil Shrinkage/Swelling: due to loss or gain of water.

  • Pritzker Prize-winning architect Francis Kéré

    Opening the door to a world “unknown” From the Pritzker Prize-winning architect Francis Kéré, we get a glimpse into a world he has known his entire lifetime. In a recent interview with Anne Quito , Kéré and Quito have an exquisite and insightful dialogue about what his experiences living and growing up in Africa are, what the West is missing from the narrative, and how design has allowed him to embody who he is and natures influence on his work. Firstly, lets introduce Diébédo Francis Kéré. Born on April 10, 1965, in the village of Gando, Burkina Faso, Kéré became a Burkinabé architect recognized for creating innovative works that are sustainable and collaborative in nature. He studied architecture at the Technical University of Berlin and graduated in 2004. While studying, he established the Kéré Foundation (formerly Schulbausteine für Gando) and founded Kéré Architecture in 2005. His architectural practice has been recognized internationally with awards including the Aga Khan Award for Architecture (2004) for his first building, the Gando Primary School in Burkina Faso, and the Global Holcim Award for Sustainable Construction 2012 Gold. Kéré has completed many projects in several countries including Burkina Faso, Mali, Kenya, Uganda, Mozambique, Togo, Sudan, Germany, Italy, Switzerland, the USA, and the UK. He was a professor at a multitude of universities including the prestigious Harvard Graduate School of Design, Yale School of Architecture, Swiss Academia di Architettura di Mendrisio, and the Technical University of Munich. His latest achievement is being the first African to win the 2022 Pritzker Architecture Prize. The Triennale Milano’s new exhibition is tackling the Unknown Unknowns. An Introduction to Mysteries: a deep experience, which involves designers, architects, artists, playwrights, and musicians, and gives us the opportunity to overturn our idea of ​​the world. Francis Kéré is tasked with representing the culture of Africa as a curiosity in an international exhibition (which is no easy task). “Kéré described the job of representing Africa at the Triennale as both a privilege and a burden.” —  QUARTZ AFRICA Rather than publishing a long and complicated manifesto, he instead offers examples in the form of installations that show off the originality of Africa while removing any myths and misinformation. Some of his installations include a seating area at the Triennale’s cafe that evokes community gatherings around a big shady tree practiced throughout Africa and a 40-ft immersive tower at the Triennale’s entrance that invites visitors to kneel at one point. The structure is meant to convey the exhibition’s theme of navigating the “Unknown, Unknowns” as well as showcase building techniques and materials remaining in Africa. The sketch of Francis Kéré's 'The Future's Present' tower at the entrance of Triennale | image courtesy of alpha kilo The Kéré and Quito dialogue summarized below is meant to give us more insight into what he wants us to understand about Africa. “Kéré : It’s so immense and culturally diverse; it’s a continent with its own values, history, and expectations on life.” Quito starts the interview by asking Kéré what the world does not know about Africa still. From his perspective, he states that it's clear the West does not understand what matters to young Africans. Rather than seeing it as a young, dynamic continent, Africa is still seen as a place that needs help. print custom invitations If we don't know what matters to our neighbors, then we will never really know them. Additionally, he goes on to say how people in the West consider Africa as only one country. People are not aware of just how large the continent is and how many different countries exist. The next question Quito asks is how he feels about being asked to be a kind of ambassador for the continent. “ Kéré : Being able to talk about Africa is a privilege. I came from a very poor country and suddenly, through design, I have this kind of visibility.” He wants to highlight the idea that even though people are fighting to make a living, they’re generally happy and enjoy life. Having a sense of self-awareness is the key. Just because something makes Western people happy doesn't mean Africans want that. For example, big cars might make an American happy but in Burkina Faso, a good mango tree or a beautifully-designed house out of wood or cement blocks may be more meaningful. Happiness is relative. Installation 'Under a Coffee Tree' by Francis Kéré at the Triennale's café | image courtesy of alpha kilo Quito furthers the interview by asking Kéré if he aspires to link happiness and architecture in his work. Kéré: For me, creating something that helps people lead better, healthier lives is one of the main goals of architecture. I think about this no matter what project I’m working on. He discusses how he approaches his design. He used a chair as an example explaining how he wants people to feel both physically comfortable and also emotionally supported so that they may feel stronger and want to give back to the community. 'Yesterday's Tomorrow' installation is built in the central square of the exhibition hosting the international participations, built as a tribute to the vernacular architecture of Burkina Faso | image © DSL studio Quito continues by asking Kéré what makes African architecture worth knowing. Kéré: Throughout Africa, groups of people have found a way to live in harmony with nature. If you look at the carbon footprint of this huge continent, it’s producing less than 5% of the world’s total emissions. Perhaps we can contribute [ideas] for the rest of the world. Kere talks about his installment at the Triennale called “Yesterday’s Tomorrow.” He says it is about the importance of the past. He speaks about building from knowledge and experience to really serve humanity. It is up to the designers to always consider how it could benefit everyone and thing involved. And if we don’t take this into consideration, we will fail. Quito wraps up the interview by asking Kéré how winning the Pritzker Prize has changed his life. Kéré: This [award] is the best thing that can happen to someone. It will for sure change my life completely and the life of my office. The Pritzker is a big recognition, but I see it more as a push to go forward, you know. I’ve been awarded courage — I feel it, I see it. It’s like saying, “Go, Francis. Do it. Don’t fear.” I feel I have so much energy than ever before. He works and creates from the heart and the mind. He knows he is ready to really keep going. He is hoping that with this new visibility he can use these opportunities to expand his architecture from small to big and really try to care for humanity. “Keep caring — that’s what we’re trying to do.” It is intelligent, compassionate, and creative individuals like Kéré that are what makes being in the AEC industry something to take pride in. He goes above and beyond for the people he cares about and always takes into consideration the community and nature when it comes to design. If more people designed structures with the same kind of intent and love that Kere does, we may just be able to grow in a more sustainable direction for the sake of mankind.
