John Canning & Co.’s Post

Projects often require Canning to analyze all types of architectural finishes, including paint, through various processes and techniques. Mechanical and chemical investigations reveal hidden layers, which help define original colors and finishes. Contributing to the overall paint investigation and analysis, historical research of original documents, specifications, and period photographs to help guide the process to where samples should be taken and where paint exposure should be performed.

How do you know if your historic building has a hidden design scheme? A historic paint study will help determine that. In a historic paint study, a number of methods are used to discover a historic building's significant paint and design scheme– mechanical and chemical investigations will reveal hidden layers, scientific analysis will define original colors, and historical research of original documents will help confirm patterns that have been revealed. Once a paint study defines hidden layers, Canning can perform a paint exposure, as seen here. Paint exposures are performed onsite from areas determined by the information retrieved through archival research. #techniquetuesday #paintstudy #paintexposure #historicbuilding #designscheme #historicbuildings #historicpaint #historicpaintanalysis #historicpaints #historicpainter #historicpainters #historicpaintwork #historicpaintstudy #historicpaintinvestigation #paintreveal #paintreveals #decorativepainting #historiccolorpalette #perfectingpreseration #historicrestoration #historicpreservation

The Power of Proactive Surveying: Transforming Designs into Realty: The fine line between expectations and reality As surveyors, we're often tasked with identifying flaws in structural designs. But what sets a good surveyor apart is the ability to revise and improve designs before construction even begins. Unfortunately, many land surveyors fall short in this critical aspect. They fail to dissect the intricacies of design and its real-world applications, despite being the foundation of every design - topography. It's not just about interpreting layout drawings or setting out plans. It's about possessing an aesthetic sense and the ability to envision how a structure will emerge into existence, even before it's built. By proactively addressing design flaws and nuances, surveyors can ensure that structures are built to last, and that the vision of designers becomes a reality. Let's elevate our profession by embracing a more forward-thinking approach to surveying. Share your thoughts on the importance of proactive surveying. #Surveying #Design #Construction #Innovation #ProactiveSurveying

We often get the question why use 3-D concrete printing for our renewable energy structures? There are several reasons to this, including the benefit of being able to print an entire portfolio of products using the same printer materials, equipment what, and workforce in a relatively small footprint. This is possible because we don’t have formwork. Equally important is the potential reduction in mass. The research below indicates 30% reduction in materials compared to conventional concrete construction methods. #concrete #offshoresolar #offshorewind #solarreef

Struggling with Designing Footings? The foundation is one of the most important parts of structural design. It must be strong enough to support the entire weight of the structure, materials, and people. The bottom part of a foundation is called the footing. Footings are critical as they transfer loads from the structure to the earth evenly. They are commonly made of concrete, with reinforcement (rebars) ensuring the effectiveness of the footing. Simplify Footing Design with IDEA StatiCa Detail (3D Beta) Structural engineers often face the complexity of simulating the real behavior of anchoring in footings using traditional methods. IDEA StatiCa Detail (3D Beta) changes that. It enables structural engineers to easily design reinforcement in footings and obtain checks for the Ultimate Limit State (ULS) based on the Compatible Stress Field Method. Comprehensive Footing Design Features: 🔸 Shape of Solid Block: Rectangular or polygon with dimensions and material 🔸 Surface Support: Whole surface or polyline 🔸 Load Transfer Devices: Base plate or single anchor 🔸 Loads 🔸 Reinforcements: Rebar properties and shape definition Detailed Evaluation Report: 🔸 Results of Stresses and Strains: In the concrete and reinforcement 🔸 Bond Stress and Related Values 🔸 Non-linear Deformation Value Try IDEA StatiCa Detail (3D Beta) today or learn more about it here: 🔗 Product Information and Downloads 🔗 Webinars & Theoretical Background #ideastatica #structuralengineering #footingdesign #concretedesign

Creating openings in beams is often necessary for various reasons, such as engineering or architectural requirements and often cannot be avoided. This task, particularly when it involves Glulam beams, presents unique challenges: - Stress Distribution: Introducing openings changes the stress state within the beam, weakening its overall strength. - Sensitivity to Stresses:The beams experience tensile and compressive stresses perpendicular to the fibre direction, which hampers their load-bearing abilities. To ensure the structural integrity of these beams, careful design consideration is essential. While the European timber design code does not currently offer specific guidance for openings in Glulam or LVL (Laminated Veneer Lumber) beams, whether unreinforced or reinforced, the German National Annex to EC 5: Part 1-1 (DIN EN 1995-1-1/NA) provides a comprehensive set of rules for these scenarios. Aiding in the design process, CLT Toolbox has introduced a GLT Beam Penetration Calculator. This tool is crafted to facilitate the assessment of openings in GL beams, in line with the draft prEN 1995-1-1 and the NZ Wood Design Guide. It caters to: - Both rectangular and circular openings. - Considerations for reinforcement. The calculator is grounded in a key principle: the area around an opening can't transfer shear and bending stresses as usual. These stresses are rerouted by a tension force, perpendicular to the beam axis. This force becomes the foundation for designing beams with openings, guiding decisions on whether and how to reinforce them. In the case of unreinforced openings, the focus is on leveraging the beam's existing capacity at the opening. When this capacity proves insufficient, reinforcements, like fully threaded screws, provide the necessary support to uphold the beam's structural safety and functionality. #clttoolbox #gltpenetration #glt #structuralengineering

Horizontal Alignment of a road lies at the backbone if Highway design. It is the layout of the road center line in a horizontal plan It is mainly composed of °straight section °curved section (circular, spiral, compound curves etc) °Super Elevation Some of the factors that may be considered during horizontal alignment are -Topography -Safety -Esthetics -Environment -Design speed I have also noted that it is important that one should pay attention to the following parameter when designing a horizontal *The Minimum Radius* Values for minimum radius may vary from country to country but it is mainly affected by the design speed and the super elevation *Length of a straight section* This is also controlled by the design speed and also vary with country road design manuals Long straight sections should be avoid to reduce glare *Clothoidal parameter (A value)* This is the rate of change of curvature and it allow for a gentle change in super elevation from a curve to a straight section (super elevation runoff) *Design speed* This is affected by the parameters listed above, sight distance, gradient and other factors
