DMD slab edge moulds Expressed slab edges are a new trend in multi level concrete building design. This feature is a simple way to add interest to a multi-storey building — curves and profiles on a slab edge that extends beyond the building envelope can create interesting forms and flows to the surface of a building when seen from the ground. DMD moulding systems to achieve this are primarily: single use EPS (polystyrene), fibreglass, formed steel, and cast steel — sometimes combinations of the above. We choose the method most suitable for the profile, surface finish, the number of repeat uses, the scale of the project and the budget. An important part of our work, is to analyse a project, dissect the design into workable sections, model all the individual parts, fabricate and supply them with labelled installation charts. Our aim is to make the (often) most complex looking part of a build the easiest. When there is twenty-five floors of slab edge with lots of variation it can seem overwhelming but we can solve it all and deliver accurate moulds to make this important feature of your building really work.

A prefabricated construction used to establish and secure property boundaries is called a prepared compound wall, often referred to as a precast boundary wall. To ensure consistency and durability, these walls are made off-site in a controlled environment with premium concrete and other components. https://lnkd.in/gjCx8Uvc #ReadyMadeCompoundWall #CompoundWall #HomeSecurity #WallDesign #PrefabWall #WallInstallation #ExteriorDesign #GardenWall #BoundaryWall #ConcreteWall #WallFence #ModularWall #WallConstruction #WallPanels #SecurityFence #OutdoorWall #PerimeterWall #WallSolutions #LandscapeDesign #PropertyBoundary

How much timber, really? Well, that was an interesting exercise. In an attempt to get another designer’s project currently under construction over the line for a 6 star Homestar rating, I calculated the ratio of timber framing in one elevation. This is a fairly typical, simple two storey / two bedroom terraced housing project. The elevation in question is a featureless flat façade with minimal window openings (it’s the east-facing rear wall). NZS4214, the standard regularly used to determine the thermal resistance of building elements, allows us to assume that a wall is made up of studs and dwangs evenly spaced at the maximum permissible distance. For a 2.4m high wall with studs at 600mm centres and dwangs (or nogs for my North Island friends) at 800mm centres, that’s around 15% of timber. The rest can be filled with insulation. After a BRANZ / Beacon Pathways report found average as-built framing ratios were actually more like 34%, Homestar requires us to assume 30% framing unless proven otherwise. This is because all the extras like lintels, double & trimming studs, internal wall connections etc. etc. add more thermal bridges than you would realise. Alright, I thought – here’s a good chance to use this. And at first glance, the panel elevations looked relatively efficient. I’ve seen a lot worse, that’s for sure. So take a guess at the actual result… . . . . . . . . . . . . The lower level is 27.8% timber, and the upper is 34.5%. That’s 31.15% for the elevation. That means the wall’s constructed thermal resistance (with R2.8 batts) is really R1.91, not the R2.42 the designer could use for their building code compliance calculations. There are lots of ways to address this, but if your designer is targeting code compliance as a benchmark it will most likely be ignored and your project will be performing a lot worse than you think!

Homestar covers a lot of areas of sustainable design, but it’s interesting to see where it directly impacts designers and encourages them to do better. - Framing percentage/fraction is one area I see that comes up quite often. - Another is accounting for and addressing critical thermal bridging for both heat loss and mould avoidance - And, another is effective ventilation. Hard to know how well these follow through to construction quality on site, but still good steps forward for the industry.

Brick is one of the oldest construction materials used in construction. It is known as a cheap, and durable material. Bricks are used for the installation of exterior and interior walls, partitions, piers, footings, and other load-bearing structures. The bricks are made in a rectangular shape and size that can be easily laid with one hand. It can be made of burnt clay, a mixture of sand and lime, or Portland cement concrete. Clay bricks are commonly used because they are economical and available. Bricks can be defined as a structure made of solid and solid inorganic metal in a simple geometric shape. They have been the basic construction materials for centuries, contributing significantly to architectural and engineering design. -------- Read more: https://lnkd.in/gUMnBPWz

Basics Of Spiral Staircase Design

The history of SIPs (Structural Insulated Panels) construction dates back to the early 20th century. The concept originated from the Forest Products Laboratory in Madison, Wisconsin, in the 1930s, where researchers were exploring ways to use wood products more efficiently. They developed a panelized wall system where the plywood sheathing carried a portion of the axial load. In the 1930s and 1940s, renowned architect Frank Lloyd Wright popularized SIPs with his Usonian houses, many of which still stand today. The modern SIP was further developed by Alden B. Dow, one of Wright's students, who created the first laminated SIP with a core of insulating foam. The oil crisis of 1973 led to a surge in interest in energy-efficient building methods, and SIPs gained popularity in the US and Canada. The development of Oriented Strand Board (OSB) in the 1980s further advanced SIP technology, making it more widely used in construction. Today, SIPs are recognized for their energy efficiency, strength, and ease of installation, making them a popular choice for residential and light commercial construction.

Structural characteristics of container houses Modular design: Container house adopts modular design, each box is generally an independent module at the factory, similar to building blocks, very flexible and efficient. Steel structure: The main structure of the container house consists of a steel frame, corrugated side wall panels, floors and their additional beams, which are welded to each other to form a complete and independent box structure. Rugged: Steel construction makes container houses with extremely high load carrying capacity and seismic performance, suitable for use in harsh environments.
