Building greener homes safely

At West Fraser we’re committed to making better products for a sustainable future. Our latest generation of OSB3 is made with a super smooth finish and without adding any formaldehyde, so is safer to work with and builds greener homes. It’s also net carbon negative, like all our products, meaning we lock in more carbon that we emit making it.

There’s zero comparison.

From Photo to 3D Point Cloud The ELCOVISION 10 software creates 3D point clouds from real photos using photgrammetry. The created 3D point cloud can be imported anytime to the SEMA 3D CAD/CAM timber construction software for further planning and construction..

3D point clouds have conquered the digital world in the past two years. There are many ways to create a 3D view of an object. One new and not so expensive way is to generate 3D models and point clouds fully automatically from photos taken by a normal camera or with a drone. The high-precision and high-ly detailed 3D models have an almost laser scan quality.

The development of photogrammetry is advancing.

MiTek 3D Creates New Opportunities

A

n exciting expansion project at a luxury golf course and popular wedding venue in Lincolnshire is coming on apace – thanks in no small part to MiTek and its groundbreaking software.

Trussed rafters provide a structural framework to support the roof fabric, ceilings or floors of buildings in both domestic and commercial structures. The manufacturing process for trussed rafters reduces emissions and pollution and there is minimal environmental impact from installation. It’s a complex project, but with the help of MiTek’s 3D software and products from its Posi-Joist and Posi-Rafter ranges, it’s being turned into reality, and is on schedule for launch to the public in Spring 2022.

As Phil Daniels, MD of component manufacturer DWB Timber Engineering, explained: “Using MiTek and the company’s comprehensive software packages has enabled the team to navigate a complicated steel frame build, deliver savings on materials, and reduce on-site construction time.”

According to MiTek’s Anthony Mitchell, Development Manager, the design was tricky. “Getting all the elements of roof angles, the outside profiles of the steels, ensuring the correct bearings and that the three points of bounds are correct was never going to be easy. On parts of the build there are different steel sizes for the same bearing points. 3D meant the team could prove the concept and pare back the design to make it very buildable.”

MiTek’s 3D software enables designers, architects, and engineers to look at the design in 3D and manipulate it to see how it sits and how it fits. “You can move it around, rotate it, spin it, select an item or area, move it in, move left, move it right, move it up, move it down, make sure it’s in the right place before you go back to the layout and replicate that for everything else that you need,” said Phil.

“Without the 3Ds and the details for the ends, the joiner would have found it pretty difficult because he would have been looking at just section drawings, but you can literally paint a picture in 3D and take screenshots of it, send it to him. He rings me up, asks me a question, and I’ll look at the 3D, take a screehot and send it him back so he can see exactly what’s going on in that point, and then it’s just the discussion of a fixing.”

He added: “The structural engineer had originally specified solid timber joists for the project. But this involves a lot of labour and time, neither of which they had. By using Posi-Joist and Posi-Rafter, we’ve saved weeks on site. We installed both the floor and roof in just a few days, whereas with solid timber you’d have been looking at five weeks, in addition to the added labour costs of four people.”

The project is now a third of the way up and it’s taken the best part of three months, offering unprecedented time savings. Once complete, the new development will provide ancillary facilities to the 55 golfing holiday lodges that have previously been approved at Laceby Manor Golf Course, 22 of which have so far been installed.

Roger Burnett, the owner of Laceby Manor, has made it clear he wants the highest quality building, with the end-result an exceptional experience for his customers. And everyone agrees that it’s going to be a spectacular building when it’s finished.

You can plan and design directly in the point cloud in SEMA. Quasi in ‘virtual reality’. All relevant dimension points are picked up in the point cloud. Whether in plan view, in 3D or arbitrarily set horizontal or vertical sections, the dimensions are quickly and easily determined to be able to plan and design further. This can be for a roof extension, a renovation, extensions or even just an extension such as a dormer or a conservatory.

“The approach is ideal,” adds Roger. “Because I have the dimensions and conditions as they are in reality. A crescent-shaped rafter or a sloping house wall in an old building is common, and I can pick up all this information in the point cloud.

Point Cloud advantages What exactly are the advantages in working with laser measurement and a 3D point cloud? “The inventory is reproduced exactly and to the millimetre, without any deviations,” adds Roger. “With a 3D point cloud, I get reality on the screen. If a wall is crooked, that’s the way it is – and that gives the planner a high degree of planning reliability and helps immensely with the AV. In addition, I can remeasure something in the point cloud at any time without having to drive to the construction site again – that is a considerable time-saver for longer journeys. In addition, the carpenter on the construction site can rely on the fact that everything has been planned exactly and does not have to rework, which in turn leads to higher quality and faster and more accurate work.”

West Fraser’s CaberFloor provides a solution for all applications

When considering flooring products for new-build or refurbishment projects, the housebuilder and specifier can be sure that West Fraser’s CaberFloor range includes the perfect solution. Just as sound foundations are essential for any building, the right flooring system lays a good foundation for a quality flooring finish, saving problems and costs later. The West Fraser website contains a handy flowchart to help builders, specifiers and architects choose the right flooring system for every project, coupled with handy installation guides and videos https://uk.westfraser.com/resources/help-advice/installationinstructions/ for the individual CaberFloor products.

A Proctor Group launches Wraptite® UV airtightness membrane Since its launch, the Wraptite® external airtightness membrane has been an incredible success and has been specified in a wide range of projects and applications. Now, Wraptite is being extended further with the introduction of Wraptite UV.

Leading the field in the popularity stakes, CaberFloor P5 is the UK’s most specified moisture-resistant P5 flooring. The high-strength particleboard is ideal for domestic and most other floors and removes the need for intermediate noggins. The boards are moisture-resistant, stable, durable, easy to lay and, with a tongue and groove or square-edge profile, provide an excellent surface for subsequent floor laying operations. Some floors require more advanced solutions and, no matter the size or shape of the floor being laid, there are key questions to ask. Although not necessarily obvious, the first point to consider is whether the building’s roof will be in place. If the answer is no, the floor will need to withstand the elements. This is where CaberShieldPlus proves its worth as it is designed to allow building work to continue in all weathers.

Wraptite UV is a Class B fire rated membrane that combines the critical properties of vapour permeability and airtightness into one innovative, self-adhering product.

Specifically designed for use behind open jointed cladding, Wraptite UV has exceptional water and UV resistance. In addition, the product provides a shadow gap detail behind open jointed façade systems in offsite construction, rainscreen and timber cladding systems.

The inclusion of Wraptite UV prevents lateral air movement and enhances the building thermal performance. A rating of Sd 0.06m provides a high vapour permeability within a professional quality, selfadhered, airtight breathable membrane.

CaberShieldPlus is an advanced product that has all the inherent benefits of CaberFloor P5. In addition, it offers double-sided protection with a tough, permanent waterproof coating and is BBA approved for 60 days exposure, when laid according to manufacturer’s instructions. It is also a non-slip, safe working platform that withstands high site traffic.

In addition to its use behind open jointed cladding, the membrane is designed for applications that require protection against UV for extended periods. The membrane is ideal for use in the storage and transportation of volumetric modules, offsite panelised systems, and within high rise façade construction.

During its application, the self-adhesive nature of Wraptite UV requires no mechanical attachment and bonds to multiple substrates for airtightness, offering ease of installation, negating the requirement for a primer, sealants, or tapes. Adhesive curing time is approximately 6hrs depending on environmental conditions.

An alternative solution is CaberDek which is BBA approved for 42 days exposure, when installed with CaberFix according to manufacturer’s instructions. The P5 grade flooring has the advantage of a strong, waterproof and slip-resistant peelable film. It provides protection from the elements and construction mess and, when removed, leaves a clean, finished floor. The film is impact, puncture and tear-resistant to withstand high site traffic. CaberDek also provides 44dB sound reduction when used in conjunction with leading I-beam and insulation manufacturers.

Combilift is a clever move for Smartroof

Smartroof is leading the way in developing innovative insulated room in roof panel systems that reduce overall build time, ensure consistent quality as a result of a factory controlled environment, and improve health and safety during the onsite installation process. In line with the company’s drive for sustainability it has switched from diesel to electric power for its fleet of material handling vehicles. These now include four Combilift multidirectional forklifts that have recently been delivered to the manufacturing facility in Swadlincote, Derbyshire.

The company became part of The Keystone Group in 2012 and 2021 was its busiest year to date. As a consequence, there was a marked increase in the volume of materials that need to be handled inside and outside the factory. Due to the extreme size and bulk of the products, which can be up to 12m long and weigh 7t, Combilift was chosen as the preferred supplier.

“We were aware of Combilift’s products, their capabilities and reliability,” said Production Director Lukasz Semen. As we are

extending our production facility and yard, which will triple the size of our current footprint, we need to make sure we can handle our loads with utmost efficiency and safety.”

Together with Glen May from materials handling consultants Forkway, specifications and attachments were drawn up for the two C8000E and the two CBE3000 models, which were supplied in Smartroof’s corporate livery. Although as Glen points out: “Lukasz and his team had really done their homework, and were clear on their requirements. For us at Forkway it was just a matter of firming up the various add-ons and attachments.”

The C8000Es are the largest electric models that Forkway has supplied to date and are used for handling Smartroof’s most challenging loads of 10 to 12m long x 2.7m deep bundles of roof panels. With a 5.5m mast, 6m wide hydraulic spreader beam with 2.5m long forks, they can reach across the truck bed to lift a complete load in one single procedure. With the previous forklifts this necessitated multiple lifts, and what used to take 40 minutes is now complete in 10 minutes.

Spring 2022

The 3t counterbalance design CBEs offload lighter products and components and transport materials to the assembly lines. Thanks to their compact size and manoeuvrability they can move between machinery without hampering production.

There are five cameras on each model, magnetically mounted so that they can easily be repositioned. Blue safety lights for each direction of travel, red zone pedestrian proximity warning lights and work lights for nightshift operation were also installed. A further safety feature is Forkway’s own SpeedZone system which reduces the trucks’ speed from 5km/h down to 3km/h when they transition from outdoor to indoor operation.

“Space utilisation and speed were crucial factors and the Combilifts have been integral to keeping up with fast paced operations and gaining more work space inside,” said Lukasz.

“Without their multidirectional ability we’d have at least 20% less capacity overall. They do exactly what we need and we’re very happy with the outcome.”
