Types of Welds Used In Construction

A welder at workJoints are an important part of all constructions. Welded joints are the best since they are stronger and have a better fatigue and impact load compared to other joints. They are also smooth in appearance, giving any construction a high aesthetic appeal.

The use of welding is very common in various Edmonton industries such as Advantage Manufacturing Ltd. These include the automotive, aeronautic and construction industries among others. There are multiple types of welds depending on your specific application. Here are some of the common types of welds.

Fillet Welds

Fillet welds are used in joining two surfaces at a right angle to each other. There are several types of fillet welds including staggered intermittent, chain intermittent and full fillet welds. These types of welds are mainly used in biding and bridge constructions typically in a tee, lap or corner configuration. They include plate girders, stiffeners, bracing and bearing connections and end plates.

Butt Welds

These are typically used to accommodate an alteration in thickness or make up the available construction material length in construction. They are usually used in flanges and webs of in-line joints or their rolled sections. Butt welded tee-joints are used in areas where substantial loading and fatigue is a concern in transverse connections.

Groove Welds

Groove welds comprise of beads deposited in grooves between two materials which should be joined. They include single-V, single-J, square groove, single-bevel groove, flare-V and flare bevel welds. Edge-welding joints are a common type of groove welds used to join two adjacent pieces with flanging edges.

A surfacing weld is composed of one or several weaves or string beads laid on a continuous surface to get the desired dimension or property. It is used in building up surfaces or replacing metal on worn out surfaces. At times, a surfacing weld is used in conjunction with a square butt weld.

Design-Build vs Design-Bid-Build: Improving Project Delivery in More Ways than One

Design Bid Build Design-bid-build is one, if not the most common method of project delivery implemented in industries around the world, both public and private. Although new ways of tackling construction projects prove more efficient and more accessible, the popularity of design-bid-build says a lot about the project delivery method’s workability, even if it is not necessarily perfect.

New Methods

One of those efficient, accessible alternatives to design-bid-build aims to simplify the entire process. Through the design-build method, companies can streamline the workflow by hiring a single provider and signing a single contract.

While design-bid-build splits the two components of a project into separate entities, design-build re-integrates both steps and enlists a single contractor to carry them out. By delegating work to a single entity, rather than having to coordinate with two or more, projects are single-mindedly completed. Contractors from hantoclarke.com say that design-build enables a level of focus that two or more contractors cannot achieve at no additional cost.

Across the Board Better

The advantages of design-build extend beyond workflow simplicity. According to a study by the Construction Industry Institute (CII) and Penn State, which studied 351 various project types and sectors ranging from 5,000 to 2.5 million square feet found design-build as the superior project delivery method across several metrics.

Researchers found that in design-build projects, the unit costs are 6.1 percent lower compared to design-bid-build projects. Construction speeds were 12 percent faster, while delivery speeds were 33.5 percent faster. The study also showed that in terms of growth, costs increased 5.2 percent less and schedules extended 11.4 percent less in design-build projects.

More and more industries are discovering the benefits of adopting design-build as their primary project delivery method. While there are certain types of construction projects in certain sectors that will always be better carried out with the help of multiple contractors, the design-build approach proves to be the superior option for most settings and types of projects.

Innovations in Construction: The Rise of Prefabricated Homes

Prefabricated HomesIn February 2015, the first carbon positive home gained the attention of Melbourne homeowners. The prototype was an impressive bioclimatic structure with an 800-square foot floor area. The developers explain this prefabricated home can produce more energy than it consumes.

The innovative use of solar panels makes this prototype the first home of its kind in Australia. The entire house has automatic, smartphone controls.

Whilst 2014 was the year of prefab homes, there is still a lot more room for innovation that we will see in the coming years:

Prefabricated and Green

Carbon-positive homes have yet to become standard choices in the market, but some modular homes for sale come with eco-friendly features. These homes feature sustainable and non-toxic materials. The layout and design maximises natural lighting and ventilation. Some companies have also presented display homes with eight-star energy ratings.

Industry authorities expect the demand for environment-friendly prefabricated houses to increase in the next decade. Their energy saving benefits and simple construction make prefab homes the preferred choice of many people.

The Price of Modular Homes

With the growing popularity of prefab homes, it is not surprising that their prices are on the rise. In the beginning, builders designed modular solutions for low-cost housing and rural or coastal locations. As the choices and demand grow, builders had more opportunities for better housing. Now, it seems that prefabricated residences are no longer limited to rural areas or low-rent neighbourhoods.

Prefab is becoming more popular in Australia, as these are faster to build than traditional home designs. Builders also use quality and eco-friendly materials during construction. Instead of a conventional building, go for prefabricated construction if you are planning to buy a new home or make an extension to your existing property.
