Graphene

Posted by Steadfast Entities on

If you follow our blog, you know we love green materials that make construction more sustainable. That’s why we’re excited to see graphene now entering foreign markets. We can’t wait to see how this incredible component will be used to make our buildings more sustainable, in 2023 and beyond.

What is it?

Graphene is a “one-atom-thick layer of carbon atoms arranged in a hexagonal lattice.” Andréy Gueim and Konstantín Novosiólov won the Nobel Prize in Physics for its creation in 2010. It might sound familiar because it is the base of graphite (used in pencil lead), but its many properties are being explored as a new wonder material across a wide variety of industries. Possible applications include computer chips, batteries, transistors, water filters, touch screens, and even DNA sequencing. 

How is it being used in construction?

Although graphene is still in the research stage in the US, the results have been promising for its many uses throughout the construction industry. It’s the world’s thinnest material, yet it’s incredibly durable. It has antibacterial properties, a low freezing point, is twice as strong as steel, has light absorbing qualities, and is highly conductive. 

These features make it perfect for creating graphene-infused composites, which would be a green alternative for concrete, one of the least sustainable yet most commonly used building materials.

Some of these specific properties would make graphene an excellent choice for specific types of buildings. Its antibacterial qualities are making waves in the hospital industry, its conductive qualities are sparking the interest of smart city engineers, and its unique mix of flexibility and durability makes it well-suited for buildings that experience extreme winds and temperatures. 

Graphene also has potential applications in tunnel construction, dykes, bridges, harbors, industrial plants, and sea construction, where exposure to the elements and/or chemicals regularly breaks down concrete. 

How will it be used?

Instead of sheets or blocks, the easiest and most effective way to use graphene currently is as a liquid-based additive. This additive is combined with current cement or concrete mixtures, acting as a filter that absorbs chemicals, refines the pore structure of the concrete, and makes it more durable. 

When will we see it on the market? 

While additives are available in some countries, researchers are still testing and developing it for the U.S. While we may have to wait a little longer, current research is very promising and exciting. Soon graphene may be used in self-healing, self-cleaning, self-adjusting, self-shaping, self-curing, and self-sensing building materials. We are looking forward to its arrival, and the many ways it will make the industry more sustainable!

Data Collection Apps

Posted by Steadfast Entities on

At Steadfast, LLC, we love new construction technology. We can’t wait to share information about the newest materials and gadgets that will keep your staff safer, make your projects go faster, help the environment, and make you money. And while they might not be as much fun as drones or concrete made from lunar dust, data collection apps can do all those things and more. 

What are Data Collection Applications?

Put in the simplest terms, data collection apps are mobile programs that collect and store information about your project before, during, and after the job. 

Construction teams have been collecting data for years (think blueprints, the types and amounts of materials they would need, incident reports, etc.), but up until recently that data was kept on paper. While paper has served us well, it did come with some problems, like being easily damaged (hello, coffee stains), bulky, time consuming, and prone to error. 

It’s no surprise, then, that computer engineers started working on data collection software as early as the 1980s. Thanks to the cloud, this software has become one of the most widely-used technologies on construction sites today.

All kinds of useful data can be collected via these applications: they take and share pictures, GPS locations, signatures, and more. You can pull up plans, forms, schedules, and other documents without having to carry around bulky paperwork. And most allow you to store data offline, so they can still be used in areas without reliable internet. 

How can they help you?

If you already have a paper system, it might be tempting to not change something that’s not broken. Just because something is functional, however, doesn’t mean there isn’t a much, much better way. These data collection apps are so effective, even the most traditional site managers are making the switch. You can’t argue with the many financial and safety benefits!

1. Saving Time

How would you feel about having 20 hours back in your week? 

That’s how many administrative and field hours that app users report saving, thanks to increased efficiency. Since the software reduces data entry errors, you aren’t spending time correcting mistakes or hunting down missing signatures. 

GPS allows staff to easily find the exact site where a fix is needed, and you can easily send pictures and videos so everyone doesn’t have to drive to the site. And this improved workflow has one bottom line: jobs are finished in record time, meaning you’re making money faster.

2. Keeping Workers Safe

You want to keep your workers safe. Yet most workers avoid completing lengthy or complicated forms when they can, so many near-miss accidents or inspections get skipped. By making them accessible digitally, your team can quickly get through daily equipment inspections, easily complete near-miss reporting, and immediately access job safety analysis.

3. Reporting Instantly

The improved workflows brought to your team through data collection apps mean you can do your daily job reports, send client deliverables, and access legal documents right from your phone or tablet at your jobsite. Clear results and the ability to make instant decisions will help you have more accurate and dynamic control of every project. 

Which one should we use?

As data collection continues to improve, more apps are becoming available every day with a wide variety of user friendliness and prices. When considering which one to use, there are some important factors to consider. 

First, what devices will you be using? Many apps are specific to iOS (iPhones), android, or web technology. Next, what type of internet access do you have? If you are regularly working on jobs in areas with little to no internet access, you’ll want to make sure the app you choose has several offline options. Finally, will you be taking measurements one time or repeatedly? All of these factors, along with price point, will go into figuring out which app will work best for you. 

Explore a list of some of the most popular apps here. 

At Steadfast, LLC, we’re committed to helping you find the best staff, equipment, and technology to help you complete your jobs safely and efficiently. Contact us today to find out how we can help you get the job done right: jhworthy@steadfastentities.com.

More About Mass Timber

Posted by Steadfast Entities on

If you go back through Steadfast’s blogs, you’ll find a lot of information about new, sustainable building materials. Whether it’s concrete strengthened with algae, buildings built with recycled steel, or solar roof shingles, we’re thrilled to see the construction industry moving towards a more sustainable future. That’s why we’re excited to see the Mass Timber industry booming in the U.S., Canada, Europe, and beyond.

What is Mass Timber?

Put simply, mass timber is made up of several solid wood panels held together by nails, glue or dowels. The compressed wooden layers are stacked either at 90 degrees or parallel, making these panels incredibly strong and a comparable alternative to steel and concrete. They are strong enough to withstand earthquakes, high winds, and other forces that previously prevented wood from being used as the main building component in large, multistory buildings.

Is it Sustainable?

Mass Timber is more sustainable with fewer embodied carbons, and requires less water and energy to produce than concrete or steel. Wood also stores carbon in its structure, meaning that Mass Timber buildings actually remove excess carbon from their environment. For example, an 18 story Mass Timber building has an annual negative carbon imprint the same as taking 2,350 cars off the road. 

Forestry has also become more sustainable as the need for lumber has grown. Current practices mean alternating trees are cut down during harvest, allowing the remaining trees to grow taller without competing for sunlight, water, and other resources. Forest growth is also maintained by planting two saplings for every tree harvested, making sure that there will be plenty of timber available in the future. 

Is it Fire Safe?

When most people think of wood buildings, their first concern is fire safety. Fortunately, Mass Timber generally exceeds current fire codes. In one study, a panel was exposed to 1,800+ degrees Fahrenheit for two hours and six minutes, longer than current code requires. The panels don’t only sustain the heat without a problem, but the outside layer of Mass Timber will char, insulating and protecting the inner layer. This means cleanup and building rehabilitation is often easier and faster.

Is it Cost Effective? 

Yes, especially in comparison to concrete. Because Mast Timber panels come preassembled, they can cut down on construction traffic by 90%. Buildings are also constructed about 25% faster than those made predominantly from concrete. Because of this, projects can cost less with fewer safety risks to workers. While the panels themselves are usually more expensive than concrete, the overall cost to both the crew and the buyer is much less.

With all these benefits, we expect to see continued increases in Mass Timber construction. Steadfast, LLC has the modern tools and skilled staff you’re looking for to get your next Mass Timber (or any other type) project off the ground. Contact us today to see how we can help! 

What is As-Built Capture Technology?

Posted by Steadfast Entities on

Imagine being able to upload all of the information about a jobsite to an app in 15 minutes or less. You’d have everything you need right at your fingertips: the building plans, the layout, the stage of construction, and even photos of where things were. Thanks to as-built capture technology and drawing apps like Novade, this is no longer a work of imagination. Construction companies around the world are using it daily to improve safety, efficiency, and communication.

No More Jobsite Walk

We all know time is money, and jobsite walks are extremely time consuming. First you have to get to the jobsite, and then once you’re there it’s an exhausting list of inspecting individual elements, taking hundreds of photos, uploading them (which can take hours), and then comparing them with the original blueprints. Then, of course, you have to repeat these steps with each new phase of development.

As-built capture technology is getting rid of this chore. Using laser scanners, 3D reality capture cameras, and coordinated measuring machines, contractors now have a wide variety of tools readily available to quickly and efficiently gather information from their sites.

Simple Tech

The best part of as-built capture technology is that it’s incredibly simple to use for the less-than-tech-savvy among us. For instance, OpenSpace is a reality capture software system that automatically maps jobsite photos to building plans. A contractor simply has to strap their 360 degree camera to their hardhat, turn it on, and do a simple walk through the jobsite – no photos, notes, or additional walkthroughs required. 

In under 15 minutes, the imagery is uploaded to the app and connected to the plans. This is great for companies that regularly upgrade or remodel the same buildings every few years, because the building layouts and plans can be reused for decades.

Laser Scanners

Lasers are no longer the thing of sci-fi thrillers; they’re regularly being used in construction and other industries to capture precise measurements. Companies like FARO have developed laser scanners that allow users to create 3D maps of the building or jobsite in real time. They’ve also used this technology to create a laser projector, which can accurately project a laser outline onto a 3D surface, which is then used for prefabrication applications. One of their newest products is the Boston Dynamics Spot Mobile Robot, which allows for autonomous scanning by a robot and is perfect for unknown or dangerous worksites. 

Safety & Efficiency

As-built technology does more than just save time by eliminating jobsite walkthroughs. A picture is worth 1,000 words, and having real time 3D images readily available for review allows for increased accountability. It also improves conflict resolution and communication for your entire crew. With decreased travel costs and the reduced risk for workers due to fewer unknown or dangerous situations, we expect as-built technology to continue to rise in popularity at job sites across the country.

At Steadfast, LLC, we are always looking for the best people, technology, and equipment to make your job run as safely and smoothly as possible. If you’re in need of quality staffing or equipment rentals, contact us today! With our decades of experience and vast network of brands, we have the modern solution to any of your smart construction needs.

New Tech Inventions for 2023

Posted by Steadfast Entities on

We love new technology here at Steadfast, LLC, so it’s no surprise that we couldn’t wait to check out Time Magazine’s list of the 200 Best Inventions of 2022. We were especially interested in those with exciting applications in construction in 2023 and beyond! Check out these construction innovations:

Holograms No Longer Just for Star Trek

The Magic Leap 2 is an augmented reality headset that provides interactive holograms used across various industries, including medicine, retail, and manufacturing. In the construction world, Magic Leap 2 can be used to view large buildings and other worksites at scale. This allows teams across the globe to work together despite distances. With just one click, they can provide BIM updates to allow teams to make real time changes, quality assurance, and more.

Tape Measures That Really Measure Up

The world’s first industrial grade digital tape measure, the TI Tomahawk by Reckon Tools is a game changer. With just the click of a button it can take precise incremental, center, and internal measurements. Reckon Tools also created the Reckon Rock App, where users can upload and share their measurements from the TI Tomahawk using Bluetooth technology.

Autonomous Drone

Drones are becoming a staple in the construction industry, but a shortage of qualified, licenced pilots is making their application difficult and expensive. Fortunately, Leica Geosystem’s BLK2FLY flying laser scanner is coming just in the nick of time. Operators use virtual joysticks within an app to fly the machines, so a drone license isn’t required. The system uses GPS, radar sensors, and cameras to navigate obstacles and create digital twins of worksites, building structures, and more. 

Solar, Simplified

While solar rooftop arrays are known for saving energy and cutting down your electric bill, setup is expensive and can cost thousands of dollars more than a traditional roof. That’s where the GAF Energy Timberline Solar Roof System comes in. The system includes solar ‘shingles’ that can be installed by a traditional roofing company with a nail gun. It’s also a certified solar and roofing product with a 25 year warranty, making solar more accessible for businesses and families everywhere. 

Wind Power at Home

Keeping in the theme of renewable energy on the roof, Aeromine Rooftop Wind Technology has patented new technology to capture wind energy. Generating 50% more energy than most solar arrays and having fewer parts to break than traditional small wind turbines, these units perform under even the most extreme weather conditions and are perfect for buildings with large, flat roofs, like big box retail stores, warehouses, and multi-family developments. 

Remote Operating Remotes

To help combat the labor shortage, Phantom Auto has created a remote operation program for forklifts that allows operators to login from anywhere in the world. With LIDAR sensors, high resolution cameras, and real-time video, this technology increases operator productivity and available labor pools while decreasing operator injuries.

Technology is always changing in the construction industry and at Steadfast Entities, LLC, we pride ourselves on maintaining up-to-date, industry-proven tools, equipment, and technology giving you modern solutions for all construction needs. Contact us today to see how we can help!

Fun Times and Fungi in Construction

Posted by Steadfast Entities on

Mycoremediation (my-co-re-media-tion) may sound like something out of a sci-fi novel, but it’s actually just the name of a process that nature has been doing since the beginning of time: using mushrooms to break down natural materials. 

Nature’s Garbage Disposal

Mycoremediation is a fairly straightforward process. Fungi release enzymes that break down organic matter into simple sugars, and then use those sugars as fuel. So the scientists working with Australian-based contractor Lendlease had a great idea: why not use this process to help reduce construction waste? 

From Construction to Compost

According to the EPA, the building industry in the US alone generates more than 600 million tons of construction debris every year, including 11 to 13 million tons of asphalt shingles. Most of those shingles end up in landfills, with only 5-10% being recycled or reused. 

With this in mind, Lendlease created their first mycoremediation pilot program. They used three different types of fungi to break down the roof shingles from 214 houses in Fort Campbell, Kentucky. While they did not state the exact amount of time they expect before the shingles have completely decomposed, it is expected to be substantially faster than the 300 years it would normally take for asphalt shingles to break down on their own. Once decomposed, the shingles can be reused as compost for growing food.

Great for the Planet and Your Wallet

Mycoremediation is proving to not only benefit the environment but also the economy. Lendlease believes their building-debris-to-compost plan could be a profitable income stream, and plans to expand their mycoremediation to include other building materials like drywall. 

Eventually, they hope to sell the compost and make more money than would be spent to get rid of the waste at a landfill. In the words of Sarah Neff, the head of sustainability at Lendlease: 

“Taking a product that is no longer viable and combining it with a natural renewable source that results in a new product, is a phenomenal outcome that is both beneficial to the environment and bolsters the economy.”

As more and more companies consider their environmental impact, we expect to see mycoremediation and other sustainable practices being used more and more throughout construction.

3D Printing in Construction: Pros & Cons

Posted by Steadfast Entities on

3D printing has been around since the early 1980s, but over the last few years it has ballooned into one of the fastest growing construction technologies on the market. Its versatility, efficiency, and economy make it a useful tool in every step of the construction process.

How Does It Work?

To create a 3D print, a CAD or BIM program sends the required information to the printer, which then prints the object in layers. While these layers can be many different types of materials, the most common used in construction is a mixture of concrete, sand, fiber, and geo polymers. 

SQ4D, an Australian construction company, has built an industrial sized 3D printer that they can use to build housing on any lot. You can watch a video of the building and see the finished home here. 

Why 3D Printing?

Thanks to the CAD or BIM programming we mentioned before, builders using 3D printers know the exact amount of material they need for the project. This cuts down on waste at the jobsite, as well as the cost of surplus materials and their storage, making 3D printing more sustainable and cost effective. On average, 3D printed projects generate 60% less waste. 

3D printing also saves time, with 3D printing going approximately 70% faster than traditional builds. This time saving allows companies to start and complete more projects, which increases both profits and, if building housing, the number of living spaces readily available on the market. 

Finally, since 3D printing works autonomously, it requires fewer laborers on the jobsite (most companies that switched to 3D printing saw an 80% decrease in labor costs). Since the construction industry has been hard hit by labor shortages across the country, this both saves companies recruiting money and allows them to complete projects on time with far fewer staff. The projects are also much safer for workers, with a substantial reduction in construction injuries when workers have been trained to use 3D printers.

Ongoing Challenges

While 3D printing has a wide range of benefits, there are still some disadvantages. The printers, especially those large enough to be used on construction projects, are incredibly expensive, and can be a challenging upfront cost for new companies. With so few printers being used in the industry, there’s a high need for fully-trained operators who can design the computer models, operate the printers, and provide the required maintenance. 

3D printed projects are also limited by the formula of the mixture they print. The mixture has to exit a nozzle, retain its shape, and have a ‘goldilocks’ dry time: too slow and it can’t be layered, too fast and it will hinder the building process. 

Despite the constraints, the increased flexibility, efficiency, and safety of 3D printing means it is a growing tool in the construction world and expected to be a $680 million industry by 2030. As construction professionals dedicated to both sustainability and using the most cutting-edge technology, you can count on Steadfast, LLC to keep a close eye on the evolution of this technology! 

Positively Electrifying: Equipment of the Future

Posted by Steadfast Entities on

Electric Vehicles

While electric cars have been readily available in the US for the last decade, sales had remained fairly low until the first three months of 2022 when they shot up 60% (despite the vehicle market being down 18%). Skyrocketing gas prices, concern surrounding the environmental impact of carbon emissions, and the improved design of new models have the American public turning to electric cars, trucks, and even semi-trailer trucks. 

The Electric Bobcat

What about heavy equipment? Although some all-electric machines have been on the commercial market for the last few years, companies have shied away from integrating EV technologies into heavy equipment for fear they didn’t have enough power or wouldn’t hold a charge long enough to do the necessary work. 

However, many in the construction world are pushing for cleaner machinery to lessen their carbon footprint. Equipment giant Bobcat just announced the release of the first all electric compact truck loader and an electric compact excavator.

Their unique compact truck loader, the Bobcat T7X, will start shipping in 2023. The T7X has completely eliminated all hydraulic components. Instead, it relies on an electric drive system with electric cylinders and drive motors. The first of Bobcat’s electric excavators, the Bobcat E32e, began shipping in August and is already receiving rave reviews. 

Market Forecast

While electric equipment still has higher up front costs, the rising costs of diesel is making the cost of smaller EV equipment, like mini excavators, more favorable. In fact, a recent report from IDTechEX has forecasted the global market for electric construction equipment to grow to $105 billion in the next 20 years, a steep rise from the current market, where there are only about 2,000 all electric machines being sold annually. 

Battery Life & Pricing 

We are still several years away from larger EV equipment being easily accessible for companies without substantial financial backing. This is mostly due to concerns surrounding battery life. 

Just like when your cell phone loses battery life after too many charging cycles, many are questioning how long the charging capacity will last for current EV batteries for larger machines. If a battery needs to charge on the jobsite, that’s lost time, productivity, and revenue. Buying a second battery to swap out requires more funding upfront for these expensive units. 

However, the high upfront costs are partially balanced by the fact that electric vehicles require far fewer parts and less maintenance than their diesel powered counterparts. That means there are fewer components that could break (ex: no fuel injectors or hoses to burst) and fewer parts that require regular maintenance (ex: filters, fluid levels), which will save companies money over time.

While the technology is exciting, only time will tell when the US will move towards all electric machinery on jobsites. However, one thing is for certain: you can always count on Steadfast Entities, LLC to have the quality equipment you need to get the job done. Contact us today!

Construction Drones

Posted by Steadfast Entities on

Flying Across Industries

Over the last fews years, drones have become a common tool throughout many industries. 

Real estate and vacation agencies regularly use them to take photos and videos of their available properties. They’re making a splash in the entertainment industry by capturing footage for documentaries, sporting events, and high-action scenes. 

Just this year, Amazon started using drones to deliver packages lighter than 5lbs as part of their Prime Air service. With the increased commercial use of drones, it’s no surprise that they are becoming more prevalent in the construction industry as well.

Construction Drones

The construction industry as a whole has experienced a 239% growth in drone use since 2018. Their ability to easily and safely collect large quantities of data quickly has made them an integral part of many projects, from the initial planning stages all the way to completion. With their speed and efficiency, they save contractors both time and money.

Fixed Wing vs. Rotary Drones

There are two different types of drones commonly used in construction. 

Fixed wing drones are modeled after airplanes and built for distance. They are typically used for mapping and scanning larger areas. However, due to the fixed status of their wings they can only go forward, so tight areas with obstacles are not a good fit. 

For those tighter areas, most companies use rotary drones. These typically have a dual rotor design that allows these machines to hover up, down, and in place. They are used for photography, surveillance, aerial inspections, and structural scans. 

High Level View

For large-scale construction projects, drones are also commonly used for land surveys and topographical mapping. They can typically survey vast swaths of land in 15-20 minutes to create highly accurate topographical maps. Teams can then combine these maps together to form 3D models, which are used for analysis and project planning. 

The best part? By easily spotting terrain challenges and design flaws early in the planning process, crews can change design plans ahead of time instead of trying to fix them in the moment. This saves both time and money and ends up being 20 times less expensive than traditional surveillance and mapping processes.

Security from the Sky

Similarly, drones can be used to quickly and easily monitor equipment on a large job site, making sure it is where it needs to be, when it needs to be there. If it’s a rented piece of equipment that should no longer be on site, you’ll be able to identify and return it quickly, avoiding additional charges. They can also be used for safety, ensuring secure equipment, and preventing unauthorized access on the jobsite. 

Improved Communications

Drones are also being used to help improve communications, both with clients and other members of the construction team. By providing aerial views of projects, clients get a real-time view of what you are doing and how far along you are on the project. And by sending collected data to connected software, owners, engineers, design teams and workers are updated in real time. This provides a paper trail for future use, allowing the whole team to work together to catch any potential mistakes or design flaws quickly. 

Safety Watch

Drones are also contributing to increased safety on job sites. They can be used to make hard-to-reach measurements without the need for unsteady platforms. This reduces the fall risk for workers, who can operate drones from the safety of the ground. 

Similarly, many companies have started using them for building and property inspection. Instead of using a team of surveyors, heavy machinery and scaffolding, drones are flown around the building or job site to take high resolution images that are later analyzed. They also have thermal sensors that can detect electrical issues, cold spots and heat leaks before they become a problem.

While drone technology is still developing, the increased safety, efficiency, and monetary benefits for workers, project managers and clients are very compelling. We can’t wait to see how this technology will continue to revolutionize the construction industry!

Smart Roads

Posted by Steadfast Entities on

With rising gas prices and increased concerns about climate change, many are turning to electric vehicles to protect their wallets and the planet. However, scientists and construction engineers have been working hard on another part of the transportation equation: smart roads. 

While the technology is still being refined by scientists and construction engineers around the world, the smart road concept uses digital technology, IoT, and fiber optic connectivity within their foundation. Using wifi, 5G, the cloud, and in-road sensors, smart roads will allow for a multitude of improvements for all drivers, whether their cars use electricity or gas. Benefits include:

1. Less Traffic and Congestion 

smart roads will be able to collect and analyze data in almost real time. When used in conjunction with smart stop lights, they could adjust lights based on current traffic conditions, decreasing slow downs and bumper-to-bumper traffic.

2. Increased Safety 

Pedestrian deaths have increased by 46% over the last ten years. Using image processing, AI, and object recognition software, smart roads can broadcast information to vehicles on both roads that make up an intersection, allowing drivers increased awareness of pedestrians, bicyclists, and others who may be in danger of being in a turning driver’s blind spot. 

3. Increased Connectivity 

With smart roads constantly connecting data, drivers will be able to get updated information on the best routes to avoid traffic and slowdowns. Smart parking apps could also show drivers where spaces are available, ending the time spent fruitlessly circling city blocks looking for a spot.

4. Decreased Emergency Response Times 

By monitoring traffic and slow downs, emergency responders could know when and where an accident occured, and synchronized traffic lights with emergency vehicles would decrease response times by 20-35%. 

5. Energy Harvesting 

Developing smart road technology would allow energy to be harnessed from the vibrations of passing cars or sunlight. This energy would then be returned to the electric power grid and used to power traffic lights, signs, and street lights.

6. No Weigh Stations 

The development of high speed, weigh-in motion technology would allow for trucks and other large vehicles to be weighed while they are on the move. They would also provide weight enforcement screenings for toll roads, bridge loads, and traffic control data. 

7. EV Charging 

For drivers of electric and hybrid cars, smart roads could also allow charging while driving. This would also increase the availability of public transportation, as electric buses could run all the time without having to stop. Smart pavement, created by incorporating metal coils in pads of concrete, could charge EVs wirelessly as drivers go about their day. 

One of the biggest challenges to the creation of smart roads is the ability to process large amounts of data from multiple sources in real time, but many of these technologies are already in testing and are expected to be released to cities worldwide in the next few coming years. 

As more cities convert to this exciting technology, more workers will be needed to build the roads and other elements of smart cities. When that time comes, Steadfast Entities, LLC will be ready with the latest products, trained staff, and equipment rentals to meet all of your construction needs.
