Cutting edge technology becomes best practice on construction projects

3D laser scanning is back in the headlines – this time in Louisville, Kentucky – showing further proof that this innovative technology is quickly becoming the new industry standard for construction projects across the country.

Just last week, work on the $2.6 billion Ohio River Bridges project in Louisville began and 3D laser scanning technology is playing a key role in the progress.

The project includes reconstruction of ramps for the John F. Kennedy Memorial Bridge and interchanges at the intersection of three major interstates, a second bridge to carry northbound traffic on I-65, and a new East End Bridge to connect two major highways located 10 miles from downtown Louisville.

Kentucky is excited about the project and the clock is ticking! There is reportedly $12 million in bonus awards ($40,000 per day) available to the contractors if construction is completed early and an $80,000 per day penalty if the project is late.

So, when the contracts were awarded late last year, site crews mobilized fast.

The subcontractor providing surveys for the massive transportation project is using 3D laser scanning to plot the entire landscape of construction. This technology enables sketches and plans to be  immediately uploaded to the cloud as they are completed so that crews can access the most recent data in real-time.

As a result, crews can conduct clash detection of existing and proposed construction to show if there are interferences that could potentially slow construction and can make modifications before they cause major construction problems.

As the many benefits of 3D laser scanning become more known, this technology has become a best practice for critical projects.

Many construction companies have even been rolling out flat screen computers onsite to show superintendents actual BIM models by sequence. These models are used throughout the day by workers building bridges, roads and infrastructures around the world.

Construction companies use these high definition laser scans to gather precise data on site terrain, renovations and additions. Architects use them to check proposed design models against existing conditions to fine-tune their designs, and engineers use 3D scans to work with real-world conditions in complex industrial as-built and plant environments.

The scans are quick, accurate and highly detailed and the result is big savings of both time and money. Not only can you revisit the original scan multiple times from a computer desktop, which eliminates costly return visits to the project site, but scans also prevent construction reworks and retrofitting and keep projects on time because they are completed right the first time.

At $80,000 per day, I’d say that’s worth it!

Surviving 2012: Six things every business can learn from the surveying industry

As a professional land surveyor for 40 years, I have a first-hand understanding of the housing downturn and subsequent economic recession we have been experiencing for the past six years.

At our firm, we began seeing the impact in early 2008, just one year after the peak in our business in 2007. Surveying is often viewed (at least by banks) as part of the construction industry and when construction loans dried-up, so did our business.

For surveyors, the hit was especially hard because our industry doesn’t just rely on the housing market, but also on commercial and retail expansion, which depends on the public sector to build infrastructure like new roads, sewer outfalls, parks, schools, airport expansions and industrial parks.

When things got bad, many surveyors began discounting their services in an attempt to hold onto their clients and market share. Over the past three years, for example, I have seen the fee and value of ALTA surveys – surveys required by banks before they will refinance a loan – sell for half of what they did before the fall.

The irony is that as the economy slowed, interest rates began to fall and investors, shopping centers and businesses began to refinance their properties. The need for ALTA surveys actually grew as a result! It was only a matter of months before attorneys representing banks began calling our firms asking for “ALTA updates,” implying something other than a new survey.

The firms of the future will be smaller with fewer permanent staff. Fees will change. It will no longer be just about how many crews you have, but how smart you are at collecting and selling 3D data. And those firms that can find ways to use existing sources of 3D data will be even better equipped to weather the storm.

For survey firms – as is true for all industries in this economy – the way to survive is to simply be a better businessperson. Here are six important things every business can learn from the surveying industry:

#1: Control your price. There are only two ways to control your prices: have a healthy backlog of profitable work and provide valuable services to your clients.

#2: Utilize subcontractors. Have a permanent staff large enough to process the workflow and provide quality control, but maintain relationships with good subcontractors and associate firms to expand your workforce when you have a wave a work that your permanent staff can’t handle.

#3: Make profit your goal – not billing. Just because you bill a crew out at $1,000 doesn’t mean you make $1,000. Your actual profits are typically closer to $150.

#4: Don’t buy – rent, swap and borrow. If you can rent a piece of equipment for $500 and make $150, you have greatly reduced your cash flow and improved your profit margin. Take a look at all of the expensive equipment you have purchased and must pay for every day. Unused equipment sitting on the shelf is not a good investment. Swap with other firms when you can, rent when you have to, and buy when the workload demands it.

#5: Always have a contract. Make the signing of a contract the starting point for every job. Even with an established client, having a signed contract can save a lot of scope creep and misunderstanding even on the simplest jobs.

#6: Don’t cut your price without changing the scope. Many lawyers have called to tell me that my price is too high. I remind them that it’s less than their price and they don’t even have to leave the office!

Lastly and most importantly, be realistic. If your workload goes down, you must cut your overhead immediately. For most of us, this means staff, which is always the hardest thing to do.

At one point, we had to reduce our employees from a high of 45 to just seven. We have since slowly built back up, but it was this reduction in staff, combined with tight cash management and a realistic outlook, that enabled us to survive.

The key to surviving this economy – for land surveying firms, as well as all business – is to be realistic, creative and adaptable. This is what it will take to survive and grow into better times.

Honor for me to recommend LandAir Surveying Company

It is a genuine pleasure and honor for me to recommend LandAir Surveying Company, a land surveying firm with whom we have worked for many years, on over a dozen projects. Their work has been a major factor in our company’s continued success in the transportation design industry. LandAir has proven consistently that customer need and company profit are not mutually exclusive.

During LandAir’s service with us, I interacted frequently with several key members of their staff, and depended on them to meet project schedules, benchmarks, and deadlines. LandAir is the first company we go to when we need land surveying services. They are very goal oriented as well as team players. LandAir has always been a pleasure to work with.

Tate Jones, President and owner, has demonstrated from early in our dealings with him that he understands what business is all about. He is well organized and quite aware of the bottom line. He is driven in equal measure by both quality and efficiency.

In closing, let me say I have no hesitation in recommending LandAir. I feel confident he would be an asset to your organization.

P.E. Vice President
