Rethinking Old Methodology

WC Contracting Solves Excavation Challenges with New Technology

By Richard Rybka

Daniel Childs is one of those fiercely independent men who choose not to “color inside the lines”. His definition of success is more philosophical than economical. Childs’ path revolves around using his talents and passions to operate a contracting business that he can enjoy, day in and day out.

At the same time, his operations need to generate sufficient revenue to sustain his equipment and provide income for his family. Childs walks a fine line, maintaining a balance between his personal vision and harsh financial reality. He is constantly seeking a way forward.

Challenges of Launching WC Contracting

Childs made a vital business decision 15 years ago. He decided to start WC Contracting Inc., a multi-service grading and excavating company out of Cape May Court House, New Jersey. To have full control over his company’s operations and destiny, Childs runs his enterprise as the sole employee and machine operator. But there is one major hurdle to this business model that he had to overcome.

This is a pile cap dug with a standard Steelwrist
16” trenching bucket. What you see was dug
entirely with the machine from pretty much one
position. iDig was used for depth but
unfortunately not in the picture. This job would
be formed so it is over dug and standard bucket
could be used

As an operator digs, he needs to know how much material to remove. Typically, a worker enters the excavation with a grade rod. Another person takes a reading through a construction level. Calculations are made to determine if the bottom is “on grade” or if more material must be excavated. Manual grade checking presents a major complication to a one-person operation. It also presents a potential safety risk.

Depending on the configuration, special OSHA requirements must be met before a person can safely enter an excavation. These additional measures can be time-consuming and add extra cost to a project. Eliminating the need for a grade checker would allow Childs to work solo and eliminate the cost of an additional employee. He needed to find another way to make sure he was digging accurately.

Searching for a Solution

For the past 15 years, Childs has experimented with a variety of tools, techniques, and technologies that would enable him to work solo and simultaneously check grade. He looked at every available option as grade checking devices came on the market. 

Never satisfied with the results these provided, his desire to take full advantage of current technology was always at the forefront of his efforts. This pursuit finally led him to the iDig system. He resolved to further explore this option.

Deciding to purchase a new piece of equipment based on advanced technology is not always easy. Will it perform as advertised? Will the improvement in my day-to-day operations be worth the cost of investment? These are common questions contractors ask themselves. Are there any ways to gain reassurance before taking the plunge?

Purchasing from a reputable dealer is one way to ease purchase anxiety. Requesting an on-the-ground demo is another. Jim Hardman, President of Eastern Laser and Positioning, and Drew Williams, Inteq Territory Manager, set up a trial system on WC Contracting’s machine. This extra level of pre-sales support facilitated Child’s decision.

“Jim is clearly interested in not only selling the product, but in my success with the product,” Childs explained. “They were both willing to take whatever time I needed to be comfortable with the system. I know that I will be well supported with any needs that arise.” 

Features and Benefits

iDig is an accurate grade checking system. A touch screen display, mounted right in the cab, enables an operator to see the bucket of his machine in relation to surrounding surfaces. A light bar with red, orange, and green LED’s shows the operator when the bucket teeth are “on grade”.

The light bar is positioned in the operator’s working field of view. He can easily watch the movements of the bucket and simultaneously obtain visual grade information. The need for a grade checker is eliminated. 

The display and light bar are only part of the unique iDig system.

Three external sensors are mounted to the bucket, boom, and dipper. A fourth sensor is located inside the cab to account for chassis pitch and roll. Solar-charged batteries power the sensors, eliminating the need to plug into a 120 VAC outlet for charging. The system operates wirelessly by radio, so there are no cables to connect. Wireless operation provides several benefits.

“No running of wires from the cab out the arm, or worse removing them once they’re all greasy. No wires for a branch to snag on,” Childs explained. Communication cables can easily be damaged in the type of work he does, and connectors can become clogged with dust and dirt. Eliminating them altogether adds to the reliability of the system.

The iDig system is designed for portability and ease-of-use. Quick-connect cradles for components reduce the amount of setup time. Once the system is installed and calibrated on a particular model machine, the configuration is saved for future use. One iDig system can be deployed on any number of excavators. Swaps can be made quickly and do not require technical personnel.

Success is Measured by Workflow Improvements 

Childs used a tripod-mounted laser transmitter with a machine receiver mounted on the excavator arm before purchasing the iDig system. Keeping a clear line of sight while moving around a foundation dig was always a problem.

Childs commented on the improved workflow he now experiences. “I used to have to get the laser tripod at just the right spot and dig in the right order so that the machine was never between the receiver and transmitter,” he explained. “As jobs get more complex, this gets harder to do and causes you sometimes to have to dig yourself into a corner or do multiple setups.”

Because the iDig system does not rely continuously on a laser reference while digging, this problem is totally eliminated. Childs continued his explanation: “If the excavator will be relocated during digging operations, the receiver on the arm only needs to be rotated into the laser beam once. The system will then be on grade for any digging that can be reached from the new location.”

Job Setup is Easier

Setting up for a new job site is one of the most challenging tasks for an excavating contractor. An error in grade calculation can easily result in over-excavation or costly rework of finished grade to meet plan requirements.

“The setup on the iDig is quicker,” Childs said. He continued: “I can build the grade for the job right on my hand grade rod from the benchmark given and the requirements of the prints. Once I have that set, I just take the total distance from the bottom of the rod to the center mark on the hand receiver and enter that into the iDig system.”

Old habits die hard. Childs finds himself double-checking the iDig readings using his grade rod. The system has proven itself trustworthy. “I have also enjoyed a new experience for me, using the system to check grade without having to set up the laser when there are physical benchmarks within reach,” he said.

Specialized Foundations Present Tough Challenges

WC Contracting serves an area along the Atlantic coast and includes barrier island towns from Cape May to Atlantic City. Because of direct access to the ocean, this area is popular for high-end shore homes. 

Shore homes are built on sandy soil, subject to high winds, and prone to flooding. Conventional dug foundation walls are not feasible for these conditions. Typically a wood pole piling and grade beam design is used. It is an excellent structural system for the local conditions, but a nightmare for an excavation contractor.

wood beam installed to carry the deck joists.

Pole spacing is typically 5- to 6-foot on center but sometimes can be as close as 3 feet. This grid creates a maze of obstacles around which as much as 36 inches of material needs to be removed. Excavation under these conditions requires focus and trust in the machine’s capabilities.

When machine trenching around the pilings is completed, the result resembles a series of interconnected rectangles. According to Childs, getting to this point usually takes one and a half days, and the excavation work is close to 95 percent complete. A few laborers can clean up material around the poles in less than an hour.

The iDig system shines under these types of conditions. Checking grade with a rod in so many different locations would be time-consuming and labor-intensive. Once the system is set up for the job, no further checks are needed.

5 Modern Capabilities that Optimize Field Operations

Travis Parigi, CEO of LiquidFrameworks

Field operations are behind when it comes to utilizing digital tools for the workforce. However, updated technology empowers managers to track and oversee operations at unparalleled levels in new environments. These updates can also provide an abundance of choices related to improved technologies like using smartphones, GPS, RFID, On-Demand/Cloud Computing, barcodes, scanners, and the latest generation of tablet computers. The modern capabilities of technologies can ultimately help both management and workers optimize operations while in the field. 

Nonetheless, the constant change of technology brings with it the rise of questions for operations management, such as…

  • What is the most valuable data?
  • What is the appropriate approach to utilizing technology?  
  • Which will deliver the biggest “bang” for your buck?
  • How do you integrate different solutions and data into an operations flow?
  • How do you entertain various personnel skill sets and ensure adoption by field personnel? 

It is first important to identify critical considerations when assessing new electronic solutions or field service providers to optimize field operations.

1. Paperless Ops

The most apparent opportunity to update implementation is through shifting to an electronic platform for operations or adoption of solution elements. This approach is coined as going paperless. This method initially just scanned identical electronic copies of paper items such as service tickets or delivery receipts. Overtime data has advanced to capture documents to be represented and reported on devices. Both of those methods are valuable but only represent a fraction of the value that comprehensive field operation solutions provide. Elements of a complete mobile field operations solution include:

  • Fully Electronic/ Error Reduction
    • Every time a field operator produces a piece of paper documentation and sends it back to the office, at least $10 in processing costs are generated. Problems related to legibility, re-entering data into electronic systems, errors in the system and issues integrating paper with customers all contribute to added delays and costs. Modern solutions promise optimal speed and leverage through structured data representation. This allows field-generated data to be efficiently and effectively fed into back-office systems and presented to customers.
  • Configure vs. Capture/Validation/Rules
    • Solutions, such as scanners or pick lists, only capture documentation and often fail on several levels. Lack of internal logic and error prevention reproduces paper problems in an electronic format. It’s crucial for field operation solutions to properly validate data and prevent invalid configurations and data entry. AI functions, such as rules and knowledge base are invaluable. This is exemplified by solutions that either use configuration engines to take users through job set up steps or automatically configure based on job conditions or equipment.
  • Customization
    • It is also key for all platforms to flexibly capture elements of an operations flow, organization, or government/customer requirement. For example, when altering the location and appearance of screen elements to attached data entry points, the solution should be configurable to both your company and industry.
  • Data Availability
    • A solution must satisfy customer process demands, including customer signature, emails, and approvals. Data captured through the solution should then be available to your back-office systems and email.

2. Properly Modeling the Process

Possibly one of the most important factors in improving operations includes structuring electronic data into elements to ensure efficient scheduling, fulfillment, and analysis. First-generation field operations solutions made individual process elements such as field tickets or dispatch orders electronic. This approach is valuable but falls short in capturing the relationship between resources that allow for optimal planning and utilization. 

For example, the value becomes limited when the technical equipment is dispatched without the system attaching associated personnel and consumables. An ideal solution is not only aware of these associated items, but also recognizes locations, readiness level, and suitable, available replacements. Once these elements are in place, operations managers can then plan immediate operations and begin to prepare future consumable, maintenance, personnel, and other resource requirements.

3. Flexible Standardization

All platforms must pave the path for best practices to be overlaid on the solution while also remaining flexible enough for operations to continue remotely. Tools and technology that simplify workflow are essential. 

Tools

  • Data
    • Full access to data by field personnel allows operations to be executed even if the back office is unavailable. Access to the master data and configuration specifications enables single-entry without costly “fix-up” by personnel. Updated, accurate pricing also allows for improved customer coordination and minimized approval delays.
  • Rules Engine
    • Rules engines meaningfully supplement individual worker knowledge and enforce standards. This capability automatically recaptures previously lost or unbilled items, prevents unsafe configurations and allows personnel with less experience to perform complex operations. Rules engines also secure corporate knowledge as a key backup function for senior personnel.
  • Collaboration
    • Field workers and back-office personnel should work together. Whether you are enriching tickets with notes or requesting back-office involvement, collaboration capabilities of mobile field operations platforms are essential.
  • Workflow
    •  A solution must provide mechanisms to standardize workflow such as a customer approval process or uniformity of ordering equipment.
  • Integration
    • Solutions should integrate opportunities with electronic systems. An Open API makes it simple to seamlessly consolidate with existing systems.
  • Additional Documents and Forms
    • Companies often have additional documentation specific to their industry or organization, some of which include Job Safety Assessments and logs. Although electronic solutions do not come “out of the box” with the exact document, customization easily captures this information.

Technology

  • Smart Client
    • Even the best communication environments experience problems ranging from equipment failure to shielding and capacity issues. These bumps in the roadblock require communication from outside sources. These scenarios require autonomous solutions that flexibly reestablish communication and transfer data.
  • GPS/RFID
    • Solutions should provide technology integration points like GPS or RFID.
  • Attachments
    • Reference documentation, such as videos, procedures, and manuals, prove useful in field environments.
  • Leverage Existing Assets
    • Mobile field operations solutions should easily integrate with established IT systems, such as accounting and payroll. 

4. Effective Analysis

Effective analysis is key to optimize field operations and is part of a mobile field operations solution. The ability to measure production details and to generate custom reports is vital to company success.

  • Measuring
    • Demands of on-field personnel and floods of data lead many organizations not to capture the full extent of what happens during operations. For instance, a performed service is captured, but the detailed start/stop times, consumable usage, ancillary equipment, and personnel involved are not.
  • Report Generation
    • All solutions should have robust reporting mechanisms that feature a full security model with proper access. The capability to create custom reports is indispensable.
  • Availability and Distribution 
    • Reporting should be available to proper personnel. Web-based reporting solutions provide wide distribution capabilities for users at numerous locations on various devices. Email integration is a fundamental capability for the dissemination of reports, whether that is executed through an incoming-data based alert system or a scheduled distribution list.

5. Involve the Customer

Customer involvement is commonly overlooked when advancing operations and resource utilization. Customers are most involved at the beginning (ordering) and end (invoice approval) of the process, but true value comes in keeping them invested throughout the process.

  • Tracking
    •  Appropriate oversight capability in internal operations can effectively speed approvals and increase customer comfort and satisfaction. 
  • Approval 
    • Mechanisms that grant customers the ability to interact with the field operations solution, whether that be through notification emails or electronic approvals, can also significantly speed up the process.

Clearly there are many considerations to think through when evaluating field operations improvements. As a business leader, recognizing the impact technology will have on your field operations is your cue to initiate digital transformation as soon as possible to secure a competitive edge.

Technology Training on Workflow Helps Address the Need for New Workers

By Jeff Winke

It is a scary world out there for you construction contractors who struggle with tight deadlines, demands for regulatory-governed quality, better productivity, lower costs, more time in a day, and that ominous need for a competent workforce.

The Associated General Contractors of America (AGC) released a study of construction firms in the United States.A few key statistics included in their Workforce Shortage Report include:

  • Eight out of 10 construction firms cannot find sufficient qualified employees
  • 19 percent are investing in labor saving equipment and tools that require smarter workers
  • 82 percent believe that it will be more difficult to find qualified workers over the next 12 months

“As the U.S.-based construction workforce becomes increasingly thinly spread,” the AGC report stated, “owners and managers of construction firms will be required to approach the problem of labor shortage creatively, in order to convert these problems into opportunities. A key to overcoming the labor shortage, in the construction industry, is to invest in current employees to increase their skills, knowledge and abilities, as well as to support existing employees with labor-saving tools and equipment.”

Investing in existing employees has definite advantages, when compared to hiring new employees.

  • Current employees know how the company operates and manages its project sites. 
  • Current employees are a known entity. Managers know their strengths and weaknesses and may be better able to manage and lead them than new hires.
  • With new employees, there are start-up administrative costs, drug testing, equipment and safety training, and general acclimation to new managers, co-workers, and procedures. 
  • Current employees pose less risk. Studies have confirmed higher injury rates among workers who have been on the job for less than a year. Consider also that hiring new employees with less experience and then moving them quickly into the field to meet demands may create greater risk.

Clearly, on-going skills and technology training of existing employees can prove to be critical not only for retention but the success of the company.

“The penalty for not keeping current with technology is longer project timelines,” stated Ron Oberlander, Vice President, Global Professional Services, Topcon Positioning Group, Livermore, California. “Successful training focusses on the work process which yields greater efficiencies and better results.”

An Emphasis on Workflow

With the training emphasis on workflow, employees can develop a broader perspective on construction projects and all that goes into the tasks that culminate in their completion. The emphasis on work processes demonstrates a respect for the intelligence of employees and invites them to think in a partner role, which can strengthen their commitment to the job and the company.

“I’ve completed a couple of training programs conducted by Topcon and I am scheduled for another in the next six months,” said John Poirier, Project Manager with Warman Excavating & Trenching Ltd., Waldheim, Saskatchewan, Canada. “It is well worth the time; and the cost is inconsequential compared to what I learn. Unbelievable trainers, seasoned experts with 20 to 30 years of experience, are training me. They know the products, the market, and understand the workflow.”

“Technology changes too frequently,” said Oberlander.”When we host attendees – distributors and end users – at our training sessions we focus on workflows and how the key features of our products and systems improve the productivity and efficiency of end users.”

With the strong job economy today, it is sometimes difficult to find talent to fill open positions.A benefit of training and the power of easy-to-use technology means that contractors can hire less-skilled talent.They can either send them to instructor-led courses or put them through e-learning-based training.Either way, the knowledge and skills gap can be bridged.

Technology Evolution

Since every construction project is unique, and may require different technology and solutions, it is important – actually imperative – that workers at all experience levels engage in training regularly to remain up to date.

“Think about the advances in consumer technology such as the Apple iPhone,” Oberlander said, “The innovations and high-powered processors that upgrade the iPhone annually are being used in construction equipment. Look at the displays and systems inside of a new excavator, dozer, or other heavy equipment which now make them more productive to run and service; and in turn, makes the contractor more efficient and profitable.”

Oberlander went on to describe how GPS machine control has evolved during the past 20 years from little adoption of machine automation to a market where some machine manufacturers are integrating machine control technology direct from the technology-provider’s factory floor into their machines or even wiring heavy equipment so that they are capable of later adding aftermarket systems.Some government agencies are even specifying that contractors working on their projects must employ GPS machine control on their equipment.

An Investment in Training

Topcon Positioning Systems’ current project is an example of the interest and commitment to training occurring in the construction industry. The company is investing by building state-of-the-art training facilities in the United States, Italy, and Japan. 

The new 6-acre training facility in the U.S. is being constructed at the Topcon campus in Livermore, California, and will cover training for construction, geo positioning, and paving. Vertical construction and layout training will include a half-built building for real-world demonstrations. Two state-of-the-art classrooms will be included. The training facilities in Italy and Japan are being built to the same parameters.

“Since we focus heavily on workflow training, our training will mimic live applications that take place at a typical construction site,” Oberlander said. “The main difference is we can focus on the application and training without distractions of a contractor’s live jobsite. We always offer on-location training at the contractor’s jobsite or home office, but we believe that it is important to establish a baseline of education with a contained workflow at our training center.We also offer the students a tour of our manufacturing facility so they can see how the products they use are made.”

Construction contractors struggle with the need to keep up to date on the latest technology and trends that make their projects more efficient, while attracting and keeping a full workforce in a tight labor market. The answers may be found in training both existing employees and new inexperienced workers on labor-saving technologies with a focus on the work process which yields greater efficiencies and better results.

What do you tell others considering training? Poirier said: “Go for it. There is 100 percent benefit to training; otherwise you’re looking at your technology being the world’s most expensive paperweight. Training gave me knowledge and confidence to feel comfortable with the technology. I recently set up a new excavator using a system I had mounted on a different machine. It works great and would have cost me $42,000 to have someone come in and set up and initialize the GPS system on the excavator – all work I did myself.”

Clearly training can benefit contractors. It can add knowledge, skills, and the confidence to succeed.
