Supplying defense contractors with critical equipment and parts is a challenging role that HCL Logistics, Inc., of London, Ontario has been fulfilling for the last eight years. Handling about 26,000 SKUs that include everything from tiny washers to 20-foot-long steel sheets to complete engines, the company supplies key components that its customers use to manufacture land-based military vehicles used by Canadian and allied forces around the world.

In 2012, HCL Logistics found itself in need of a more efficient and streamlined warehouse operation. Intent on improving its flexibility, efficiency, and accuracy in its 500,000 square feet of warehouse space, the company shopped around for an automated solution that would help it achieve those goals.

“We have one major customer in the defense industry that we service, and we had recently won a larger contract that was previously being handled by a different provider,” says Tim Van Holst, president. “We were using conventional racking systems in our warehouse, and felt that new equipment like narrow-aisle racking and vertical lift modules would help us get to the ‘next level’ with our contracts.”

In this article, we’ll look at the challenges that HCL Logistics was grappling with in its warehouse, tell how the company selected its providers and equipment, and outline the benefits that the company is seeing from its investment in automated storage and retrieval system (AS/RS) technology as part of a larger material handling strategy.

Searching for a Better Way
Since inception more than eight years ago, HCL Logistics has been providing warehousing, transportation, and just-in-time delivery in a secure defense environment. Like many growing companies, HCL Logistics reached a point in 2012 where its existing warehouse setup was no longer meeting its needs. Rather than simply laying new pieces of equipment or software on top of the problem, the company went in search of a strategic, end-to-end material handling solution.

Van Holst says the initiative was driven by the need for better picking efficiency and improved material and people flow on the warehouse floor. “With the way the warehouse was laid out, we were moving large products (i.e., vehicle engines) long distances for staging and shipping,” says Van Holst. The company also wanted to reduce the number of forklifts on the warehouse floor, improve picking accuracy, and create a more streamlined process overall.

As a starting point, HCL Logistics considered narrow-aisle racking systems that would support its efficiency goals. Working with Brian Rodway of Johnston Equipment, the company also explored the material handling and AS/RS options on the market. During the selection process, Van Holst says the company also had its eye on maximizing its current warehouse space, better utilizing the facility’s vertical space, and installing equipment that could be used to batch multiple orders for different customers.

“We started by integrating narrow-aisle racking and that led to our testing vertical lift modules and then moving to radio shuttles,” says Van Holst. “We wanted a complete solution that would integrate these various components into a more streamlined setup.”

The Right Solution
In 2012, HCL Logistics test piloted two Kardex Remstar Shuttle XP Vertical Lift Modules (VLMs). Automated high-bay warehousing systems with modular designs that operate on the "goods to person" principle, the VLMs handled the kitting portion of a specific customer’s contract. “Once the two units were installed, we used a ‘wait and see’ strategy to see how they would work for us,” says Van Holst, who began to notice positive results soon after installation. Automating a manual picking environment, for example, has made employees 10 times more efficient and data entry control nearly perfect.

“Based on the efficiencies and the space savings that we gained, we grew the system from two units to 21 VLMs,” says Van Holst. Combined with a high-density pallet system and narrow-aisle racking, the setup also cut HCL Logistics’ required warehouse space down by about 100,000 square feet. In one section of the facility, for example, the company saved about 30,000 square feet simply by installing the VLMs that now take up just 1,000 square feet of space.

To round out its end-to-end solution, HCL Logistics also installed a radio shuttle system that it uses to move large items that once required much navigation and logistical coordination. “Our radio shuttle is positioned about 30 feet away from our receiving area,” says Van Holst. “Our larger products now occupy a 4X4 skid, which equates to about a 50% space savings for the area where we store our larger materials.”

More Efficient Client Handling
When shopping around for a holistic warehouse solution four years ago, HCL Logistics wanted a platform that would help it better manage the small parts that it was handling on a day-to-day basis across multiple customers. More specifically, it wanted to be able to take parts that had to be kept separate while on the shelves and batch them during the picking process.

HCL Logistics found what it was looking for in Kardex Remstar’s Power Pick Global inventory management software client handling module. “With fixed, static shelving, you basically dedicate aisles to different customers and then move through the various zones to pick orders—even if the armed vehicle parts are the same across those zones,” Rodway explains. “With client handling, HCL Logistics was able to keep each customer’s inventory separate, but not physically separate. That allows them to get the benefits of storage density in their VLMs.”

This capability also helps HCL Logistics expand its customers’ material profiles without the need for additional, physical shelving space. Instead, it can simply define more trays for a specific customer, and within a certain tower. “It gives them flexibility and agility to grow,” says Rodway, “and makes it much easier to serve multiple customers.”

Measuring the Results
From its investment in an end-to-end automated warehousing solution, HCL Logistics has gained a state-of-the-art warehouse environment that includes vertical space saving storage systems, modern condensed racking systems, wireless handheld scanners, and a real-time inventory management system. “Our goals of flexibility, efficiency, and accuracy have been met and exceeded,” says Van Holst, “and we are now well positioned for growth and expansion into new markets.”

HCL Logistics has also exceeded its picking efficiency goals and is now fulfilling orders much faster than it once did. “We’ve seen a 15% efficiency improvement as a result of the VLMs and the wire guidance system that’s incorporated into them,” says Van Holst. “For large products, the radio shuttle system has doubled our efficiency in terms of shortening up the amount of driving and material-handling time.”

Other key gains include inventory accuracy improvement—from a previous 98% to a current 99.5%. Cumulatively, Van Holst estimates that the solution could potentially save the company $3 million a year on adjustments and inventory alone. “It’s not just about the picks, puts, and inventory accuracy,” says Van Holst. “Cycle counts and physical inventory are also much faster now.”

Finally, he says HCL Logistics’ employees are now working in a safer, cleaner, more ergonomic environment and it’s a benefit that can’t be overstated. “When you’re storing this volume of parts for so long, it’s easy for them to gather dust and for labels to become unreadable,” says Van Holst. “With our new system, the overall cleanliness of the facility has definitely improved.”

Keeping it Simple
As he looks around HCL Logistics’ warehouse today, Van Holst is pleased to see that all parts and equipment have their designated “spaces” and that the flow of material through the facility has become more streamlined, organized, and predictable. To other companies considering a similar, end-to-end approach, he says, “Keep it simple at first and test out the strategy; then grow from there.”

In sticking to its “keep it simple” philosophy, HCL Logistics was also careful not to overcomplicate its new, end-to-end warehouse management strategy. Within its 21 VLMs, for example, it stuck to just a few different bin sizes in order to keep the process manageable—and to make sure it wasn’t wasting any tray space. “We didn’t want our operators looking through 120 different bins to try and figure out where to put something,” says Van Holst. “Even though we’re dealing with complex, state-of-the-art AS/RS machines, when it comes to the setup and binning, we kept it as simple as possible and it has paid off for us.”
