The new headquarters of Cold Spring Granite Co. in Cold Spring, MN, was awarded LEED Gold certification from the U.S. Green Building Council (USGBC) in December 2008. One component to the building’s LEED certification is the use of 70% local stone from Cold Spring Granite’s own quarries within 250 miles of the project site. Further contributing to the green design, the canopy at the outside entrance is formed by a crane that was once used at the previous downtown industrial site. 


For more than a century, Cold Spring Granite Co. has operated as a leading stone producer in the U.S. The company employs close to 1,000 people in five manufacturing locations and 30 quarries located throughout North America. As it evolved through the years, Cold Spring Granite has maintained a practice of preservation with respect to the environment. Recently, it further committed to being green by building a new 22,500-square-foot headquarters in Cold Spring, MN, which received LEED Gold certification from the U.S. Green Building Council (USGBC) in December 2008. Additionally, Cold Spring Granite continues to strive to reduce energy, waste and cost in its quarrying and fabrication processes - overall making for a more efficient operation.

“This is not a culture change for us,” said Ray Jaeger, Engineering Manager at Cold Spring Granite. “I have been with the company for over 30 years, and we are always looking for ways to reduce energy, water use, waste and ultimately cost.”

The new headquarters features a “white” roof, which was part of the LEED certification. A total of 77% of the roof is comprised of a white aggregate ballast material and white skylight having a Solar Reflectance Index of 105 SRI value (low slope) and 100 SRI value (steep-sloped). A patio area has also been set up, which allows employees to get some fresh air on nice days.

The new headquarters was designed by Miller Architects & Builders of St. Cloud, MN, with extensive input from Cold Spring Granite employee teams. “As is typical with our company’s open culture, employees were involved in every aspect of this new building’s creation,” stated Jaeger. “Employee committees helped guide our efforts, providing feedback on office layouts, design features, stone selection, landscaping and even how far we went with the LEED process. We found that this involvement helped ease our employees’ transition to the new space, as we were making a significant change to the work environment.”

Construction of the new headquarters was part of the final phase of Cold Spring Granite’s consolidation plan to move from its downtown location to the “West Campus” in Cold Spring. The company’s intention in doing this is to increase productivity and create a more efficient and integrated operation. Prior to constructing the new headquarters, divisions were located in separate buildings. 

Among Cold Spring Granite Co.’s three stone-processing facilities on site is its “Thick Stone” plant. The majority of the work done today is thicker slabs and cut-to-size work for memorial and commercial applications.

“Now that we’re in one space, we’ve reduced redundancy and are more efficient,” stated John Mattke, President and Chief Operating Officer of Cold Spring Granite. “The new environment is very positive, and it demonstrates our commitment to creating, maintaining and enhancing a sustainable future.”

According to Jaeger, the company had discussed the consolidation for years, but once it made the decision to do it everything came together rather quickly.

Meeting LEED standards

The new headquarters is a 31% reduction of space from the previous facility. “That was significant to get that kind of reduction with the same amount of employees,” said Jaeger. A great deal of thought and planning went into seeking LEED Gold certification. From site planning, to minimizing water use, optimizing energy usage, indoor air quality, to material and resources for construction, all worked together to accomplish a higher-performing building. Examples include low-pressure water and low-flush toilets in the restrooms to pre-set sensor lighting and temperature control. Additionally, 90% of the space has a direct view of the outside.

One area in the Thick Stone facility is dedicated to the fabrication of stone monuments.

“Our decision was to make an adjustment to our office space - going from a combination of individual offices and high-cube spaces to an open office environment using LEED guidelines,” Jaeger said.

One of the components to the building’s LEED certification is the use of local materials. “We incorporated stone from Cold Spring Granite’s own quarries within 250 miles of the project site. Stone from the old office was crushed and used for base material at the construction site where needed,” said Jaeger. Additionally, CarnelianTM granite with a Diamond 100 finish was employed for the main cladding on the exterior, split-face limestone sills and medallions between the main window sections, and polished RainbowTM granite provides an accent band. Further contributing to the green design, the new building’s front entryway includes remnants of a crane that was once used at the previous downtown industrial site. Also, a large granite wall mural in the front entry was reused from the previous office.

The plant is equipped with a number of state-of-the-art machines such as the Mill5 from Omag of Italy - a numerically controlled stoneworking center with five axes.

A patio area has also been set up, which allows employees to get some fresh air on nice days.

The stone-processing facilities

In upgrading the facilities, the company searched for ways to save on space and produce a better workflow, which resulted in greater efficiency and less energy consumption.

Located on the same property as the new headquarters are various stone-processing facilities. Stone World recently had the opportunity to tour all three operations.

“Thick Stone” facility

Cold Spring’s facility for what they refer to as “thick stone” is more than 100,000 square feet in size. “Initially, it was all about doing monumental work,” said Jaeger. “As a result of our consolidation, we incorporated equipment from the old campus into various facilities within the new campus.”

The Thick Stone facility also houses three Pellegrini RW 2600 robotic diamond wire block cutters. These machines play a key role in the production of cubic work.

According to Jaeger, the majority of the work done today is thicker slabs and cut-to-size work for memorial and commercial applications.

The plant is equipped with a number of state-of-the-art machinery, including the Mill5 from Omag of Italy, a numerically controlled stoneworking center with five axes; three Pellegrini RW 2600 robotic diamond wire block cutters from Italy; and a Thibaut bed polisher from France. The facility also features a designated area for sandblasting. One noteworthy adjustment that Cold Spring Granite recently made was to modify its dust collection system so that it can bring air back into the facility. It has cut energy consumption by 25%, according to Jaeger.

The company’s new set-up for its operation makes it convenient to walk from one plant to another. Stone for in-progress projects is stored in an outside yard. “All the stone in the yard is for a specific job,” said Jaeger.

Slab Tech

A second building on Cold Spring Granite’s site is Slab Tech, which encompasses 30,000 square feet. The plant is equipped with various diamond wire sawing and stone polishing equipment, including three Pellegrini Stone Master diamond wire saws from Italy, two Sun Jin saws from Korea and a LeviBreton KGS polishing line from Breton of Italy.

To give workers a sense of involvement, the company maintains a “Slabbing Tech Center Scoreboard” in the Slab Tech building. “It gives managers and employees a chance to look at how we are doing,” said Jaeger. “It’s a simple tool that allows employees to see what works and what is not working, and they can fix it.”

Additionally, a Predator automated gantry block saw from Park Industries of St. Cloud, MN, is also incorporated into the production process.

Throughout Cold Spring Granite’s office and operations, it has a Quality, Cost, Deliver, Safety & Morale (QCDSM system) in place. The purpose of a QCDSM board is to act as a “scoreboard” for all areas of the office and operations. The QCDSM board should “paint a picture” of the area’s performance. In order to be effective, the scorecard needs to be up-to-date and allow for employee participation.

Thin Stone facility

Cold Spring Granite’s “Thin Stone” facility is housed in an approximate 200,000-square-foot building, and is mostly used for material measuring 2 ½ inches and under. The facility houses 12 Barsanti gangsaws, and the gangsaw “Wet Scrubber” is one of many pieces of equipment that purifies the air in the work environment.

The “Thin Stone” plant houses a LeviBreton KGS polishing line for polishing slabs.

Among other equipment is a 20-year-old Breton polishing line that uses abrasives from Tenax USA of Charlotte, NC. “There are many examples of machines that have gone beyond their expected life-cycle because of our equipment maintenance program,” said Jaeger. Additional machinery in the building includes a Jaguar saw from Park Industries of St. Cloud, MN, and three GMM Lexta 36 bridge saws from Salem Stone of Winston-Salem, NC.

Striving to be more efficient

Just as employee involvement was encouraged in building the new headquarters, Cold Spring Granite also viewed it as a critical component in restructuring their stone-processing facilities. “We made every effort to get people involved with every phase of the consolidation” said Jaeger. And while the company is very pleased with the modifications that have been made in the fabrication plants, it does believe there is still room for some improvement. “The flow right now is intuitive,” said Dan Rea, Senior Vice President of Commercial Group. “We looked at it and said, ‘This makes sense.’ We will have some things to fix, but we are seeing a lot of benefits that we didn’t anticipate before.”

Communication was a key part for a successful transition, according to Rea. “We stepped up our communication and explained why we are doing it,” he said. “People are wearing many hats. Flexibility helps us a lot.”
