Wire Saw Cutting in Grand Rapids, MI

Wire saw cutting in Grand Rapids, MI, is the most efficient way to remove large concrete structures or make openings in thick walls. There is virtually no limit in terms of sawing depth. Our innovative wire saws are used when space is limited, or the material is especially thick and time is of the essence. Wire sawing in Grand Rapids, Michigan provides safe clean cuts and allows for non-percussive, vibration free demolition in sensitive areas like power generating stations, hospitals and occupied buildings. Additionally, wire sawing is used on bridges, beams and piers and anywhere the surrounding areas are vibration and shock sensitive. 

Proven knowledge, five decades of experience, immediate availability, safety, on-time completion and continuing innovation makes Diamond the sensible choice for wire sawing services.

Client

Nuclear Generating Facility—Electric Power Company, North America

 

Project

One of the largest electric power companies in the United States, needed to gain access to two existing 36 inch pipes, buried under nine feet of solid concrete, in order to attach 90 degree fittings in one of their nuclear plants. They also needed to provide clearance so a worker could fit between the two 36 inch pipes to install the fittings.

 

Process

Due to the massive amount of concrete to be sawed and removed— over 16.8 tons, Diamond used a combination of core drilling and wire sawing which allowed the concrete to be cut into pieces, and provided a method for easier removal of the concrete. In addition, the plan allowed for strict adherence to OSHA, NSD, and CSDA Health and Safety codes.

 

Outcomes

“This was a major concrete removal project that had to be accomplished in a short period of time.” said the Senior Project Manager in charge of the project. “The pipes were almost inaccessible—buried deep under very hard concrete. The detailed plan and the process that Diamond developed and followed provided us with the results we needed. From planning, to technical and implementation —they did an exceptional job in the completion of this project.”

Client

Big Rock Nuclear Facility — MOTA Corporation and Consumer’s Energy — Charlevoix, Michigan

 

Project

Consumers Energy’s Big Rock Point Nuclear Power Plant was the first commercial nuclear power plant constructed in Michigan and the fifth in the United States. When the company notified the Nuclear Regulatory Commission, that Big Rock would permanently cease operations, it needed to saw and remove the reactor vessel walls into 16 large blocks for removal by overhead crane. This was necessary in order to provide adequate room for the subsequent dismantlement and removal of the reactor vessel.

 

Process

Diamond deployed a five-person team equipped with core drills and wire saws. In order to provide access for the diamond wire used to saw the reactor vessel walls several 4" holes needed to be core drilled over 25 feet vertical feet through the concrete. The team then proceeded to saw the reactor walls into 16 engineered blocks for removal. For environmental reasons, all the slurry generated during the sawing and drilling process was contained and disposed of appropriately, helping to reduce the environmental impact and cost associated with the radiological waste. After all the sawing was completed, Diamond's team prepared anchor holes and placed large capacity undercut anchors necessary to attach each piece to the crane for removal.

 

Outcomes

According to Greg Garlock with MOTA Corporation of South Carolina (the nuclear services company), who worked in conjunction with Consumers Energy, “Diamond performed the work as engineered, delivering concrete ready for removal on time and within budget. Diamond’s efficient management of the project, in a challenging environment, was key to its success.”

Client

Leland Olds Station — Basin Electric Power Cooperative — Stanton, ND

 

Project

Basin Electric Power needed to make improvements on their existing coal feed system located under a 200 ton coal storage silo. In order to install the new feed system an opening measuring 15.5 feet by 19.3 feet had to be cut through a six foot thick concrete floor that separated the coal storage unit from conveyors below. Additionally, Diamond had to section an 8 foot diameter 10 foot high steel tube filled with concrete for removal from the coal feed area. The client only had three-weeks to saw and remove the concrete for the installation of the new feed system.

 

Process

Before beginning the work, Diamond visited the site to collect aggregate samples to accurately determine the hardness of the concrete to be cut. Also, because of the conveyor system located below the floor it was not possible to shore the concrete and Diamond engineered a cutting sequence that allowed removal of the 21 pieces to begin at the center of the opening by overhead crane. Because the concrete could not be shored it was important that the cut sequence would allow the floor to support its own weight during the precision demolition process.  On average, each of the pieces cut weighed in at 13,000 pounds and Diamond placed all the anchors for lifting and removal.

 

Outcomes

Working 12 hour shifts, six days a week the Diamond five-man crew was able to complete the work ahead of schedule and on budget. According to Dick Schaffer, Project Manager for Basin Electric Power Cooperative, “There were no contractors in the Dakotas who could provide a workable solution to the challenge. Diamond’s representative visited, reviewed our needs and the work to be completed, and submitted a proposal that made sense. Then their team came and completed the job.”

Client

Devere Construction Company

 

Project

Devere Construction Company needed to demolish an existing concrete building owned by Lafarge North America. The building, located in Alpena, Michigan, was joined to another building which was not to be damaged during the demolition process. The two structures had seven, fifty foot tall, 3 foot-thick concrete pillars in common. Each of these pillars had to be demolished without harming the remaining structures.

Plan

To separate two five story-high buildings that were joined together by a series of three-foot-thick concrete columns.

 

Process

Because of the amount of cutting to be done—1,050 square feet through columns of more than three-feet of concrete—safety was of paramount importance. After careful analysis of the project and client needs, Diamond developed a plan to integrate diamond wire-sawing and core drilling technologies to accomplish the client’s objective. The plan allowed for strict adherence to the Mine Safety and Health Administration codes (MSHA), while safeguarding the structural-integrity of the adjoining, remaining building. The plan also satisfied the need to finish the project within an established budget and time schedule. The plan entailed:

  • Cutting in half seven, 3 foot thick concrete pillars, each 50 feet tall and separating each from an existing building that was to be preserved.
     

  • Using diamond wire sawing technology to avoid transferring potentially damaging vibration to the remaining structures. By isolating the two structures through diamond wire-sawing, conventional demolition techniques could be used on the separated structure without transferring energy to the remaining structure.

 

Outcomes

“We had a tough job ahead of us,” said Brock Johnson, Vice President for DEVERE COSNTRUCTION, a General Contracting company. “There was no way we could hammer this building away without destroying the other building. Frankly, we called Diamond and gave them our problem. After meeting with us, they came back with a plan to solve our problem. The plan worked.” According to Johnson, the professionalism and skill that Diamond brought to the job was outstanding. “Their people aligned with our on-site people. They were real easy to work with and worked hard to meet all of our needs. They finished the job according to plan, schedule and budget. As a bonus, they solved another problem for us by horizontally cutting an old 40 feet long by 11 foot-thick concrete footing. The whole project went like clockwork,” concluded Johnson. “Diamond’s knowledge, quality, service and people were excellent. We could not have done it without them.”
