Frequently Asked Questions
Although all projects are unique, these are some of the questions we hear regularly. Our office staff is experienced and prepared to respond to your inquiries. Please contact us by phone or e-mail for prompt and thorough answers to your job questions.
Q: Is there a limit to the size of the cuts?
A: Bluegrass has been cutting concrete and metal with diamond wire saws for over 30 years. The largest rock cuts were 10,000 ft2, the largest concrete cuts were 7,500 ft2, and largest solid metal cut was 12’ diameter. Each job is unique, and we customize our approach by using a variety of cutting technologies, equipment, and skilled operators.
Q: What types of metal do you cut?
A: Inconel, zinc, copper, bronze, stainless steel, ferrous steel and other exotic metals.
Q: How quickly can Bluegrass get a quote to me?
A: It depends on the scope of the project and detailed plans provided by the client, but typically within 8 hours.
Q: What is the time period for mobilization?
A: For jobs without extensive customization, Bluegrass diamond wire saws and/or robotic hammers and technicians can be mobilized in 24 hours or less.
Q: How much noise and vibration can be expected when cutting concrete with a diamond wire saw?
A: Under most circumstances, the only sound is the electric saw motor, and there is no vibration associated with the concrete cutting operation.
Q: Can diamond wire saws be deployed underwater?
A: Yes. Diamond wire saws are versatile in all environments: on land, over water, and subsea.
Q: Can the existing rebar be saved when using Brokk robotic hammers?
A: Yes. Bluegrass technicians are highly skilled and experienced Brokk operators, able to perform concrete demolition with surgical precision which allows clients to reuse the existing rebar and dowels.
Q: How much water is needed on diamond wire cutting projects?
A: Diamond wire sawing generally requires 1 – 1.5 gallons per minute in order to cool the wire and eliminate dust.
Q: Are Bluegrass personnel trained for and experienced in nuclear work?
A: Yes. We currently have 25 experienced technicians who have completed the commercial nuclear training and security requirements, and have obtained unescorted badges.
Q: When cutting radioactive concrete, how is the slurry and wastewater handled?
A: In a nuclear environment the wastewater is usually vacuumed into receptacles where heavy particles settle to the bottom. Using submersible pumps, the turbid water is reused in the cuts thereby reducing the overall volume of contaminated water by up to 80%.
Q: What are the advantages of shaving concrete vs scrabbling concrete?
A: Shaving concrete allows for precision removal to exacting depths, produces a smooth final surface which allows for direct scans and surveys, and reduces overall waste volume by 50% or more.
