Information and Definitions:
The Concrete Cutting Industry is very unique and has many terms and phrases that are used to describe certain aspects of our expertise. We at Cal West Concrete Cutting, Inc. believe in obtaining as much information as possible, prior to estimating or starting work on any project. Gaining accurate information about the job and conditions allow us to provide you with accurate cost estimates and minimizing any chance of cost over runs. It also gives us as a team, the confidence to approach construction projects with the knowledge and professionalism that is absolutely essential for both of us to remain leaders in today's aggressive construction market. Listed below are some of the work definitions we believe to be helpful in preparing estimates and job description.
Where two cut lines intersect bordering the perimeter of an opening or area being saw cut. These over-cuts are caused by the radius of the saw blade and vary depending on the depth of the material being cut. In order to cut completely through the material at a corner, over-cuts are necessary. However, if the over-cuts are of a structural or finished product concern, there are alternative methods of cutting corners square without over-cuts but that requires additional equipment and cost.
Line drilling is generally utilized when over-cuts are not permitted or when a small opening is needed in a relatively thick wall or slab. Sometimes openings have to be cut adjacent, or up against a vertical surface, which will not allow for any over-cuts. A series of round holes are drilled and connected to isolate the interior portion being removed and then the webs created by the radius of the cores are chipped away. Alternate equipment for some projects may include Chain Saws, Ring Saws or Wire Saws depending on which application is best suited for the situation.
Sawing Footage vs. Trench Footage:
A common error in providing accurate cutting footage is using trench feet instead of lineal feet of actual cut. Most trenches require cutting on both sides for removal where the pipe or conduit run going back in is figured in down the center of the trench, one way. Normally, we have to cut on both sides of the trench, so when figuring a trench that is 500' long, a cut on both sides would add up to 1000' of cutting plus end cuts and cross cuts if needed. Whereas, a single pipe going back in would only be 500' of pipe.
Cross Cuts are made across a trench, slab section or wall section to help expedite the removal of the material for various reasons. Generally, these cuts are made and are part of the demolition portion of the quote provided unless specifically requested by the customer who may be doing their own demolition or removal work.
Pick Holes are holes drilled through a piece of material being removed so that forks from a fork lift, eye bolts or chokers for a crane can be inserted to lift or lower the section safely to the ground. These are generally used on suspended slab sections or wall sections in remote, confined or high areas that cannot be safely dropped to the surface below or demolished in place.
Gas Slab Sawing vs. Electric, Pneumatic or Hydraulic
For most projects, Gas Slab Sawing represents the most effective and economical way to do the job as they range in horsepower from 5 to 72 H.P. If the work happens to be in an area that is heavily congested with inhabitants or is inside a building or structure, a gas saw probably is not suitable due to the emission of carbon monoxide gases which can be dangerous and deadly. In such areas, electric, pneumatic or hydraulic powered equipment is the proper alternative, depending on conditions and access. Always consider the work area and restrictions that may exist and if you have any questions on which tool is the right tool, please give us a call to discuss the solution. Cal West has experienced estimators and field personnel that are totally qualified to make those decisions and with our wide range of equipment, we can meet any requirements.
Access to Work Area:
Although access to work areas may seem easy when just walking to them, getting tools and equipment close may be another story. Some projects require special tools or power packs to run the equipment so always consider the distance to outside access for stringing power cords, air and water hoses or hydraulic lines. Their relationship to foot or equipment traffic has to be considered so they aren't a liability in high traffic areas.
Most hoses are small and can be strung above and through tight areas and small openings to gain access to the outside. With our array of available power sources and equipment, we often can keep the power source close to the work area with minimal cords or hoses running to outside sources.
Noting these few terms, phrases and conditions will make it much easier for you to provide a Professional Concrete Cutting Contractor with the information they need to give you accurate proposals and man your jobs with the proper equipment. Hopefully, you will give us the opportunity to provide you with both.
