In this month’s issue…
We discuss the sustainability of Indiana Limestone and available LEED Credits, Ernie sounds off on our order process and we have a new project spotlight. Is there something in particular you would like for us to feature or discuss? Drop us a line @email@example.com
Indiana Limestone Sustainability
Indiana limestone is a freestone, and it is a grainstone of uniform texture and grade that has gained recognition throughout the world as a premier dimension stone. Indiana limestone exhibits no preferential direction of splitting. Therefore, it can be cut or carved in almost limitless ways and in a variety of shapes and sizes. This property allows the stone to be sawn, planed, turned on a lathe, hand cut, or hand carved, so that it meets the requirements from the most basic of jobs or the most demanding of architectural designs.
Indiana limestone is classified by the Indiana Limestone Institute into two colors and four grades. Colors are buff and gray, though color options are available in more subtle variations to match most every project need.
For instance, Indiana Limestone Co., through its different quarries, also offers Full Color Blend, a natural compilation of the full range of buff to light gray shades with subtle veining; Silver Buff, a buff color with subtle silver colored veining in the foreground; and Variegated, an unselected mixture of buff and gray tones with a wide range of grain structure and veining (it’s also a grade).
Grade classifications for Indiana limestone are based on the degree of fineness of the grain particles and other natural characteristics that make up the stone. The structural soundness of each grade of Indiana limestone is, essentially, identical.
- Select – Fine-grained stone, having a controlled minimum of inclusions and veining Standard – Average- to large-grained stone, permitting an average amount of inclusions and veining
- Rustic – Large- to coarse-grained stone, permitting an above-average amount of inclusions and veining
- Variegated – An unselected mixture of the other three grades, permitting both the buff and gray colors.
When specifying Indiana limestone, it is necessary to identify the color and grade re-quired, as well as the surface finish to be applied to the stone. It is recommended that all stone for a project be furnished by a single quarry for the best color control. Indiana Limestone Institute notes that large-scale samples, including sample walls (mock-ups) complete with connections and joint closures, can be helpful in selecting stone color and quality. These sample wall constructions should be pre-planned and included in bid specifications, where their additional expense is warranted.
Indiana limestone is a 350 million-year-old representation of life naturally fused to form a unique building material. Because it is extracted with relative ease, Indiana limestone is an outcrop formation that adds little to the already low energy inputs of its workability. Cladding countless monumental buildings, Indiana limestone has shown that it withstands the tests of time, and when decommissioned, can be reused or returned harmlessly to the earth. Naturally formed Inert – no VOC emissions or pollutants Low energy inputs Durable – lifespan greater than 100 years Eligible for LEED credits
Low Life cycle Costs
Indiana limestone is virtually maintenance free. It requires only occasional re-pointing of stone joints and cleaning, if desired. With minimal care, Indiana limestone projects will serve present and future generations for many years to come.
It is common in restoration projects involving Indiana limestone that the majority of the original stone remains in place for continued use, once the restoration work is completed. Indiana limestone also can be taken from one project and re-used as elements in another building, for landscape stones, perimeter walls, or even as site fill. It’s completely inert; Indiana limestone came from nature and can go back to same. Environmentally friendly production processes.
Since the first organized Indiana limestone quarry opened in 1827, Indiana limestone has been in constant use, making an impact on American architecture. Projects utilizing Indiana limestone, many of which are up to 100 years old, exist in every American city, in many small towns and villages, in Canada, and in every type of atmosphere. Though found in only three Indiana counties, it is estimated that with current production method.

Ernie's 2 Cents...
Once we receive your plans or request for pricing, we will work quickly and efficiently to deliver our best pricing to you. We will deliver our quotation to you via email or fax, whichever you prefer.
Design and Drafting
First, of course is the shop drawing process. Our drafting team will work closely with the contractor and/or architect in ensuring that even the smallest of details are addressed. We believe that this process is vital to the progress of your project and will eliminate potential job site or installation issues. Once the shop drawings have been completed, we will transmit these to you electronically (or hard copy if you are unable to print). These should then be forwarded to the architect or responsible party for approval or any necessary dimension changes.
Once final approved drawings are received, we will then provide you with copies of the setting drawings which indicate piece numbers and placement on your project. From this point forward, all references to elevations, locations on the building, etc. should be made using the setting drawings – this is where the particular elevations, plans and section views as well as each individual stone numbered accordingly is shown.
Sequencing and Scheduling
On a larger project, sequencing is a very important factor in scheduling the fabrication of your project. This information is vital to making sure you get what you need in the order in which you need it. Typically, the sequencing should be received with the final approved shop drawings. As equally important, smaller projects over one semi load should also have a sequence submitted so as not to cause delay in fabrication and delivery of your project.
Upon receipt of the final stamped up approved drawings, we then generate shop tickets that will be released into the mill for fabrication. Delivery for your initial load will be within the time frame indicated on our proposal. Once delivery begins, we can confirm that it will progress throughout the duration of the setting and fixing period.

Our featured this month is the Univer-sity of Illinois at Springfield, IL. In an engineering feat coordinating a steel structure with stone, this monument at the University of Illinois in Spring-field shows how Indiana limestone can be used in even the most challenging of applications. Standard buff stone with a smooth finish creates a classic look on this modern work of art.
The mason on the project was Otto Baum Co., Inc. of Morton, IL and the Project Manager was Jedd Rocke.
