Subject: Retirement of Rick Sidwell


After 37 years with the company, our good friend and General Manager of Raisebor, Rick Sidwell, has decided to retire from day to day operations. Rick has spent his whole adult working life in the raiseboring business. Rick's knowledge and understanding of the raiseboring industry is unsurpassed.

On a personal note, we will miss the wisdom, professionalism, work ethic and dedication that Rick has shown the company over these many years. Although Rick is retiring from the day to day routine, we are pleased to announce that he will stay with the company as a much valued consultant. We also want to thank Rick's wife Donna for her support and understanding over these many years. She is a unique and special lady!





The most powerful raiseboring machine in the USRAISEBOR is the oldest and largest raiseboring contractor in the U.S. today, and is 100% American owned.

We appreciate the opportunity to introduce our raiseboring company and capabilities. The following web site pages will show you some of the past work our company has performed in contract raiseboring. You will note from these pages that they concern the use of:

  • Atlas Copco 123RH, the most powerful raiseboring machine in the United States, can pull a 20’ diameter raise at 3,000’ and larger diameters at shorter depths
  • Robbins 83RM raiseboring machine capable of 20’ diameter and 2,000’ deep
  • Ingersoll-Rand RBM7-SP-LH for 10-16’ diameter raises up to 800’ deep
  • Robbins 61R for 6’, 7’, and 8’ diameter raises
  • Robbins 41R for 3’, 4’, and 5’ diameter raises

For example, we have successfully completed projects which have included: 6’ diameter raises to a total depth of 2,250 feet; 9’ diameter to 1,800 feet; 12’diameter to 1,250 feet; 16.5’ diameter to 1,540 feet; 20’ diameter to 2,000 feet, just to mention a few. Our complete line of equipment ( including high pressure air compressors, generators, rig-up trucks, etc.) and our strong financial position which enables us to bond our work, give us the capability to perform complete turn-key surface or underground shafts, including steel- or concrete lining, without relying on assistance from our customers or other construction companies.

We would be very pleased to be added to your bidders list for any future projects that would encompass our raiseboring capabilities. We invite your inquiry and will provide cost estimates, as requested. If we can be of service, please give us a call at 505.334.8700.
