Bothwell Logo


This is a very easy system to build with. I’ve not had any complaints from my in house or traveling scaffold techs who as a whole are resistant to change and a pessimistic group. I sat them down and we watched Tim’s video and then I had a Q&A session with the guys on how the decking system worked. We transitioned from wood to Bothwell at Oconee. In our transition phase we removed the wood from the scaffold frames that had to stay up for plant maintenance and put the Bothwell boards back in place. This was patch work as the scaffold frames were not constructed in a manner (widths and lengths nor square) to ideally work with the Bothwell system. However, the transition went very smoothly. Once we started building new scaffold frames knowing we would be using Bothwell we really started seeing the time savings. I would say we decreased our build times by 1/3 on average and our removals by about the same. We were able to do this because we weren’t pulling nails out of plywood, we were not having to cut a bunch of #9 wire to secure the boards on the scaffold bearers, we weren’t having to sweep up saw dust, we weren’t having to hunt pieces of diamond plate that would work to fill in gaps in the deck caused by plant equipment coming thru the deck, etc... We used all Bothwell in our last outage in the containment building and saw significant dose savings for the reasons I mentioned above. In fact the site had the lowest accumulated dose ever for Unit three at Oconee. To see the gains we’ve seen at Oconee you MUST buy the boards starting at 6” and going to 7’ in length with hook ends on all of the boards and both widths 6” and 9”. You will also need the float bars. I guarantee you if you buy all of the pieces you will not find a scenario where the Bothwell system will not only work but it will be quicker to install and the appearance will be superior to any other product you can find. If you make the mistake my counterparts at the two other Duke sites did and buy odds and ends and don’t get the hook ends you will frustrate your builders and you will not see optimum gains. I’ve found we rarely ever use diamond plate (which the system is engineered to accommodate with the tack strips) due to the versatility created by the float bars. Therefore, we seldom have the need to use screws and diamond plate to fill gaps in our scaffold decks.
