The purpose of this research was to develop a new system for overhead drilling into concrete so that the work can be done with less shoulder and arm force, reduced awkward shoulder and neck postures, and reduced exposure to dust. This project was intended to lead to the prevention of shoulder and neck injuries to carpenters

The researchers refined and field tested an Inverted Drill Press (IDP) – a device designed to enable construction workers to perform overhead drilling with less shoulder force, reduced awkward neck postures, less dust exposure and a lower risk of falling. The IDP allows the user to remain on the ground while drilling overhead into the ceiling, and does not require the drill to be held by hand. Based on focus group input, a camera system was added to the design so the user can see the drill and drilling site without extending the neck

Pilot and field testing results showed less fatigue (of the neck, shoulders, hands, forearms, lower back, and legs), greater comfort, and greater ease of use with the IDP device compared with the usual method of overhead drilling. Data from sensors worn by participants also revealed that the camera reduced awkward neck postures when drilling with the IDP. The IDP is generally slower than the usual method but in some circumstances can be faster

The final report identifies the types of situations in which it would be most beneficial to use the IDP device
