Constancia puts safety on the “line”: 21 million hours and only one lost time accident in 2014
Building a large open pit mine is a complex undertaking that can require thousands of employees working “round-the-clock” shifts and using a vast array of heavy-duty construction vehicles and equipment, as well as explosives. With that understanding, Hudbay’s achievement in developing its Constancia mine in Peru is truly remarkable – during peak construction, the teams working on the Constancia project logged approximately 21 million hours with just one lost time accident (LTA).
With over 7,000 workers, including contractors, on-site at any given time, there were only 14 lost time accidents in 38.6 million hours worked throughout the entire construction phase. The strong safety performance continued as the site moved into production. Constancia recorded a 0.1 LTA frequency in 2014.
The exceptional performance of the Constancia team starts with Hudbay’s organization-wide commitment to safety. From the onset, safety was designated as the number one priority, and steps were taken to ensure that this commitment was reflected in action.
While the project management and safety teams played critical oversight roles, accountability for safety belonged with the line organizations. Ausenco, the engineering, procurement and construction management (EPCM) firm that Hudbay engaged for the project, led the charge. As the administrators of construction contracts and contractors, Ausenco’s engineering and construction management teams delivered Hudbay’s safety message to the project’s various contractors and from there to individual work teams and employees, both craft and unskilled labour.
During the project, Hudbay hired workers from nearby communities, many of whom had never worked in a construction environment. Special communication materials about safety were developed for this group. Along with daily briefings and other more informal channels, these communications helped local workers develop a positive and proactive approach to safety-related issues. Later in the project, one of the tools Ausenco employed was the Positive Attitude Safety System (PASS). Already used at Hudbay’s mines and projects in Manitoba, PASS is based on facilitated discussions at every level of an organization to increase individual involvement in recognizing and managing workplace risks.
Hudbay built a culture at Constancia where safety is a core value, and this was the key to 21 million hours with only one LTA in 2014.
