SAFETY
At Aldridge, safety isn’t just a priority; it’s a core value that defines our culture. We believe in a comprehensive approach to safety that encompasses not only physical well-being but also mental health and overall wellness. While we refuse to accept injuries as an inevitable aspect of the job, we acknowledge that incidents can happen. Therefore, we’ve established layers of protection and tools to minimize their impact. Our commitment to safety transcends industry standards; it’s exemplified by our Incident and Injury Free (IIF) culture. This cornerstone propels us towards safety excellence, striving for nothing less than being recognized as a worldclass organization. Our ultimate objective is clear: to foster an organization free from incidents and injuries, where every employee feels secure, supported, and valued. Our dedication to the IIF initiative doesn’t stop at the workplace; it also guides us in making safe decisions outside of work.
Craft Voice in Safety (CVIS)
Craft Voice in Safety (CVIS) creates a culture where everyone has a voice. Craft are taking care of craft, in partnership with management, through ownership, communication, and prevention, while fostering a culture of Incident and Injury Free to achieve our goal of Nobody Gets Hurt.
The Craft Voice in Safety (CVIS) program focuses on enhancing safety practices through active engagement and communication among craft workers and management. CVIS members play a crucial role in fostering a unified, safe, and productive work environment by serving as liaisons between their peers and project leadership. They are expected to:
• Promote Safety
• Address Safety Issues
• Develop and Review Policies
• Lead by Example
• Organize and Communicate
• Maintain Confidentiality
Making Safe Decisions®
Culture, leadership, systems, and processes play pivotal roles in determining the level of exposure control in the workplace. However, even with robust support in these areas, human error remains a possibility due to our innate fallibility. Our Making Safe Decisions® Approach enhances human performance reliability by deepening employees’ understanding of how the brain influences the recognition of SHOK exposure. It equips them with tools and techniques to mitigate brain-centered vulnerabilities, which we refer to as Brain Centered Hazards™, including Fast Brain Functioning, Visual Recognition, Divided Attention, Memory, Social Thinking, Fatigue, and Stress and Urgency.
Figure 2: Our 5 Making Safe Decisions Modules teach us how to reduce the internal brain centered hazards (exposures) so we are safe at work and at home one decision at a time.
Serious Injuries and Fatalities (SIF) Program
Before beginning work, our crews are trained to identify SHOK (Seriously Hurt of Killed) scenarios on their job sites. SHOK events occur due to the release or transfer of energy that cannot be absorbed safely. In the presence of highenergy exposures, it is imperative we build the ability to fail safely. The ‘STOP THE SHOK’ Program demands that we honestly assess the realities of serious injury exposures on our job sites, ensuring that successes are not left to chance and that failures do not result in fatalities. Our single and overarching objective is clear: to prevent events that jeopardize lives by averting life-threatening, life-altering, and life ending events.
Figure 3: The SHOK Exposure Wheel is a visual aid highlighting the eight high-energy SHOK exposures our employees encounter daily. It serves as a reminder to identify and control SHOK hazards throughout all work stages, aiming to prevent exposure and ensure safety even in the event of failure.
PROJECT DELIVERY
Aldridge employs a holistic project delivery approach, focusing on enhancing efficiency, productivity, and safety. Our services begin in the pre-construction phase, integrating PreFab, VDC, specialty tooling, equipment technology, and custom retrofits. By assembling the project team before construction starts, we ensure skillful execution and improved resource management throughout the project life cycle.

PROJECT PROFILES
Alta Farms ll Interconnect and Substation
Clinton, Illinois
Aldridge was selected for the installation of a new interconnect switchyard (POI, TSS 909 Deer Creek) and collection substation (HV, TSS 972 Alta Farms). The two substations, while on the same site, were designed to different specifications as they have different end users. The HV yard will be owned by Enel while ComEd will be the owner of the POI yard. One unique aspect is that the interconnect is a 3 breaker switchyard, which consists of three 345kV circuit breakers.
Crews performed all civil foundations, underground electrical work, steel erection and equipment setting.
