GSR Annual Report 2024 Planet Pillar

We launched our Waste Management Dashboard to better track and understand our progress toward a Zero Waste culture. The dashboard gives our teams clearer insight into where we’re making an impact and where we can do more.

In 2024, one specific case study piloted three different temporary hybrid generator set-ups on the MAZ Data Center construction project in Mesa, Arizona.

The pilot, aimed at enhancing construction energy efficiency, air quality, and operational resilience on-site, compared two integrated hybrid generators from different manufacturers and an Energy Storage System paired with a separately procured diesel generator.

Designed as cleaner, more efficient alternatives to standard diesel generators, these hybrid setups were strategically implemented to power guard shacks and restroom trailers used by craft workers, ensuring reliable energy delivery while significantly reducing environmental impact. We work to procure renewable diesel fuel alternatives to further drive down emissions and increase air quality at the source.

Of the solutions piloted, the most favorable solution was the ANA Energy BossTM 25 kVA hybrid generator. It is a single trailer set up, significantly lighter than a standard diesel generator of the same capacity, has the ability for remote monitoring and maintenance, and utilizes a unique Lithium Titanate Oxide (LTO) battery technology that allows for very fast charging. This solution showed both the greatest cost savings and carbon reduction.

In 2024, we rolled out Phase 1 of our Ford F-150 Lightning pilot, deploying numerous trucks company-wide as part of our Path to Regeneration roadmap. This initiative aims to reduce emissions, lower operational costs, and integrate sustainable fleet solutions.

Feedback from drivers highlighted several key benefits, including lower fuel costs compared to traditional gasoline-powered trucks, reduced maintenance needs due to fewer mechanical components, and greater performance for daily commutes and jobsite visits. Some drivers also benefited from utilizing high-occupancy vehicles (HOV) or carpool lanes to reduce their overall commute time.

However, range limitations and charging accessibility posed challenges, particularly for those traveling to multiple jobsites daily. Drivers expressed interest in extended-range batteries, increased access to charging stations, and a more streamlined reimbursement process for off-site charging.

As we continue to scale our electric fleet, the Phase 2 improvements will ensure a smoother transition to zero-emission vehicles while maintaining the reliability and efficiency our teams need. DPR remains committed to driving sustainable innovation in our operations, making electrification a practical and impactful step toward a lower-carbon future.

Over the past year, DPR has focused on obtaining WELL certification for several of its offices and has been actively improving the jobsite environment for our field teams.

The DPR Office and Jobsite Sustainability Best Practices provide strategies for ensuring optimal building performance through design opportunities to maintain team health. Additionally, we have implemented programs to manage air quality and select materials wisely.

Whether at jobsites or in our offices, our people's health, safety, and well-being remain a top priority. IWBI recognized our commitment by awarding us the 2024 Health and Safety Leadership Award and the Rising Star WELL at Scale Award. We are committed to offering solutions and benefits that create a positive impact.

Through our concrete work, we are committed to reducing carbon emissions in the construction industry. Our concrete experts implement various methods to minimize the environmental impact of structures. These methods include using alternative materials to replace some of the cement, exploring different types of cement, improving aggregate mixing, and capturing CO2.

As a contractor that manages its own projects, we incorporate carbon tracking and reduction throughout the construction process. Recognizing that concrete significantly contributes to greenhouse gas emissions, this approach enables us to make critical decisions early on, establish standards, and promote lower-carbon options while also exploring various designs and measuring carbon usage.

We’re helping the industry take meaningful steps toward a more sustainable future through leadership, collaboration, and knowledge-sharing.

As a founding member of the Contractors Commitment, DPR is working to align best practices across the industry, ensuring sustainability becomes the norm rather than the exception. We also played a large role in developing the AGC Decarbonization Playbook, a first-of-its-kind resource that gives contractors the tools they need to track carbon emissions, reduce their environmental impact, and enforce more efficient jobsite operations.

But our impact doesn’t stop there. We were the first contractor to champion the Mindful Materials Forum, leading the charge in material transparency and driving widespread adoption of the Material Framework. Our partnership with NREL (National Renewable Energy Laboratory) also pushes the boundaries of sustainability, supporting groundbreaking research on energy-efficient construction.

Beyond our projects, we’re committed to educating and collaborating with the broader industry by participating in industry events.
