Good morning, and welcome to our first quarter conference call. I'm pleased to report that we are off to a strong start in 2024. Before diving into our first quarter results, I would like to share an update on our organizational structure. During the quarter, we reorganized our operations to more closely align with our reportable segments, construction and materials. We believe that this new structure better positions our leadership team to manage the performance of these segments.
As a reminder, we previously organized into 3 operating groups, California, Mountain and Central. In the prior structure, our leaders managed both Construction and Materials operations within their respective groups. Our new structure results and our Construction experts overseeing Construction operations and our Materials experts overseeing Materials operations. Of course, our teams will continue to work together, but we believe the new structure will allow us to better leverage our expertise to drive top and bottom line growth.
Construction leadership is focused on supporting regions with growth strategies and project execution while leveraging resources across the company to better serve our national clients. For our Materials segment, newly centralized management functions, such as sales and quality control drive consistency and improved financial performance. Granite has invested significantly in the Materials segment over the last several years, with both acquisitions and strategic investments. And our Materials segment leadership will be tasked with identifying opportunities to build shareholder value for further organic investments and M&A.
Importantly, this new structure does not change our vertical integration strategy in our home markets. Regional leadership in both Construction and Materials segments will maintain the partnership that has differentiated Granite for decades. I believe this organizational change sets the foundation for Granite's next chapter and will accelerate our ability to provide shareholders with higher levels of return.
Moving to the Construction segment. I'm very pleased with the strong start to the year. Winter weather in the first quarter is typically our slowest, but our teams are off to an outstanding start in part because of more favorable weather conditions in 2024. So far in 2024, we have bid and won more work than in 2023, with CAP remaining flat from the fourth quarter, but increasing significantly year-over-year. While CAP was unchanged during the quarter, the market has been consistent with our expectations.
Our markets in the public and private sectors continue to be strong in California and across our geographies, we expect CAP to grow in 2024. Best Value projects continue to be a focus and represent $2.5 billion or 46% of our total CAP. The collaborative delivery methods captured in this number, like Construction to manage a general contractor or progressive design-build, better position us for success by allowing us to collaborate with our clients to mitigate risk.
Larger Best Value projects are often separated into smaller work packages that are reviewed through multiple project workshops. This provides more opportunities to assess and address risks the large bid build projects. In the last 15 years, we have completed or have under contract 87 Best Value projects. Generally, these projects are constructed more quickly and with fewer claims. In the first quarter, Construction revenue increased 18% year-over-year, led by RTEs California, Utah and the Midwest. This was primarily a result of the higher CAP entering the year and the more favorable weather conditions compared to the first quarter of 2023.
With our strong start to the year, our current CAP and the bidding opportunities ahead of us, we are on track to win the work needed to meet our revenue guidance in 2024 and continue our organic growth in 2025. Moving to the Materials segment. The first quarter benefited from price increases and higher volumes associated with more favorable weather in our most seasonally impacted quarter. As mentioned previously, we are focused on price increases, targeting a 10% increase on average in aggregates and 5% in asphalt.
So far this year, our price increases align with this expectation. We will continue to monitor progress as the year continues, we approach the heart of the construction season. Over the past 3 years, we have significantly invested in our Materials segment. We expect this pattern to continue in 2024 with approximately $50 million of planned strategic investments in further automation projects at plants, new reserve expansion and a new aggregate plant that is expected to come online later this year.
We ended 2023 with 1.3 billion tons of reserves, an increase of 294 million tons or 30% since 2021. This includes 140 million tons of reserves added through acquisitions in 2023. In 2024, we will continue to explore M&A options for both bolt-on opportunities and possible expansion into new geographies. We remain very selective in our pursuits, but I'm hopeful we will complete additional materials M&A transactions in 2024. Now I'll turn it over to Lisa to review our financial performance for the quarter.
