Precision Surveying for the I-84 Highway Project in Utah
Utah’s I-84 highway construction project required precise surveying and engineering expertise to meet the Utah Department of Transportation (UDOT) standards. Anderson Engineering partnered with Gilbert Western Corp to provide critical support in surveying, volumetric analysis, and engineering layout services for 10 miles of interstate improvements. Our team leveraged advanced GPS technology and expert engineering support to deliver accurate results, ensuring regulatory compliance and efficient project execution.
The project scope involved concrete paving, shoulder embankments, interchange realignments, and bridge rehabilitation, all of which required high precision to avoid costly rework and delays. Anderson Engineering’s surveying capabilities provided real-time data and layout solutions, keeping the project on track while addressing the complex challenges of highway construction.
Challenges in Highway Surveying and Construction
The I-84 project presented several challenges that required specialized expertise and precise execution.
Key Challenges Faced:
- Accuracy in Surveying and Layout:
- Ensuring precise roadway alignment and structures prevents discrepancies that could lead to rework.
- Regulatory Compliance:
- Meeting UDOT’s stringent standards for surveying and reporting.
- Project Timelines:
- Coordinating construction efforts to align with the project’s tight deadlines.
- Resource Limitations:
- Augmenting Gilbert Western’s capabilities with experienced survey crews and engineering support.
Failure to address these challenges could have resulted in:
- Delayed project timelines, leading to financial penalties.
- Increased project costs due to rework.
- Potential safety risks due to inaccurate layouts.
