What is the Proctor Value? Sharing Lab Data in Real-Time

Laboratory results are like wisdom and knowledge; they are only good when shared with the right people. In any construction project, material testing and inspection plays a key role for final acceptance by stakeholders and users. Construction inspection and material testing firms continuously perform tests on a wide range of materials for compliance with the project specifications.

However, in order to determine compliance, the project specifications need to be available. Providing results in a timely manner is critical for the success of the project. Omnant provides the tools to disseminate results and information to the project team.

The Two Sides of Construction Testing

The construction inspection and testing portion of any project has two major components: the fieldwork and the laboratory work. The fieldwork is the one we commonly see. A technician or inspector: on-site with a nuclear density gauge during earthwork, casting concrete cylinders for compressive strength testing, with a Dynamic Cone Penetrometer (DCP) checking bearing capacity, measuring elongation of the tendons in a post-tensioned elevated concrete slab, etc. All of this construction materials testing equipment requires proper calibration and coordination with laboratory results. The fieldwork or "the fun side" is the visible side of the testing and inspection work.

The laboratory work is the "behind the scenes" part of the testing and inspection that very few get to see. The fieldwork depends on the laboratory work as much as the laboratory work depends on the fieldwork. The laboratory is responsible for preparing the equipment to be used by the field personnel, ensuring everything is calibrated, charged, verified and ready to use. The laboratory is also responsible for performing proctor tests and other critical analyses to provide accurate and trustworthy information to the field personnel as well as the clients.

Proctor testing, specifically, determines the optimal moisture content and maximum dry density of soil samples. This fundamental soil compaction test provides the baseline measurements that field crews use to verify proper compaction in the field. Following AASHTO testing procedures, these tests establish the critical proctor values that determine project compliance. Without accurate proctor values, field personnel would be working blind, unable to determine whether earthwork meets the project specifications. A single incorrect proctor value can lead to failed inspections, project delays, and costly rework.

The laboratory and the field maintain a symbiotic relationship that supports the project's success.

Managing Proctor Values Across Multiple Projects

While field personnel focus on a few projects every day, the laboratory focuses on all the projects every day. This could create a mountain of work that, if not properly organized, can become a massive headache for everyone. A robust laboratory information management system becomes essential for managing this complexity. More importantly, the laboratory needs to efficiently and reliably provide the results of testing, including critical proctor values, to the field personnel so they can test and inspect the materials in the field.

Bridging Laboratory & Field Operations

Omnant has become the preferred bridge to link the laboratory with the field. We provide the field personnel the access to laboratory results as instant as they are approved by the laboratory. Our platform organizes and eases the process of distributing results and reports to the project team.

Real-Time Access to Proctor Values in the Field

As part of Omnant, field technicians have access to drawings, specifications and notes for each project through powerful field inspection software. Additionally, Omnant provides the functionality of assigning the concrete mixes and proctor values for every project. This allows the field personnel to verify the concrete mix specifications and proctor values in the palm of their hand while in the field. Furthermore, as the field technician enters the results of the concrete testing, Omnant automatically compares the project specifications and instantly notifies the user if something is not in compliance.

Consider a hypothetical scenario: a field technician performs a nuclear density test on a compacted soil lift and gets a density reading. Without immediate access to the corresponding proctor value, they cannot determine if this meets the required compaction percentage. With Omnant, that same technician can instantly pull up the proctor value, perform the calculation, and know immediately whether the lift passes or needs additional compaction.

24/7 Access to Critical Testing Data

All approved reports are available 24/7 from anywhere on planet Earth. As long as you have internet access, you can see all the field, laboratory and compressive strength reports as well as requesting inspections. Modern construction field reporting has revolutionized how teams access and share critical data. This feature allows the inspectors as well and the project superintendents to review previous reports and build a path forward together. This also allows supplemental inspectors to pick up the tasks exactly where they were left. As for the accounting personnel, with Omnant, there is no more waiting on a call back or an email for reports, just log in and download it.

The importance of having historical proctor values available cannot be overstated. Soil conditions can vary significantly across a project site, and different areas may require different proctor values based on the specific soil types encountered. When a new inspector joins a project mid-stream, they need immediate access to all previously established proctor values to maintain consistency in testing protocols. This continuity prevents confusion and ensures that all team members involved in construction materials testing are working from the same baseline data.

Omnant's ability to consistently and reliably share the laboratory and field data, including proctor values, in real-time has been vital to the success of many projects.
