For decades, spreadsheets have been the default tool for managing data in construction materials testing (CMT) and geotechnical laboratories. From logging concrete compressive strength results to tracking soil samples and lab schedules, Excel has offered flexibility at a low upfront cost.
But the demands placed on modern labs have changed.
Today’s CMT labs are expected to process higher sample volumes, meet stricter ASTM and AASHTO requirements, support ISO 17025 accreditation, and deliver results faster to clients and agencies. Under these conditions, spreadsheets often become a liability rather than an asset.
As a result, many labs are replacing spreadsheets with a Laboratory Information Management System (LIMS) designed specifically for construction materials testing. This article explains why that shift is happening, where spreadsheets fall short, and when a LIMS becomes the smarter long-term choice.

Spreadsheets are familiar, but they were never designed to manage regulated, high-volume lab workflows. As labs scale, several structural problems emerge.
Manual data entry and spreadsheet formulas introduce unavoidable risk:
In regulated testing environments, even small errors can lead to failed audits, rejected reports, or rework.
Spreadsheets provide little to no built-in traceability. This makes it difficult to:
During audits, labs often scramble to piece together records from multiple files, emails, and folders.
When multiple people work from spreadsheets, problems multiply:
This is especially problematic for labs coordinating between field technicians, lab staff, and project managers.
Spreadsheets do not inherently enforce ASTM or AASHTO rules. This leads to:
Compliance becomes a manual policing effort rather than a built-in system control.
👉 These challenges are especially problematic for labs subject to frequent audits. Learn how modern systems address this in our article on ASTM and AASHTO compliance in a LIMS.
A modern LIMS is not just a digital replacement for Excel. It is a workflow system designed to manage samples, tests, compliance, and reporting end to end.
A LIMS designed for CMT labs includes:
This ensures consistency across technicians, projects, and locations.
Unlike spreadsheets, a LIMS tracks the entire lifecycle of a sample:
Every result is linked back to its origin, technician, and project context.
With a LIMS, compliance is embedded in daily operations:
This makes ISO 17025 audits and DOT inspections significantly easier to manage.
A centralized system allows:
Let’s look at a simplified example of potential savings:
| Task | Time w/ Spreadsheets | Time w/ LIMS | Weekly Savings |
|---|---|---|---|
| Data entry | 8 hrs | 3 hrs | 5 hrs |
| Report creation | 5 hrs | 1 hr | 4 hrs |
| Audit prep | 3 hrs | 0.5 hr | 2.5 hrs |
| Total | 16 hrs | 4.5 hrs | 11.5 hrs |
At an average technician rate of $35 per hour, that equates to more than $20,000 per year in recovered labor for a single lab team.
Spreadsheets may work temporarily for very small operations, but most labs reach a tipping point.
Clear signs it is time to move to a LIMS include:
At this stage, a LIMS is not a technology upgrade. It is an operational necessity.
Generic LIMS platforms often require heavy customization and still fall short. Purpose-built systems like Aldoa are designed around real CMT workflows.
👉 If you are actively evaluating vendors, see our guide to compare LIMS software for geotechnical labs.
Begin with a single test type or department. This reduces disruption and allows teams to build confidence before expanding.
Most labs do not need to migrate every spreadsheet. Focus on active projects and high-value historical data. A strong LIMS provider will support structured data imports.
The fastest ROI comes when technicians actually use the system correctly. Prioritize intuitive workflows and hands-on training.
Spreadsheets served their purpose, but modern construction materials testing demands more control, visibility, and reliability.
A purpose-built LIMS helps labs reduce errors, improve compliance, accelerate reporting, and scale without adding administrative burden. More importantly, it replaces fragile spreadsheet workflows with systems designed for regulated, high-volume testing environments.
If your lab is still managing critical test data in Excel, the real question is no longer if you should switch, but when.
