The problem
A Delayed As-Built Delays Your Payment. A Rejected One Delays It Twice.
As-built surveys are the last step before the GC signs off. When the survey is late, the submittal is late and the payment is late. When the survey doesn't match the GC's format or tolerance requirements, the submittal gets kicked back and the clock resets.
Most earthwork contractors treat as-built surveys as an afterthought because they come at the end of the job. But the end of the job is exactly when cash flow pressure is highest and the least time is available to fix a documentation problem.
Getting the as-built done right and fast is how you protect your payment and your relationship with the GC for the next job.

As-Built Surveys That Match the Spec and Come Back Fast
We collect GPS as-built data on your finished site, process it against your design surfaces and produce a formatted survey package that matches your GC's submittal requirements. We confirm the format requirements before fieldwork begins, not after the report is drafted.
Most as-built packages are delivered within 48 hours of field data collection. If your closeout timeline is tighter than that, tell us and we'll tell you what's possible.
What's Included
What You Receive with Every As-Built Survey
GPS Field Data Collection
Our field crews collect GPS point data across your finished surfaces at density appropriate to your project spec. Elevations, horizontal positions and feature locations are captured to the accuracy required by your GC or engineer of record.
As-Built versus Design Comparison
We overlay your collected as-built data against your original design surfaces and produce a deviation report. Color-coded deviation mapping shows where finished grades match design and where they fall outside tolerance. You see the comparison before your GC does.
Formatted Survey Report
Your as-built report is formatted to your GC's submittal requirements, not a generic template. Section headers, data tables, drawing references and certification language are matched to the spec before the report is generated.
As-Built Drawing Preparation
Where required, we produce as-built drawing markups showing the finished condition of grades, structures or utilities against the design drawing set. Formatted for digital or print submittal.
Pre-Submittal Deviation Review
Before your report goes to the GC, we review the deviation comparison with you. If anything is outside tolerance, you know before the submittal goes in and you have the option to correct it first.
48-Hour Turnaround Target
Most as-built packages are complete within 48 hours of field data collection. We track this internally because your payment timeline depends on it. If a project cannot meet the 48-hour target due to size or complexity, we tell you at the quoting stage.
As-Built Documentation for Common Earthwork Project Types
Mass Grading and Commercial Pad Sites
Finished grade verification across large earthwork areas. Pad elevation certification, subgrade compliance and deviation reporting formatted to civil engineer or GC requirements. Common for industrial, retail and warehouse developments.
Road and Drainage Projects
Horizontal and vertical as-built documentation for road grading, curb and gutter, drainage channels and utility corridors. Formatted to TxDOT or private GC specs depending on project funding and oversight.
Foundation and Slab Work
Finished slab elevation surveys and foundation as-built documentation for structural engineer review. Confirms that the finished foundation matches the structural design before framing or steel erection begins.
Utility and Underground Infrastructure
As-built location and depth documentation for underground utilities placed during earthwork. Formatted for utility record keeping and GC closeout packages.
Process
How an As-Built Survey Project Works
Step 1
Share Your Closeout Requirements
Send us your GC's as-built spec, your original design files and your closeout deadline. If your GC has a standard as-built submittal format, include it. The format confirmation happens before fieldwork, not after.
Step 2
We Confirm Scope and Schedule
We review your requirements, confirm the field data collection scope and schedule your crew. We provide a quote and a confirmed delivery timeline based on your closeout deadline. Most quotes are returned within one business day.
Step 3
We Collect As-Built Data On Site
Our field crew collects GPS as-built data on your finished site. Point density matches your spec requirements. Data is collected to the same datum as your design files for an accurate comparison.
Step 4
We Process, Review and Deliver
We process the field data, run the deviation comparison and produce your formatted report. We review deviation results with you before submitting. Your package is delivered within 48 hours of fieldwork completion in most cases.

Frequently Asked Questions About As-Built Surveys
What's the difference between an as-built survey and a QA/QC package?
An as-built survey documents what was built: horizontal positions, elevations and feature locations on the finished site. A QA/QC package uses as-built data as its foundation and adds construction quality records, deviation analysis and compliance documentation required for formal project closeout. We offer both, individually and combined.
How quickly can you turn around an as-built survey?
Most as-built packages are delivered within 48 hours of field data collection. We track turnaround internally because your payment timeline depends on it. If a project can't meet the 48-hour target due to size or complexity, we tell you at the quoting stage so your closeout schedule is never a surprise.
What format do you deliver the as-built report in?
We format your as-built report to your GC's submittal requirements rather than a generic template. Section headers, data tables, drawing references and certification language are matched to the spec before the report is generated, and we can deliver formatted for digital or print submittal.
What if the as-built data shows out-of-tolerance grades?
You find out before your GC does. We review the deviation comparison with you before anything is submitted, so if a finished grade falls outside tolerance you have the option to correct it first rather than having the submittal kicked back.
Can you collect as-built data outside your listed service areas?
Yes. Our remote processing services go wherever a file can travel, and our field crews cover the major earthwork corridors across Texas including Houston, Dallas-Fort Worth, the Rio Grande Valley and Corpus Christi. Tell us where the project is and we'll confirm field availability.
Do I need to provide my original design files?
Whenever possible, yes. We compare your collected as-built data against your original design surfaces, so your design files let us produce the deviation report and comparison. Send them with your closeout requirements up front and we'll confirm format and datum before fieldwork begins.
Get Your As-Built Done Before Your Closeout Deadline
Tell us your project type, your GC's submittal requirements and your closeout date. We'll schedule the field crew, confirm the turnaround and get your as-built package delivered on time.
