Verify Drawings

When BDI files are created, drawing errors are brought to light. Discrepancies between architectural and structural drawings are resolved up front before construction starts. Eliminating field down-time due to drawing errors.

Certify bridge components

Bridge components can be certified real-time.  The AutoGrade SPS gives the contractor the ability to layout points where and when they want it, thus eliminating the need for using string-lines and plumb-bobs. Forms can also be verified real-time. There is no longer the need to wait for surveyors for verification. Contractors can check their work anytime at no additional cost.

Set grades

Load the appropriate BDI file into the AutoGrade SPS. Choose your AGF file for storing shots and take random shots (F2) anywhere on the site.  the AutoGrade SPS will report real-time Cut/fill elevations.  The AutoGrade SPS will interact with an alignment to provide real-time station offsets of every  the AutoGrade SPS shot. These can be easily compared with the engineers templates.

Locate break-lines

After you have taken your grade shot press the Autoline button (F4).  The AutoGrade SPS will direct you to the intersection of construction lines. The direction will be an in or out from the sight line, and a left or right from the sight line. The sight line is from the total station setup point to the prism shot location.

Locate break-points

After you have taken your grade shot, press the Autopoint button (F5).  The AutoGrade SPS will direct you to the nearest construction point. The direction will be an in/out from the sight line as well as left/right. The direct distance to the construction point will also be displayed.

Example: out 12.5 right 5.0 direct 13.47

Set Scaffolding

The AutoGrade SPS knows the screed elevation of every square inch of the bridge deck. This gives the contractor an ability to set each individual scaffolding leg to the proper grade regardless of the scaffolding leg position. This saves time and increases accuracy. This saves on concrete quantities and ensuring proper deck thickness.

Reduce layout costs

Not as many surveyor points (stakes) are needed because all drawing information can be loaded into the AutoGrade SPS, eliminating the need for re-staking. As-built surveys are recorded in real-time.

Reduce downtime

The AutoGrade SPS provides more accurate information to build with, increasing construction efficiency and reducing the onsite repairs.  Minimizing the dependency of onsite surveying because you get your point where and when you want it in real-time, in turn eliminating downtime waiting for re-staking or as-builds.   This eliminates over building or under building along with the need for using string-lines and plumb-bobs. It also reduces equipment downtime by clocking less running hours on equipment.

* (Hand Held Data collector with   the AutoGrade SPS software)


How Does It Work?

1. Construction drawings are made digital.
2. Drawings are loaded into a hand held data collector.
3. The total station is setup anywhere on the site.
4. Sight any two control points and  the AutoGrade SPS will resection its location.
5. Place the prism pole anywhere. Push (F2) and  the AutoGrade SPS gives a real-time cut/fill.
6. Push (F3) and  the AutoGrade SPS saves the shot.
7. Push (F4) and  the AutoGrade SPS directs you to feature lines.
8. Push (F5) and  the AutoGrade SPS directs you to feature points.
