Site and Highway Staking with Trimble SCS900

Benefits of doing your own stakeout

Stakeout has historically been labor intensive– Multiple person crews

Using Trimble technology reduces labor– Allows single person crews for

GPS (SPSx81) Robotic Total Station (SPSx30)

Reduces cost– Reduces need for subcontracted layout

Reduces downtime– No need to schedule or wait for crews to arrive

Puts the power of data in your hands– Documentation of stake positions and accuracy

SCS900 Stakeout Menu

Option 3 – Stakeout Menu Different menu depending on design loaded– Surface design (TTM)– Road design (PRO)

Stakeout Settings

Staking Points

Stake to coordinates (NEZ)– Structures, utilities, radii,

corners

Picking Options– Pick from plan view– Pick from list– Create new

Staking Lines

Stake EP, curb, pads, lots, utilities, contours Picking Options– Pick from plan view– Create New

Other Options– Reverse– Station / offset– Tangent / corner points– Staking Interval

Staking Side Slopes & Catch Points

Project any line at any slope Dynamic daylight / catch points– Intersection updated using current ground

elevation– Useful when model doesn’t daylight correctly,

slopes are not complete, or slopes need to be modified

Staking Planes

Simple slopes or pads– Good for temporary work that is not in design

3 Types– Level Plane– Sloping Plane– Three Point Plane

Staking Surfaces

Live Cut / Fill to current design Good for supervisors or inexperienced users

Staking Roads – Option 1

Roadway Feature– Pavement

CL, EP, Curb, Shoulder

– Dirt SG, Ditches, Benches

Staking Roads – Option 2

Catch Point– Stake design tie slopes– Stake user defined slopes

Staking Roads – Option 3

Location on Surface– Cut / Fill on the road at

Specific Station / Offset Any random location

Report Utility

What data is recorded during stakeout?– Measured NEZ– Raw data (LLH or HA/VA/SD)– Precision – Design NEZ– Cut / Fill– Horizontal deviation from staked point– Station / Offset (lines or roads)– In / Out of tolerance– Rod height– Date and time
