Which type of stake is used to prevent the loss of reference information during construction?

Offset stakes are utilized to establish a reference point that remains visible and accessible throughout construction activities. These stakes are placed at a predetermined distance away from the actual construction line or feature, providing a safe and clear reference that can help maintain alignment and grade without being disturbed by ongoing work.

During the construction process, especially in earthworks and site grading, it is crucial to have stable reference points that won’t be removed or compromised as work progresses. Offset stakes achieve this by allowing surveyors and contractors to measure back from the stake to the desired construction line or grade, thereby preventing any potential confusion or errors due to changes in the site.

Other types of stakes, while important for different applications, do not serve the primary purpose of maintaining reference information as effectively as offset stakes. For instance, finish grade stakes indicate the final grade level but may be removed or altered as the project reaches completion. Slope stakes help establish the appropriate angle for slopes, and shoulder stakes define the edge of roadways, yet these can be less reliable for maintaining long-term reference compared to the stable positioning of offset stakes.
