Levelling Staff
Levelling staffs are graduated measuring staffs used with surveying and levelling instruments to determine height differences and transfer levels across a site. They are commonly used in construction, civil engineering, groundworks, drainage, roadworks and other surveying applications where elevations need to be checked or recorded.
Celtic Surveys supplies levelling staffs in different materials and configurations, including telescopic aluminium and fibreglass options. The right staff depends on the levelling instrument being used, the required working height and the type of site work involved.
Levelling Staffs for Surveying and Site Work
A levelling staff provides the graduated scale used when taking readings with a surveying level. The staff is positioned vertically at the point being measured, allowing the operator to compare readings between different locations.
Levelling staffs are commonly used with Automatic Levels for tasks such as transferring elevations, checking excavation depths, setting foundation levels and monitoring changes in ground height.
They can also be used as part of compatible laser-level setups where a receiver is mounted to the staff.
Aluminium and Fibreglass Levelling Staffs
Levelling staffs are available in different materials to suit different working conditions.
Aluminium levelling staffs provide a lightweight and practical option for general surveying and construction work. Telescopic sections allow the staff to extend for measurement and collapse to a shorter length for transport and storage.
Fibreglass levelling staffs provide an alternative where a different material or construction is preferred. As with aluminium models, the number of sections, maximum length, graduations and supplied accessories can vary between products.
For either type, clear graduations and secure section locks are important for straightforward use on site.
Choosing a Levelling Staff
When selecting a levelling staff, consider the instrument it will be used with and the type of work being carried out.
Important points include:
- Maximum staff length
- Collapsed length
- Number of telescopic sections
- Graduation style
- Aluminium or fibreglass construction
- Staff weight
- Section-locking system
- Compatibility with receiver brackets where required
- Carrying and storage requirements
A 5m staff is a common option for general surveying and construction work, but the required length depends on the site and measurement range.
If the staff will be used with a laser receiver, check that the receiver bracket can be fitted securely to the selected staff.
Using a Levelling Staff on Site
For a reliable reading, the staff should be positioned vertically and placed firmly on the point being measured.
A staff bubble can help with vertical positioning, while stable ground and securely extended sections help keep the staff steady during the observation.
Levelling staffs are used across a wide range of site work, including foundations, floor levels, drainage, road construction, landscaping, excavation and general groundworks.
They are also useful where repeated readings need to be taken from identified survey points as work progresses.
Surveying Accessories for Levelling Work
Levelling staffs are normally used as part of a wider surveying setup rather than on their own. Depending on the work, this may include an automatic or digital level, tripod, staff bubble, receiver bracket or other site accessories.
