About Us

They call me the Pole Whisperer “I turn HUMUNGOUS MONSTER POLES into gentle giants”

We install all sized poles, lighting columns and foundations in the most efficient and economical way possible, OH&S compliant and with all installations conforming to the Australian Standards AS/NZS 4676:2000 Structural Design Requirements for Service Utility Poles.

Standard base plate mounted floodlighting column. The height is generally determined by the size of the area to be floodlit and the strength is proportional to the number of floodlights required at the head of the column to meet the illumination level over that area. Heights vary from 4metres (walkway lighting) to in excess of 60 metres (stadium lighting).

Base plate mounted mid-hinged see saw column. This column is hinged close to the centre of the overall height of the column and operates in the same manner as a child’s see saw. The pole has a hinged tail section which is perfectly counterbalanced to meet the weight at the head of the column and can be lowered and re-erected for maintenance purposes with considerable ease. If the load at the head of the column is increased beyond the design weight (the column will descend too quickly) or if decreased the column may be too difficult to lower.

The column can be rebalanced providing the load at the head of the column is not increased beyond the maximum rated design values of the column, the counterbalance weight can be increased or decreased to where the raise and lower function of the column is manageable once again. See Saw columns generally range from 8 metres to 30 metres

Camera and Communication Columns. These are specially designed columns for minimal deflection for security cameras and communication aerials.

High Mast Lighting Towers (HMLT). These are heavy duty base plate mounted lighting towers which have a head frame which supports multiple floods and is lowered to ground level for maintenance by means of a winch located inside the base of the column.

HMLT columns usually range from 25metres to 40 metres.

Power lift lighting columns. These columns are heavy duty floodlighting columns and are hinged a short distance from the base and are powered up and down by the means of hydraulic cylinders and a hydraulic power pack unit.

C & E A Scope have been established for 37 years during which time we have regularly installed all the above types of steel columns and poles which require similar but varying installation procedures.

Let our experience become part of your pole installation solution.

Assembling lighting columns

Columns longer than 6.5 – 10 metres are manufactured in sections for ease of transportation purposes, the number of sections being dependent upon the overall length of the column. The sections have a precise taper and the upper sections are a compression fit over the lower section and have a minimum slip joint (overlap) distance which is determined by the manufacturer.

The slip joint distance will vary according to the diameter and the strength of the column and will generally require a minimum of 5 tonne to meet the required sip joint distance. We have designed our own purpose built hydraulic unit with varying capacities of 8 tonne, 12 tonne, 16 tonne and 24 tonne to ensure that the manufacturers minimum slip joint is achieved at all times for all size columns.


All steel columns have an Ultimate Base Moment rating in Kilo Newton Metres kNm the capacity of which is provided by the manufacturer and foundations are designed on the Base Moment Capacity of the column to be installed. Foundations for base plate mounted columns have a steel reinforcing cage with a bolt set configuration to match the slots or holes in the base plate of the column, foundations can be either a slab foundation or a pier type.

The depth of the foundation is determined from the column Base Moment Capacity and the kPa rating of the subsoil conditions of the site where the column is to be installed. The depth is of critical importance and as a general rule of thumb the strength of a pier foundation is proportional to the depth cubed. If the depth of the foundation is doubled then the capacity will be 8 times and conversely if the depth is halved consequently the capacity is only 1/8th.

Manufacturers will normally supply a recommended footing giving the diameter and depth for average soil conditions of 100kPa and will also provide steel reinforcement and holding down bolt details. AS/NZS 4676 contains a formula for the calculation of the depth of a foundation based upon a single kPa rating throughout the depth of the foundation.

A geotechnical report will give the subsoil conditions at the depths required and in most cases will show several varying values in the kPa rating of the subsoil conditions throughout the full depth of the proposed foundation which will alter the design depth of the foundation.

C & E A Scope use the manufacturers recommended footing and adjust the foundation depth where a Geotechnical Report is available.

When a Geotechnical Report is unavailable we take readings with a pocket penetrometer throughout the excavation to ensure the kPa reading of the subsoil conditions is of adequate strength required for the Base Moment Capacity of the installed foundation.

All foundations are confirmed using a computer program which is based on the Brinch Hansen Method and has the capacity of inputting up to 5 layers of subsoil conditions of cohesive soils and also the ability to determine the foundation design using the angle of friction for non cohesive soils. A certificate of compliance to confirm the installation conforms to the manufacturers recommended footing and to AS/NZS 4676 will be issued with all installations including a copy of the Brinch Hansen computer generated output.
