Magryn provides engineering designs for floating pontoons for a range of manufacturers. The pontoon pictured is a small private pontoon in West Lakes, Adelaide. 

These are not for boat mooring as there are no private motorboats allowed on West Lakes, but are for launching and retrieving rowing sculls, kayaks, and swimming platforms etc.

Retaining Walls on difficult sites

February 9, 2021

​Retaining walls are generally standard and quite easy to specify, however some sites may cause problems. These problems can include:

Retaining walls along or over easements.

Where an allowance must be made for excavation in the easement at a future date. This may mean a different type of wall other than a steel post/concrete sleeper wall (such as a gravity block wall that can be dismantled, if required), or longer than standard sleepers to span over the easement.

If your retaining wall is going to be built over an SA Water easement, it must not impede SA Water’s access to the easement, or have an impact upon any SA Water services.

Refer: Proposed Encroachment over SA Water Easements

Rock on site.

Retaining a rock wall may require a steel post/concrete sleeper wall bored and cast into the rock or a different type of wall.

As expensive as rock boring is, with the proper equipment this may be the best and cheapest option.

Alternatively, a steel-reinforced, concrete-filled blockwork wall on a  concrete slab footing may suit”.

Bamera Jetty Inspection

November 3, 2020
Filed under: Coastal Engineering — Tags: , — Peter Cornish @ 3:26 pm

Two of our engineers have recently undertaken an inspection (above and below water) of the Bamera jetty in Lake Bonney, for the Berri Barmera Council.

This is always challenging work, as River Murray water is very muddy, and the below water inspection needs to be done “by feel”.

Planning when relocating Buildings will save you money.

Filed under: Civil Engineering Companies Adelaide — Tags: — Magryn @ 3:01 pm

We get a lot of enquiries from members of the public who have purchased an existing shed or building from another person, and re-erected it on their property.

Council then becomes involved and ask them to seek development approval retrospectively for the works.

This retrospective work is difficult to undertake and costly, and also may involve remedial works on the structure to ensure that it complies with current standards and appropriate loads.

We always recommend that people looking to relocate existing buildings obtain council development approval prior to undertaking the works to avoid this retrospective work and costly surprises down the track.

If you are considering purchasing and relocating a shed or other buildings, contact Magryn first to avoid any unexpected costs or surprises from your local Council.
