Temporary Works Engineering in Auckland CBD
Temporary works are at their most demanding in the central city, where deep basements, tight boundaries and live neighbours leave no margin for error. Temporary works are the props, shoring, falsework and excavation support that hold a site safe while the permanent structure is built, removed or modified, and on a constrained CBD site they often drive the whole construction sequence. LDE combines structural and geotechnical engineering to design the temporary stages of construction, demolition and dismantling across central Auckland.
We design basement retention and excavation support, propping and shoring for alterations and facade retention, and falsework and formwork for suspended structures on papa siltstone and reclaimed waterfront ground. We also set out craneage and lifting support and check stability and load paths during construction, coordinating closely with the contractor and the permanent design. Working under the Auckland Unitary Plan, we keep complex city projects moving.
For Auckland clients, that means temporary works engineering built for constrained, high-stakes sites.
How our Auckland CBD team delivers temporary works
Central-city sites rarely give you room to move, so retention, excavation support and propping drive the temporary works and often the whole build programme. Our Auckland engineers design basement retention and excavation support in papa siltstone and reclaimed ground, plus the propping, shoring and facade retention that alterations and partial demolition need on tight sites. Throughout, we check the load paths and stability so the part-built structure stays safe alongside its neighbours.
It is the same temporary works engineering we bring to building and transport projects across the city, combining structural and geotechnical input so the temporary stages suit both the structure and the ground.
- Basement retention and deep excavation support on constrained sites
- Propping, shoring and facade retention for alterations and partial demolition
- Falsework and formwork design for suspended slabs and structures
- Craneage, lifting support and stability checks during construction
Temporary works safety and standards in Auckland
Temporary works carry significant risk in a dense city, so design, independent checking and a controlled load sequence are essential, particularly where excavation and retention sit next to live buildings and services. We work to WorkSafe New Zealand guidance on excavation and construction safety and to recognised national standards, with consents under the Auckland Unitary Plan administered by Auckland Council.
- WorkSafe New Zealand excavation and construction safety guidance
- Standards New Zealand loadings and temporary structures standards
- Temporary works design, independent checking and monitoring of adjacent structures
LDE temporary works in central Auckland
LDE supports construction across central Auckland with temporary works engineering for buildings, alterations, facade retention and infrastructure, from basement retention and excavation support to propping and falsework on constrained city and waterfront sites. The central city keeps building upward and the harbour edge keeps being renewed, and the temporary stages of that work need the same structural and geotechnical rigour as the permanent design. You can see the breadth of our regional delivery on the projects page and across our building work.
Common questions about temporary works in central Auckland
What temporary works does a CBD project usually need?
Most central-city projects need basement retention and excavation support, propping and shoring for any alteration or partial demolition, and falsework for suspended structures, all sequenced around live services and neighbouring buildings. The temporary works often set the construction programme on a tight site.
How do you protect neighbours during a CBD excavation?
We design retention that limits ground movement, set out the excavation and support sequence carefully, and specify monitoring of adjacent structures and services. On constrained central sites this is central to the temporary works design, and we coordinate closely with the contractor to keep deflection and settlement within safe limits.
What is facade retention and when is it needed?
Facade retention is a temporary structure that holds a heritage or street frontage in place while the building behind it is demolished and rebuilt. It is common in the central city, and we design the retention frame and its load paths so the facade stays safe and stable throughout the works.
