INNOVATION AND VALUE ADDING

DANDENONG HOSPITAL Works to External Facade
AAU SJ Higgins provided forecast costs and scope of works to provide the
required outcome within a budget for the client. Domestic Imaging Offices
- SJ Higgins provided a plan and forecasted cost and scope of works to
provide the required outcome within a budget for the client.

Clashes with Existing Structure
SJ Higgins provided design advise to rearrange a 5 bed room which
looked to have lost a bed space due to clashes with an undocumented
concrete column in the middle of the room. The room was redesigned as
per SJ Higgins advise and the 5th bed was able to be achieved
MAROONDAH HOSPITAL ˃ Structural framing was value engineered during Stage 2 works to mitigate
costs and save time which impacted several trades across the stage.
˃ Floor preparation and screed works to meet the design intent were
value engineered substantially during Stage 2 Level 3 South, to mitigate
additional costs as a result of existing conditions.
˃ Floor vinyl specification was substituted by an equivalent product to
provide a cost saving.
˃ Numerous areas of the hospital’s existing facade were remediated during
the project as additional scope utilising existing access equipment at no
additional cost.
˃ A complete redesign of the lighting system was proposed to the design
team early in the project lifecycle and accepted by all stakeholders.
˃ Substituted Hydraulic fixtures for the dilapidated areas provided the client
savings on scope changes.
˃ Encapsulating asbestos sprayed concrete clips to provide a legislative
approved condition for minimal cost impact.

MASTERS STORE Structural design changes were utilised to improve buildability. Precast
MORNINGTON walls were upgraded to act as retaining walls and support suspended floor
slab.
Large 200CUM detention system under suspended floor slab was modified
to allow back filling to act as lost formwork.
ST MACARTAN’S PRIMARY Detailed material reviews found several costs savings including alternative
SCHOOL external cladding, alternative pergola framing timbers and alternative cavity
sliding door tracks, which achieved substantial cost savings.
LAKE VERMONT MINE There were a number of design and construction methods which allowed
SJ Higgins Group to reduce costs.
The Concrete slabs were designed to allow the Ultra Class Haul Trucks to
be jacked anywhere on the slabs and also allow tracked machinery to be
driven over the concrete. This was achieved by adding 50kg/m of steel
fibre reinforcing into the concrete to minimise damage done by tracked
machinery. This resulted in not requiring Steel rails to be installed in the
concrete slabs and then further reduced costs by working with our concrete
batching plant to produce the concrete and deliver it so that the steel
fibre was located only within the top half of the 425mm thick slabs. This
was achieved without the formation of cold joints by retarders and careful
programming. The structural steel design was also developed to ensure
internal bracing and welded beam members were not required. This was
completed by using large struts external of the building to support the large
building mass.
