AUGUSTINE HEIGHTS STATE SCHOOL

vTCE was engaged to provide civil engineering detailed design of the Augustine Heights State School, which will accommodate approximately 1100 students at peak intake. The school includes prep, junior and senior learning precincts as well as administration, covered play areas, amenities and sporting facilities.

Many challenges needed to be overcome to provide a cost effective and code compliant design to achieve a satisfactory outcome for all stakeholders. The site comprises an irregular shaped, steeply sloping topography, an existing waterway through the lower eastern portion of the site, existing creek to the south and a future rail corridor to the north. As a result, the surrounding ecology sensitivities were factored into the design for the area.

VTCE completed civil engineering of the internal and external scope, including bulk earthworks, stormwater pit and pipe networks and quality/quantity modelling, 700m of council collector road design, modified pavements, signage and line marking, waterway relocation (fish passage realignment), flood impact co-ordination, water reticulation main, sewer low pressure system and gravity sewer main designs.

Regular consultation with the authorities was required to help expedite all necessary approvals:

Dept of Transport and Main Roads (DTMR) provided advice regarding the future rail corridor levels to assist with the vertical geometry of the council road upgrade.
Dept of Agriculture and Fisheries (DAF) advised on the waterway relocation.
Ipswich City Council (ICC) provided guidance on the road class and acceptable cross section.
Urban Utilities (UU) required preliminary planning to be done for a future trunk sewer main to ensure serviceability of the school and surrounding areas via gravity main.
SEQWater owns and operates a 1050dia MSCL water main along the road corridor which required close consultation to ensure appropriate cover and clearances to all new infrastructure remained intact, or protective measures installed.

For cost-saving, site considerations and utility constraints for this project, vTCE documented geogrid and geotextiles as part of a modified pavement design. This was done to counteract the low strength and highly reactive nature of the soils encountered on site.

Close site supervision allowed for all design elements to be properly incorporated into the site work and ensure smooth running of the construction process.
