Yarwun 2 Wharf Expansion - Survey Project

A US$1.8 billion expansion of the Yarwun Alumina Refinery, Gladstone by Rio Tinto. This was the $2b second stage of the former Comalco Alumina Refinery. The project included extension of the existing refinery site, expansion of the wharf facility & upgrade of the facility at the Residential Management Area. Site development, concrete, civil infrastructure & wharf construction was awarded to Golding Pty Ltd.

Ryan Surveys provided survey for the wharf construction which included control, pile driving, steel erection, precast concrete placement, embedment installation, concrete levels, rail & conveyor alignment, 3 dimensional (3d) modeling & all construction reports. Ryan Surveys identified large twists in the steel provided (up to 75 mm), which created complications with meeting site tolerances. Ryan Surveys surveyed all steel before installation, provided 3d models of the steel & solutions to the contractor to help with efficient installation, adhering to construction deadlines & recording time lost due to steel manufacturing errors.

Lake Lindsay Alliance German Creek Coal Mine, OLC - Survey Project

Thiess Sedgman Joint Venture in alliance with Anglo Coal Australia to expand German Creek Mine to increase its output capacity through the construction and commissioning of new coal handling facilities, including an overland conveyor.

Ryan Surveys was contracted to operate as swing shift surveyor and service the mechanical installation of the 26km long conveyer. Major responsibilities include monitoring the horizontal and vertical alignment of the installation, establishing and monitoring secondary control and providing “as constructed” reports.

G3 Alcan - Survey Project

G3 encompassed the 2.3 billion dollar expansion project of the then Alcan bauxite refinery in Nhulunbuy (Gove). Ryan Surveys was employed as project surveyor under Cross Surveys and Development.

Many elements of the G3 project had never been attempted on such a scale. The project required the jig sawing of a number of pre assembled modules (PAMs) and Super PAMs (shown) constructed in yards off-site (five in Asia and two in Australia). Once constructed, PAMs were shipped to the Gove Peninsula and manoeuvred onto footings by mammoets. Timing of the civil works to coincide with PAM shipments was crucial.

Ryan Surveys had to ensure control, the accurate set out of civil works, provide “as constructed” surveys of PAMs, ensure accurate positioning of PAMs, and provide dimensional surveys and “as constructed” reports.

Tom’s Gully Underground Gold Mine - Survey Project

Tom’s gully gold mine is an underground mine situated south east of Darwin along the Arnhem Hwy.

Ryan Surveys acted as Senior Mine Surveyor and undertook directional surveys and volume pick up of decline, drives and stopes as well as monthly production reports and volume calculations

LNG Plant Tank - Survey Project

The Wickham Point development, in the heart of Darwin Harbour, was a 1.2 billion dollar project building an export facility for the Bayu Undan gas fields. The facility required the construction of a refinery, storage tank and export wharf.

Ryan Surveys Director, in conjunction with the Thiess Process senior surveyor, ensured the accurate set out of all civil works, conducted “as constructed” surveys and established and monitored control for the storage tank site. Nicknamed the ‘giant esky’, this was the largest tank with a single span roof in the world and the largest tank in the southern hemisphere. It consisted of an inner metal compartment and an outer concrete sleeve, with 500mm thick cylindrical walls.

Overall, it was 35m high, 98m in diameter and 300m in circumference and required approximately 5250 cubic meters of concrete. The sheer size of this project made compliance to tolerances crucial, especially when the prefabricated roof was elevated from the tank floor and positioned.

Built off-site, the roof was deconstructed for transport, repositioned inside the tank and rebuilt. Air pressure was used to lift the roof from the floor to the ceiling through the use of high pressure fans, requiring that the gap between the walls of the tank and roof be sufficient to allow movement yet be sealable with a rubber membrane.
Guide wires controlled the ascent and the roof was raised 35m to its final resting place. Once in place the domed roof increased the height of the tank to approximately 52m.

Alice Springs to Darwin Railway - Survey Project

The Alice Springs to Darwin Railway required the provision of survey for approximately 80 minor bridges along the rail alignment from Alice Springs to Darwin. Minor bridge construction consisted of the placement of prefabricated concrete beams and prefabricated steel headstocks and piers.

The Minor bridge crew of approximately 40 workers, worked in teams of three to drive or set piers into concrete foundations and to cut and fix headstocks. Bridges varied from 3m – 15m in height and 5m – 500m in length.

The Director acted as Senior Surveyor and established secondary control along the rail alignment for bridge location, set out pile and headstock locations, and produced pile and headstocks “as constructed” reports. This project finished six months ahead of schedule.
