3.1-a Boyne Smelters

Carbon Area

Site office Aestec have set up a site office at Boyne Smelters at our own cost, we are also working with Chris Harp to set up access to a desk at Yarwun, advantages to client are:

1. Allow prompt service to the client. 2. Ease of management of Aestec site crew

Aestec are willing to set up site office at QAL if awarded the contract


Contractor laydown area

Site container Aestec site containers are set up to run our daily toolbox meeting, we have adopted the Lean methodology and have embedded 5S in our containers/workshops and storage yards. All members of our team are involved in using, auditing and improving the 5S of these areas. Each day each team member checks his or her accountable area and makes any changes or improvements as required.


South East corner line 3

Site laydown yard Our site laydown area is set up to store items regularly required for site use e.g. Expansion joint material, form work etc. Aestec purchase a lot of material in bulk and store it in the site specific lay down areas. This allows Aestec to pass on the reduced cost associated with bulk purchasing and reducing the overall freight costs.

South Gladstone Reservoir

Exposed steel ready for treatment and repair of concrete

Spall areas where identified and chipped back to rebar removing all poor quality concrete. It was found that the ‘drummy’ area of concrete extended well beyond the obvious spall. Chipping along the rebar showed that the corroded rebar extended deeper into the concrete in all cases and non-corroded reinforcement was not found. The chipping back was stopped and client contacted to make decision of repair or removal of parapet wall. (Parapet wall was removed)

Concrete repair (completed with no impact to operations)

1. Divert all effected services (water, air, HV and LV cables) 2. Remove wall cladding and HV cable tray protection 3. Saw cut concrete to allow for safe removal of wall 4. Use excavator to demolish concrete wall 5. Prepare bonding surface and install 16mm rio 6. Install formwork and brace it ready for pour 7. Place and finish concrete including curing 8. Remove form and install all original cladding and services 9. Hand work area back to operations

Expansion Joint repairs

Aestec have set up a trailer specifically for expansion joints, this allow us to repair the joints in the required time frame to ensure we do not compromise the reduction line operations. Aestec work with the operations planner each week to plan the joint repairs around the operations miss areas. Aestec team members have a very good understanding of the Reduction Line and ensure safe work practices are followed. Aestec has worked with the repair product supplier to establish the best repair method for this specific application, this was done to extend the life of the repair

Jig design to reduce work time

Value in use Aestec designed a jig to support the core drilling machine in the exact location to drill the holes required so there was no measuring required, this saved an average of 15mins per hole for 160 holes Saving of $6,400.00. The core drill jig is clamped onto the existing concrete beams at the location of a new steel rafter support bracket. The drill is held in position using a customized ergonomic jig.

Set up of site container

Value in use Aestec Currently transports all items to site, most of the time requiring more than 1 trip to collect all tools and materials. With Aestec Storing the common items on site, this would reduce travel and increase production. 2 additional trips / day: 2 men 1.5 hrs / trip. $53.00 x 2 men x 1.5hrs x 2 trips. $53 x 2 x 1.5 x 2 = $318.00 / day Currently applies at least 2 day/ week. 52 weeks / year x 2 occurrences 52 x 2 x $318.00 = $33,072.00

Reduction line 1 and 2 deline shed

Replaced door Value in use The South roller door was continually being damaged by the 20Tonne excavator so instead of continually repairing the door Aestec designed and relocated the mounting structure from inside the shed to the outside of the shed this has reduced the damage. Estimated saving of $20,000.00 per year

Cost saving initiative implemented

Value in use

Aestec Supervisor having clearances signed prior to toolbox meeting

There are times an Aestec team is required to wait for the affected area owner to complete their morning task prior having the clearance signed this is costly for the client and frustrating for the contractor, as a result Aestec supervisors have clearance certificates signed by affected area owners prior to start of shift, this eliminated down time for the Aestec crew allowing our team to be produc-tive earlier.

Installation of roof Purlins

Value in use The purlins detail to be used in this project were to be 450g/m however using that type of coating system would not receive any warranty, Aestec negotiated with Strammit to supply ZAM coated purlins for the same price as the 450g/m coating which was a saving $8000.00. Zam coated purlins give a 15 year warranty which was passed on the client at no extra cost. The Down turned lip lapped zed purlins installed on rafters via the work platform.
