Our Process


Meet with customer

Before we commence with any new project, we first arrange a convenient time to meet with the customer to understand the project requirements. This is an integral part of the process to ensure clarity around the scope and specific details of the project or works to be undertaken. For landscaping projects, we will discuss design ideas, concept plans, garden planting plans, construction plans, project site and any limitations. For building maintenance works it’s important to take a systematic approach, so scope and scale of the works can be determined, such as corrective maintenance, planned maintenance, emergency repairs, housekeeping maintenance and any other requirements.


Obtain customer approval

Once the scope and scale of a project has been discussed and all relevant details have been obtained, our team will get to work on the design, creating plans and drawings to bring to life the visualisation of the customer’s ideas and requirements, plus relevant quotes for works to be completed. This may require agreements, schedules and costing. This is the opportune time for the customer to review, amend and finalise the scope of project/works to be completed.


Sign off by customer

This stage in the process is the opportunity for GMS Contractors and the customer to get together again, to finalise and approve any amendments to project plans and/or agreements and to be absolutely certain that all parties agree on all aspects of the project/works to be undertaken.


Project scheduling

With an agreement having been reached and signed-off by the customer for project/works to be completed, it is time to get things underway. This is where we discuss with the customer a suitable commencement date, and the expected completion date. At this stage we will have already met with our key people and network of experienced contractors and scheduled all the various stages of the project/works.


Regular ongoing feedback

Once a project has commenced, we will provide regular, ongoing feedback and updates to the customer, so they remain fully informed as the project progresses. GMS provide regular updates as each milestone is achieved, what will happen next and the expected timeframe for each stage, always keeping in mind the agreed schedule for completion of the project/works. In the rare case if a delay should occur beyond our control, then the customer will always be fully informed of this as well, with a plan on how we intend to manage or rectify any delays or issues.


Final meeting and signoff

Once all works have been completed, we will then schedule a meeting suitable to the customer so they can visit the site and view the final result. At this time, we will show the customer around the site and go through the project plans and specifications in detail to ensure everything has been completed to their full satisfaction, for final sign off by all parties.


GMS Contractors are insured up to $25m in Public Liability and all of our works come with a proprietary warranty*
