Frequently Asked Questions

Find answers to common questions about our construction process, approvals, and what to expect when working with TrinityCon.

At TrinityCon, we deliver quality builds through expert coordination, clear communication, and a commitment to excellence. Our experienced team oversees every trade to ensure your project is completed on time, on budget, and to the highest standard.

We follow a structured 6-stage construction process:

Site Start & Slab Pour – Site preparation and concrete foundation
Framing & Trusses – Building the structural framework
Brickwork – Completing all external brickwork
Plasterboard – Installing interior walls and ceilings
Practical Completion Inspection – Final inspection before handover
Settlement – Official handover of your completed home

What you can expect:
• Weekly site inspections by your dedicated Site Supervisor
• Comprehensive quality audits at key milestones
• In-house Quality Team inspections throughout the build
• Client walk-throughs at Practical Completion and Settlement
• Additional site visits available by arrangement

At TrinityCon, we are built by trust, backed by quality.
A land easement is a legal restriction on your property title that requires a specific area of your land to remain free for a particular purpose, such as utility access or drainage.
A Development Application (DA) is submitted to your local council for approval before construction can begin. Each council has specific compliance requirements that vary depending on your location and block specifications.
TrinityCon coordinates all required building approvals to ensure your build proceeds as quickly as possible.

Required approvals from independent third parties include:
• Land developer approval (where applicable)
• Council approval
• Principal Certifying Authority (PCA)
• Architectural plans
• Structural engineering
• Hydraulic engineering (where applicable)
• BASIX – Energy and thermal assessment
• Sydney Water connection
• Power and gas connections
• Bushfire assessment (where applicable)
• Acoustic assessment (where applicable)
Once all Building Contract requirements are satisfied and final payments are received, we'll hand over the keys to your new home along with a comprehensive handover package containing all relevant documentation and warranties.
Council approval timeframes vary significantly between different councils, and as an independent authority, we have no control over their processing times. Your Pre-Construction Coordinator will regularly follow up on your application and provide updates once it's under assessment. You'll also receive a DA application number to track progress through your council's website.
Congratulations on securing your land! The next step is selecting a design. We can recommend one of our trusted architectural consultants, or we can provide a complete Design & Construct (D&C) service. We recommend spending time documenting your requirements and wish list before meeting with our team to determine what's achievable within your budget.
Excellent choice! To begin your project, we'll need:

Documentation & Agreements:
• All relevant contracts signed and agreed upon
• Confirmed costs with agreed start and completion dates

Payment Schedule:
Our progress claims are structured as follows:
5% – Initial contract signing
20% – Slab completion
35% – Structure, roof, and fit-out completion
25% – Enclosed to garage doors
10% – Final claim
5% – Retention release
Keys – Official handover

Your dedicated project coordinator will guide you through each step of the process.
