Our Services

Cornerstone Estimating Pty Ltd provides commercial management and construction estimating services for subcontractors across Melbourne, VIC. Our services are designed for finishing and architectural trades who want better control over contracts, variations, margins and cash flow. By staying involved before and during delivery, we help subcontractors manage risk properly, protect profit and keep projects commercially stable from start to finish.

Construction profitability fails commercially when decisions are made without clarity, structure or support. Verbal instructions, unclear scope, rushed claims, and unmanaged change quietly erode margins and place pressure on cash flow. Our role is to bring structure to these areas so subcontractors can operate with confidence rather than reacting to problems after the damage is done.
Cornerstone Estimating Pty Ltd takes a practical, project-focused approach by working alongside subcontractors during live jobs, not after disputes have already formed. This allows issues to be identified early, managed properly, and resolved while leverage still exists. Our construction estimating company in Melbourne, VIC offers a comprehensive range of Quantity Surveying and Contract Administration services designed to support Construction Businesses throughout every phase of a project. 
All services are delivered by a qualified, experienced Quantity Surveyor and Contracts Administrator, with deep experience in the Construction industry. Whether you need to win more tenders, get paid on time, or protect your margins, our solutions are tailored, thorough and grounded in real-world commercial practice.

Commercial Management

Commercial management is the backbone of how subcontractors stay in control during a project. Without ongoing oversight, small decisions made under pressure can create long-term financial exposure. Issues such as unclear responsibility, untracked changes, and delayed responses often compound over time.
We provide ongoing commercial support throughout the project lifecycle, helping subcontractors understand their position, assess risk, and respond appropriately as the job progresses. This guidance allows work to continue without sacrificing margin or taking on unintended exposure. 

This service would be covered in varying capacities across our Tier 1, Tier 2 and Tier 3 pricing packages (see Our Pricing section below), which would be $2,000/month (Excl GST) (Tier 1), $4,000/month (Excl GST) (Tier 2) and $7,500/month (Excl GST) (Tier 3) respectively.

Contract and Scope of Works Review

Contracts and scope documents often contain hidden risks, unclear inclusions, and poorly defined exclusions. When these issues aren’t understood early, subcontractors can end up responsible for work they never allowed for.
We review contracts and the scope of work to clarify obligations, risks, inclusions, and exclusions. This creates a clear commercial baseline that allows projects to be managed properly and decisions to be made with full awareness of exposure.

This service would start from our Tier 1 pricing package (see Our Pricing section below), which would be $2,000/month (Excl GST).

Variation and Change Management

Change is constant in construction, but unmanaged change is costly. Many subcontractors lose money by proceeding with variations based on verbal instructions or assumptions, only to discover later that approval or payment is disputed.
We help identify changes early, price them correctly, and ensure they are documented and approved before work is carried out. Managing variations at the right time preserves leverage, reduces disputes and prevents subcontractors from funding changes out of their own pocket.

This service would start from our Tier 2 pricing package (see Our Pricing section below), which would be $4,000/month (Excl GST)

Margin and Cash Flow Protection

Strong margins and stable cash flow are the result of consistent commercial processes. Subcontractors often experience cash flow pressure due to under-allowed tenders, poorly prepared claims or unchallenged payment schedules.
We support margin and cash flow protection through estimating, tendering, contract management, and payment claim preparation aligned with the Building & Construction Industry Security of Payment Act (SOPA). We also review payment schedules and guide responses when amounts are reduced or delayed, including escalation to adjudication when required. This helps subcontractors stay paid correctly and on time.

This service would start from in our Tier 3 pricing package (see Our Pricing section below), which would be $7,500/month (Excl GST).
