Tendering is more effective when builders have a clear, consistent basis for pricing the work.

Before issuing tender documents, it’s worth checking whether the scope, quantities and cost assumptions are sufficiently developed to support meaningful comparisons.

A pre-tender quantity surveying process may include:

✓ Measuring and documenting quantities
✓ Preparing a structured Bill of Quantities
✓ Reviewing scope alignment and key assumptions
✓ Identifying potential gaps for clarification
✓ Establishing a basis for tender comparison

Once tenders are received, this groundwork can help the project team review differences, investigate pricing outliers and assess the submissions more systematically.

It won’t guarantee that every builder returns the same price. It can, however, make the reasons for different prices easier to understand.

At AUBC Consulting, our quantity surveying and cost management services support informed decisions from early planning through to tender and construction.

A development application budget is an important planning tool. But it shouldn’t be treated as a guaranteed construction price.

As a project progresses from planning towards tender, details become clearer, design decisions evolve and market pricing may change.

The difference between the early budget and the tender return can reflect several things:

• The level of design detail available when the budget was prepared
• Changes to specifications, quantities or scope
• The assumptions used for rates and allowances
• Escalation between estimating and tendering
• Risks that were not fully quantified at the earlier stage

The key is to maintain a clear connection between the original budget, subsequent design changes and the latest cost forecast.

Regular cost reviews can help project teams identify emerging gaps earlier and assess options before commitments are made.

The lowest tender isn’t always the easiest to compare, and the highest tender isn’t automatically unreasonable.

Before making a decision, look closely at three areas:

𝟭. 𝗦𝗰𝗼𝗽𝗲 𝗴𝗮𝗽𝘀 𝗮𝗻𝗱 𝗲𝘅𝗰𝗹𝘂𝘀𝗶𝗼𝗻𝘀
Are all tenderers pricing the same work? Missing items can create additional costs later.

𝟮. 𝗣𝗿𝗼𝘃𝗶𝘀𝗶𝗼𝗻𝗮𝗹 𝘀𝘂𝗺𝘀 𝗮𝗻𝗱 𝗮𝗹𝗹𝗼𝘄𝗮𝗻𝗰𝗲𝘀
Are allowances based on comparable assumptions, and how much uncertainty remains?

𝟯. 𝗤𝘂𝗮𝗻𝘁𝗶𝘁𝗶𝗲𝘀 𝗮𝗻𝗱 𝗿𝗮𝘁𝗲𝘀
Are quantities consistent? Where rates differ, is there a clear explanation?

A structured tender review helps identify differences that may otherwise be overlooked when comparing only the total price.

This is where a properly prepared BoQ and a systematic tender analysis can add value.

When a builder explains a higher tender price by citing supply delays, it’s worth looking beyond the headline figure.

Supply constraints may affect material pricing, lead times, procurement schedules and the sequence of construction activities.

But what does that mean for your specific project?

Consider asking:
- Which materials or trades are affected?
- Are the quoted rates based on current supplier pricing?
- Are alternative materials or suppliers available, subject to approval?
- Could extended lead times affect preliminaries or the construction programme?
- Which costs are confirmed, and which remain allowances or assumptions?

These questions help distinguish genuine project risks from items that require further clarification.

The objective isn’t to dismiss a builder’s concerns. It’s to understand the evidence, quantify potential impacts and make informed decisions.

When builders submit tenders for the same development, their prices may differ significantly.

But are you comparing the same scope of work?

A 𝗽𝗿𝗲-𝘁𝗲𝗻𝗱𝗲𝗿 𝗕𝗶𝗹𝗹 𝗼𝗳 𝗤𝘂𝗮𝗻𝘁𝗶𝘁𝗶𝗲𝘀 (𝗕𝗼𝗤) provides a structured breakdown of measured work items and quantities to help tenderers price against a consistent basis.

It can help project teams:
• Identify differences in pricing across work items
• Review rates and quantities more systematically
• Spot potential scope gaps and exclusions
• Compare tender submissions on a more consistent basis

For Sydney developers, this can be particularly useful when evaluating multiple tender submissions in a changing construction market.

A BoQ cannot eliminate every pricing difference or guarantee the lowest tender. Its value is in making those differences easier to identify, question and assess.

Your development has progressed through planning, your DA budget is set, and then the tender returns arrive.

The numbers are 20% higher than expected.

The immediate temptation may be to value-engineer the design or negotiate with builders. But first, it’s important to understand why the gap exists.

Potential factors include:

• Design development since the original estimate
• Different scope assumptions across tenderers
• Changes in material, labour or subcontractor pricing
• Provisional sums and exclusions
• Market conditions and construction timing

Without a clear cost breakdown, it can be difficult to determine whether the issue is pricing, scope, or the original budget assumptions.

It can.

When properly implemented, BIM can help connect design information with quantities and cost data.

For quantity surveyors and project teams, this can provide greater visibility into how design changes may affect:

• Quantities
• Materials
• Cost
• Programme
• Procurement

The important word is "𝗰𝗮𝗻."

Technology doesn't automatically create cost certainty.

The quality of the information, the way the model is managed and the expertise interpreting it all matter.

Construction documentation has changed dramatically.

Traditional projects relied heavily on 2D drawings and manually coordinated information.

Today, Building Information Modelling (BIM) allows project teams to create detailed digital representations of buildings and coordinate information across disciplines.

For cost professionals, this can create new opportunities to connect:

𝗗𝗲𝘀𝗶𝗴𝗻 → 𝗤𝘂𝗮𝗻𝘁𝗶𝘁𝗶𝗲𝘀 → 𝗖𝗼𝘀𝘁𝘀 → 𝗣𝗿𝗼𝗷𝗲𝗰𝘁 𝗗𝗲𝗰𝗶𝘀𝗶𝗼𝗻𝘀

BIM isn't simply about creating a 3D model.
Its real value comes from connecting information.

And when better information is available earlier, project teams can make better-informed decisions.

Before a project can be properly costed, someone needs to understand 𝘄𝗵𝗮𝘁 𝗶𝘀 𝗮𝗰𝘁𝘂𝗮𝗹𝗹𝘆 𝗯𝗲𝗶𝗻𝗴 𝗯𝘂𝗶𝗹𝘁.

Quantity takeoff is the process of measuring and quantifying the materials and components shown in project documentation.

Modern digital tools can help quantity surveyors:

• Measure directly from digital drawings
• Quantify materials faster
• Reduce manual measurement
• Improve consistency
• Update quantities as designs change

But software is only part of the equation.
