In complex remediation, uncertainty is your most expensive line item. This article explains why “getting quotes” is the wrong first step, and how investing in the right investigation upfront protects your owners from budget blowouts later.

This is blog three in a series of five that I’ve written based on my experience leading remediation projects at Context. Based on my background in architectural design and project delivery, I’ve seen too many Body Corporates rush into pricing before understanding the problem.

Introduction

For many Body Corporate committees and commercial asset managers, the natural instinct when facing a building defect—whether it is weathertightness, seismic vulnerability, or aging services—is to ask the market: “How much will this cost to fix?”

It seems like a prudent governance step. You have a fiduciary duty to the owners to spend funds wisely, so getting three quotes appears to be the logical way to establish market value. However, in the complex world of multi-unit remediation, engaging the market too early often has the opposite effect.

When you ask for a price without first investing in a rigorous diagnostic investigation, you are not buying a solution; you are buying a set of assumptions. If those assumptions are wrong, the “fixed price” contract you sign today will become a series of variation claims tomorrow.

This article outlines why the traditional “quote-first” procurement model is failing New Zealand bodies corporate and how to structure your investigation phase to ensure you are comparing apples with apples, not apples with “we’ll figure it out on site.”

Why “Quote-First” Procurement Backfires

The remediation sector is currently navigating a period of high complexity. With the Unit Titles (Strengthening Body Corporate Governance and Other Matters) Amendment Act 2022 now fully in force, large developments (10+ units) are under immense pressure to provide accurate 30-year Long-Term Maintenance Plans (LTMPs).

When a committee rushes to market to satisfy these planning requirements or to fix an urgent leak, they often issue a tender based on high-level symptom descriptions rather than detailed forensic data. This creates three specific financial risks:

1. The Risk Premium vs. The Variation Trap

Contractors are rational. If the scope of work is unclear (e.g., “repair facade leaks”), they have two choices.

• The Risk Premium: They can price in every conceivable worst-case scenario (rotting timber, structural steel corrosion, fire compliance upgrades). This results in an astronomically high quote that scares the owners and stalls the project.
• The Variation Trap: They can price only what they can see, excluding “latent conditions.” This results in a low, attractive headline price. However, once the scaffolding is up and the cladding is removed, every discovery becomes a chargeable variation.

The latter scenario is far more common and far more dangerous. It leads to projects starting with a $2 million budget and ending with a $4 million actual cost, leaving the committee scrambling to raise special levies from owners who have already reached their financial limit.

2. The False Comparison (Apples to Oranges)

Without a tight, technically defined scope, every tenderer will solve the problem differently. One might propose a full reclad to meet current H1 Energy Efficiency standards. Another might propose a targeted patch repair that ignores the underlying ventilation issues.

As a committee, you cannot compare these prices because they are not delivering the same asset outcome. One represents a 15-year lifecycle extension; the other might fail again in five years.

3. The “Discovery Gap”

Traditional investigations often rely on visual inspections or limited invasive testing. This leaves a massive “discovery gap”—the difference between what you think is wrong and what is actually wrong inside the wall cavity. In high-risk multi-unit dwellings, failure rates for certain cladding systems are statistically high. Relying on a visual inspection to price a repair on a complex building is like a surgeon quoting for heart surgery based only on a conversation with the patient.

What “Good Evidence” Looks Like

Before you ask a construction company for a price, you must invest in “uncertainty reduction.” This means shifting your mindset from “paying for repairs” to “paying for data.”

Modern remediation strategies are moving away from manual measure-ups and toward Digital Diagnostics. While specific technologies vary, the standard of care for a large complex should now include:

• A “Digital Twin” or Baseline: High-fidelity 3D scanning (using Lidar or similar tools) creates a millimetre-accurate record of the building as it is, not as it was drawn in the 1990s. This eliminates the “information asymmetry” where contractors claim dimensions were wrong and charge for the difference.
• Defensible Scope Definition: You need a diagnostic report that defines not just the defect, but the boundaries of the repair. Does the window replacement trigger a fire rating upgrade? Will removing the cladding trigger a requirement to upgrade insulation to the new H1 standards?
• Sequencing Logic: Good evidence includes a plan for how the work can be done in an occupied building. If the investigation doesn’t consider how trades will access a fourth-floor balcony without evicting the tenant, the price you receive will be invalid.

Questions to Ask Your Advisor or Contractor

If you are interviewing project managers, building surveyors, or lead consultants, do not just ask them about their rates. Ask them how they manage uncertainty.

1. “How will you prove the scope, not just assume it?”

Push for details on their diagnostic phase. Will they use non-invasive testing? 3D capture? Destructive testing? If their answer is “we will take a look and give you an estimate,” you are inviting scope creep.

2. “How do you manage the intersection of different codes?”

Remediation is rarely just about waterproofing. It crashes into structural (seismic), fire, and acoustic regulations. Ask them how their investigation coordinates these disciplines before the tender goes out. You want to avoid the scenario where the waterproofer finishes, and then the fire engineer says the wall needs to be opened up again.

3. “What is your variation management protocol?”

Even with the best diagnosis, some unknowns will remain. Ask for a specific workflow: How are variations flagged? What evidence is required to prove it is a “new” issue and not something they should have seen? Who has the authority to approve it?

4. “How will you keep our building insurable during the works?” Insurers are increasingly risk-averse. A “patch” strategy that leaves systemic issues unresolved may result in the building becoming uninsurable. Your advisor should be able to articulate how the proposed investigation provides the “Governance Baseline” evidence required by underwriters.

Decision Support Artefacts: Tools to Reduce Conflict

Finally, the investigation phase should deliver more than just a technical report. It should provide the committee with tools to manage the politics of the owner group.

When you are ready to select a solution, you should have:

The Disruption Map: A visual guide for owners showing which units will be affected, when, and for how long.

The Options Matrix: A clear table comparing 2-3 remediation pathways (e.g., Target Repair vs. Full Reclad). This should compare not just cost, but “Expected Life,” “Maintenance Liability,” “Insurability,” and “Disruption Level.”

The Risk Register: A living document that lists the “Known Unknowns” (e.g., “Likelihood of timber decay in the north elevation”). This allows you to set a scientifically calculated contingency fund, rather than guessing “plus 10%.”

Frequently Asked Questions

What reports do we need before requesting remediation quotes?

At a minimum, you should have a comprehensive condition assessment that identifies the root cause of failures, not just symptoms. For large complexes, a “Digital Diagnostic” or 3D scan is recommended to ensure accurate quantities (square metres of cladding, linear metres of flashing) so tenderers price the exact same scope.

Why do remediation quotes vary so much?

Quotes usually vary because the scope is ill-defined. One contractor may be pricing for a “worst-case” scenario including extensive timber replacement, while another is pricing a “best-case” surface repair. This is why you must define the scope before tendering.

How do we avoid variation blowouts?

You cannot eliminate them entirely, but you can mitigate them by investing in front-end diagnostics. The more you “open up” (digitally or physically) before the contract is signed, the fewer surprises you will find later. Ensure your contract has a strict variation approval process.

Can we just fix the leak without upgrading the whole building?

Sometimes, but be careful. The Building Act requires that any substantial work must consider the building as a whole, particularly regarding fire and accessibility. Furthermore, fixing a leak without addressing ventilation or insulation can sometimes lead to “sick building syndrome” or other moisture issues.

Next Steps

IIf your committee is currently debating whether to “just get quotes” or invest in a deeper investigation, pause the process and establish your baseline requirements first.

1. Create an “Evidence Brief”: Instead of a scope of works for a builder, write a brief for an investigation. List the symptoms you see, the gaps in your current data (e.g., “we have no as-built drawings”), and the decisions you need to make.
2. Standardise Your Procurement: When you do go to market, ensure every vendor is pricing the same risk profile. Ask them to separate “Base Build” costs from “Provisional Sums” for specific risks.
3. Review your Long-Term Maintenance Plan (LTMP): Check if your LTMP is based on a generic spreadsheet formula or actual building condition data. If it is the former, your investigation needs to feed back into this plan to ensure you are compliant with the 30-year planning horizon required by the Unit Titles Amendment Act.

By treating the investigation as a distinct project phase—one where you are buying certainty rather than construction—you protect your owners from the financial shock of a project that spirals out of control.
