R&D Tax Incentive for Construction and Engineering Companies
Construction and engineering companies do genuine R&D. The challenge is that the sector attracts ATO scrutiny, carries a statutory building exclusion that limits what can be claimed, and requires on-site documentation that most project teams are not set up for. We help you navigate all three.
Does Construction and Engineering R&D Qualify for the RDTI?
Yes, but with important constraints that are unique to this sector.
The R&D Tax Incentive applies to any Australian industry where activities meet the three core criteria: genuine technical uncertainty, systematic experimentation, and the generation of new knowledge. Construction and engineering companies regularly undertake work that satisfies these criteria, particularly in structural innovation, novel material trials, ground improvement under unusual conditions, and emerging construction technologies.
The critical distinction is between applying known engineering principles to a new context and genuinely not knowing whether a technical approach will work before conducting experiments. The former is competent engineering. The latter is potentially eligible R&D. The test is whether a competent professional in your specific field, for instance, a structural engineer or geotechnical specialist at the frontier of their discipline, could have determined the outcome without systematic experimentation.
Two RDTI constraints apply with particular force in construction:
- Technical uncertainty: The outcome must not be known or determinable in advance, even by a specialist at the frontier of the relevant engineering discipline, not just a generalist practitioner
- Systematic experimentation: Work must follow a hypothesis, test, observe, evaluate cycle. On-site problem-solving without a structured experimental approach does not satisfy this test
- New knowledge: The R&D must generate knowledge not previously available in the public domain, not just knowledge that is new to your company or new to this project
- Building exclusion: Expenditure on acquiring or constructing a building, including extensions, alterations, or improvements, is explicitly excluded by the legislation, even if R&D is conducted during construction
Understanding the full scope of RDTI eligibility requirements is the starting point for identifying what in your construction or engineering work genuinely qualifies.
Construction R&D: What Qualifies and What Doesn't
The line between eligible R&D and routine construction work is drawn at technical uncertainty, not complexity or cost. The most technically demanding projects can be ineligible, and relatively contained experimental activities can qualify. What matters is the nature of the uncertainty and the structure of the experimentation, not the scale of the project.
✅ LIKELY QUALIFIES:
- Developing novel formwork or falsework systems where structural performance under specific loading conditions cannot be predetermined using existing engineering methods
- On-site trials of composite or recycled material blends in structural applications where strength, durability, or long-term performance characteristics are uncertain before testing
- Adapting ground improvement or foundation techniques to unusual geotechnical conditions where standard approaches are demonstrably inadequate and outcomes are unknown in advance
- Developing custom prefabrication methodologies for complex or non-standard building geometries where connection behaviour, tolerances, or assembly sequencing is genuinely uncertain
- Experimental deployment of robotic or automated construction processes, such as automated rebar placement or concrete spraying systems, where performance characteristics on live construction sites are not established
- Developing innovative structural monitoring or sensing systems integrated into built assets where the technical feasibility of achieving required precision is uncertain
❌ DOES NOT QUALIFY:
- Standard structural or civil design using established engineering principles, codes, and software, even for complex or high-value projects
- Applying manufacturer-specified materials or proprietary systems in line with documented specifications and installation guides
- Routine project management, site administration, construction scheduling, or quality management activities
- Ordinary cost-reduction through process efficiency improvements where the technical approach is known and the outcome is a matter of execution, not experimentation
- Expenditure on the building structure itself: foundations, structural elements, fitout, extensions, or improvements are excluded by statute regardless of whether R&D occurs during construction
For guidance on how eligible R&D expenditure is calculated, including staff costs, materials, and contractor payments, see the R&D Tax Incentive overview.
What's Different About Construction RDTI Claims
Construction R&D claims involve challenges that do not arise in most other sectors. These are the areas that most commonly cause claims to be challenged, reduced, or disallowed, and the ones we focus on most closely when working with construction and engineering clients.
The building acquisition and improvement exclusion
The RDTI legislation explicitly excludes expenditure incurred to acquire or construct a building, or part of a building, including extensions, alterations, and improvements. This is a statutory exclusion, not a discretionary one, and it applies even when genuine R&D is conducted during a construction project. A construction company that develops a novel formwork system during a building project cannot claim the cost of the building itself, only the costs specifically attributable to the R&D activity: the experimental time, the materials consumed in trials, the specialist testing, and directly related contractor costs. Separating these from overall project expenditure is technically demanding and requires a defensible allocation methodology established before lodgement.
ATO compliance focus on construction
The ATO and AusIndustry have both publicly identified the construction sector as a compliance priority. Common issues flagged in reviews include whole-of-project claims where the R&D components are not clearly delineated, activities described in commercial or project-delivery terms rather than technical terms, and insufficient evidence that technical uncertainty existed at the time work commenced. Construction claims must be described in technical language that explains what was unknown, what was systematically tested, and what was learned. "We solved a difficult engineering problem" is not a basis for an RDTI claim. "We did not know whether the proposed hybrid connection detail would achieve the required moment capacity under cyclic loading, and we conducted a programme of physical testing to evaluate three candidate configurations" is closer to the framing required.
On-site documentation and the pace of construction
Construction sites move quickly. The ATO gives significant weight to contemporaneous documentation, meaning records made at the time the R&D was conducted, not reconstructed from memory afterwards. For on-site experimental work, this means site diaries with entries specific to R&D activities, photographic evidence of experimental configurations separate from routine progress photographs, test reports and material analysis results, and time records distinguishing R&D activity from general construction labour. Companies that begin documenting after a project is complete face significant evidentiary challenges, regardless of how genuine their R&D was.
Whole-of-project claims are a common failure point
Construction companies sometimes attempt to claim an entire project as R&D on the basis that the project as a whole involved innovation. AusIndustry does not accept whole-of-project claims. Each registered R&D activity must independently satisfy the core and supporting activity definitions. A project may contain multiple qualifying activities, but each must be individually identified, described, and substantiated. The expenditure claim must then be allocated to those specific activities, not applied across the project as a whole.
How We Help Construction and Engineering Companies
Building Exclusion Analysis
We work through the statutory building exclusion with you before any claim proceeds. This means identifying which expenditure is genuinely attributable to R&D activities, which is excluded as building work, and establishing a cost allocation methodology that is defensible under ATO review. Getting this wrong at the outset is the single most common reason construction claims are reduced.
On-Site Documentation Systems
We help construction and engineering teams set up contemporaneous record-keeping processes before projects begin, not after. This includes activity log templates, photographic evidence protocols, time recording frameworks, and guidance for site engineers and project managers on what needs to be captured and why. Evidence built during the project is far more valuable than evidence assembled retrospectively.
Activity Scoping and Technical Narratives
We identify which activities across your construction and engineering projects involve genuine technical uncertainty and structure them as individual eligible R&D activities. Each activity description is written to articulate the specific uncertainty, the experimental approach, and the knowledge generated, using technical language aligned with AusIndustry's registration requirements rather than project-delivery or commercial framing.
Audit-Ready Claims
Construction R&D claims are reviewed at a higher rate than most other sectors. We build every claim assuming AusIndustry scrutiny will occur: activity descriptions are technically precise, expenditure allocations are documented and methodology is recorded, and supporting evidence is pre-assembled. If a review does occur, we manage the response. See our review defence service.
Construction RDTI: Frequently Asked Questions
We're developing a novel structural system for a complex project. Does it qualify as R&D?
It depends on whether genuine technical uncertainty existed when work began. If a competent structural engineer in your specific field could not have determined the outcome without systematic experimentation, and you conducted structured trials with documented results, the activity may qualify. Routine structural design using established engineering principles and building codes does not meet the RDTI's technical uncertainty threshold, even when the project is complex or high-value. The distinction is between applying known methods to a new context and genuinely not knowing whether an approach will work before testing it. See our full eligibility guide for the core activity criteria.
How do we separate R&D costs from building costs under the RDTI?
The RDTI's building acquisition and improvement exclusion prevents you from claiming expenditure on the building structure itself, even when R&D is conducted during construction. You can only claim costs directly attributable to the R&D activity: time spent on experimental work, materials consumed in trials, and relevant contractor costs. Foundations, structural elements, fitout, and improvements are excluded regardless of any R&D conducted alongside them. This separation requires careful cost allocation and is one of the most common areas where construction claims are challenged. We help establish a defensible allocation methodology before work begins. See the RDTI overview for expenditure rules.
What documentation do we need for on-site R&D activities?
Contemporaneous records are essential and carry significantly more weight than retrospective documentation. For on-site R&D, you need daily or activity-level logs describing the technical problem, the uncertainty, what was tested, and what was observed. Site diaries, inspection records, photographic evidence of experimental configurations, test reports, and technical assessments from engineers or specialists all contribute. Time records linking employees to specific R&D activities rather than general construction labour are also required. The challenge in construction is that projects move quickly. We help put recording systems in place before work starts so evidence accumulates as the project progresses.
The ATO flags construction R&D claims. Should we be concerned?
The ATO and AusIndustry have both publicly identified the construction sector as a compliance focus area, with attention to whole-of-project claims and activities that lack genuine technical uncertainty. This does not mean construction companies should avoid claiming. It means the quality of your claim documentation is especially important in this sector. Weak claims attract greater scrutiny. Well-structured claims with precise technical descriptions, clear separation from excluded building work, and contemporaneous on-site records pass review without difficulty. The solution is not to avoid claiming; it is to build the claim correctly from the start. We build every construction claim ready for review.
Construction R&D Claims Built to Withstand Scrutiny
The building exclusion is real. The ATO scrutiny is real. But so is the R&D your team does on site. If you want to know what genuinely qualifies in your construction or engineering work, and how to claim it without the risk of a challenge, start with a structured assessment.
