Renovations

Structural Engineering for Renovations
Every successful renovation begins with the right structural insight. At Bold Engineering, we specialize in structural engineering for renovation, helping you transform existing buildings into modern, functional spaces. We assess structural capacity, evaluate proposed changes, and guide projects through safe, code-compliant upgrades. Whether you’re removing walls, adding new floors, or reconfiguring interiors, our team brings clarity and confidence to every step of your renovation.
Structural Evaluation & Feasibility
Before you remove a beam or open a wall, you need to know what you’re working with. We conduct detailed structural investigations to assess foundations, framing, load paths, and material condition. We review original drawings and perform targeted inspections or tests. This helps you understand what changes the building can accommodate without compromising safety or performance.
We’ll translate that assessment into clear guidelines, what can be removed, where you can extend, and how to adjust loads, so your design stays supported and compliant.
Structural Modifications & Reinforcements
Your renovation may involve opening up walls, adding floors, or increasing window sizes. We design new beams, lintels, or columns and verify floor/roof capacity. If foundation upgrades, underpinning, or concrete repairs are required, we handle that too. For heritage properties or unique structures, we propose minimally invasive solutions that maintain character.
We model loads using advanced analysis software and define reinforcement needs to match the new design, ensuring that modified areas perform as intended.
Structural Rehabilitation & Restoration
Older buildings often carry hidden defects: settlement cracks, rot, corrosion, or outdated construction. We perform condition assessments and recommend rehabilitation measures, including carbon fibre reinforcement, concrete jacketing, steel plating, or foundation underpinning. Our methods address structural issues without overbuilding and while preserving the structure’s character.
Adaptive Reuse & Additions
Bringing new life to old buildings? We help you modify existing structures for new functions, like converting offices into apartments or adding mezzanines. We verify load capacity, design connections between old and new, and model diaphragm continuity and lateral stability. That means your new space works with the existing building rather than fighting it.
Coordination & Site Support
Good design only delivers value with proper implementation. We coordinate with consultants and contractors during demolition, shoring, formwork, and reinstatement. Our engineers visit the site to check progress, answer questions, and confirm structural elements are built as intended. That support keeps timelines smooth and quality high.
Permit & Code Compliance Support
Renovations often require navigating municipal permits, heritage approvals, and compliance with evolving codes. We prepare and submit stamped structural drawings and calculations that align with the Ontario Building Code and municipal requirements, streamlining your permit process. Our engineers liaise with city officials and building inspectors to address questions efficiently, helping to avoid delays. Whether your project involves a single-family home or a large commercial renovation, we help keep your renovation legally compliant and moving forward.
Sustainability & Energy Retrofit Integration
Structural renovations are the perfect time to integrate energy upgrades that reduce long-term operating costs and environmental impact. We assess structural implications of adding solar panels, upgrading insulation, or installing green roofs to enhance building performance. Our team collaborates with mechanical and envelope consultants to support airtightness improvements and thermal upgrades without compromising structural integrity. This holistic approach helps you align your renovation with sustainability goals and future operational savings.

Frequently Asked Questions
Here are answers to common questions about renovation structural engineering. If your question isn’t listed, get in touch and we’ll help you.
It’s the evaluation and design work needed to modify an existing building’s structure, like walls, foundations, and framing. This process helps ensure that the building can handle new loads or layouts safely. It also identifies potential challenges before construction begins so you can plan your renovation with confidence.
Yes. Even non-load-bearing walls can affect lateral stability or cause unforeseen issues; a professional review is essential. We assess load paths and framing to confirm if removal is safe and recommend alternatives if structural support is needed.
We inspect visible elements, review drawings, test materials as needed, and model loads to evaluate capacity. This process helps identify deficiencies that could affect the renovation. We also document structural risks so you can address them during planning.
We sometimes design underpinning or slab strengthening to meet new load demands. This can involve adding piers or reinforcing with additional concrete. Our goal is to provide a practical solution that protects your building while supporting your renovation plans.
Yes. We design sympathetic solutions that preserve character and adapt older structures for modern use. We also review masonry condition and compatibility with new materials to avoid damage during renovations.
For modest interior renovations, the structural stage can take 2–4 weeks. Complex projects may take longer. We provide a clear timeline at the start of your project to help you schedule trades and construction activities.
Yes, we do. We’ll coordinate demolition, shoring, formwork, and framing to help your contractor follow the design. On-site visits help us address any unexpected site conditions quickly to keep your project moving.
Yes. Any structural change needs stamped drawings and calculations submitted to the municipality. These documents demonstrate compliance with building codes and help secure permits faster.
Yes. We evaluate framing, load transfers, connections, and foundations for new structural components. Our team ensures the design integrates with your existing building and meets code for safety and long-term performance.
