Structural Design for New and Existing Assets
TULLOCH provides structural engineering for new construction, renovations, rehabilitation, and asset renewal. Our teams design and assess buildings, bridges, foundations, support structures, and other assets using wood, steel, concrete, and masonry, with consideration for site conditions, project requirements, and long-term use.
Why Work With TULLOCH?
Technical Insight for Structural Challenges
Constructability First
Designs consider materials, access, erection, sequencing, conditions, and installation requirements before work reaches the field.
Flexible Design Approaches
New structures, retrofits, and rehabilitation measures account for changing loads, operations, future modifications, and site constraints.
Assessment-Led Direction
Evaluations, calculations, and modelling establish current capacity and help define the need for repair, strengthening, modification, or replacement.

Structural Engineering FAQs
Useful information may include original drawings, previous reports, renovation records, photographs, known damage, proposed modifications, and current or future loading requirements. TULLOCH can help identify additional investigation needs during scoping.
Potentially. Our team evaluates condition, capacity, deterioration, access, constructability, cost, and intended service life to compare repair, strengthening, rehabilitation, and replacement options. The appropriate approach depends on the structure and project objectives.
The design may consider temporary support, sequencing, access restrictions, shutdown windows, existing equipment, occupant needs, and contractor staging. These requirements are established with the owner and project team before detailed work proceeds.
A peer review may be useful for complex designs, unusual structural systems, significant modifications, temporary works, or projects requiring an independent technical perspective. The scope can range from targeted calculations to a broader review of drawings and design assumptions.
Yes. Depending on the assignment, the team may use field measurements, visual investigation, material testing, scanning, selective openings, and engineering analysis to establish enough information for an assessment. Some uncertainty may remain where concealed conditions cannot be verified.
