Integrated Design Approach
Our structural engineers work within the civil project delivery team from concept through to construction, ensuring seamless coordination at each stage.
Structural Engineering
Our structural engineering capability operates alongside civil engineering to deliver integrated infrastructure solutions.
We provide structural design and assessment services for water, sewer, transport, and community infrastructure projects across municipal, industrial, and commercial sectors.
This integrated approach supports project delivery through coordinated design, streamlined approvals, and construction-phase responsiveness.
Market Pressures & Risk Factors
Projects face coordination and delivery challenges when
civil and structural engineering are separated.
Civil infrastructure projects with structural components (retaining walls,
culverts, headwalls, pump stations) experience delays when external structural consultants are engaged after civil design is underway.
Design coordination issues arise when civil and structural teams work
independently – foundation conflicts with drainage, retaining wall alignments
that don’t match road geometry, last-minute design changes during
construction.
Construction programmes are disrupted when structural RFIs and shop drawing reviews are managed through external consultants with competing priorities.
Design development is constrained when structural input is not available during concept and feasibility stages, limiting options for value engineering and constructability improvements.
Project budgets and programmes carry risk when structural scope is identified late or assessed by consultants unfamiliar with local authority requirements and site constraints.
Structural Engineering Capabilities
Civil Infrastructure Structures
Design and documentation for water, sewer, and stormwater infrastructure including headwalls, wingwalls, box culverts, pump station structures, pits, manholes, thrust blocks and underground detention systems.
Retaining Walls & Earth Retention Systems
Design of gravity walls, cantilever walls, MSE wall systems, sheet pile design, and temporary shoring for road corridors, subdivisions, and civil works. We coordinate with geotechnical investigations and civil drainage requirements.
Foundations & Ground Support
Foundation design for civil structures, bearing capacity verification, settlement assessment, and foundation remediation. We work directly with geotechnical consultants and civil design teams to coordinate site constraints.
Buildings
Structural design for operations centres, portal frame sheds, industrial sheds, maintenance facilities, amenities buildings, and covered storage associated with civil infrastructure projects. We understand the integration requirements between building structures and civil site works.
Temporary Works & Construction Engineering
Trench shoring systems, formwork design, temporary access structures, crane pad design, and construction loading analysis. We provide practical solutions that align with contractor methodologies.
Structural Assessments & Peer Review
Condition assessments of existing infrastructure, load rating analysis, structural peer review for authority submissions, Structural Engineering Assessments (SEAs) and remediation feasibility studies.
Our Delivery Model
Feasibility & Concept
We participate in site assessments and early design workshops to identify structural requirements, constructability constraints, and cost implications before designs are fixed.
Detailed Design
Structural and civil designs are developed concurrently with regular coordination reviews. We use shared models and drawings to minimise clashes and ensure documentation consistency.
Authority Approvals
We understand local authority structural requirements and work with the civil team to prepare coordinated approval packages that address both civil and structural aspects of submissions.
Tender & Construction
We provide responsive RFI management, shop drawing reviews and site observations coordinated with civil construction milestones. Design clarifications are resolved internally without external consultant delays.
The AT&L Difference
Integrated Civil-Structural Delivery
AT&L delivers structural engineering within an established civil practice. Structural and civil design develop together from the start, not as separate consultants after key decisions. Our engineers understand infrastructure constraints, authority requirements, and construction realities for WSC and transport projects.
Civil Infrastructure Specialisation
Our structural capability focuses on civil infrastructure. We understand requirements from water authorities, road authorities, and councils. This includes Sydney Water certification, TfNSW impact assessments, and retaining wall approvals. Our knowledge comes from consistent delivery in these sectors.
Local Authority Knowledge
We have strong approval experience with councils and state authorities involved in civil infrastructure. Our team understands regional submission requirements, including calculation methods, documentation standards, and inspection protocols. This helps reduce approval delays.
Practical Construction Focus
AT&L designs for constructability, not just compliance. Our engineers consider contractor feedback, formwork costs, and buildability during design. Site experience informs our details, helping builders price and construct efficiently.
Proven Delivery
AT&L has delivered 1,400+ civil infrastructure projects with integrated structural components over 17+ years. Many contractors and developers engage us repeatedly because they value coordinated design delivery.
