Reports & Calculations

Our expert team delivers detailed structural reports and precise calculations tailored to your project’s specific needs. We ensure structural integrity and full regulatory compliance for residential, commercial, and government developments nationwide.

Structural Drawings
Drafting Services

We provide high-quality, BIM-compatible structural drawings that bridge the gap between design and construction. Our detailed plans ensure clear communication for contractors and a smooth building consent process.

Design Producer Statements
(PS1)

We provide formal Design Producer Statements (PS1) to confirm that our structural designs meet the rigorous requirements of the New Zealand Building Code. This essential documentation gives councils and building consent authorities the confidence to approve your project.

Peer Reviews
(PS2)

We provide independent regulatory peer reviews to verify that structural designs comply with New Zealand Building Codes. Our objective analysis offers an extra layer of assurance for complex projects, ensuring safety and facilitating the issuance of a PS2 for council approval.

Construction Monitoring Services
Producer Statements (PS4)

We provide professional site inspections to ensure construction aligns perfectly with the approved structural designs. Upon successful completion, we issue the Producer Statement (PS4) required by the council for your Code Compliance Certificate (CCC).

Initial & Detailed Seismic Assessments
(ISA & DSA)

We provide expert seismic evaluations to determine the earthquake resilience of your building. Our team conducts Initial Seismic Assessments (ISA) for high-level risk identification and Detailed Seismic Assessments (DSA) for a precise, code-compliant understanding of structural performance and %NBS ratings.

Structural Investigations
Condition Assessments

We perform detailed forensic investigations and condition assessments to evaluate the health of existing structures. Our engineers identify defects, material degradation, or structural weaknesses, providing clear data to inform maintenance, safety upgrades, or property transactions.

Structural Remediation
Strengthening Designs

We specialize in extending the life of existing structures through innovative remediation and strengthening solutions. Whether addressing material fatigue, seismic upgrades, or change-of-use requirements, our designs restore structural integrity and ensure long-term durability.
