Childs Engineering brings over 55 years of experience dedicated solely to providing waterfront structural engineering services. Our expertise serves both public and private sector clients with a comprehensive range of services tailored to the unique challenges of waterfront infrastructure.
This work encompasses tasks such as topside and underwater inspections, structural and geotechnical analysis, surveying, permitting, and preparation of plans and specifications.
From initial condition assessments to the design of repairs or new structures to construction oversight, Childs Engineering delivers end-to-end solutions, to ensure quality and longevity in every project.
Uniquely, our engineers are also cross-trained as ADCI certified commercial divers.

This integrated approach ensures first-hand knowledge, deeper project insight, and more accurate assessments, reports, and designs.
