proHNS provides a wide range of engineering, technical, and administrative services. With our extensive network of skilled team members residing throughout Alaska, we can usually contribute local staff to a project that might otherwise lack community or regional insight. Check out our Project Portfolio for some examples of how we’ve put our skills to use.
Our Civil Engineers and support staff provide exceptional water resources engineering, transportation engineering, slope stabilization design, Americans with Disabilities Act (ADA) accessibility design, technical analysis and reporting, conceptual design and planning, construction cost estimating, specification writing, preparation of contract documents, and project delivery services.
Construction Administration and Inspection
Our Project Engineers, Office Engineers, and Engineering Technicians can handle all of your CA/I needs, including Owner representation, on-site inspection and reporting, stakeholder coordination and communication, constructability reviews, project schedule analysis, cost estimating and tracking, review of shop drawings and submittals, issuance of progress payments, drafting of change orders, responding to requests for information or design variance proposals, recordkeeping, and project closeout.
