Building science & envelope engineering

Drawing & Submittal Review

Review architectural drawings and construction details from a building science and building envelope perspective to verify compliance with applicable building codes, project specifications, industry standards, and best practices. We assess the continuity and performance of building envelope systems, identify potential deficiencies or constructability concerns, and provide practical recommendations to improve durability, moisture control, thermal performance, air tightness, and long-term building performance before construction begins.

Field Reviews & Quality Assurance

Conduct regular site inspections throughout construction to monitor the installation and quality of critical building envelope components and verify compliance with contract documents, approved shop drawings, building code, manufacturer requirements, and applicable standards.

Building Condition Assessments

NEX provides comprehensive Building Condition Assessments (BCA) to help building owners, property managers, and stakeholders understand the current performance, condition, and future maintenance needs of their properties. Assessments include detailed reviews of building envelope systems, roofing, waterproofing, exterior walls, windows, common areas, and other critical components to identify deficiencies, potential risks, and required maintenance or repair measures. Through visual inspections, technical evaluations, and condition analysis, we deliver practical recommendations that support informed decision-making, prioritize repair strategies, and help extend the service life and long-term value of building assets.

Technical Meetings & Construction Support

Participate in meetings with owners, developers, architects, contractors, consultants, and project teams to review technical issues, discuss construction progress, evaluate building envelope concerns, recommend practical solutions, and assist in resolving site-related challenges while supporting successful project delivery.
