Services
Structural Engineering
Our structural engineering services provide comprehensive assessments and design solutions for new construction and existing buildings. We specialize in identifying structural deficiencies, developing repair plans, and ensuring compliance with current building codes. Our engineers deliver precise calculations and detailed documentation to support safe, durable construction projects across commercial, institutional, and residential sectors.
Building Envelope Evaluation
We conduct thorough building envelope evaluations to identify moisture intrusion, material deterioration, and performance issues. Our forensic investigations include field testing, material analysis, and condition mapping to develop targeted remediation strategies. This service helps property owners extend asset lifespan while maintaining energy efficiency and weather resistance for facades, roofs, and waterproofing systems.
Construction Management
Our construction management services cover all project phases from pre-design to final inspection. We provide quality assurance, schedule coordination, and contractor oversight to ensure projects meet technical specifications and budget requirements. Our team manages documentation, change orders, and compliance verification while maintaining open communication between all stakeholders throughout the construction process.
Waterproofing Design
We design advanced waterproofing systems for new construction and remediate existing waterproofing failures. Our solutions address roof membranes, plaza decks, foundation barriers, and facade flashings using industry-leading materials and techniques. We conduct moisture surveys, develop repair specifications, and implement testing protocols to guarantee long-term protection against water damage in both above-grade and below-grade applications.
Restoration Services
Our restoration services focus on repairing and rehabilitating deteriorated building components including concrete structures, masonry facades, and parking garages. We develop customized repair plans based on forensic analysis, oversee contractor execution, and implement quality control measures. These services restore structural integrity while maintaining aesthetic consistency and functional performance for commercial properties of all ages.
