Architectural Programming
We analyze spatial requirements and functional needs to create optimized layouts. Our team evaluates mechanical systems, parking demands, and construction types while aligning with client budgets. This foundational phase ensures all design elements meet project goals and regulatory standards.
Site Selection
Our experts assess potential sites for zoning compliance, environmental factors, and infrastructure access. We prepare schematic layouts and review geological reports to identify optimal building configurations that balance cost efficiency with long-term usability for commercial and residential developments.
Schematic Design
We develop floor plans, elevations, and 3D renderings to visualize project concepts. This phase includes material selection, structural proposals, and preliminary cost estimates to establish clear design direction before advancing to detailed documentation.
Construction Documents
We produce comprehensive technical drawings and specifications for permitting and construction. Our documents coordinate structural, mechanical, and electrical systems while ensuring compliance with building codes and municipal requirements through detailed engineering collaboration.
Construction Administration
We provide on-site monitoring and documentation during construction phases. Our team processes pay applications, issues clarifications, and maintains quality control through regular progress reports and punch list coordination to ensure final deliverables match approved designs.
