Part Four: Phase Two – Detailed and Technical Design August 16, 2025, Thursday
Following the approval of conceptual designs in Phase One, the project enters a stage where everything becomes precise and implementable. Phase Two of architectural design is the stage in which the project's drawings, details, technical specifications, and implementation information are prepared and compiled.
What is the goal of Phase Two?
In this phase, the main goal is to produce documents and drawings that are not only necessary for obtaining the required legal permits but also enable the contractor to properly execute the project.
Main Outputs of Phase Two
Detailed architectural drawings (plans, elevations, sections) Structural drawings (foundation, columns, beams, framework) Mechanical and electrical system drawings Implementation details and sections Technical specifications and materials booklet
Main Stages of Phase Two
Detailed Architectural Drawings Includes precise details of walls, doors, windows, ceilings, and floors Complete dimensioning for implementation Specifying materials, colors, and finishes
Structural Design Analysis of applied loads and selection of appropriate structural system Design of foundation, framework, and load-bearing elements Specifying the type and dimensions of beams, columns, and connections
System Design Mechanical Systems: Cooling, heating, ventilation, water and sewage piping systems Electrical Systems: Lighting, outlets, electrical panels, fire alarm and communication systems Attention to the coordination of systems with architecture and structure
Technical Documentation Preparation of technical booklets including material specifications, implementation methods, standards, and regulations Initial estimate of materials required for the implementation phase
Preparation for Obtaining Permits Complete alignment of drawings with the regulations of the municipality and the engineering regulatory organization Submission of necessary documents for obtaining a building permit
Summary
Phase Two is the technical heart of the project. The more accuracy is invested in this phase, the construction stages will be implemented with less error, more controlled costs, and higher quality. This phase is the connection point between design and implementation.
