Our Design & Construction Process
At Gren-Mac Construction Inc., we believe that a well-structured process ensures smooth project execution,
high-quality outcomes, and client satisfaction. Our approach is divided into carefully planned phases to turn
your vision into reality.
1
Early Discussion & Briefing
Every project begins with a thorough consultation. We meet with you to understand your needs, goals, budget, and expectations. This phase lays the foundation for a successful project by identifying key priorities, potential challenges, and initial design preferences.
2
Conceptual Design Phase
Once we understand your vision, we begin conceptualizing ideas.
This stage includes:
​
• Preliminary sketches and layouts
• Feasibility studies
• Initial cost estimations
• Discussions on materials and
sustainability
3
Schematic Design Phase
We refine the initial concept into a more structured schematic design.
This involves:
​
• Detailed floor plans and elevations
• 3D visualizations (if required)
• Material selection guidance
• Compliance checks with local
building codes
4
Design Development Phase
In this phase, we take the schematic design further by adding technical details and refining aesthetics.
This stage includes:
• Structural, mechanical, and
electrical considerations
• Selection of construction
materials
• Coordination with engineers and
specialists
5
Professional Coordination
To ensure seamless execution, we collaborate with industry professionals such as architects, engineers, and consultants.
This ensures:
• Adherence to safety regulations
• Efficiency in construction
execution
• Alignment of all design elements
6
Working Drawing Phase
This phase involves finalizing the detailed construction drawings, including:
​
• Architectural plans
• Structural layouts
• Electrical and plumbing
schematics
• Specifications for finishes and
fittings
Construction Phase
Once construction begins, we focus on two key aspects to ensure a smooth and efficient building process:
1
Documentation
We prepare comprehensive construction documents that include:
​
• Detailed floor plans, elevations, sections, and views.
• Specifications for building materials, along with recommendations for trusted suppliers. To maintain high-quality standards, we conduct inspections at the beginning, middle, and final stages of construction.
Our quality control process covers:
​
• Building Structure & Dimensions – Ensuring accurate elevation, section details, floor-to-floor heights, and precise openings for windows, doors, and ventilation.
• Design & Finishing Details – Confirming exterior wall colors, façade elements, parapet walls, railings, and overall aesthetics.
• Layout & Room Dimensions – Verifying that the floor plan aligns with the site plan.
• Material Specifications – Checking the quality and suitability of materials for floors, walls, ceilings, roofs, sanitation, and landscaping.
2
Administration
• Regular On-Site Inspections – Monitoring progress to
ensure construction follows the design and stays on
schedule.
​
• Project Coordination – Assisting contractors in
maintaining an organized and timely workflow.
​
• Final Inspection – Conducting a thorough review at the final stage to confirm that the completed structure aligns with the approved construction drawings and meets our quality standards.
​
This structured approach guarantees that every project is built with precision, efficiency, and the highest level of craftsmanship.
