Diferences between a Basic Project and a Execution Project

Written By Francisco Javier Muñoz Fuentes

In the world of architecture, precision and planning are essential to ensure a project runs smoothly. Two key stages in the architectural process are the Basic Project and the Execution Project. Although they are often mentioned together, each has specific objectives and distinct roles in the development of a space. If you are considering building, renovating, or designing a space, understanding these differences is crucial. Here’s everything you need to know.

1. Definition and Objective of the Basic Project

The Basic Project is the first phase of the architectural process. Its primary goal is to establish the foundations of the project, providing a general overview of how the design will be carried out. This project includes key decisions on layout, forms, volumes, materials, and more general aspects of the design.

Main Objective: Define the essential elements of the project, such as layout, volumes, functionality, and key space characteristics.
Phases of the Basic Project:
- Definition of spaces and their functionality.
- Selection of materials and general construction systems.
- Feasibility study, both technical and economic.
- Preparation of preliminary budgets and timelines.
Importance: It provides a clear idea of how the final design will look and serves as the starting point for decision-making.

2. Definition and Objective of the Execution Project

The Execution Project is the next step after the Basic Project. Here, all the technical details necessary to carry out the design are concretized. This project focuses on precision and detail, becoming the guiding document that contractors and professionals will follow to materialize the design.

Main Objective: Specify with accuracy how each aspect of the project will be executed, from design to construction.
Phases of the Execution Project:
- Planning and detailing of installations (electrical, plumbing, etc.).
- Definition of exact materials, finishes, and construction details.
- Precise calculation of quantities and budgets.
- Breakdown of tasks necessary for executing each phase.
Importance: Ensures the project is built exactly as designed, avoiding deviations that may result in cost overruns or errors.

3. Key Differences Between Basic and Execution Projects

Level of Detail:
- Basic Project: Provides a general overview, with essential details but without in-depth technical information.
- Execution Project: Offers a high level of detail, specifying all technical and construction aspects.
Objective:
- Basic Project: Defines the concept and general idea of the project.
- Execution Project: Focuses on how to materialize that idea with precision.
Format:
- Basic Project: More conceptual documentation, with schematic plans and general details.
- Execution Project: More technical, detailed, and concrete documentation.
Participants:
- Basic Project: Generally carried out by the architect, with support from other professionals like engineers.
- Execution Project: Requires more coordination between the architect, engineers, contractors, and suppliers.

4. Products Generated:

Basic Project:

Conceptual and preliminary plans.

Space layout plans (general floor plans and sections).

Basic elevations and perspectives.

Design of facades and key architectural elements.

General location of installations (electrical, sanitary, etc.).

Descriptive memory

Explaining design objectives and solutions.

Definition of materials and general finishes.

Preliminary budget and project feasibility analysis.

Regulatory documentation

Ensuring compliance with urban and local regulations.

Execution Project:

Detailed technical plans.
Detailed floor plans, sections, and elevations.
Installation plans (electrical, plumbing, mechanical).
Construction details (scales, joints, finishes, materials).
Technical specifications.
Material lists, products, and construction techniques.
Detailed budget breakdown by items.
Technical and regulatory requirements (insulation systems, quality standards, etc.).
Permitting documentation.
Structural calculations.
Installation calculation memory (electrical, plumbing, etc.).
Construction timeline and schedule.
Plans for equipment and material placement on site.
Administrative and budgeting documentation.
Layout plans for equipment and materials on-site
Administrative and budgetary documentation.
Adjusted budgets with precise cost breakdowns.
Reports, measurement plans, and quality control documentation.

5. Benefits of Having Both Stages Clearly Defined

Having a solid Basic Project ensures that initial decisions are the right ones, avoiding potential long-term errors or deviations. On the other hand, a well-developed Execution Project ensures precise and efficient construction, ensuring the design is carried out as planned.

By combining both phases, a thorough planning process is achieved, reducing risks, optimizing time, and saving on the budget.
