Three common mistakes in construction – and how to avoid them from the outset
Construction is a complex process, regardless of the size or type of project. Whether it is a house, a commercial building or a larger-scale project, there are recurring mistakes that can compromise deadlines, budgets and final quality. In construction in the Algarve, where many projects involve significant investment and high expectations, preventing these mistakes becomes even more important.
In this article, we highlight three common mistakes in construction and explain how a structured approach, such as that adopted by J.A. Duarte & Filho, contributes to more efficient, predictable and controlled execution.
Starting the work without clearly defined specifications
One of the most common mistakes in construction in the Algarve is to start work without a complete and properly validated set of specifications. This document is essential, as it precisely defines the materials, construction methods, responsibilities, deadlines and execution criteria.
Why is this a problem?
The absence of clear specifications opens the door to:
- Different interpretations among stakeholders
- Difficulty in managing costs
- Constant changes during construction
- Conflicts between the client, designers and contractor
Without this technical reference, the project loses predictability and control from day one.
How to avoid it
At J.A. Duarte & Filho, the technical analysis of the project and documentation is carried out before the start of the work, ensuring that all decisions are defined from the outset. This planning allows us to align expectations, reduce unforeseen events and ensure execution that is consistent with the approved project.
Excessive subcontracting and dependence on third parties
Another common mistake in construction is excessive fragmentation of work through multiple subcontracting. Although this is common practice in the sector, when it is not well managed it can compromise coordination, quality and deadlines.
Why is this a problem?
- Excessive subcontracting can result in:
- Lack of direct control over the work
- Difficulty in coordination between teams
- Delays due to dependence on third parties
- Less uniformity in execution standards
Each additional stakeholder increases the complexity of construction management.
How to avoid it
J.A. Duarte & Filho stands out for carrying out most of the work internally, with its own teams, machinery and appropriate technical resources. This approach allows for greater control over the work, better coordination between phases and a faster response to technical challenges, which is especially relevant in construction in the Algarve, where deadlines and logistics are critical factors.
Constant changes to the project and the emergence of extra work
Frequent changes to the initial design are another factor that causes significant time and budget overruns. Although some changes are inevitable, a lack of initial definition often leads to unforeseen extra work.
Why is this a problem?
- Successive changes imply:
- Constant replanning
- Additional costs
- Interruptions in the normal sequence of work
- Difficulty in meeting agreed deadlines
Each change affects the overall balance of the project.
How to avoid it
Rigorous planning from the initial phase, combined with an experienced technical reading of the project, significantly reduces the need for changes during construction. At J.A. Duarte & Filho, our accumulated experience in civil construction in the Algarve allows us to anticipate incompatibilities, propose tailored technical solutions and minimise deviations during execution.
Planning, control and experience make the difference
Avoiding these three mistakes – lack of specifications, excessive subcontracting and constant changes to the project – is essential for the success of any construction project. Successful construction always begins before the first sod is turned, with planning, clear definitions and skilled teams.
At J.A. Duarte & Filho, each project is approached with technical rigour, control of resources and close monitoring, essential factors for ensuring quality, predictability and confidence in construction projects in the Algarve.
Investing in a structured approach does not eliminate all challenges, but it significantly reduces risks and ensures more efficient and sustainable execution in the long term.
