The construction industry, being one of the most important sectors of a country's economy, must constantly adapt to market changes. Not only technological innovation and the use of less environmentally harmful resources are important for this industry. It also requires better work methods, supervision and control to guarantee the profitability of its projects. The planning and budgeting of the work, the negotiation of the cost of materials, the supervision of labour and compliance with established deadlines are some of the key factors to ensure the expected quality and profitability.
