Marco Sumari

Marco Sumari is an independent software publisher operating through the website ingepresupuestos.com, offering a focused catalog centered on a single product for the construction industry. The publisher's flagship application, IngePresupuestos, is free software designed for preparing construction project budgets, addressing the needs of engineers, architects, contractors, and project estimators who require structured cost planning tools. The software organizes budget preparation around the ACU (Análisis de Costo Unitario, or unit cost analysis) methodology, which is the standard approach in Spanish-speaking construction markets for breaking down the cost of each work item into labor, materials, equipment, and overhead components. In addition to budget creation, IngePresupuestos includes a valued Gantt chart, allowing users to link project scheduling with financial data so that the timeline of activities corresponds directly to the planned disbursement of funds over the course of a project. The product also generates thirteen professional reports, supporting the documentation and presentation requirements typical of construction bidding, client proposals, and project control. Typical use cases include preparing cost estimates for building projects, producing formal budget documents for tenders, planning work schedules with associated cash flow projections, and delivering standardized reports to clients or supervisors. Because the software is distributed as freeware, it provides an accessible alternative to commercial estimating suites for small construction firms, independent professionals, and students in civil engineering or architecture. The publisher's offering is representative of a niche software category: vertical-market tools that combine cost estimation, unit price analysis, and project scheduling into a single workflow tailored to the conventions of the construction sector in Latin America and other Spanish-speaking regions.
