Tutorial Presto 8.8: Mastering Construction Cost Estimation Presto 8.8 remains a foundational version of one of the most widely used software tools in the construction industry for budgeting, measurements, and project management. This version is particularly valued for its stability in handling complex cost estimates and its ability to integrate with CAD/BIM workflows.
This tutorial provides a step-by-step guide to navigating the core functionalities of Presto 8.8, from creating a new budget to generating final reports. 1. Getting Started: Creating Your First Budget
To begin a project in Presto 8.8, you must establish the basic structure of your construction budget.
Create a New File: Open the software and select "File" > "New." Enter the project code and a descriptive summary.
The Workspace: Familiarize yourself with the interface. The main window typically displays the budget hierarchy, including Chapters and Items (Partidas).
Chapters and Items: Organize your project by creating "Chapters" (e.g., Earthworks, Foundation) and adding individual "Items" (Partidas) under each. You can manually enter these or copy/paste from Excel to save time. 2. Managing Prices and Cost Breakdowns
Presto 8.8 excel at managing "unit prices" and "cost breakdowns" (descompuestos), allowing for precise financial control.
Direct Entry: You can manually type in prices for specific materials or labor.
Price Databases: Use existing price databases (bases de precios) to drag and drop standard items into your project.
Cost Breakdowns (Descompuestos): For a complex item like "Reinforced Concrete," you can create a breakdown of its components—cement, gravel, steel, and labor—to see how the final unit price is calculated. 3. Taking Measurements (Mediciones)
Accurate measurements are the backbone of a reliable budget. Presto 8.8 offers several ways to input this data:
Manual Input: Enter dimensions (length, width, height) directly into the "Mediciones" tab for each item.
CAD Integration: Presto 8.8 allows you to import measurements directly from AutoCAD (DWG format), reducing manual entry errors.
Detailed Rows: Use separate rows for different areas of the construction (e.g., "North Wall," "South Wall") to keep your measurements organized and easy to verify. 4. Customizing Reports and Documentation
Once your budget is complete, you must generate professional documentation for clients or site managers.
Predefined Reports: Presto includes standard templates for "Budget Summaries" and "Detailed Item Lists". tutorial presto 8.8
Personalizing Reports: Use the Customization Module to adapt report headers, logos, and data columns to match your company's branding.
Exporting Data: While Presto is more powerful than a spreadsheet, you can export your final data back to Excel if needed for further analysis. 5. Advanced Features: Planning and Certification
For long-term projects, Presto 8.8 supports the entire construction lifecycle:
Planning: Convert your budget into a schedule by defining tasks and durations, creating a visual link between time and cost.
Certifications: As work progresses, use the "Certificaciones" module to track what has been built versus what was planned, ensuring accurate monthly billing to the client.
You can find in-depth video tutorials and professional courses at the Academia Ingnova or explore the Manual de Presto from RIB Spain for comprehensive technical documentation.
"Presto 8.8" typically refers to an older but foundational version of the Presto construction software, a widely used tool in Spanish-speaking countries for managing project budgets, estimates, and construction tracking. Unlike the "Presto" SQL engine, this software is specifically designed for architects and engineers.
Here is a helpful tutorial summary to get you started with Presto 8.8, based on its core workflow for creating a construction budget. 1. Initial Project Setup
To start a project, you must first define the general parameters of your work:
Create New Project: Use the File > New menu to name your project and set the storage path.
Work Properties: Access the Properties window to set the language and currency. For example, you might select a specific price database (like a regional construction index) as your baseline.
Financial Percentages: In the Percentages tab, define your project's overhead costs. Typical values for Presto users include: Overhead (Gastos Generales): Often set around 13–20%.
Industrial Profit (Beneficio Industrial): Usually around 6–10%. Tax/IVA: Set the applicable tax rate for your region. 2. Building the Project Structure
Presto uses a hierarchical system of chapters and work items (partidas):
Chapters: These represent major stages like "Earthworks" or "Foundations." Simply enter a code and a name in the main budget window. Tutorial Presto 8
Work Items (Partidas): Within each chapter, add specific tasks. For example, "Excavation" might be a partida. You must manually enter the quantity needed for each item.
Sub-items (Descomposición): Double-click a work item to break it down into resources: Materials, Labor (manpower), and Machinery. 3. Measurements and Quantities
The "Measurements" tab is where you detail exactly how you arrived at a total quantity:
Line Measurements: You can list specific dimensions (Length x Width x Height) for different areas of the building.
Copying Data: You can drag and drop measurement lines between two open projects. Dragging a whole item copies its measurements, while copying just the code only transfers the description and price breakdown. 4. Generating Reports
Once your budget is complete, you can export it to professional formats:
Report Configuration: Go to the reports menu to choose between "Project Coding" (standard) or "Decimal Coding".
Filters: You can choose to hide items with zero quantity or price to keep the final document clean.
Exports: Most users export the final "Presupuesto y Mediciones" to PDF or Excel for client submission. Learning Resources
Because Presto 8.8 is a legacy version, video-based learning is often the most effective:
YouTube Playlists: Comprehensive tutorials like this Presto 8.8 Playlist walk through every menu and function.
Practice with Demos: You can often find demonstration versions at sites like RI Software to practice these steps without a full license. Presto - Topic 1 Start
This tutorial covers the essential features and navigation of Presto 8.8, a specialized software for construction budgeting and project management. 1. Navigation and Interface Views
Presto 8.8 allows users to navigate budgets through several specialized views to manage complexity:
Concept View: Focuses on individual items and their detailed properties. Part 5: Troubleshooting Common Issues Since Presto 8
Tree View: Displays the hierarchical structure of the project.
Chapters Only: A high-level view showing only the major sections of the budget.
Deployable Chapters: Allows users to expand specific chapters to view underlying work items (partidas) while keeping others collapsed. 2. Work Environment Configuration
You can tailor the interface to your workflow via the Options menu: Visuals: Customize workspace colors for better readability. Safety: Enable Autosave to prevent data loss.

The core functionality involves building a budget using standardized fields. Key data points for each item include:
Code & Nature: Unique identification and classification (e.g., material, labor).
Unit of Measure & Quantity: Defines how the work is quantified (e.g., m2m squared , kg).
Unit Price & Amount: The cost per unit and the total calculated value for the item. 4. Critical Concept Management
Precision is vital in Presto 8.8 because the software uses a relational structure:
Consistency: Changing a price or quantity in one view automatically updates the final budget total.
Error Prevention: Ensure "Chapters" and "Partidas" are correctly nested to maintain structural integrity.
