This definitive collection of AI prompts represents the gold standard in the technical and financial management of civil engineering projects. Meticulously designed by project control experts, it allows you to automate critical valuation analysis, optimize operational profitability and guarantee regulatory compliance at each stage of the work, from the initial budget to final closure. By integrating these prompts into their workflow, professionals in the construction sector will obtain unprecedented precision in calculating readjustments, controlling inputs, and managing additional items. It is the indispensable strategic tool for resident engineers, supervisors and project managers seeking to maximize administrative efficiency and minimize the risks of legal disputes in final settlements.
He acts as a Senior Consultant Specialist in Construction Costs and Budgets with extensive experience in preparing Valuations and Analysis of Unit Costs (ACU) under civil construction regulations. Your primary objective is to carry out an exhaustive technical and financial analysis on how the inclusion of new salary variables, specifically the [Tipo_de_Bonificacion] (for example: bonus for height, for contact with water, risk bonus, or agreed productivity incentives), alters the cost structure of the critical items of the project: [Lista_de_Partidas_Especificas]. It begins by breaking down the current composition of the labor cost for the project located in [Ubicacion_Geografica], considering the current scale for operator, officer and laborer according to [Convenio_Colectivo_Referencia]. You must accurately calculate the new Man-Hour Cost (HH) by integrating all social laws, mandatory insurance and, in isolation, the percentage and nominal impact generated by the requested bonus on the direct cost of each selected item. It is vital that you identify if this extra cost is absorbable by general expenses or if it requires an update of the meter and unit cost spreadsheet for the next valuation. Subsequently, it develops a proposal for technical performance optimization. Given the increase in labor costs due to these bonuses, propose strategic adjustments in the configuration of the [Cuadrillas_Tipo]. Analyzes whether it is feasible to increase daily performance by incorporating [Equipo_o_Maquinaria_Complementaria] or whether input logistics on the work front must be restructured to minimize downtime. The objective is to balance the increase in unit cost with greater operational efficiency that protects the contractor's profit margin defined in the [Tipo_de_Contrato] type contract. Finally, generate a detailed comparative report that includes a 'Cost Sensitivity Analysis' table. This table shows 'Base ACU' versus 'Bonus Impact ACU', detailing the percentage change in the total direct cost of the item. Includes a section of legal and technical recommendations to support this increase before the Work Supervision or the Entity, based on the [Pais_o_Region] regulations and the price readjustment mechanisms (Polynomial Formulas) if applicable for this specific situation. If any key information needed to fill the bracketed fields is missing, ask me the necessary questions before answering.

Acts as a Senior Engineer specializing in Project Control and Cost Management (PMP/CCP) with extensive experience in optimizing Unit Cost Analysis (CUA) for complex infrastructure projects. Your mission is to execute an exhaustive analysis and technical reengineering of the theoretical returns assigned to the budget item of [Name of the Specific Item], with the purpose of adjusting the work valuations to the operational reality of the project [Project Name and Geographic Location]. To begin, you must process the base data of the technical file: the current theoretical performance of [Performance in the File, e.g.: 15m3/day], the current composition of the crew [Personnel Description, e.g.: 1 Operator + 1 Officer + 2 Labourers] and the agreed hourly cost of labor. Integrate into your analysis external disruptive factors such as [Environmental Factors, e.g.: Altitude 4000 meters above sea level or Tropical Climate] and the logistical limitations of the supply of critical inputs such as [Main Inputs, e.g.: Ready-Mixed Concrete or Corrugated Steel]. It applies an optimization methodology based on the measurement of productivity (Lean Construction). Identifies bottlenecks through the breakdown of Productive Work (TP), Contributory Work (TC) and Non-Contributory Work (TNC). Propose alternative crew balancing scenarios and suggest the incorporation of tools or minor machinery [Type of Equipment, e.g.: 11p3 Mixer or Concrete Vibrator] that allow raising real performance over theoretical performance, optimizing the use of resources and reducing execution times in the valued schedule. The final result must be presented as a Technical Optimization Report that contains: 1. Comparative table of performances (Theoretical vs. Optimized), 2. Analysis of the economic impact on the Direct Unit Cost, 3. Sensitivity graph that shows the variation of the profit margin according to the increase in productivity, and 4. Detailed action plan for field supervision to guarantee that the new performance is maintained during the period of [Match Execution Period]. If any key information needed to fill the bracketed fields is missing, ask me the necessary questions before answering. Important: do not invent citations, case numbers, rulings, studies, or references. If you cannot verify them against real sources (web search or documents I provide), say so clearly, base the analysis on general criteria, and point out which data I should verify in official sources.
Acts as a Senior Cost and Budget Engineer with a specialty in infrastructure and mining. Your mission is to design a 'Rent for rented equipment' of high technical precision, specifically designed to be integrated into the Unit Cost Analysis (ACU) and facilitate the management of valuations in the [Project Name] project. The tariff must contemplate a matrix structure that separates fixed costs from variable costs to allow dynamic adjustments to market fluctuations during the [Evaluation Period] period. Develop a detailed technical table for the fleet equipment: [Machinery List: e.g. 336 Excavator, 15m3 Dump Truck, Motor Grader]. For each item, you must calculate and justify the Total Hourly Cost (USD/HM or Local Currency), obligatorily breaking down the following components: 1) Cost of Possession (Depreciation, interest, insurance) if applicable for sublease, 2) Cost of Operation (Fuel calculated by gallons/hour according to workload, lubricants, filters, tires/tracks, and preventive/corrective maintenance), and 3) Cost of specialized Operator including social benefits according to the regime of [Geographic Location/Country]. Optimize the technical performance of each piece of equipment based on the specific conditions of [Type of Soil or Height above sea level]. You must establish a 'Standard Yield' vs 'Expected Actual Yield' column for [Specific Game: e.g. Earthworks, Mass excavation]. Use this data to propose the configuration of optimal 'Type Crews', calculating the contribution coefficient of each team per unit of measurement (m3, m2, ml). Be sure to include calculation logic for the efficiency factor (effective minutes per hour) and material swell factor. Finally, it generates a technical clause for the control of valuations that defines the treatment of 'Guaranteed Minimum Hours', 'Stand-by Hours' (Equipment stopped for reasons not attributable to the contractor) and 'Maintenance Hours'. The objective is for this tariff to serve as the main annex in the negotiation with suppliers and as a source of truth for the calculation of the operational profitability of the project in the currency [Local Currency]. If any key information needed to fill the bracketed fields is missing, ask me the necessary questions before answering.

Delivers what it promises. The prompts are useful and practical. I recommend it.
It's fine, nothing more. Some prompts are great and others more generic. Could be better but useful.
I was impressed by the quality. They work just as well in ChatGPT and Claude. I'll buy again without hesitation.
Best purchase I made this month. They saved me hours of work in the first week. An investment that pays for itself.
Best purchase I made this month. The quality of the answers I get improved a lot. Totally recommend them.
It's fine, nothing more. I had to tweak them quite a bit for my case. Works if you customize it.
Exceeded my expectations. They saved me hours of work in the first week. One hundred percent recommended.
