Resumen: El presente informe de competencia profesional, se sustenta en el desarrollo de una herramienta de trabajo que brinda una alternativa de solución para la obtención de los costos incurridos por el alquiler del equipo de encofrado en obras de gran envergadura.
Esta herramienta tiene como objetivo homogenizar el proceso de obtención de costos sin distinguir la empresa proveedora del equipo de encofrado, esto es posible debido a que todas las empresas dedicadas al alquiler del equipo de encofrado, basan su operación en una lista de precios inicial, es decir una lista sin descuento comercial y la entrega de guías de remisión para contabilizar todas las unidades alquiladas que forman parte del sistema de encofrado elegido por obra.
La herramienta de control de valorizaciones de encofrado, se ha aplicado a lo largo de todo el plazo de la fase de estructuras en la obra “Mall Aventura Plaza – Santa Anita”, cuya ejecución se llevó a cabo desde el 01 de Setiembre del 2011 hasta el 31 de mayo del 2012.
La herramienta asumió en su control a cinco empresas dedicadas al alquiler de equipo de encofrados y andamios, los costos incurridos por cada empresa han sido contabilizados semanalmente durante 39 semanas, llevando un adecuado seguimiento a las valorizaciones para evitar desviaciones negativas en lo presupuestado.
La herramienta de control de valorizaciones se ha desarrollado íntegramente en el programa Excel de Microsoft, este programa ha sido el más adecuado debido a su versatilidad de cara a la correcta supervisión de las partidas de control definidas por la obra.
Es importante mencionar que dicho control tiene las siguientes consideraciones:
1. El planeamiento de obra debe respetarse en su gran mayoría, a lo largo del tiempo que dure la obra, ya que el control no es posible si no se respeta este planeamiento inicial.
2. La canalización de información de los ingresos de materiales a obra, deben ser responsabilidad de oficina técnica, respaldada por la jefatura de almacén.
3. Debe existir una sola persona de obra encargada de la comunicación hacia las empresas proveedoras del equipo de encofrado, y debe ser la única persona quien puede dar el visto bueno para el ingreso o devolución de materiales.
Con estas consideraciones se diagrama el programa a la necesidad de obra, en las partidas de control designadas y con las empresas proveedoras elegidas previamente mediante un cuadro comparativo. Con ello se empieza el control de valorizaciones cada semana, siendo actualizado toda vez que existan ingresos o devoluciones de unidades del equipo de encofrado.
De esta manera se llevó a cabo un adecuado control de valorizaciones en la obra “Mall Aventura Plaza – Santa Anita”, obra considerada de gran envergadura en el rubro de centros comerciales.
This competence report is based on the development of a work tool that provides an alternative solution to obtain the costs incurred by the rent of the formwork equipment in large-scale works. This tool aims to homogenize the process of obtaining costs without distinguishing the supplier company from the formwork equipment, this is possible because all companies engaged in the rental of formwork equipment, base their operation on an initial price list, is say a list without commercial discount and the delivery of reference guides to account for all leased units that are part of the formwork system chosen by work. The formwork control tool has been applied throughout the entire phase of structures in the work “Mall Aventura Plaza - Santa Anita“, whose execution took place from September 1st, 2011 until the 31st of May of 2012. The tool assumes control of five companies dedicated to the rental of formwork and scaffolding equipment, the costs incurred by each company have been counted weekly for 39 weeks, taking an adequate follow up to the valuations to avoid negative deviations from the budgeted. The valorization control tool has been developed entirely in the Microsoft Excel program; this program has been the most suitable due to its versatility for the correct supervision in view of control items defined by the work. It is important to mention that this control has the following considerations: 1. The planning of works must be respected in the great majority, over the duration of the work, since control is not possible if the initial planning is not respected. 2. The channeling of information on the income from materials to work, must be the responsibility of technical office, backed by the warehouse manager. 3. There must be only one person in charge of communication to the companies of formwork equipment, and must be the only person who can give the approval for the entry or return of materials. With these considerations the program is diagrammed to the need of work, in the designated control items and with the supplier companies chosen before with the help of comparative table. This starts the valuation control every week, being updated whenever there are incomes or returns of units of the formwork equipment. In this way an adequate control of valuations was carried out in the work “Mall Aventura Plaza - Santa Anita“, a work considered of great importance in the category of shopping centers.
