A Methodology to Detect the Deviations of the Project’s Budget Compared to Market Prices.
(Horizon Research Publishing, 2015) Fuentes-Bargues, José Luis; González Cruz, Mª Carmen; Gonzalez Gaya, Cristina; Díaz de Mera Sánchez, Mª del Prado
The budget of a project reflects the cost of the investment needed to build an infrastructure, install a system or acquire new materials or supplies. A well-formulated budget in accordance with market prices, allows contractors to prepare offers according to their technical, economic and financial characteristics. On the other hand, it avoids current philosophies that aim to get the contract at any price. Philosophies subsequently used to point out problems and claims during the execution of the project (contradictory prices, delays, etc.) in order to recover some or the entire economic bid carried out during the tendering. In this paper a simple and fast methodology is developed to check if the tendering price is in accordance with market prices, so that the economic viability of the project is not at risk. The application of the methodology on a sample of projects allows us to check the influence of the type of project (civil or building) on the characteristics of the budget. It also allows us to point out the insufficient economic endowment of the projects as the start of the subsequent problems during the execution of the work.
A Methodology to Select the Price Criterion in Public Procurement
(Technics Technologies Education Management, 2015) Fuentes-Bargues, José Luis; González Cruz, Mª Carmen; Gonzalez Gaya, Cristina; Díaz de Mera Sánchez, Mª del Prado
The construction sector is a key driver for economic growth in any nation and public procurement is one of its pillars – hence the importance of the study and investigation of its mechanisms, especially tendering criteria. Price is the main deciding factor for most tenders and projects must have an appropriate base price relative to market price to avoid problems during the execution of the project. Most research on price criteria has been developed from the point of view of bidders and has discussed the development of tools and methodologies for determining the optimal bid price. In this paper we propose a methodology for public procurement procedures from the point of view of the administration. The methodology enables setting all aspects of the price criterion based on the size of the project budget, the nature of the work, and the number of bidders.
Agile Rediscovering Values: Similarities to Continuous Improvement Strategies
(American Institute of Physics, 2012) Díaz de Mera Sánchez, Mª del Prado; Gonzalez Gaya, Cristina; Arenas Reina, José Manuel
Research in the late 80's on technological companies that develop products of high value innovation, with sufficient speed and flexibility to adapt quickly to changing market conditions, gave rise to the new set of methodologies known as Agile Management Approach. In the current changing economic scenario, we considered very interesting to study the similarities of these Agile Methodologies with other practices whose effectiveness has been amply demonstrated in both the West and Japan. Strategies such as Kaizen, Lean, World Class Manufacturing, Concurrent Engineering, etc, would be analyzed to check the values they have in common with the Agile Approach.
Estudio de la Gestión de la Seguridad y Salud en el Sector de la Construcción Valenciano
(Departamento de Tecnología de la Edificación, Universidad Politécnica de Madrid, 2015) Fuentes-Bargues, José Luis; González Cruz, Mª Carmen; Gonzalez Gaya, Cristina; Garcia-Arambarri, Naiara; Díaz de Mera Sánchez, Mª del Prado
La construcción es un sector que presenta un alto nivel de siniestrabilidad debido a sus características propias (alto componente de mano de obra y que se desarrolla al aire libre) y por sus características organizativas, como los ritmos de trabajo, las metodologías de ejecución y la elevada subcontratación. La gestión de la Seguridad y Salud es un factor determinante a la hora de obtener mejoras en la ejecución de los trabajos y menores tasas de accidentes. En este trabajo se realiza un estudio del nivel actual de gestión de la seguridad y salud en el sector construcción en Valencia (España) a partir de una encuesta realizada a técnicos con experiencia en el sector. Los principales resultados obtenidos son que el tamaño de la empresa es un factor clave para la seguridad y salud, tanto en los aspectos de formación como en la gestión de la documentación de Seguridad y Salud. Los resultados muestran también cómo a pesar del tiempo transcurrido desde las últimas aportaciones normativas, tales como el Libro de Subcontratación o el Registro de Empresas Acreditadas, las empresas tienen un alto desconocimiento de la misma.
Influence on Manufactured Products Design of the Processes of Project
(Materials Science Forum. Trans Tech Publications, Switzerland, 2014) Díaz de Mera Sánchez, Mª del Prado; Gonzalez Gaya, Cristina; Rosales Prieto, Victor; Morales Camprubi, Felipe
A key factor to enhance industrial competitiveness is to develop strategies around product design, applying the concept of excellence in all its stages and emphasizing innovation efforts. The process of product design as an important element in the differentiation between competing products needs to lean on effective tools that help to meet the demands of customers in the global competitive markets. In response to this need it arises, the European regulatory paradigm on the design of products, standard BS 7000-2: 2008 [1]. It is worth analyzing the influence on the design of manufactured products of the processes of project management of predictive models used mainly. The processes described in each of the models covered along with those reflected in the aforementioned regulations will provide guidance on any differences or similarities in the various phases at project level.
Standardized Models for Project Management Processes to Product Design
(Procedia Engineering de Elsevier, 2013) Díaz de Mera Sánchez, Mª del Prado; Gonzalez Gaya, Cristina; Sebastián Pérez, Miguel Ángel
Excellence in design is an important differentiating factor between competing products; establishing a key pillar for companies face up with safety the challenges ahead in global markets. The implementation of process management, in turn, has emerged as one of the tools for improving management more effective and its application to design product powering growth vectors, such as innovation and productivity. A project level, the management model of the design process for products manufactured according to BS 7000-2: 2008 can be compared with the models predictive of project management, mainly international PMBOK ® guide and the model developed in Europe, PRINCE2. Potential similarities to be established in comparison shall take into account an integrated vision focus on all levels according to processes as initiation, planning, implementation, monitoring and controlling, and closing.
Strengthening Competencies in Learning of Industrial Safety focused on Projects
(Procedia Engineering. Elsevier BV, 2015) Díaz de Mera Sánchez, Mª del Prado; Gonzalez Gaya, Cristina; Morales Camprubi, Felipe; Rosales Prieto, Victor
The acquisition of the fundamentals to assess the importance of industrial safety needs tools to enhance practical learning of this subject. Evaluation techniques and risk prevention, the necessary protective measures, health and safety applicable to the industry and issues concerning the development of a Safety and Hygiene plan are aspects that must be integrated into the competencies of university technical degree. In a previous step, it will be obtained a panoramic of the degree of implementation of matters relating to industrial safety, limiting the study to equivalent degrees, to career of Industrial engineering, pre-Bologna, to provide data on the extent of this subject. It will check on which levels of degree, masters or doctoral studies, exists. The main objective, once obtained the above data, it will provide tools to strengthen practical learning through binding strategies university-industry based on the performance of different projects that satisfy the competences attached.
Tendencias Normativas en Gestión de Proyectos de Fabricación Sostenibles
(Anales de Ingeniería Mecánica. 2014, vol.1., 2014) Díaz de Mera Sánchez, Mª del Prado; Gonzalez Gaya, Cristina; Sebastián Pérez, Miguel Ángel
La creciente atención que suscita la evolución del cuerpo de conocimiento de gestión de proyectos, se articula con la ampliación al término “sostenibles”, para remarcar la necesidad de nuestra actual sociedad de conjugar las responsabilidades sociales, económicas y medioambientales en un mismo proyecto. Priorizar el cumplimiento de las leyes y regulaciones, tanto nacionales como internacionales, en la estrategia de desarrollo de nuevos proyectos de fabricación sostenibles, impulsa la creación de productos más eficientes y estimula los procesos asociados a la innovación. Las tendencias regulatorias en las áreas cubiertas por las responsabilidades que constituyen los denominados proyectos sostenibles, proporcionan un marco dónde encontrar un reflejo de los esfuerzos para unificar los conocimientos y buenas prácticas, según los estándares convenidos y ofrece ventajas para las empresas, como mayor facilidad para la toma de decisiones y un aumento de la velocidad de desarrollo de sus proyectos de fabricación. Diversos organismos califican la integración de la normalización en los proyectos como un criterio favorable para conceder su financiación permitiendo que los agentes implicados tengan una mayor seguridad en la apreciación del proyecto. La iniciativas europeas que promueven la normalización tienen su germen en la necesidad de responder más eficazmente a los retos de la sociedad con el horizonte 2020. La normalización refuerza su consideración como un servicio que aporta valor a las organizaciones apoyándolas en la implementación de sus estrategias. El objetivo del presente estudio es la identificación de algunas de las principales normativas utilizadas en los campos de cada responsabilidad, social, económica y ambiental, con la finalidad de reflejar los estándares más frecuentemente utilizadas por las empresas que operan en entornos de fabricación. El estudio se centrará principalmente en aquellas normas que directa o indirectamente pueden ser adoptadas por compañías que centren su actividad dentro de la Unión Europea, y más concretamente en España. Las citada normas se identificarán independientemente de aquella otra normativa regulatoria de aplicación, a los procesos de diseño y producción, por la pertenencia al Espacio Económico Europeo.
