Encontrar suficientes trabajadores calificados para realizar el trabajo puede representar un obstáculo. Dependiendo del tipo, tamaño y ubicación del proyecto, puede haber una escasez de trabajadores en el mercado, lo que puede afectar las tasas de mano de obra y la disponibilidad. Además, el nivel de habilidad y la experiencia de los trabajadores pueden variar significativamente, lo que puede afectar la calidad y la eficiencia del trabajo. Para abordar este desafío, investigue las condiciones del mercado laboral, ajuste las tasas laborales en consecuencia y verifique las calificaciones de los trabajadores.
To get information on the availability and skill level of workers, you can consider the following methods: 1. Job Boards and Recruitment Platforms: Explore popular job boards and recruitment platforms specific to your industry or region. They can provide insights into the availability and skills of job seekers through the number and quality of applicants for different roles. 2. Networking and Professional Associations: Engage with professional networks and industry-specific associations. These communities can provide firsthand knowledge and insights on the availability and skill levels of workers within their respective fields.
Using union skilled labor can go along way to helping complete a project properly and on schedule. These workers are trained in their craft and taught proper safety means and methods to utilize on job sites. Skilled labor often translates to better quality projects. When there are labor shortages then overtime hours need to be considered or looking for travelers from other locals is an option.
We cannot just stop a project because of market availability. Skilled workers tends to go who pay bigger. If that is the case, a factor for productivity must be added.
Understanding the project schedule as it relates to your current backlog of work will help you determine the need to hire more field support. Another factor could be weather if new construction. Schedule could be pushed if poor conditions come up, which could help (or hurt) the other jobs on your books. Aside from hiring, working overtime could be an option to maintain schedule provided materials are readily available.
Depending on the project, difficulty, location and trade. I'll place a dedicated job advertisement with a post in any specialized job board. Instruct HR team to properly validate skills with correct documentation and finally offer a rate based on experience and availability.
Estimating labor and productivity presents several challenges, including variability in work conditions, unpredictable human factors, and changing technologies. Accurately assessing labor needs and productivity can be complicated by project complexity, economic factors, and the quality of historical data. Additionally, factors like non-productive time, human resource issues, and measurement difficulties further complicate the estimation process. Addressing these challenges requires a mix of historical data, expert judgment, and ongoing adjustments to improve accuracy.
Common challenges in estimating labor and productivity include variations in skill levels, which can lead to inconsistencies in work pace and quality. Weather conditions, site access, and project complexity also impact productivity, making it tough to predict timelines accurately. Labor availability and turnover can create delays and disrupt productivity, while unforeseen obstacles or design changes often cause rework, affecting both cost and schedule. Estimating software helps, but it’s essential to adjust assumptions regularly and consider local market conditions to minimize inaccuracies and reduce risk in labor estimates.
Estimating labor and productivity faces challenges like varying skill levels, which affect work speed and quality. External factors like weather, site access, and project complexity can slow progress, making timelines hard to predict. Labor shortages or high turnover disrupt schedules, while unexpected design changes often lead to rework, impacting both costs and timelines. Accurately factoring in these variables requires regular adjustments based on local market conditions and historical data, as well as collaboration with field teams to refine productivity assumptions and reduce risk in estimates.
Definir y medir la complejidad y el alcance del trabajo es otro desafío. La complejidad y el alcance del trabajo pueden afectar la cantidad y el tipo de mano de obra requerida, además de las tasas y factores de productividad. Por ejemplo, un proyecto complejo o grande puede requerir mano de obra más especializada, coordinación y supervisión, equipos y materiales, y medidas de seguridad y calidad. Para abordar este desafío, divida el trabajo en unidades manejables y medibles, use estándares de productividad apropiados y tenga en cuenta cualquier requisito especial.
This is not labor or productivity issues rather than site management. Different productivities for same trade but different areas of the project is not realistic. To solve this dilemma is to split the area with different subcontractors.
Las condiciones del sitio y el clima a veces pueden ser difíciles de navegar. Afectan la accesibilidad, la seguridad y la eficiencia del trabajo, junto con la disponibilidad y el rendimiento de los trabajadores. Por ejemplo, un sitio remoto o congestionado puede plantear desafíos logísticos y de transporte, un sitio peligroso o inestable puede requerir más medidas de protección e inspecciones, y un clima cálido o frío puede reducir la productividad y la moral de los trabajadores. Para abordar este desafío, visite y evalúe el sitio, planifique cualquier preparación o mejora del sitio e incluya cualquier ajuste o asignación relacionada con el clima.
Also, in the military, we add a rainy day to every 100 mandays to hopefully take care of the possible delays from the weather, it's a risk we know it's going to happen especially if you're in an area where it rains a lot (Known - known), thus, plan for it.
You cannot do anything if the issue is weather. Productivity tends to slow down during bad weather. For tropical areas, access road constructed first. For hot and dry areas, time management is essential. For cold and icy areas, permanent enclosure was added in the design.
one of the famous challenges in Arab Guld, the hot weather in summer. Sometimes shifting working hours to be as early as possible be realistic. But sometimes even start working early cannot be very beneficial and the working hours by law and by humanity should be decreased.
Otro desafío es elegir y aplicar los estándares y métodos de productividad. Los estándares y métodos de productividad son herramientas y técnicas que estiman la cantidad de mano de obra requerida para completar una unidad de trabajo, como horas-hombre por pie cuadrado, producción de la tripulación por día o duración de la tarea por artículo. Sin embargo, hay muchas fuentes y variaciones de estándares y métodos de productividad. Estos incluyen, como publicaciones de la industria, datos históricos, opiniones de expertos o propuestas de contratistas, que pueden diferir en calidad, precisión y aplicabilidad. Para abordar este desafío, debe seleccionar y validar los estándares y métodos de productividad que mejor se adapten a su proyecto, ajustarlos a cualquier factor específico del proyecto y documentar sus suposiciones y fuentes.
Is addition, compare the latest productivity of 3 projects in the same country or region. That is the reason why experiences is more important.
Un quinto desafío de estimar la mano de obra y la productividad es evitar o minimizar errores e incertidumbres. Los errores e incertidumbres son los errores y desviaciones que pueden ocurrir en el proceso de estimación, como errores de cálculo, errores de datos, errores de estimación o errores humanos. Los errores e incertidumbres pueden afectar la fiabilidad y validez de su estimación, así como su reputación y rentabilidad. Para abordar este desafío, debe seguir un proceso de estimación sistemático y consistente, utilizar datos y herramientas confiables y actualizados, verificar y verificar sus cálculos y resultados, y aplicar técnicas apropiadas de análisis y gestión de riesgos.
The most important thing is to check and verify calculations through a detailed tracking system, helping the team to detect easily all possible human errors. Making an organized and detail-oriented analysis of the budget calculation, even through the entire life cycle of the project will allow you to catch most of the errors which can break the entire budget.
The best bet is to do a two person integrity (it's not about trust), catch all possible human errors. You can't just solely rely on a single point of failure because he or she is a subject matter expert.
Aside from human error during the estimating stages which can sink your budget, uncertainties are probably the most difficult part for an estimator to address.its a good idea to pull in other team members like a supt or project foreman to review the estimate together and point out any uncertainties for discussion before bidding. A proper turnover once the job is won will further help explain the thought process during the estimate. Future estimates can be adjusted from a “lessons learned”experience.
Other common challenges on projects that can create issues in your estimate besides weather conditions are the changing requirements of the owner, or building management related to making noise and or deliveries. There could also be site limitations for heavy equipment usage and daily clean up for general public safety. Sometimes overtime is required by your crews or subcontractors to meet these requirements. It’s important to find out these details while putting your estimate together so you can capture these costs properly in your estimate. Be sure to list how you intend to satisfy these added expectations on your proposal. This should help the client level your competitors proposals as well.
