The art of Forecasting


(traducción en español debajo)

One of the most common mistakes made in construction projects is to rely on an “accounting control” as your cost control index. Accounting control is the subtraction of income – expenses and even when it seems to make sense, it really doesn’t.

living organismIn a construction projects, there are so many variables that we can not base the cost control by only focusing on incomes and expenses. There are change orders, extraordinary costs, un-foreseen and scope changes. All this affects the project’s cost in such a way that an accounting “control” is insufficient to predict how the project will finish.

Accounting control is a “square” control that you will never know how your work is going, it is even dangerous to use as an indicator of your project status.

A “cost control”, however, will forecast. There is a very good practice in construction known as “ACR” (Anticipated Cost Report), which tracks your project and forecasts its result in short and long term. It begins with making a good schedule, having the most accurate progress reports as possible, and also recording changes and while keeping an eye on contingencies, in summary, it is the result of many other processes and procedures.

The risks of not using a proper cost control could be disastrous, it’s just like walking down a street in Mexico City, because you actually do not know until you get hit, and believe me, you try to walk the streets in Mexico City and you will get hit if you are aware.

 Remember, the construction is a living organism, it constantly changes. A good manager must be able to predict and use his intuition, on how, when and where this organism is moving to push it right back on track before it’s too late.

El arte de pronosticar.

Uno de los errores más comunes de los proyectos de construcción es confiar en un control contable, el control contable es la resta de ingresos – egresos y aunque se puede escuchar que tiene sentido realmente no tiene lógica alguna.

living organismEn un proyecto de construcción existen tantas variables que no podemos cerrar el control de costos en solamente ingresos y egresos. Existen órdenes de cambio, adicionales, complementos e incluso cambios de alcance. Todo esto afecta el costo de tal manera que un “control” contable, es insuficiente para predecir cómo va a terminar el Proyecto e incluso cual es el estatus actual de él.

Un control de costo que pronostique tus gastos es un muy buen indicador en el momento y a futuro. Sin embargo, lleva un gran esfuerzo realizarlo, desde un buen cronograma, a tener avances lo más preciso posible, así como el registro de cambios y contingencias, es decir es el resultado de varios procesos y procedimientos previos.

Se recomienda siempre llevar el control de costos contra el avance real vs planeado, así como el pronóstico de lo que falta por cobrar.

Recuerden la construcción es un ser vivo en constante cambio, un buen administrador debe poder pronosticar e intuir que tanto se está moviendo y hacia donde se dirige.
