The term of time consuming includes components influencing the level of consumption of<br />

time in the process. In order to determine the dynamics of losses, one must determine the<br />

percentage of the level of losses compared to waste time and resources for a particular task.<br />

Time consumption determined in the step of planning is important for budgeting<br />

construction projects. The process of budgeting should firstly be expressed in natural units.<br />

Therefore, it is reasonable to use time in budgeting construction projects, as well as create<br />

opportunities for its control. This approach is mainly due to the tangible connection timeconsuming<br />

planning of the process which translates into budget planning for supply of<br />

investment. It must be replaced by a few rules (Nowosielski, 1999):<br />

a basis for budgeting should adopt standards of technical use of factors of<br />

production,<br />

costs should be structured by homogeneous generic items,<br />

budgeted costs should be split into primary and secondary process,<br />

the costs of primary and secondary process should be divided into variable and<br />

fixed,<br />

to determine the extent of liability for the costs generated in terms of controlled<br />

and uncontrolled cost by the head of manufacturing.<br />

Pricing was the time spent on tasks, usually expressed in units such as pln/hour or<br />

pln/minute. The level of time-consuming entered into the budget also determines the<br />

amount of time known as a reserve. This time is intended as a buffer possible to move from<br />

an action to an action. In practice, if there is a buffer time valued pln/hour for one of the<br />

tasks, it is possible to transfer the surplus to other action at a similar price. The aim of such<br />

proceedings in budgeting is to optimize costs over time.<br />

It should also be noted that the time-consuming is also inextricably linked to the laborintensity.<br />

Labor intensity is an element of time-consuming. Labor intensity is defined as the<br />

number of hours (minutes) necessary to complete action. Time consumption becomes an<br />

element of budgeting when it includes manufacturing and related factors such as (Wysocki,<br />

2008):<br />

abor intensity (P),<br />

number of employees in the task (I),<br />

realizing skills (U),<br />

the percentage of time that employees executing the task, they can devote to its<br />

implementation (P),<br />

organization of work (O).<br />

These assumptions can be represented by the following formula 4:<br />

.<br />

Time consumption is not always measured linearly; therefore, it is worthwhile to use a<br />

variety of techniques for estimating the time-consumption (Hammer and Champy, 1993).<br />

Time consumption is a part of budget analysis, because the possibility of using enterprise<br />

budgets developed based on activity based costing it requires the use of units of time as a<br />

carrier costs and management of costs (Dylewski, Filipiak and Szczypa, 2010). Budgeting<br />
