Sobratema improves the methodology of its Equipment Hourly Cost program

NEW MODELS, CATEGORIES AND FAMILIES OF MACHINES WERE ALSO ADDED

 The Equipment Hourly Cost program of Sobratema – Brazilian Association of Technology for Construction and Mining brings new features. The first is the improvement of its methodology, which included new parameters which will improve the information available and will reflect better the current scenario of the market of equipment used in the main projects along the country.

The following important changes are among those carried out in the program’s methodology: the insertion of a new component, Wearing Parts – FPS (ground engaging tools), the inclusion of the DPVAT (compulsory insurance) in the calculation of the insurance cost and the insertion of the type of application of the equipment (light, medium and heavy) in the calculation of the track/tire hourly cost.

In addition, a reference value was suggested for each category of equipment in the Replacement Value (cost of new equipment) item. The calculation of the fuel and lubricant cost considered a composition of diesel fuel with 47 percent of diesel S-500, 49 percent of diesel S-10 and 4% of the additive Arla32. The reference value for lubricant was the average price per liter of the lube oil SAE 15W40 in the level API CJ-4 sold in Sao Paulo.

Another new feature of the Hourly Cost Program is the inclusion of cranes. Eighteen categories of five different families—TC, AT, RT, crawler cranes with telescopic boom and crawler cranes with lattice boom—were added. The program was increased from 15 to 20 families, from 32 to 50 categories and from 144 to 163 models. 

In addition, the program received an updating related to the value of the inputs which compose the hourly cost of each equipment: average sales price of new equipment, fuel, operation and maintenance labor and others. These values came from a survey carried out with the main equipment manufacturers, suppliers and users in the country.

The program Equipment Hourly Cost is interactive and allows the user to know the hourly cost of the main machines used in several types of projects. It allows the user, for example, to change the suggested parameters, to carry out calculations and to generate and store spreadsheets for reference. The access is free for the associates of Sobratema.

For non-associated companies and professionals, Sobratema makes available a summary presented as a table with the average value of 50 categories of equipment. The values inserted are related to normal operating conditions and do not include unproductive or non-working hours. The table is available in the official site https://sobratema.org.br/CustoHorario/Tabela or once a month in the M&T and Grandes Construções magazines.
