New Classification of Construction Companies: Overhead Costs Aspect / Naujas Statybos Įmoni Ųklasifikavimas: Pridėtinių Išlaidų Aspektas

Abstract

The traditional classification of construction companies depending on the number of employees is not appropriate when analysing the competitiveness of construction companies. The collected data of Lithuanian construction companies was analysed by applying statistical methods and the construction companies were classified into competitiveness classes according to the relative value of the overhead costs. The new classification provides the basis for economical evaluation of the construction companies and modelling of their competitiveness in regard to the value of overhead costs as well as applying the competitive advantages for the estimation of construction bidding price. Santrauka Tradicinė statybos įmonių klasifikacija pagal įmonės darbuotojų skaičių nėra korektiška statybos įmonėms analizuoti ir jų konkurencingumui vertinti. Taikant statistinius duomenų apdorojimo metodus išnagrinėti Lietuvos statybos įmonių duomenys ir pasiūlyta nauja statybos įmonių klasifikacija į konkurencingumo klases pagal jų pridėtinių išlaidų santykinio rodiklio reikšmę. Sukurta nauja statybosį monių klasifikacija leidžia atlikti ekonominį statybos įmonių įvertinimą ir modeliuoti jų konkurencingumą pridėtinių išlaidų aspektu, suformuoti konkurencingą pasiūlymo kainą, įvertinant konkrečius statybos įmonės konkurencinius pranašumus.

Methods for the Calculation of the Lost Profit in Construction Contracts

“…This method is used to compare the profitability and productiveness of other companies in the industry (in our case the construction industry). In this method, the loss of profit calculator determines the various specifics of the contract-e.g., contracting for technologically similar work and in a similar or same region, or based on overhead costs [24]. The calculation of lost profits by this method is based on the assumption that the injured company would carry out a comparable activity with other businesses if it were not injured; alternatively, the average of the profits of several companies having similar parameters to the damaged company may be used [23].…”

Modelling Construction Site Cost Index Based on Neural Network Ensembles

“…On the other hand, an overhead cost of a construction project can be defined as a cost that cannot be identified with or charged to a construction project or to a unit of construction production [38]. A new classification of construction companies into competitiveness classes according to the relative value of overhead costs was proposed in Reference [39]. As far as accuracy is concerned, it is more advantageous to calculate both components separately-as is done in Great Britain [40], the US, and Canada [41].…”
