Price recalculation model of construction contracts

Abstract

In recent years, the world economy has experienced rapid economic change in the construction sector and record inflation. The rapidly rising prices of construction materials and machinery in the construction market are also pushing up the cost of construction services. The main problem is that construction projects have been drawn up and contracts between clients and contractors have been awarded at previous prices, and it is therefore necessary to look for opportunities to index the price of construction contracts. The aim of the study is to propose a mathematical model and a smartphone application for the price recalculation of construction projects. The success of a construction project depends on the correct decisions taken at the stage of preparation and implementation of the procurement documents for construction contracts, a complex process requiring a lot of legal and technological knowledge. The proposed mathematical model would help clients and contractors to carry out the calculation of the price according to the construction price index quickly and without the need for extensive specialist technical expertise. The mathematical model is adapted to smartphones with Android software.

Statybos rangos sutarčių kainos perskaičiavimo modelis


Santrauka


Pastaraisiais metais pasaulio ekonomika patyrė spartų statybos šakos ekonomikos pokytį bei rekordinę infliaciją. Statybų rinkoje sparčiai kilo statybinių medžiagų bei mechanizmų kainos, didėjo statybinių paslaugų kainos. Didžiausia problema tai, kad statybos projektai parengti ir rangos darbų sutartys tarp užsakovų ir rangovų sudarytos ankstesnėmis kainomis, todėl būtina ieškoti galimybių statybos rangos sutarčių kainai indeksuoti. Tyrimo tikslas – pasiūlyti matematinį statybos projekto kainos perskaičiavimo modelį ir programėlę išmaniesiems telefonams. Statybos projekto sėkmė priklauso nuo teisingų sprendimų, priimtų statybos rangos darbų pirkimų dokumentų rengimo ir įgyvendinimo etape. Tai yra sudėtingas ir daug teisinių, technologinių žinių reikalaujantis procesas. Siūlomas matematinis modelis padėtų užsakovams ir rangovams greitai ir be didelės specialistų techninės kompetencijos atlikti kainos perskaičiavimą pagal statybos kainų indeksą. Matematinis modelis pritaikytas išmaniesiems telefonams su „Android“ programine įranga.


Reikšminiai žodžiai: statybos rangos sutartis, statybos rangos darbų kaina, kainos perskaičiavimas, matematinis modelis.
