Jednostavna formula za ranu procjenu troškova na građevinskim projektima ; A simple formulation for early-stage cost estimation of building construction projects
U okviru ovog istraživanja poboljšana je formula koja omogućuje jednostavnu, točnu i brzu procjenu troškova u ranim fazama građevinskih projekata (ESCE). Spomenutu formulu za procjenu ESCE-a razvili su autori na temelju umjetnih neuronskih mreža i evolucijskog programiranja gena. Kvantitativna analiza provedena je na stotinu građevinskih projekata, te je izrađen odgovarajući niz podataka. Taj niz podataka analiziran je pomoću većeg broja umjetnih neuronskih mreža kako bi se odredile varijable koje utječu na procjenu ESCE-a. Konfiguracija algoritma provedena je pomoću evolucijskog programiranja gena, te je na temelju te konfiguracije izrađena formula ESCE. Ta formula omogućuje dovoljno preciznu procjenu ESCE-a. Primjena predložene formule za određivanje troškova u ranoj fazi projekta omogućuje brže i jednostavnije izračunavanje troškova, ali isto tako sprječava pojavu bilo kakvih razlika do kojih bi moglo doći zbog individualnog pristupa proračunu. ; This study is aimed at improving a formula that enables easy, correct, and fast estimation of an Early-Stage Cost of Buildings (ESCE). This formula, enabling estimation of ESCE, was developed by the authors based on artificial neural networks and gene expression programming. A quantity survey was conducted for a hundred construction projects, and a data set was created. This data set was analysed with many Artificial Neural Networks to determine the variables that affect ESCE. An algorithm configuration was made with Gene Expression Programming, and the ESCE formula was created using this algorithm configuration. This formula estimates ESCE with satisfactory precision. The use of the proposed formula in the early-stage building cost calculations is important not only for faster and easier cost calculation but also to prevent any differences that may arise due to the individual making the calculations.
