OCJENA USPJEHA PFI PROJEKATA U REPUBLICI HRVATSKOJ PRIMJENOM KRITERIJA USPJEHA "DATUM POČETKA UPORABE"

Private Finance Initiative (PFI) is a model of Public Private Partnership (PPP) used to deliver public services which are not commercial in nature. Naturally, clients want to achieve successful PFI projects and they need to have a tool for evaluating the achieved success. Generally there are still no accepted frameworks for assessing project success but several recommendations for development of an evaluation template for assessing the success of PFI schemes exist. To enable success assessment there is a need to identify adequate success criteria. In this paper, important PFI project success criterion for lient called "Starting Date of Operation" will be identified. Model for its application on evaluating PFI project success will be recommended and its empirical applicability on suitable PFI projects in Croatia will be demonstrated. Descriptive statistics indicator will be calculated and referent base for success evaluation of PFI projects in Croatia applying "Starting Date of Operation" success criterion will be established.Privatna Financijska inicijativa je ugovorni oblik Javno-privatnog partnerstva koja se koristi za nabavu javnih usluga koje nisu komercijalne naravi. Prirodno, naručitelji žele realizirati što uspješnije PFI projekte te trebaju raspolagati sa alatom za ocjenu ostvarenog uspjeha. Općenito, još uvijek ne postoji prihvaćeni okvir za ocjenu projektnog uspjeha, ali postoje preporuke za razvoj okvira za ocjenu uspjeha PFI projekata. Da bi se omogućila ocjena uspjeha potrebno je identificirati odgovarajuće kriterije. U ovome radu, identificirati će se važni kriteriji uspjeha PFI projekta nazvan "Datum početka uporabe" (DPU). Slijedno će se predložiti model za njegovu primjenu kod ocjene uspjeha PFI projekta i prikazati će se primjenjivost na odgovarajuće PFI projekte u Republici Hrvatskoj (RH). Analizirati će se pokazatelji deskriptivne statistike te će se postaviti referentna osnova za ocjenu uspjeha PFI projekata u RH primjenom DPU kriterija

MODEL PROCJENE TROŠKOVA ODRŽAVANJA I UPORABE SVEUČILIŠNIH GRAĐEVINA

Costs of maintenance and operation are important part of the Life cycle costs. This paper describes development and validation of a new model for predicting average annual costs of maintenance and operations for the University buildings in Osijek with similar building characteristics. The model is developed based on historical cost data records obtained from 13 University buildings in Osijek for time period of 12 years starting from 1998. The model was tested at two new sets of data, in buildings outside of Osijek. The proposed operating and maintenance costs model requires reduced amount of data for predicting annual maintenance and operations costs of University buildings of similar building characteristics and highlights statistically significant data required for costs prediction. The model contains only few elements but yet can predict operating and maintenance costs. The proposed model enables maintenance and operations cost estimates already at the initial design phase.Troškovi održavanja i uporabe su neizostavan dio troškova životnog ciklusa. U radu se opisuje razvoj i validacija novog modela predviđanja prosječnih godišnjih troškova održavanja i uporabe sveučilišnih građevina sličnih karakteristika u Osijeku. Model je razvijen prema stvarnim troškovima održavanja i uporabe 13 građevina Sveučilišta u Osijeku koji su prikupljeni za vremensko razdoblje od 12 godina počevši od 1998. godine. Model je ispitan na dvije građevine slične namjene izvan Osijeka. Primjenom predloženog modela predviđanja troškova održavanja i uporabe uz malu količinu ulaznih podataka moguće je predvidjeti godišnje troškove održavanja i uporabe građevina slične namjene te omogućiti uvid u statistički značajne varijable potrebne za predviđanje spomenutih troškova. Predloženi model omogućuje procjenu troškova održavanja i uporabe već u fazi planiranja projekta

KRITIČNI KRITERIJI USPJEHA JPP/PFI PROJEKATA ZA NARUČITELJE

This paper examines PPP/PFI project success measuring concept for Public sector Clients. Relevant PPP/PFI project characteristics and generic project success measuring aspects have been recognized. Public sector Client is recognized as important PPP/PFI project stakeholder who has immense interest to measure project’s success. Current research practice of measuring PPP/PFI projects has been scarce with considerable inherited limitations. Proposed hypothesis states that is possible to identify relevant success criteria and structure success dimensions of PPP/PFI projects for Public sector Clients. Interpretation of these dimensions has been presented and recommendations for further research are proposed.Ovaj rad istražuje koncept mjerenja uspjeha JPP/PFI projekata za naručitelje. Prepoznate su relevantne karakteristike JPP/PFI projekata i bitni općeniti aspekti mjerenja uspjeha. Naručitelj je identificran kao važni sudionik JPP/PFI projekata koji ima veliki interes za mjerenje uspjeha projekata. Trenutna istraživačka praksa mjerenja uspjeha JPP/PFI projekata je oskudna s prisutnim velikim ograničenjima. Predložena hipoteza rada navodi da je moguće identificirati relevantne kriterije i dimenzije uspjeha JPP/PFI projekata za naručitelje. Prezentirana je analiza definiranih dimenzija te su navedene preporuke za daljnja istraživanja

Analiza osjetljivosti ukupnih životnih troškova građevina

Life cycle cost analysis of the constructed facilities provides insight into the planning, design, construction, operation, maintenance and disposal costs of the facilities. By applying this method during the early design phase it is possible to reduce maintenance and operating costs, plan future costs of ownership and prevent or reduce the impact of business interruption due to the maintenance and functional usability. The results of the life cycle cost analysis of facilities depend considerably on the period of life cycle cost analysis and the applied discount rate once net present values are populated. This paper presents life cycle costs case study analysis of the public facility for two different analysis periods, one of 30 and another of 50 years. Facility life cycle costs for both analyzed periods have been discounted to net present value using five different discount rate factors. Predicted construction costs are calculated based on Croatian construction standards, and operation and maintenance costs are based on analysis of historical data of similar constructed facilities in Croatia.Postupak proračuna ukupnih životnih troškova građevine daje uvid u troškove planiranja, projektiranja, građenja, uporabe i uklanjanja građevine. Uporabom ove metode u ranoj fazi projektiranja moguće je smanjiti troškove uporabe, planirati buduće troškove te spriječiti ili umanjiti utjecaj prekida poslovanja uslijed potreba održavanja i funkcionalne uporabivosti. Rezultati proračuna ukupnih životnih troškova građevine znatno ovise o duljini vremenskog razdoblja za koje se radi proračun i primijenjenoj diskontnoj stopi pri svođenju troškova na neto sadašnju vrijednost. U ovom radu napravljena je analiza ukupnih životnih troškova jedne javne građevine za vremensko razdoblje od 30 i 50 godina. Ukupni životni troškovi građevine oba vremenska razdoblja svedeni su na neto sadašnju vrijednost uz pomoć pet različitih diskontnih stopa. Predviđeni troškovi izvedbe građevine izračunati su na temelju podatka o etalonskoj cijeni građenja i korisnoj površini zgrade, a troškovi uporabe i održavanja na osnovi analize povijesnih podataka sličnih građevina
