New procurement approaches combined with performance-based building approaches should reduce costs, but empirical qualitative and quantitative studies are lacking. Performance-based maintenance contracts give maintenance suppliers incentives to improve their way of working. Innovative, cost-effective solutions that meet the performance criteria can be achieved, especially if the principle of whole-life costing is being adopted. Indirect cost savings are expected as well. It enables maintenance contractors to assume responsibility for certain activities for which they are better equipped to perform than their clients. A calculation model was developed that calculates the net present value of the direct (product) and indirect (transaction) costs at project level for a competitive maintenance tendering approach and for performance-based maintenance contracts. The findings show that performance-based maintenance contracts reduce both direct and indirect costs compared to a competitive tendering approach. Essential preconditions are an early supplier involvement and longer term contracts, giving opportunities for maintenance product and maintenance process improvements.

Nauji pirkimo būdai, derinami su subalansuotos statybos būdais, turėtų mažinti išlaidas, tačiau trūksta empirinių kokybinių ir kiekybinių tyrimų. Veiklos rezultatais pagrįstos priežiūros sutartys skatina priežiūros paslaugas siūlančias bendroves tobulinti savo darbo būdus. Galimi novatoriški, taupūs sprendimai, tenkinantys rezultatyvios veiklos kriterijus, ypač taikant viso naudojimo laiko išlaidų (angl.whole-life costing) principą. Tikimasi sumažinti ir netiesiogines išlaidas. Priežiūrą atliekantiems rangovams tai leidžia prisiimti atsakomybę už tam tikrą veiklą, kuriai vykdyti jie turi daugiau priemonių nei jų klientai. Sukurtas skaičiavimo modelis, kurį taikant apskaičiuojama viso projekto tiesioginių (produktas) ir netiesioginių (sandoris) sąnaudų dabartinė grynoji vertė (NPV), kai vykdomas priežiūros darbų pirkimo konkursas ir kai sudaromos veiklos rezultatais pagrįstos priežiūros sutartys. Rezultatai rodo, kad, lyginant su pirkimo konkursais, veiklos rezultatais pagrįstos priežiūros sutartys mažina ir tiesiogines, ir netiesiogines išlaidas. Būtinos sąlygos - įtraukti į priežiūros vykdymą tiekėją ankstyvuosiuose etapuose ir sutartis sudaryti ilgesniam terminui, suteikiant galimybių tobulinti produktą ir priežiūros procesą.
