Precast concrete systems in developing vs. industrialized countries

Abstract



Precast concrete technology is recognized worldwide as offering significant advantages. Despite the advantages they offer, precast concrete building systems’ share in both Turkey and the U.S. is very low, especially when compared to many European countries. Since Turkey is a developing country that is technologically dependent on the developed world, low share of industrialized building systems is highly expected in that country. However, the U.S. is a developed and industrialized country, so it was very interesting to see that these systems are not extensively used in that country either. This study investigated the factors that prevent the extensive use of precast concrete systems in the U.S. and Turkey through an extensive questionnaire survey. The survey results revealed that the perceptions of the American vs. Turkish respondents on most of the factors that affect the use of precast concrete systems are significantly different from each other. While American respondents considered size and load restrictions on transportation, poor communication among parties, and lack of qualified contractors specialized in precast concrete systems as three most important barriers to the extensive use of precast concrete systems in the U.S. building construction market, Turkish respondents ranked lack of good communication among parties and lack of structural engineers and contractors specialized in precast concrete systems as the most important three factors that prevent the extensive use of these systems in Turkey. This study indicated that precast concrete users and manufacturers should recognize that the main reasons for low utilization of precast concrete systems predominantly depend on the prevailing conditions of the country in question.

Surenkamojo gelžbetonio technologija visame pasaulyje pripažistama del daugelio svarbiu pranašumu. Nepaisant ju, surenkamojo gelžbetonio statybos sistemu dalis Turkijoje ir JAV, palyginti su kitomis Europos šalimis, yra labai maža. Turkija yra besivystanti šalis, kurios technologiju pletote priklauso nuo išsivysčiusiu šaliu, tad maža surenkamosios statybos sistemos dalis yra pagrista. Tačiau JAV yra išsivysčiusi ir industrializuota šalis, bet šiu sistemu naudojimo mastas šalyje yra mažas. Remiantis išsamia apklausa straipsnyje atlikta maža surenkamuju betono sistemu naudojimo JAV ir Turkijoje apimti lemiančiu veiksniu analize. Apklausos rezultatai parode, kad JAV ir Turkijos respondentu nuomonL del daugelio veiksniu labai skyresi. JAV respondentai nurode, kad trys pagrindiniai veiksniai, ribojantys surenkamuju gelžbetonio sistemu naudojima JAV statybos rinkoje, yra: transportavimo apribojimai del dydžio ir svorio; silpnas ryšys tarp statybos proceso dalyviu; kvalifikuotu statybos rangovu, kuriu specializacija ‐ surenkamieji statybos elementai, trūkumas. Turkijos respondentai pagrindinLmis priežastimis laiko bendradarbiavimo tarp statybos proceso dalyviu stoka ir specializuotu statybos projektuotoju bei rangovu trūkuma. Atlikta studija parodL, kad surenkamojo gelžbetonio sistemu naudotojai ir gamintojai turetu pripažinti, jog menka surenkamuju gelžbetonio sistemu naudojimo apimtis pirmiausia priklauso nuo šalyje dominuojančiu statybos salygu.
