Rework merupakan salah satu kontributor utama pada pembengkakan biaya dan keterlambatan proyek dan dapat memberikan dampak buruk pada performa dan produktifitas, baik konsultan maupun kontraktor. Penelitian ini mengambil topik factor-faktor penyebab pekerjaan ulang pada pekerjaan konstruksi bangunan Gedung di Kota Lhokseumawe. Target responden pada penelitian ini adalah sebanyak 63 responden dari pemilik proyek, konsultan pengawas, dan kontraktor pelaksana. Penyebaran kuesioner dilakukan secara luring dengan penilaian berskala Likert. Analisis faktor-faktor yang menyebabkan rework dilakukan dengan analisis regresi liner berganda. Dari hasil penelitian diperoleh hasil bahwa diketahui bahwa untuk faktor desain dan dokumentasi, subfaktor detail tidak jelas merupakan penyebab terutama penyebab munculnya rework. Subfaktor kurangnya control menjadi subfaktor pertama penyebab rework dalam faktor manajerial. Subfaktor material terkirim tidak sesuai posisi pertama pada faktor sumber daya. Dari hasil analisis regresi linier berganda antara variabel terikat efek-efek terjadinya rework dan variabel-variabel bebas berupa faktor-faktor penyebab rework diperoleh model regresi linier yang signifikan adalah dengan variable-variabel bebas kurangnya antisipasi keadaan alam, nekerja tidak sesuai prosedur, dan kurangnya pengetahuan bahan.","PeriodicalId":40130,"journal":{"name":"Portal-Godisnjak Hrvatskog Restauratorskog Zavoda","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136194082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This question occurs in all segments of society, including those segments related to cultural heritage. When we mention the term ‘cultural heritage’, the first thing that we associate with it relates to the past, our identity, to legacies or to something we have inherited. We identify it mostly with something valuable and something that we must protect. In this paper the protection of cultural heritage will be moved to the future. The main question asked is whether current views on heritage preservation/protection will be valid in the future. This paper is primarily about anticipating the future, and not predicting it, by showing the methods and techniques that identify processes that could affect the future of heritage protection and management in the Republic of Croatia. Research and definition of trends have been carried out, in accordance with which this paper anticipates possible changes in the approach of people towards cultural heritage conditioned by social, economic, technical, ecological and political trends. Based on established trends, several scenarios are developed with certainties and uncertainties. Scenarios lead us to a consensus about what kind of future we want, and they point out the possible problems facing the modern world and their impact on heritage.","PeriodicalId":40130,"journal":{"name":"Portal-Godisnjak Hrvatskog Restauratorskog Zavoda","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82233767","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They were revisionist, selective, discriminative, substitutive, integrative and reconstructive, and they are seen as reflexes of political realities and professional standards in fascist and early republican post-war Italy, as well as in the early communist Popular Republic of Croatia.
