Archaeological researches at Gunung Wingko Site, Kecamatan Sanden, Bantul, had been conducted formore than 40 years ago. Nevertheless, the results of observations, interviews, Focus Group Discussions(FGD), and archaeological exhibition on Sanden Fair 2018 indicate that the existence and the culturalsignifcance of the site had only been known by certain communities. Local people unawareness of theexistence and the cultural signifcance of the site had so far caused site damage. Terefore, a number ofaction plans have been suggested during the FGD that involved the local people and some institutionsrelevant to the case of Gunung Wingko, and have to be done as soon as possible to prevent the sitefrom further damage. Te plans comprise dissemination of the site values, the establishment of thesite as cultural heritage (Cagar Budaya), site management, and the development of a site informationcenter. Tis center could be integrated with other tourist destinations which have been establishedaround the site. In this case, local people should be involved in preparing material displayed in theGunung Wingko Site Information Center.

The Ramesses III (KV 11) Publication and Conservation Project is currently developing a site management, conservation and publication strategy for the severely damaged tomb of pharaoh Ramesses III in order to prevent further deterioration and to preserve this cultural heritage site for future generations. Along with first urgent measures of conservation, a geo-archaeological survey of KV 11 and its surroundings, as well as a geomatic and photogrammetric survey of the tomb itself, were carried out. The detailed recording of the current state of the architecture and wall decoration allowed for further reconstruction of scenes and texts. Moreover, an archaeological sondage in the burial chamber revealed additional information about the ooding and sedimentation processes. A field school with students of Luxor University offered training in digital recording methods and epigraphy, geo-archaeological survey and mapping methodologies, and conservation treatment and assessment. The following article outlines preliminary results in the fields of geology, conservation, recording, reconstruction, and excavation.

This article aims to outline how to deploy unmanned aerial vehicles (UAVs) for on sites use in South African construction. The use of UAVs is gaining traction in the construction industry, where cyber-physical systems are promoting digital-to physical transformation. Among others, UAVs help assures the safety of people in construction. For instance, they are controlled remotely while moving faster than humans into inaccessible, hard-to-reach, and unsafe areas of job sites. They can be equipped with various types of sensors to transfer valuable data to safety managers and assist with onsite safety monitoring. Based on realised gains and the need to motivate its use, this article uses presents a schema that could help managers deploy UAVs on construction sites for safety performance purposes. The literature-based report utilised the keywords unmanned aerial vehicles and safety in construction to search the relevant database. The findings reveal that the critical hazards on construction sites can be identified using UAVs to allow proactive execution of accident prevention methods. Given that the captured visual images and video clips provide site management with a bird's eye view of a site, corrective measures can be implemented through 'walkabout' and instant instructions. The virtual images and video clips also help to identify hazards and risks that may cause accidents on construction sites. There is significant scope for using UAVs to improve construction safety when appropriate guidelines are implemented.

Fieldwork at Amarna from autumn 2018 through autumn 2019 included excavation at a previously uninvestigated cemetery, the North Desert Cemetery, located approximately 600 metres south-west of the North Tombs. Several post excavation projects also continued. Those reported on here comprise the study of skeletal materials from the North Cliffs Cemetery, hair and textiles from the North Cliffs and North Desert Cemeteries, and pottery from the North Cliffs Cemetery. A site management and outreach project also continued.

The Giza pyramids, one of the world's most important archaeological sites, are threatened by urban expansion, pollution, conservation challenges, and the pressures of tourism. A critical need exists for effective site management to protect the archaeological riches of this important site. The author describes the implementation of a four-phase management plan initiated in 1988. In the first phase, an organization scheme for the site was prepared. Phase II defined a conservation and archaeological plan for the east side of the Great Pyramid and for the queens' pyramids. Phase III, which is ongoing, will define conservation of the three main pyramids, includes a tourism management plan, and will complete development of a site master plan. Phase IV will outline a program for ongoing archaeological research and conservation. The site management plan for the Giza Plateau provides a model for addressing a wide spectrum of environmental issues affecting archaeological sites.

The aim of this paper is to identify and classify the numerous managerial issues encountered in the management of personnel in confined site construction. For the purpose of this research, a confined construction site is defined as a site where permanent works fit the site footprint, extending to levels above and/or below ground level, leaving spatial restrictions for other operations (e.g. plant and material movements, materials storage and temporary accommodation etc.) and require effective resource co-ordination beyond normal on-site management input. A literature review and analysis, case studies incorporating interviews and focus groups, and a questionnaire survey were used in order to gain a comprehensive insight into the issues of management of personnel in a confined construction site environment. The following are the top five leading issues highlighted; (1) Accidents due to an untidy site, (2) One contractor holding up another because of the lack of space, (3) A risk to personnel because of vehicular traffic on-site, (4) Difficult to facilitate several contractors at one work location, and (5) Numerous personnel working within the one space. In today’s modern environment, spatial restrictions are quickly becoming the norm in the industry. Therefore, the management of personnel on-site becomes progressively more difficult with the decrease in available space on-site. Where such environments exist, acknowledging the numerous issues highlighted above, aids site management in the supervision and co-ordination of personnel on-site, thus reducing accidents, increasing productivity and increasing profit margins. As on-site management professionals successfully identify, acknowledge and counteract the numerous issues illustrated, the successful management of personnel on a confined construction site is achievable. By identifying the numerous issues, on-site management can proactively mitigate such issues through adopting counteractive measures and through successful identification of the traits identified.
