Building cost database for South Africa – key data trends and implications
Authors: Windapo Abimbola 
Published: December 2022

Abstract
The accuracy of any projections depends on the comprehensiveness of the report and the ability to gather appropriate data for the study. Inaccurate portrayals of any study will misguide the investor and result in project failure and loss of resources. Due to the current depressed state of the South African Economy, the construction industry’s value fell sharply and there was significant job loss. To help economic recovery, the South African government announced a ten-year infrastructure investment plan in housing among other sectors. The considerable deficit in infrastructure and housing in South Africa means that changes in building costs are important because of the implications of changes to affordability. This paper examines the trends in building costs in South Africa over five years and reconciles these indicators with other key socio-economic factors. The study analysed the indicators of Building Cost in the Medium-Term Forecasting Associates (MFA), Department Trade and Industry (DTi), and StatsSA database using descriptive and inferential statistics. The findings suggest a positive correlation between population growth, unemployment, poverty, and the growth in building costs. While it can be inferred that inflation and corruption have a negative impact on growth in building cost. The study recommends that investors should plan ahead and make projections on population, unemployment, and poverty to avoid project failure and loss of resources due to increased building costs.
Managing the risks associated with remote learning project implementation
Authors: Aranda-Mena Guillermo , Vaz-Serra Paulo , Edwards Peter 
Published: December 2022

Abstract
Academic institutions have faced substantial issues and difficulties since the novel coronavirus disease became pandemic. Traditional class attendance-based pedagogy rapidly became compromised, and universities were forced into alternative ways of delivering learning to students who themselves faced restrictions, even to the point of not even being able to enter the countries where they had enrolled for their studies. In the haste to implement projects for alternative learning delivery systems, there was little time to develop proactive approaches to project risk management for such implementation. By default, delivery risks were addressed re-actively, and a “lessons learned” post-implementation approach prevailed. Two case studies have been used to explore risk management practices used in alternative learning delivery environments. The findings show emerging teaching and learning dynamics in parallel with risk-managing delivery of course learning experience and content quality.

Abstract
Innovation of a firm is considered the firm’s ability to develop a new or improved product and processes or equipment for the creation and production of new invention. While customers or clients are essential to the realisation and success of innovation in construction firms. However, there is deprived understanding of the impacts of construction firms’ innovation on customers /clients. This paper, hence, exploratively determine the impacts of construction micro, small and medium enterprises’ (CMSMEs) innovation on customers/clients. To achieve this the research employed qualitative research method to exploratively determine the effects of innovation on construction micro, small and medium enterprises’ (CMSMEs) clients. While recorded semi-structured interview with opened ended questions were utilized to gather information from 43 innovative CMSMEs through judgemental and snowballing examining procedure. Information gathered were, open and axial coded, examined and interpreted. The outcome from the study reveal that innovation predominantly impacts on client/customer satisfaction, client/customer retention and client/customer relations. In addition, the findings also indicate minor occurrences of innovation impacting clients’/customers’ value for creativity, clients’/customers’ value for money and after sales services to clients’/customers. This outcome implies that innovation could be postulated as a driver of client satisfaction of a firm resulting in improved client retention and ultimately, the success of the firm. The search improves body of knowledge in respect of the basic effects of innovations on construction firm clients.
A survey on BIM information management: the approach of producers and consumers of model information in Brazil
Authors: Oliveira F M , Santos E T 
Published: December 2022

Abstract
BIM Information Management, namely how information is introduced in and consumed from building information models, have an impact on the efficacy and efficiency of BIM workflows. Implicit reliance on all the information contained in a model may result in non-value-adding work from model authors. The recommended alternative is creation and use of information according to the Project BIM Execution Plan specifications. Regardless the adopted approach, model asseveration is demanded from authors (i.e., the verification that all required information is reliable and is available on a released model). International standards, such as ISO 19650, require clear and rigorous specification of information need, but anecdotal evidence indicates that the current practices in local markets are far from those recommended by these standards. An extensive online survey was conducted to assess current practices of professionals from the Brazilian market. Results showed that about half of the respondents adopt document-based (MEA/MET) recommended practices when dealing with model information, while the other half kept a behaviour more akin to the older CAD workflows. The implicit reliance (without checking MEA/MET documents) on model information varies according to professional role, being lower for design professionals and coordinators and higher for construction managers. As standards evolve and introduce new concepts for deeper and more granular information management, such as the Level of Information Need, it is necessary that professionals adapt their practices for increased efficiency on their BIM workflows.

Published: December 2022

Abstract
There have been numerous research studies on understanding buildings better and finding ways to improve water and energy consumption while making them more comfortable for occupants. With technologies such as Building Automation Systems, IoT devices, mobile applications and BIM software, more data can be generated and stored for intelligence and more effective facility management. The next big thing is the digital twin concept, where a virtual model is created from the physical building that brings together real-time information from all data capture devices, allows monitoring, historical analysis, predictive analytics, and simulation as well as interaction and intervention to be carried out. Many research studies have covered the characteristics, architecture, and benefits of digital twins and examined the potential implementation issues. However, the literature on evaluating return on investment (ROI) and acceptance of digital twins for the built environment at the individual user level is limited. This study aims to develop a conceptual model to examine the motivational intent and behavioural choice by individual users to utilise the digital twin technology to improve their performance. The objectives of this study are to examine technology acceptance theories and develop a conceptual model that measures the relationship between the tasks involved and the digital twin technology characteristics.
A Common Configurator Framework for Distributed Design, Collaboration and Verification Across the Full AEC Supply Chain
Authors: Al Fisher  , Tsakiridis Georgios , Lombardi Alessio , Ahmad Maz , Watts Andy 
Published: December 2022

Abstract
The wider AEC industry has recently seen a growing number of platform-based approaches, focusing on the deployment of DFMA and industrialised construction. A common aid to this approach is the digital configurator, a software platform that allows for users to explore options with predefined constraints such as kits-of-parts. This paper argues that this approach has fundamental limitations, in particular that (1) configurators are developed as standalone products to context-specific problems and that (2) current implementations lack a capability for downstream and upstream flows of information between design and construction processes of a building. This research proposes an open-source Common Configurator Framework that institutes a separation between the authoring of objects for the design processes and rules applied in the verification processes; a consequent standardisation and reuse of sets of parts (objects) and sets of rules (specifications) is demonstrated. Additionally, this work formalises the decoupling of the downstream part verification process and the upstream design requirements definition, so that a Common Specification-driven design and manufacturing process becomes possible. The work is supported by a reference implementation based on the proposed Framework with a series of case studies, prototypical configurators and examples of verification/validation of pre-existing kits of parts against pre-authored specifications.
Paludiculture: peatland utilization to support climate change adaptation
Authors: Pratiwi D , Yuwati T W 
Published: December 2022

Abstract
Tropical peatlands are one of the largest carbon-storing ecosystems in the world. Draining tropical peatland causes environmental damage including greenhouse gas emissions. Drained peat is highly susceptible to fires that increase carbon emissions into the air. Rewetting is one way to solve the problem because, to achieve a zero or negative carbon balance, the water level should be close to or above the surface to maintain the water saturation of peat. The government of Indonesia has thoughtfully restored the peatland by implementing the 3R approach (rewetting, revegetation, and revitalizing local livelihood). After rewetting, paludiculture (wetland cultivation) is a promising land-use option for peatland. Through paludiculture, the peatland ecosystem will be improved which has already undergone drainage and will re-encourage carbon accumulative in peatland. This paper aims to determine the potential of paludiculture to support climate change adaptation including presenting challenges and opportunities in its implementation. Paludiculture has been shown to reduce greenhouse gas emissions by keeping peat moist. Besides having an ecological function, paludiculture also functions economically because it can be an alternative source of livelihood for people living around peat.

Published: December 2022

Abstract
The regions of upstream Cisadane watershed tend to gain more flash flood cases and reduce the water catchment due to encroachment of settlement areas. Researches on flash flood disaster and land use/land cover change are important to reduce the impact of flash flood disaster to the community and environment. This study aims to: 1). Determine morphometric characteristics and land use/land cover changes and 2). Prioritize sub-watersheds for flash flood disaster management. Land Use Land Cover (LULC) and morphometry parameters were used to prioritize the sub-watersheds as a basis for flash flood disaster mitigation in the research sites. The land use data from three different periods (2011, 2015, and 2020) were modelled to understand the land use change in the research sites. Morphometric characteristics were quantitatively analysed over three aspects including linear, relief, and shape aspects over seven sub-watersheds. Morphometric parameter was considered as an important parameter in order to understand the capacity and hydrology condition at a particular watershed towards precipitation rate. According to the land use change analysis gained from 2011 to 2020, the trend of land use change was dominated by settlement area and cultivated land. These areas tend to grow in 2015 and 2020. The integration results of LULC 2020 and morphometric analysis revealed that the Sub Basin 1 (SB 1) sub-watershed was the top most priority for flash flood mitigation planning, followed by SB 7, SB 3, SB 5, SB 4, SB 2, and SB 6.
Using local wisdom for climate change mitigation
Authors: Simarmata D P , Indrawati D R 
Published: December 2022

AbstractThe most frequent disasters that occur due to climate change are hydro-meteorological disasters that have an impact on human life. Structural and non-structural mitigation efforts have been carried out by the government and stakeholders. However, considering that human behavior also affects the occurrence of climate change, non-structural mitigation efforts need to receive special attention. On the other hand, the Indonesian people have local wisdom related to disaster mitigation, but currently, it has not been fully utilized. Therefore, the objective of this paper is to provide information and analyze some Indonesian local wisdom that can be utilized in disaster risk mitigation. The method used is a literature review. Based on the review, there are some local wisdom related to forest conservation, spring conservation, and soil and water conservation. Local wisdom in forest conservation as conducted in Aceh is using traditional law to manage their coastal forest, and in Bali and North Maluku by constructing forests as sacred places. Spring conservation using local wisdom can be found in Samigaluh, Kendal, and Sungai Langka, commonly by giving offerings, giving thanks, cooperation, and trusting spring as a sacred place that must be protected and respected. Local wisdom to conserve soil and water is applied in Aek Latong and Lerep villages by planting long-rooted plants on slopes to prevent landslides. The synergy of government efforts and the preservation of local wisdom is a good strategy for disaster mitigation.

Abstract
Strong earthquakes occur frequently with devastating effects on people and infrastructure. In cases of such catastrophic earthquakes, rescue and all other civil protection services need all available information about the earthquake itself and the consequences it has caused. In addition to the series of traditional sensors and systems used to interpret earthquakes and their consequences, remote observation sensors from space (EO) combined with geoinformation technologies (GI) are increasingly used today. By applying them, it is possible to quickly provide a wide range of useful information about the earthquake and the consequences it has caused, which traditional sensors and systems do not provide or need more time to collect and process them. Croatia was hit by two catastrophic earthquakes in 2020, on March 22nd with an epicentre in the Zagreb capital with a magnitude of 5.5 on the Richter scale and on December 29th with an epicentre next to the city of Petrinja with a magnitude of 6.2 on the Richter scale. Already after Zagreb earthquake a great need for spatial interpretation of the event and its aftermath has been recognized. Therefore, after the earthquake in Petrinja, a quick reaction of geodetic experts followed, using modern EO and GI technologies to provide information on the aftermath of the earthquake. This paper presents an overview of the sensors and systems, used data, their processing and the results obtained, i.e., the applications developed for crisis management purposes are presented.

Published: December 2022

Abstract
The Baribis Fault’s status, which is located in the northern part of Java, as an active or inactive fault is a matter of considerable debate. In this study, we investigate the strain rate of the Baribis fault zone’s segment in northeastern West Java, Indonesia, as revealed by a dense network of GPS stations. We analyzed 17 surveyed GPS stations combined with continuous GPS sites over West Java from 2017 to 2021, then we estimate the GPS velocities fields. We calculated the strain rate and estimated it from the GPS velocities. In general, the Baribis fault zone experiences a significant strain rate (> 50 nano-strain/yr) with the compressional dilatation strain associated with the ongoing deformation in that area. The dilatation strain suggest that the northeastern Baribis fault in the West Java is an active thrust fault system. This information is essential to supporting a disaster mitigation program.

Abstract
The Megacity Jakarta has encountered serious floods associated with high intensity but a short-duration rainfall or low intensity with a long-duration rainfall. During the rainy season, on 4 Feb 2021, Jakarta was inundated as rainfall intensity increased. However, little is known about the meteorological factors that might contribute to this heavy rainfall. In this study, we used the 6-min X-Band Doppler radar, one-hour satellite and reanalysis data to understand the spatial distribution of rainfall and explore the background conditions that might influence the enhanced rainfall over Jakarta and Bekasi River. Other than previous studies, we found that over Jakarta, the areas receiving high rainfall are more widespread and further to the northeast ocean with an intensity of above 4.5 mm h-1. High intensity of rainfall starts to develop in the afternoon over the inland areas at around 08-10Z (3.00-5.00 PM). Background condition shows a strong westerly wind speed crossing over Java Island, and this might initiate the development of rainfall over the region.

Published: December 2022

Abstract
Kulon Progo is the regency in Yogyakarta with high intensity of landslide exposure. Kulon Progo also facing a new era of regional growth which potentially increases the risk. Therefore, mapping the landslide risk is required for disaster risk management. The objective of this study is to map the level of landslide risk as part of disaster risk management in the Kulon Progo Regency. The method used to map landslide risk is GeoTOPSIS (Geospatial Technique for Others Preference by Similarity to Ideal Solution). The criteria used include the hazard aspect, namely the occurrence of landslides, the vulnerability aspect consisting of population density and the percentage of built-up in the area, and the capacity aspect, which includes the criteria of settlement regional services hierarchy and the number of disaster-responsive villages. The criteria’s weight is obtained through the entropy index. The results show that the Samigaluh district has a very high-risk level of landslide, followed by Kalibawang district with a high-risk level, Kokap and Pengasih districts are at a medium level, while Girimulyo and Lendah are at a low-risk level. Other districts are at very low risk. Thus, disaster risk management can focus on districts with high to very high level of risk.

Published: December 2022

Abstract
Mining is an activity with a high risk of accidents in open pit and underground mining sites. Various factors that cause accidents have been found through accident investigation, such as miners’ fatigue. Miner’s fatigue can be caused by environmental factors and workload that can be controlled to make a safe and comfortable working environment and prevent accidents. This research objective is to evaluate the relationship between environment factors in the form of heat stress index using humidex method and workload to miner’s fatigue level in the underground mining area PT. Dwinad Nusa Sejahtera. This research was done by measuring the working environment to know humidex, workload and miners fatigue level. Working environment conditions in the underground gold mine of PT. Dwinad Nusa Sejahtera is in a hot and humid condition with wet temperature range are 28.5–32.9°C, dry temperature range are 29.7–33.0°C, globe temperature range are 29.7–33.5°C wet bulb globe temperature range are 29.0–32.1°C, relative humidity range are 83.1–100% and humidex are 49.5–59.5°C. Multivariate analysis of miner’s fatigue level in all activity groups shows that the humidex variable gives more significant effects than the workload variable.

Abstract
Rainfall is one of the factors affecting stream water discharge and flooding. The high amount and intensity of rainfall frequently cause downstream flooding. In this regard, a study with the purpose to know the trend of rainfall, discharge, and land cover of Kaligarang or Garang Watershed was conducted. Kaligarang Watershed is located in Central Java, Indonesia. Secondary data were collected from published papers and related institutions. Land cover data were derived from Landsat images. A regression analysis was conducted to observe the trend of maximum rainfall and peak discharge. The simple regression was conducted between the time and maximum rainfall or peak discharge within the corresponding year. The results showed that maximum daily rainfall 1972-1980 tended to increase. Maximum daily rainfall from 1981 to 1990 slightly decrease, however, extreme rainfall occurred in 1990. Compared to the data 1972-1980, the maximum rainfall in the period of 1991-2010 was lower. The peak discharge of the period 1961-1970 tended to decrease, conversely, starting 1971 to 2017, the peak discharge tended to increase. The reduction of the dryland forest and plantation forest were observed from every decade starting from 1990, in contrast, the settlement increased 138% from 1990 to 2020.
