Peculiarities of using small-diameter bored piles for effective solving of geotechnical problems

Abstract. The peculiarities of the use of small-diameter drill piles in modern construction considered, with an emphasis on their advantages and areas of application in specific conditions. Two main types of piles distinguished: cast-in-place, which characterized by continuous reinforcement and filling with concrete or cement mortar, and composite, where the load transfers to reinforcing elements. Main advantages of small-diameter bored piles noted, including the possibility of performing work in confined spaces, reducing the level of noise and vibrations, a variety of drilling technologies, the possibility of application in geological conditions of varying complexity, etc. Particular attention paid to the areas of application of small-diameter bored piles, including the installation of new foundations, underpinning of existing structures, soil improvement and land-slide protection. The main groups of factors that can influence the choice of small-diameter bored piles as the main design decision for various fields of application considered, including: - physical factors (restricted access, remoteness of the area, distance of piles to existing structures); - subsoil factors (difficult geological conditions, soil liquefaction tendency); - environmental factors (sensitivity to vibration/noise, hazardous or contaminated soils); - necessity of adaptation to existing structures; - load/settlement requirements; - economic factors. Limitations for the use of small-diameter drill piles from the point of view of their efficiency described. An example of the effective practical use of small-diameter bored piles in the confined conditions of dense urban development in close proximity of metro tunnels with increased requirements regarding the level of vibrations and noise considered. The task of minimizing subsidence of the designed residential and office complex and the impact on surrounding buildings and structures solved. The compliance of the adopted design decisions confirmed by means of field tests, as well as using the results of settlements monitoring. Attention focused on the need for further improvement of design approaches and technological solutions to optimize the efficiency of small-diameter bored piles for solving geotechnical problems.

Three phase microcontroller based automatic change-over selection switch

The significance of electricity in a developed country cannot be underestimated because power instability problem affects the economy growth, productivity and infrastructure development. The issues of phase failure, losses and phase imbalance earth fault are main causes that lead to unstable and erratic power supply. Most homes and office complexes where single-phase supply is needed are supplied with three phases of power supply to allow change from one phase to another when there is fluctuation or complete outage of power supply on a particular phase. This operation is normally done manually and has caused a setback in terms of time wastage, strenuous operation, susceptibility to fire outbreak, electric shock and high maintenance frequency. When voltage supply on a phase is below 220V or above 415V, this system automatically disconnects the load from the phase and connects to another where the required condition is met. Therefore, this paper presents a Microcontroller Based Automatic Transfer Switching System which is made up of voltage sensing circuit, Hall Effect current sensor, relays, LEDs and LCD of PIC16F877A microcontroller. A system flow chart was developed, programmed with MikroC software and simulated using Proteus electrical software design. A 10KVA single phase generator was used as alternate power source. The load capacity of the design was determined by decoupling Maxwell’s Equations of 8KW and power loss using pointing vector equation as 0.25% of the peak load. The switch is tested to have function optimally within ±5% nominal voltage of 220 - 415V supply and produced approximately 20 seconds elapses during the entire process of power supply changeover. Hence this device is suitable for Industrial and Domestic use where 3-phase power supply is available with a stand-by power source.

Enhancement of work place comfort through the use of soft landscape

The work environment has been shown to have a great influence on employees’ physical and mental state, as such employers try as much as possible to provide a comfortable working environment. However, recent studies have shown that the work environment is no longer as comfortable as it used to be due to heat gain from the increasing use of hard landscape features and neglect of soft landscape features in the work environment. This has resulted in stress causing both mild and severe health conditions for employees. Thus, this study aims to analyze the use of soft landscape in enhancing users' comfort with the view of reducing stress and health-related issues in the work environment. The paper adopted a mixed method using observation checklists, structured interviews, questionnaires, and case studies. A total of eighteen office complexes were selected to describe the existing situation as related to most office complexes and to also gain insight into the subject matter as already applied to life situations. Structured interviews and questionnaires were also conducted with occupants of the buildings and professionals to hear their perceptions and expectations of their work environment. Results showed that 20 percent of the offices give proper consideration to the use of soft landscapes in the work environment, and 40 percent give inconsiderable attention to soft landscapes while making use of them in small quantities solely for improving the aesthetical value of the building. In comparison, the remaining 40 percent do not consider landscape use as a means of improving comfort in the work environment. Findings also revealed that 80 percent of office buildings give major consideration to parking space using hard landscapes without a proper blend of soft landscapes after building design which hurts occupant comfort. The research concluded that the incorporation of soft landscape elements both within the building using recesses and protrusions and on the building walls through the use of exoskeleton and climbers while incorporating trees, shrubs, flowers, hedges and water around the building can have these required effects on employee’s comfort.

This initiative involves field observations, data collection, design presentations to stakeholders, and engages professors and students from the Architecture Program at the Faculty of Engineering, Universitas Kristen Indonesia, as a contribution to the community in the field of architecture.

Investigation on the source of VOCs emission from indoor construction materials using electronic sensors and TD-GC-MS

Indoor air quality (IAQ) is critical to the health and wellbeing of people. As the majority of people spend greater amounts of time indoors, either in office spaces or households, the level of air pollutants in such environments is critical. Building materials and furniture are known sources of air pollutants such as Volatile Organic Compounds (VOCs) and may be associated with discomfort, detrimental health of the occupants, etc. In this study, the VOCs found in a brand new office complex were monitored over a period of 6 months, with an emphasis on monitoring and quantifying harmful VOCs and identifying their emission source. Air samples were taken from a closed, unoccupied office space on a weekly basis and analysed using Thermal Desorption-Gas Chromatography-Mass Spectrometry (TD-GC-MS), while continuous monitoring of the air quality was performed using two commercially available IAQ sensors. To identify the source of the emitted VOCs, pieces of all construction material that were used in the office, including flooring, finished wall material, and adhesive glues, were removed, and placed in air-tight glass containers prior to analysis confirming that the source of VOCs is indeed the flooring. Identified compounds included mainly material origin VOCs such as BTEX (benzene, toluene, ethylbenzene, xylene) and styrene, but also common VOCs such as acetone and propan-2-ol. Of significant importance was the concentration of toluene that was found to be the most abundant VOC in both the flooring material and the indoor air.

Identifikasi Konsep Arsitektur Tradisional Aceh Pada Bangunan Pemerintahan di Banda Aceh (Studi Kasus: Kantor Gubernur Aceh)

Abstract. Nowadays, there are many new office buildings built in Aceh, thus are for supporting the public service functions carried out by the Government of Aceh. The design of a government office building is a representation of the Government or a region. According to Saiful Anwar (2016), the Aceh Governor's office is one of the buildings that applies local Acehnese wisdom, namely elements from traditional Aceh houses (Rumoh Aceh). The Aceh Governor's office was built in 1990 and initially consisted of six building blocks, two of the building of this office complex were damaged by the tsunami in 2004 and then renovated afterward. Since the beginning, the Governor's office has undergone several changes and renovations due to the disaster, and during the renovation process adjustments were also made to the needs and functions of the building. The researcher aims to examine how traditional architectural values are applied to the Aceh Governor's Office Building in the current situation. The research was conducted by using the observation and interview methodologies. The variables being studied from the design of the Aceh Governor's Office are the physical elements of the building such as plans, orientation, appearance, carvings, and other finishing elements. The results of the study provide an illustration that the Aceh Governor's Office Building is a reflection of the combination of the values of Traditional Acehnese Architecture and Modern Architecture that developed in Aceh in the early days of this building being built. However, this study also found that there were two masses of buildings that had undergone renovation after the Tsunami disaster in 2004 that did not apply Acehnese architecture at all in their designs.

From Desks and Chairs to Lap-Tops and Software: A Study Focusing on the Impact of Modern Work Place on the Future of REITs in India

Abstract: A workplace generally corresponds to a place where a person goes to work, either for his/her employer or for own self. Traditionally, the scope of such a location was confined to a sizable office complex or a factory but the Midas-touch of technological development not only led the evolution of businesses but has also revolutionized the workplaces. In the wake of lockdowns imposed as a result of the COVID-19 pandemic, many companies around the world and India were forced to implement flexible working models. What once seemed a far reality, has now become the most adopted mode of working by organizations globally. Flexible working arrangements are developing swiftly, their variations are proliferating, and have gained popularity. The idea of being able to work remotely from the comfort of your own home has been a big advantage in terms of cost cutting for many companies as it frees them from the compulsion of boasting huge office spaces but has also went on to present multiple challenges for the real estate firms and trusts that are engaged in the business of renting the office spaces. Thus the current research paper focuses on the identification of key factors that have proved to be instrumental in driving this immaculate change and the associated challenges that are present for REITs in India.

Enhancing green infrastructure in cities: Urban car parks as an opportunity space

Interest in radical solutions to embedding Green Infrastructure (GI) into the built environment are at an all-time high. With land value often preventing more mundane forms of GI, key actors, such as planners, developers, architects and others, are increasingly exploring novel methods for embedding the features. This innovation involves a surge in green roofs, living walls and other systems which enables nature to thrive in otherwise hostile environments. Many of these systems are embedded on or within office complexes, universities and various ‘clean’ buildings within cities. However, there is a nascent movement to using urban car parks to enhance GI. In this opinion piece, we reflect on the opportunity space here and the potential to upscale work around embedding GI into urban car parks: exploring good practice, barriers to implementation and recommendations for moving the activity forward.

COMPETENCE-BASED RECRUITMENT OF NON CIVIL SERVANT STATE EMPLOYEES FOR THE INTERNAL SECURITY DIVISION, SECRETARIAT GENERAL OF THE HOUSE OF REPRESENTATIVES OF THE REPUBLIC OF INDONESIA

The security system stipulated in the Decree of the Leadership of the House of Representatives of the Republic of Indonesia Number 51/PIMP/III/2008-2009 concerning General Guidelines for Security Management in the Office Complex of the House of Representatives of the Republic of Indonesia, is a Standard Operating Procedure that has been implemented so far. The security system applied is a zoning security system with a security level of Very Important Person (VIP). To implement the system and level of security, it requires the support of Pengamanan Dalam personnel who have very good security competence. The research method used is a qualitative approach research method, where the data taken comes from three sources, namely the results of interviews with 14 key informants, namely 2 Members of the People's Legislative Assembly of the Republic of Indonesia, Echelon II Officials, Echelon III, Echelon IV Secretariat general of the House of Representatives of the Republic of Indonesia, and staff who are deemed to know the problem. Apart from that, field observations and document review related to the previous recruitment of internal security personnel. The results of the study have illustrated that the cause of the non-optimal results of Pengamanan Dalam personnel recruitment is the absence of Standard Operating Procedures, the absence of openness in its implementation so as to facilitate irregularities in the recruitment process. The resulting recruitment pattern in order to get competent personnel is, internal and external collaboration with agencies, transparency, clear competency standards and strong supervision and commitment.

MARSIM: A Light-Weight Point-Realistic Simulator for LiDAR-Based UAVs

The emergence of low-cost, small form factor and light-weight solid-state LiDAR sensors have brought new opportunities for autonomous unmanned aerial vehicles (UAVs) by advancing navigation safety and computation efficiency. Yet the successful developments of LiDAR-based UAVs must rely on extensive simulations. Existing simulators can hardly perform simulations of real-world environments due to the requirements of dense mesh maps that are difficult to obtain. In this paper, we develop a point-realistic simulator of real-world scenes for LiDAR-based UAVs. The key idea is the underlying point rendering method, where we construct a depth image directly from the point cloud map and interpolate it to obtain realistic LiDAR point measurements. Our developed simulator is able to run on a light-weight computing platform and supports the simulation of LiDARs with different resolution and scanning patterns (e.g., spinning LiDARs and solid-state LiDARs), dynamic obstacles, and multi-UAV systems. Developed in the ROS framework, the simulator can easily communicate with other key modules of an autonomous robot, such as perception, state estimation, planning, and control. Finally, the simulator provides 10 high-resolution point cloud maps of various real-world environments, including forests of different densities, historic building, office, parking garage, and various complex indoor environments. These realistic maps provide diverse testing scenarios for an autonomous UAV. Evaluation results show that the developed simulator achieves superior performance in terms of time and memory consumption against Gazebo and that the simulated UAV flights highly match the actual one in real-world environments. We believe such a point-realistic and light-weight simulator is crucial to bridge the gap between UAV simulation and experiments and will significantly facilitate the research of LiDAR-based autonomous UAVs in the future.
