“…Poor skill level and knowledge of labourers and lack of piling construction expertise were identified as next significant barriers where RII was 0.647 and 0.640 respectively. It was similarly confirmed by Zhussupbekov and Omarov (2016) who identified that the poor skill level of labourers significantly influences the waste generation, quality of works, completion schedule, and the overall cost. Involvement of the most appropriate piling…”

“…The lack of having such kind of rules and regulations reflects as a major barrier. Zhussupbekov and Omarov (2016) have highlighted that the lack of skill level is also a barrier to sustainability, as sustainable construction needs skilled workers for the minimization of material wastages and maximizing process efficiency for added value by minimization of resource depletion, minimization of environmental degradation and creating a healthy built environment. Lack of coordination to manage resources more efficiently in piling construction is also a barrier for sustainable construction.…”

“…Shan et al (2017) have concluded that the level of knowledge and awareness of project participants, especially project managers, with regards to environmental impacts of piling construction processes needs to be enhanced. Gaikwad and Shelavale (2017) have agreed with Zhussupbekov and Omarov (2016) by pointing that enhancing the awareness of the major environmental impacts of piling construction processes will help to improve the effectiveness of environmental management systems.…”

The construction of pile foundation is a multifaceted activity among rest of the construction activities that are performed by heavy machines, materials, and energy sources generating substantial amount of CO2 and greenhouse gases along with many other forms of environmental pollution. Sustainable piling construction guarantees that the whole piling process meets environmental sustainability and ultimately human health and wellbeing. Many countries around the world, including United States, China, the United Arab Emirates, are in the forefront of reengineering piling construction activities. Implementation of sustainable practices in piling construction Sri Lanka is still at a low level. Succinctly, several hindrances and barriers can be identified when adopting sustainable piling construction practices. Hence, the aim of this paper is to identify the environmental impact due to the current piling construction practices in Sri Lanka and to investigate barriers in implementing sustainable piling construction practices. A questionnaire survey was conducted among thirty (30) experts in piling construction. Significant barriers were identified using the relative importance index technique in data analysis. The findings revealed that among the ten (10) barriers identified, cost overrun and poor pile design, investment risk, lack of awareness of sustainable techniques and technologies as the top three (3) barriers in implementing sustainable piling construction practices. The study clearly identified the need for improving sustainability practices that can also enhance cost-effectiveness and performance efficiency. Findings of this study will be useful in formulating strategies to overcome the barriers and improve sustainability practices in the local construction industry.

“…For large capacity, the test can be conducted with bi-directional testing (O-cell testing (Osterberg 1984,). In this test, the load cell is hydraulically driven, high capacity, sacrificial jack-like device, installed within the foundation unit at the chosen location typically half way down the "capacity length" of the foundation in a manner in which the upper and lower portions of the foundation unit are tested against each other [7][8][9][10][11][12][13][14]. The Bi-Directional static load test by O-Cell, invented by Prof. Osterberg, is a hydraulically powered, sacrificial load cell that is installed within the test shaft.…”

The article presents the results of vertical static load tests of diametral and deep bored piles specially conducted at the construction site of EXPO-2017 in Astana, Kazakhstan. The methodology for determining the bearing capacity of the pile is summarized. Bored piles with a length of 31.5 m and a diameter of 1000 mm were tested. Vertical static load tests were conducted for the following load configurations: Bidirectional Static Loading Test (according to ASTM D8169), Static Compression Loading Test according to ASTM D1143-07 and Static Loading Test according to GOST 5686-12. The method presented in the paper can serve as practical guidelines to assess the capacities of bored piles installed in the field. This geotechnical investigation is important for understanding the soil-structures interaction on difficult soil ground conditions related to the construction sites.

is paper examines shaft and base grouted concrete piles by conducting vertical static load tests (SLTs) and dynamic load tests. ree concrete piles with shaft and base grouting, with base grouting only, and without grouting techniques were selected, and compressive SLTs were conducted. Two piles with grouting were also assessed with dynamic load tests. Another two uplift SLTs were conducted to one shaft and base grouted pile and one pile without grouting. Traditional presentations were provided to check whether the bored piles reached the design requirement. Interpretations of test results were also provided to determine the ultimate pile capacity. Results from these 5 SLT programs indicated that double-tangent and DeBeer's methods are close to each other, and Chin's method overestimates the pile capacity. Comparison of the results from the SLTs and dynamic load tests shows that the results from Chin's method are close to dynamic results, and Mazurkiewicz's method overestimates for friction resistance. e results also demonstrate that base and shaft grouted pile and base grouted pile increase by 9.82% and 2.89% in compressive capacity, respectively, and compared to the uplift SLTs; there is a 15.7% increment in pile capacity after using base and shaft grouting technology.
