Starting in May 2021, green building is mandatory for new buildings in Indonesia. Greenship is a green building certification system in Indonesia issued by the Green Building Council Indonesia (GBCI) which is a member of the World GBC for the conservation and efficiency of resources (energy, water, land, materials, and nature). Greenship will be implemented in MICE which is a building for Meetings, Incentives, Conventions, and Exhibitions that has a strong economic attractiveness in Indonesia, which has a population of 270 million. Using the SEM-PLS it was quickly concluded that energy is the most influential factor in achieving platinum ratings from GBCI. With the value engineering (VE) method and life cycle cost analysis (LCC), it is needed an additional 4,689% cost for the platinum grade green costs through energy optimization will get a payback period of 3 years and 10 months. The novelty of this research, since the design, it is necessary to take steps to measure energy efficiency and other resources with a selection of materials/machines and working methods of the green concept to know the amount of additional initial costs that do not much burden investment costs compared with some future benefits of green MICE

In green concept hospital work, several provisions must be obeyed so that all processes, including material selection, project implementation, and building operations, must refer to green principles. Green building planning and construction costs higher than conventional by 10-20%. By using the Value Engineering (VE) method and combined with the Lifecycle Cost Analysis (LCCA), the researcher applies the green hospital concept to a project which is a case study but is still cost-effective even lower than the original Bill of Quantity. To see the strong influence of effectiveness on the hospital project, the researcher distributed a questionnaire to stakeholders. The results of the questionnaire were processed and analyzed using the Statistics Products and Solution Services (SPSS) tool. VE is implemented after first creating a Function Analysis System Technique (FAST) diagram, before and after adding functions for certain work items. It turns out that the use of the VE and LCCA methods is very influential in improving cost performance. From the calculation of the VE method, the resulting costs are up to 2.62% of the initial cost and LCCA shows the payback period of the Solar Power Plant with time = 9.64 years ≈ 9 years 7 months. The novelty of this research is the selection materials and the green concept of working methods is still cost efficient and the installation of Photovoltaics (PV) on the roof of Hospital reaches a payback period which is feasible for new investment.

Modern industry confronts engineers completely new challenges. Technical skills in the light of the ongoing changes are no longer the only criterion for the effective work of engineers. On the other hand, engineers clearly show the need for development and taking new challenges. The need for a comprehensive acquisition of competences in both technical and psychosocial areas is increasingly expressed. Paper presents a model of employee competences essential for the future of enterprises operating in the Industry 4.0, which was created with using the Value Engineering methodology.

Purpose: of this paper consists of identifying and prioritising control tests of a product design with integrating QFD and VE techniques according to use of the lean approach to increase the productivity of product design. Design/methodology/approach: of this research is the application of four quality houses at QFD (four matrices) and VE matrix and assessment table of lean approach in the form of a combinational process. Findings: of this research were the implementation of mentioned methodology for numerical application. Bullet-head drill (27.8 inch HSD) that was applied in oil and gas industries with 5.69 scores is more than moderate in related to lean of control tests, and it is 7.13 from 9 for average survey results of applied mentioned methodology, and also it is 0.825 for research reliability. Research limitations/implications: of this paper suggest that the wide use of the other non-statistical techniques of quality engineering can be achieved with simple programming in excel and lean approach. Even more advanced topics in fuzzy circumstance can be applied with this methodology. Originality/value: of this research is extracted from three matrices of QFD, one matrix of VE and assessment table of lean approach for prioritising the control tests in product design of bullet-head drill 27.8 inch HSD.

Kolejna perspektywa budżetowa Unii Europejskiej to szansa dla firm budowlanych na nowe lukratywne kontrakty. Z ok. 30 mld € przyznanych Polsce w ramach polityki spójności na realizację projektów infrastrukturalnych sfinansowana zostanie m.in. budowa 71,5 km autostrad, 1790 km dróg ekspresowych oraz 35 obwodnic miast. Duża liczba inwestycji z jednej strony oznacza szybki rozwój i wzrost gospodarczy kraju, a dla przedsiębiorców większe możliwości pozyskania atrakcyjnych zleceń, z drugiej jednak każe nam – nauczonym doświadczeniem poprzedniej perspektywy – spodziewać się problemów niemal na każdym etapie procesu inwestycyjnego, a co za tym idzie, opóźnień w oddaniu gotowych dróg do eksploatacji. Lekarstwem na te bolączki mają być nowe zasady realizacji projektów drogowych, które – zgodnie z założeniami ich pomysłodawców – pozwolą prowadzić działania szybciej, sprawniej i taniej.

Another EU financial framework gives construction companies an opportunity to win lucrative new contracts. The funding from approx. € 30 billion allocated to Poland under the cohesion policy for the implementation of infrastructural projects will cover, among other things, the construction of 71.5 km of motorways, 1790 km of expressways and 35 ring roads. The large number of projects on the one hand means rapid development and eco-nomic growth of the country and more opportunities for businesses to get attractive contracts, but on the other hand, based on the experience from the previous financial framework, we may expect problems at almost every stage of investment process, and thus delays in putting completed roads into service. These ills are to be cured by new rules for the implementation of road projects, which - according to the assumptions of their originators - will allow faster, better and cheaper action.

Frequent gridlocks and traffic jams during the periods of rush hours can result in long user delays and more vehicle emissions causing continuous degradation of air quality. The builtinfrastructure of densely populated cities and intercity travel by passenger and freight traffic lead to significant adverse impacts of traffic congestion on air quality, greenhouse gas emissions, and global warming. Transportation contributes 28% of energy related greenhouse gas emissions in the U.S. This paper shows that traffic related carbon dioxide (CO2) emissions are higher per capita for several rural and smaller cities compared to large urban areas in the United States. Inadequate use of mass transit, urban sprawl, construction of more roads and traditional stop-controlled intersections, and addition of more lanes to increase traffic capacity and ease congestion, are primary causes of significant vehicle emission inventory of CO2 and air quality degradation. It is shown that sustainable traffic management policies, such as reduction of work-related travel by cars and more use of mass transit modes, can decrease CO2 emissions. Case studies of value engineering applications are presented to select cost-effective less polluting mass transport strategies based on economic evaluation of life cycle costs and benefits.
