Information-Prediction Automatic System (IPAS) was developed for the Baltic Sea shore within the Kaliningrad District in 2005-2006 years and implemented in the State Organization of the Kaliningrad District "Baltberegozaschita" (coastal management authority) in 2007. It is used as database for shore protection engineering and a tool for analyses and forecasting of coastal processes, and has three blocks - database, forecast block and information-cartographic block. Information-cartographic block regularly accumulates the results of annual monitoring - surveys on shore segments with returning period of 6-7 years using reference system of permanent monitoring bench marks each 500 meters on the Vistula Spit, shore of Sambiya Peninsula and the Curonian Spit. IPAS is regularly used for processing and analysis of data, preparation of analytical notes for the Government of Kaliningrad Oblast and for municipal authorities. Information stored in IPAS was used for development of two programs of actions: "Protection of the shore of the Baltic Sea, the Vistula and Curonian lagoons within the Kaliningrad Oblast for the period 2014-2020 years" and "The concept of integrated development of shore protection in the Kaliningrad Oblast for the period 2013-2020 years". Optimal engineering solutions were recommended by using of the forecast block of IPAS for promenade protection constructions in Zelenogradsk and Svetlogorsk as well as for the project "Construction of beach protection in Svetlogorsk".

The Impact

One of the obstacles in project construction is that the project is experiencing delays. The delay is influenced by several factors including the absence of risk recording, the unavoidability of the opportunities and the impact of risks that arise in the project and its handling, and the neglected risks that may disrupt the project. Project risk is the cumulative effect of an uncertain event opportunity, which affects the project objectives. Several methods can be used to handle the occurrence of project risk, one of the methods used to perform a risk assessment is the Probability Impact Matrix (PIM). PIM is a method that can be used to analyze risk qualitatively based on probability and its impact. By using the PIM method, some of the opportunities and impacts of risks that may arise in the project can be identified. In addition, the PIM method can minimize the risks that arise in the project and quickly resolve the risks. Index Terms— Project, Risk, PIM, Possibility, Impact

The complex three-dimensional traffic construction often occur when the lower structure cannot bear the construction load and other special cases, indicating the need for temporary reinforcement of the lower structure. In this paper, combined with a project construction example, various temporary reinforcement technologies are adopted to solve the insufficient bearing capacity during understructure construction, which poses a serious danger, to ensure synchronous construction of the understructure and viaduct. Compared with the traditional construction technology, the temporary reinforcement technology proposed in this paper features the advantages of saving project cost and time and has achieved better economic and social benefits.

The steel building system of residence project has more advantage in environment protection and project management than the traditional residence project construction. The main steel structure residence components can be manufactured in the green construction base as the manufacturing industry. The key issue to realize the green construction model of steel building system of residence project is to apply with a suitable model of green construction base. This paper introduced four types of green construction base which are different levels related with project, enterprise, industry and region to combine construction industry with manufacturing. The TOPSIS method was applied to evaluate and analyze to figure out the optimization model of green construction base in steel building system of residence project.

The field monitoring of dangerous landslide is an important measure for guaranteeing its safety, especially when surrounded by large-scale construction. The landslide located nearby a reservoir in Shandong province. To guarantee construction safety, we adopted the automatic monitoring method for monitoring surface displacement and the internal soil pressure. The whole system uses solar power to provide energy and uses GPRS to transfer data. This system not only can provide reliable information for project construction, but also promote the application of environmentally friendly, low carbon in the monitoring field of civil engineering.

In modern mining and project construction, how to make use of the explosion energy effectively is the key technology demanding prompt solution at present. The application of air-decked blasting technology has enabled the efficient use of explosion energy, which proves that the air-decked blasting technology can overcome many disadvantages caused by column charge effectively, getting ideal explosion effect. Based on the dynamic finite element analysis software with the material model of Mat-Plastic-Kinemetic, the dynamic stress characteristics and failure mechanism of blast-hole near-field with level soft interlayer are researched with different air-decked charge structures. There is significant effect on the rock at the middle of blast-hole if top-air-decked charge structure with indirect initiation and middle-air-decked charge structure with two ends initiation at the same time. If bottom-air-decked charge structure with indirect initiation, soft inter-layer don’t change the peek of compression and tensile stress curves of typical elements with distance from the bottom of hole, so there is not effect significantly of level soft interlayer on bottom-air-decked charge structure with indirect initiation.

Set Up

As more and more non-public fund entering rural drinking water safety engineering project market; it becomes very necessary to built rural drinking water safety engineering project guarantee mechanism. This paper proposes three steps of mechanism design. Firstly, history data is used to fit multivariate linear equation set up describing relationship between bank loss and key risk factors. Secondly, guarantee fee is calculated through model regression, which is threefold of possible bank loss. Thirdly, guarantee fee is adjusted according to variety of key risk factor in the process of project construction and operating.
