It is impossible for a MEP subcontractor to build an interference-free MEP system, each trade has its own specialized knowledge, difficult to know the requirements of others; hence, MEP subcontractors hold the coordination meeting periodically, spend lots of time and money to find out the solutions of engineering problems, but only make a little progress at each meeting.

New development of the P and H-P version finite element method with quasi-uniform meshes for elliptic problems Jianming Zhang1, a, and Yong He1, b,* 1Department of Engineering Mechanics, Kunming University of Science and Technology, Kunming 650500, P.R.
In recent three decades, the finite element method (FEM) has rapidly developed as an important numerical method and used widely to solve large-scale scientific and engineering problems.
In the fields of structural mechanics such as civil engineering , automobile industry and aerospace industry, the finite element method has successfully solved many engineering practical problems, and it has penetrated almost every field of today's sciences and engineering, such as material science, electricmagnetic fields, fluid dynamics, biology, etc.
Since then remarkable progresses for the p and h-p version in one and two dimensions were made in the 1980s and 1990s, see e.g. [2,4,5,6,7,8,9,10,11,12,13], and the p and h-p version were implemented in commercial codes and used in practical engineering computation.

Application of Fuzzy Pattern Recognition in Spalling Risk Evaluation of Concrete Structures at High temperature Rongtao Li College of Civil and Architectural Engineering, Dalian University, Dalian 116622, China Lirongtao@dl.cn Keywords: concrete structures, high temperature, spalling risk, fuzzy pattern recognition Abstract.
To consider the potential benefits of concrete and its increasing usage, how to precisely forecast and effectively prevent the heated concrete spalling is one of the important issues studied in the fields of civil engineering both at home and abroad.
Practical engineering applications indicate that the proposed method is not only simple, but also precise, with the evaluated results well agreeing with the practical conditions.
