The influence of roofing project on project cost: in the process of roofing project, if we use new thermal insulation material to replace traditional aerial insulation board of reinforced concrete and some other energy-saving materials and measures, the cost per square meter will increase 8 to 10 yuan, but this investment shares 1.5% to 2.0% of civil engineering cost.
We can see that the energy-saving investment of residential building of frame shear structure occupies 4% of total cost of energy-saving building, much less than the standard of no more than 10% in Civil Building Energy Saving Standards.
It follows that it will bring much more economic benefit in building maintenance than the increased cost in engineering construction with proper materials.

Applying a Spatiotemporal Object Database to an Urban Pavement Management System Jyh-Dong Lin1, a, Chia-Tse Hung2,b and Chien Ta Chen3,c Department of Civil Engineering, National Central University 1No.300, Jhongda Rd., Jhongli City, Taoyuan County 32001, Taiwan, R.O.C.
In recent years, pavement engineering has gradually moved from new construction work to maintenance and management.
Finally this can help engineer with their decision making and preserve feedback based on their experience for pavement management.
Literature review This skill method is not generally used in civil engineering research, especially in road engineering and management.
Is has not yet been used much for civil engineering applications, especially in road engineering and pavement management although there are, more and more research centers including ESRI(ArcGIS),  University of Sydney ,and Britain’s STEMgis[4] ‧ ESRI(Tuple-timestamping) This software was developed by the ESRI company and, use ArcGIS Desktop’s Arc View.

This aspect, together with the intrinsic structural complexity, heterogeneity and irregularity, directs the present research towards a topic not yet sufficiently investigated by the research community of architects and civil engineers.

Introduction The monitoring and diagnosis of the property of concrete structure, detection for the structural damage and safety hazards timely, evaluation for the safety of large engineering structure, are important areas of civil engineering disciplines.
With the construction of large-scale engineering structures, the increase of large span and super large span of engineering structures occurs, the problem of safety and durability of engineering structures has become particularly prominent.
Since the 70s of last century, the developed country like Europe and the United States, annual maintenance costs of existing projects for durability problem have accounted 1/2 of the total civil engineering expenditure that year [1] [2].
For a long time, our engineering design of concrete engineering structures, mainly focus on monitoring the acceleration, strain and displacement parameters which reflect structural changes, few consideration for the engineering and structural safety durability caused by the deterioration of the property of materials [3].
