This will help to further enrich the understanding of professionals and policymakers and guide towards improving the quality of structural concrete production in Nigeria.
Water Water is essential for concrete production as it is necessarily needed for hydration and achieiving a workable mix.
Excessive water content weakens concrete, while insufficient water affects the workability negatively [19].
Evaporation of the mixing water, due to exposure to sun or wind, absorption of water by the aggregate, and water consumption in the formation of hydration products all contribute to stiffening freshly mixed concrete.
These results will aid the professionals in obtaining good concrete that will respond to their respective needs.

Possible causes of this defect are: (i) inadequate degreasing of substrate or contamination degreasing tank, (ii) imperfect drying of the substrate before spray painting or (iii) contamination of compressed air or rinsing water [4].
In a highly competitive paint shop environment, only the most professional companies can maintain the high standard of products using immediate analysis of any detected surface defects and corresponding process modifications.

Thirdly, agricultural operation subjects should be not only independent households with farming as their by-business, but more modern professional agricultural market subjects and professional farmers.
More efforts should be devoted in developing new market subjects such as peasants’ economic cooperation organizations, firmly farms, professional breeding and planting households, leading enterprises and so on.
Professional production and marketing should be improved to enhance the marketability.
According to the serialization of production, processing, storage, transportation and services, professional services should be offered to form an industrial chain; hi-tech agricultural parks should be established to integrate agricultural scientific researches, breeding, training, experiment, demonstration, agricultural sightseeing, and planting popularization, and also form the chain of production, processing and marketing.
Eco-environment of the farmland has been seriously polluted, soil quality largely reduced, soil and water loss as well as destruction of wildlife habitats caused due to the utilization of fertilizers, pesticides and mulching film, the improper treatment of straws, and the destruction of nearby forests.

Green low-carbon buildings in China started late, and lack of practical experience and basic data, the existing assessment system focused on the evaluation of the quality of the built environment, emphasizing the content of land, energy efficiency, water conservation, and materials, and neglect the building itself of the economy and the use of comfort, is not conducive to the interests of developers and building users, including green to maximize the effect, but also affect the promotion and development of low carbon buildings.
To get more people to understand low-carbon architectural concept should start from the popularity of the public areas of education and professional education of the building field.
On the other hand, in the construction sector need to strengthen professional education, cultivation of low-carbon concept, the master of low-carbon technologies for the development of low carbon construction industry professionals.
Secondly, to encourage specialization and commercialization of energy service companies to participate in the management of low-carbon buildings, the mode of regulation of contract energy management (EPC) services to allow owners to make energy service companies and professional cooperation, benefit-sharing.

Soil Mechanics is basic courses for civil engineering, hydraulic structures, farmland and water conservancy, soil and water conservation, power transmission lines and other professional major, is a subject to develop students ability to analyze problems and experimental ability.
Soil mechanics is an important professional basic courses for civil engineering and hydraulic engineering doctoral and key disciplines in China Three Gorges University (refer to CTGU).
Soil Mechanics is a deep content and wide extension subject, smaller to a single soil particles micro-structure, large to transport, civil engineering, water conservancy construction, Are the scope of the study of Soil Mechanics.

The water jet technology The medium of water jet is water [1], cutting or crushing objects with high-speed pressurized water jet from the nozzle.
The water jet technology use the principle of dissolution in water, cooling action and chemical action of water, when water has certain pressure, specific mechanical action of crush, cut, peel and transport will be showed by the water jet.
Effects of high pressure water jet were related to water pressure, flow, and nozzle diameter.
When breaking rock with water jet [6], water jet propagates crack but the cutting edge of rock.

MEP System Modeling BIM is a computer-aided solution which helps MEP professionals to design and construct the MEP system.
Under the consideration of modeling time and system similarity, we choose the lighting, duct, hot/cold water supply, and drainage piping system in the NCKU 2nd hospital as our modeling scope.
The construction process of fire protection is similar to hot/cold water supply system, but the water supply lines are more complicated than fire protection piping, the reason is the vertical water supply pipes has more interactions and relationships with Architecture and structure components.
Hence we choose hot/cold water supply system as our model instead of fire protection.
For the purposes of environment protection and prevention of contagious disease, the drainage system in the NCKU hospital can be divided into laboratory waste water, general waste water, contagious waste water, and storm drain system, these systems are designed as gravity driven, and producing the most reworks during the construction process, therefore we took it into our consideration too.

The excavation and fill may lead to the water and soil loss or landslide, and cause the change of living environment.
In construction it abandons or leaks the harmful substance, and produces the smoke dust, noise and vibration, but this will destroy the original communal facilities, pollute the water and even endanger the survival and reproduction of rare animals and plants in some areas.
Or organize construction carefully, according to the environment protection laws, make the professional standard for each link of construction, and super add the strict management to make the whole construction processes in perfect order, all the above are better thoughts and methods.
Otherwise, the upstream water rise is likely to change and flow if the water resistance is too large.
The supervision department should make professional standards in all aspects of construction according to the law of environmental protection and execute a strict management.

Kazakhstan's oil pipeline industry development Kazakhstan long distance crude oil pipeline is a professional operation of the company "Kazakhstan oil co., LTD" (hereinafter referred to as KTO), it was founded in 1997, its history dates back to the former Soviet period.
KTO have 5495 km oil pipeline, 2148 km of water pipeline.
The company's main business: 1) Through the long distance crude oil pipeline to provide oil and oil products transportation services, including product transfer, storage, mixed); 2) The organization through of other countries oil transportation pipeline transportation system Kazakhstan oil; 3) As the other company to provide oil pipeline operation and technical maintenance service; 4) And carry on some water the thermal, electric power transmission and distribution business etc.
KTO early use is primarily a soviet-era GОSТ national standard and CNPC construction standard, since the KTO in 2000 under the auspices of the former Soviet union specification for adaptation in the field of crude oil pipeline, forming the first set of their own industry standards (code РI), obtain the Kazakhstan of antitrust committee and ministry of energy and mines approved; KTO since 2010, according to their own enterprise development experience and draw lessons from the related international standard specifications for adaptation again (new code СТ), through the Kazakhstan's energy and mines department and the state of emergency committee approved and implemented the specification detailed rules on the oil pipeline running various professional technical requirements, scope of work, working procedure, operation records of different working procedure has a specific template.
