Water Quality control for construction sites is a requirement at any site within the United States. Erosion Controls are the first, and many times, last preventative measure for water discharge from a site. If these fail, streams, wetlands, or even off-site upland areas (yards, etc.) are adversely affected. Site quality is affected when valuable soil is lost and restoration requires replacement. Human exposure to contaminants, violation of governmental regulations, contractor reputation, and the overall economics involved in construction are at risk.

Clostridium tyrobutyricum represents the main spoiling agent responsible for late blowing defects (LBD) in hard and semi-hard cheeses. Its spores are resistant to manufacturing procedures and can germinate during the long ripening process, causing the burst of the cheese paste with a consequent undesirable taste. The lower quality of blown cheeses leads to considerable financial losses for the producers. The early identification of spore contaminations in raw milk samples thus assumes a pivotal role in industrial quality control. Herein, we developed a point of care (POC) testing method for the sensitive detection of C. tyrobutyricum in milk samples, combining fast DNA extraction (with no purification steps) with a robust colorimetric loop-mediated isothermal amplification (LAMP) technique. Our approach allows for the sensitive and specific detection of C. tyrobutyricum spores (limit of detection, LoD: ~2 spores/mL), with the advantage of a clear naked-eye visualization of the results and a potential semi-quantitative discrimination of the contamination level. In addition, we demonstrated the feasibility of this strategy using a portable battery-operated device that allowed both DNA extraction and amplification steps, proving its potential for on-site quality control applications without the requirement of sophisticated instrumentation and trained personnel.

With the rapid increase of the construction volume of our country's landscape industry, the scale of the stock gardens is getting larger and larger. Later gardening maintenance technology needs to be constantly updated, and management modes and methods should be constantly innovated to meet the development needs of the maintenance market. The quality of maintenance and management in the later stage of green space construction is intuitively presented to the viewers through the quality of landscape. Therefore, improving the quality control ability of green space is the most important thing for the rapid development of garden enterprises. This paper combines the Internet with traditional maintenance quality management through Internet thinking, and achieves several important points in quality control, such as planning, traces, inspection, reporting and customer service evaluation, on the Internet management and control platform. Among them, the work plan combined with the maintenance calendar, the climate and soil and other environmental data from all parts of the country can better guide the field work; Maintenance trace record can provide data feedback through pictures, videos, etc.; Patrol function discovers green space problems in time, records data of basic problems of green space and feedback processing; And reporting function can provide customers with more convenient maintenance services. The addition of customer evaluation forms an important closed-loop for staff management and site quality from the perspective of customers. To some extent, this study solved the problems of insufficient quality standards and low efficiency under the traditional maintenance management mode, which accords with people’s service demand for greening maintenance at the present stage, and helps to enhance people’s recognition of greening personnel. With the help of Internet management and control thinking, we can better solve the pain points existing in the development of maintenance enterprises, provide new tools for the better development of maintenance industry, and lay a foundation for the growth of maintenance industry.
