Soil Suitability for Geothermal Heat Pumps (Closed-Loop Horizontal Residential)
Ground source heat pump systems provide a viable alternative to conventional heating and cooling systems in the move towards sustainable building solutions. The most important factor for successful operation of a ground loop heat system is the rate of heat transfer between the pipe and surrounding soil.
Chain Survey Steps - Method for Performing Chain Surveying
Chain survey is the simplest method of surveying. In this survey only measurements are taken in the field, and the rest work, such as plotting calculation etc. are done in the office. This is most suitable adapted to small plane areas with very few details. If carefully done, it gives quite accurate results. The necessary requirements for field work are chain, tape, ranging rod, arrows and sometime cross staff.
Problems and Defects in Hardened Concrete
Defects in concrete can often be related to the lack of durability of the concrete, resulting from the composition of the concrete, poor placement practices, poor Quality Control or the aggressive environment in which it is placed. Cracking, Spalling, Scaling, Honeycombing, Settlement, Alkali Aggregate Reactions, Piping, Loss of binding paste.
Scope, Benefits and Problems in Environmental Impact Assessment
The study of EIA effectiveness shows a number of difficulties and constraints, generally although not universally applicable, that continue to prevent and hinder EIA from consistently delivering these advantages and benefits:
What is Environmental Impact Assessment and its Objectives
An environment impact Assessment is an event or effect, which results from a prior event. It can be described as the change in an environmental parameter, over a specific period and within a defined area, resulting from a particular activity compared with the situation which would have occurred had the activity not been initiated.
