The cost of an electrical installation is therefore not limited, as we often imagine, to a pile of material costs with a fixed number of working hours, since the number of hours required is variable and directly linked to the quality and technological progress of the equipment used.
Rule # 1 is therefore to reason the overall cost of installing the finished electrical site to which must be added the cost of non-quality over at least the following two years.
WHAT IS THE COST OF YOUR ELECTRICAL INSTALLATION
Features. It sounds obvious, but the cost of an installation can vary depending on what you want to do. This can range from the most basic traditional electricity (than simple ignitions everywhere for lighting for example), to more advanced traditional electricity (addition of back and forth switches on the lighting for example), down to `` the most complex and configurable home automation systems. We must distinguish the addition of simple functionalities requiring just time and usual material in greater quantity (addition of lighting points in a room for example), of the addition of more complex functionalities requiring specific material and skills (like the remote control for these lights for example).
The number of hours to complete the electrical installation condition (including programming for some home automation systems). This article is generally considered incomplete because it must include lead times and supply costs (the longer and higher the costs, the greater the number of references and suppliers), the lead times for preparation, the replacement of errors of '' defective supplies or products, etc. And on the construction site itself, which has never fought with impractical equipment and which makes exposure times explode (low-end wires breaking when exposed, RJ45 sockets difficult to wire, tight image where you can't run your fingers, etc.)?
The personnel necessary to carry out the installation. The number of people needed is significant, but their level of qualification and experience can also have a significant impact on the overall cost. And beyond the cost, the less qualified staff facilitate interchangeability, minimize the costs of staff turnover and sick leave, facilitate the rapid search for workers to deal with surcharges (this flexibility is all the more appreciable when contracts include late penalties), etc.
Development time. The installation debugging time should not be ignored. It sometimes takes hours to find a simple wiring error destroying the slight additional cost that would have resulted from the systematic use of polarized connectors for example. Obviously, this is all the more true as the installation is complex. Certain installations may require a specialized Domitian for development, generating significant costs.
The costs linked to malfunctions over time. Unless there is particular justification, even if one might think that one piece of electrical equipment is worth another, a too marked difference in price generally masks inequalities in quality as invisible at first sight. Poor quality material will generally only show its defects over time. The impact will then have to be taken into account on the non-quality costs of the work previously carried out, which are always difficult to assess and generally underestimated (we think of the cost of the part to be replaced but rarely of the travel, work supply costs. , etc.). In this environment there is not really a "marketing" price (prices artificially high to make people believe in a superior quality): we generally have what we pay. For the same quality, it will also often be in your interest to invest in the latest generation of equipment. For example, switching equipment with spring-loaded terminals rather than good old screw terminals eliminates the risk of false contacts due to improper tightening (the concept of tightening often varies from one individual to another) or loosening in time.
