Fittings and pipes installation costs of on-site installation practices generally include labour, machinery, resources and equipment. A correct planning and an optimization of resources are essential for efficiency and cost containment on construction site; especially in extreme conditions that can facilitate the arise of problems and complications during the installation phase. Adopting best practices and choose suitable products for the installation conditions can help to reduce the overall expenses substantially, which are divided between fixed and variable costs.
1. Reduce costs without sacrificing quality, efficiency and speed.
Reduce the fittings installation costs by increasing skilled workforce
By increasing the number of skilled workforces, other expected fixed expenses (as machinery and equipment) may decrease for the period in which the site is active. Keep in mind, however, that this function is not directly proportional. Therefore, increasing the number of employees, the costs related to personnel administrative management and the rental of additional machinery will also increase. Therefore, it’s correct to spend some preparatory time figuring out where the right balance is.
Generally, we can suggest as a starting point for the composition of site-teams the following:
- Skilled workers with specific assignment within the site;
- Skilled workers with skills and abilities necessary to perform the work with artful precision;
- Common workers and performers needed to complete the work in a timely manner.
It is indeed important to have skilled and qualified employees in order to avoid unpleasant inconveniences and installation errors. Their number depends then on the size of the project.
2. Laying operations on site .
Schedule the laying operations on site
As in any business, organizing your workforce and providing them with the necessary equipment requires excellent process and time management skills. Speeding up execution times too much can statistically result in more errors, especially if the work is done in adverse weather conditions.
Therefore, it is very important to set up a monitoring system for the work progress and its collection. To perform this activity, it is suggested to use a control chart as the P.E.R.T. (Program Evaluation and Review Technique) or the Gantt, developed in the 1950s by H. L. Gantt. Both of them list the planned activities, such as site installation, coating, painting, which are then listed in the P.E.R.T., or entered into a two-dimensional diagram that links these activities (columns) to the planned times (rows) in the Gantt.

Avoid potential claims by purchasing quality materials
Purchasing conforming and quality materials is one of the ways to save time and resources. In all works, especially in public ones, such as water or gas networks, it is essential not to compromise the safety of the work and to obtain a good result, not only in the immediate future. It is indeed very important to purchase quality pipes and fitting in order to reduce installation costs.
A common mistake is to link the term “quality” to greater expenses. Actually, buying quality products allows to perform the efficiency in the installation practices without compromising the overall quality of the work.
Keep installation costs down with certified fittings
The purchase of certified and quality fittings can decrease the installation time schedule. This will have a direct effect on the timing of work completion . Investing in properly tested and certified pipes and fittings, made from virgin raw materials, will also decrease the chance of unpleasant inconveniences. Mistakes and breakage could be the start of additional works, refunds and compensation, resulting in a considerable cost increase.

After choosing quality as a guideline, the choice must be made between the technologies currently available on the market, i.e. compression fittings, electrofusion and push-fit fittings. Depending on the needs and the requirements of the project, it is very important to choose the right solutions with the installation time variable in mind. As an example, the push-fit fittings can save up to 17 minutes during the installation process, for each fitting. In the next article we will guide you through the choice of fittings and we will focus on the best solutions for reducing installation time and costs.
