How does the use of own means affect the score?
Look, in this public tenders, having their own means is like getting to a party with your own DJ, lights and open bar: everyone looks at you differently. When we talk about our own means, it is basically what a company has at home —machinarian, personal, offices, trucks ... whatever - and can start it without asking anyone. That, for those who score these competitions, is usually a tip. It shows that you control the cotarro, that you will not be waiting for you to rent a crane or that the electrician appears. Less trouble, less delays. Nobody likes drama, right?
Public administrations, which are usually quite boring, value it a lot. They see that you have your own means and think: "Well, they seem solvents and they will not vanish at the first change." And yes, many times that translates into more points for you. Especially if what they ask is technical quality. There it does differentiate to teach muscle, with photos of your machines, curriculum of your people, and all that. The more detailed you put it in the proposal, the better. That the level is noticed, but without going out of flipado, of course.
Now, you don't believe that just by having your own means you will win the tender. I hope it was so easy. The price, the deadlines, the previous experience and the quality of what you offer also weigh a lot. So, nothing to trust you. You have to curre a balanced proposal, which not only says "I have everything I", but also convenient on other sides.
In short, yes, pulling your own means can give you advantage and add points, but it is not the only thing. You have to play all the cards well. And if you can boast resources, do it, but without forgetting the rest. In the end, winning a tender is like flirting: it is not enough to go well dressed, you also have to have conversation.
