Construction office uses manual labour, instread of 3 bulldozers

[itapple53]

When I want to build gravel road, сonstruction office uses only workers, It has 3 bulldozer and 3 flatbed trucks, which are staying and doing nothing. Bulldozers were used to build gravel roads, but only these which are really near to CO, but not these, which are a little far. What am I doing wrong

Short road sections don't use machines. Maybe this is the cause?

How long should the road be, so CO would use bulldozers?

At least two shortest node distances long. For pathways it seems shorter than for roads. In construction window, there should me vehicle slot shown or not, if you want to assign workers only to roads that won't get picked up by bulldozers.

When you click on the road or footpath which you want to build, and you see an empty small box, then you don't need workers. In the box the bulldozer or excavator will appear once delivered.

I'm not sure about that.
If I remember correctly I have seen pieces of footpath with less demand of Gravel using machinery.

2t footpath can take machinery and is over 2 node distances long. 0.78t path, notdividable, cant use machines. Maybe it isn't a rule, but that lenght is pretty good indication.

Yes footpath is much less, but he was talking about roads and it is +7t of gravel needs to be used minimum for machinery use

It needs workers when it shows road work signs at both ends

On another issue with road construction, is that roads should not be blocked creating a planning nightmare. During construction, roads are not closed, they have one lane available. At least it should be an option, as of now it is not practical to use CO for roads unless you double all the roads.

On the construction office dialog, make sure you check the box to deliver equipment by truck. If you don't, the CO will sometimes send excavators and cranes by themselves, which can take forever if the construction project is far away. They travel very slowly.
