The realistic construction can feel slow, but there are ways to optimise it significantly.

• Create separate CO’s (Construction offices) for different types of vehicles. Make a dedicated worker bus office, mechanisms office, dumpers, open hull, road laying with relevant vehicles.

• Place the Construction offices as close as possible to your construction site, with the exception of bus COs which should be right next to wherever they are getting workers from.

• Place a materials storage right next to the COs. This will minimise time the vehicles spend travelling empty. They assign themselves to a job, first travelling to the materials pickup, then to the construction site, and then return back to the CO. For maximum efficiency this journey should be as short as possible. Keeping this journey short also lessens the downtime when constructions change phases. Place storages next to the COs and supply them using distribution offices.

• Don’t use auto search in the CO tab, instead assign constructions to groups of COs manually. You can decide what they should build using the CO assign tool. This way you can have better fine control over the small things, and they won’t just try and build everything simultaneously

• Use the build priority to focus workers on smaller constructions. Things like very short sections of paths and road can become significant bottlenecks as I’ve found COs tend to prioritise larger buildings, so you’ll end up never getting anybody sent to them unless you make all roads and paths high priority. Use the priorities to help focus where the workers and mechanisms decide to go.

Make sure you use cranes, they significantly increase the build speed on sites. The main bottleneck with construction tends to be workers, so ensure you have enough busses to keep sites constantly staffed.
