A complete Construction Site mission guide covering the walkthrough, deployment order, rewards, completion regions, equipment planning and common mission problems.
This DrainSim Construction Site guide explains the full mission walkthrough, recommended deployment strategy, completion regions, rewards, equipment planning and troubleshooting for the current game build.
Reroute incoming street water towards lower-elevation drains and protect excavation pits. Use the mission data below to check the reward, measured regions, infrastructure and target time before choosing your loadout.
Reroute incoming street water towards lower-elevation drains and protect excavation pits.
Deployment order: Bring a heavy but organised loadout: multiple buckets, shovel, barriers, pumps, generators and cleanup tools. Open the upper drains before the excavation pits become the only available storage.
Reduce the volume reaching the excavation before it spreads across the site.
Use trenches and dirt placement to steer water instead of trying to block every inflow.
Keep excavation regions from becoming permanent reservoirs.
Close all eleven regions after the major flows are controlled.
Watch a complete Construction Site play guide demonstrating one effective route through the mission. Equipment behaviour, timings or mission mechanics may change between DrainSim updates.
Follow the mission walkthrough in this guide: establish water control first, work through each measured completion region in order, then finish shallow water and recheck the cleared areas before ending the mission.
Construction Site has 11 completion regions that must be cleared before the mission can finish.
The base mission reward is 3,500.
Start with the deployment order shown in the Mission Briefing. Secure the main drainage or discharge route before spreading equipment across the rest of the map.
