- Pump truck setup. Make sure there is a nice level pad for the pump/outriggers.
- Route for concrete trucks. Are you going to get two side by side, or one at a time?
- Wash out bins. Set up where they will be out of the way of incoming trucks and preferably so the concrete trucks don't have to waste time with a ten point turnaround to get to them.
- Lights. If placing during the dark, make sure you have adequate lighting.
- Spacing. Set your concrete trucks to what your site can handle. Yes the pump capacity and your manpower could handle a hundred yards an hour. However, if you can only accommodate one truck to the pump at a time and it takes 2 minutes for the truck to pull up and away from the pump. Considering you would want to set your spacing to 60 yards an hour, thats 5 minutes to dump out and 5 minutes to guide the truck's in and out.
- Placment. If you have deep footings you might not need as many finishers as if you had shallow but wide footings.
- Consolidation. How many vibrators are needed to stay up with the pump and finishers. If you have 20 shallow footings, you might want to have 4 vibrators to place the concrete quickly.
- Coordination. If you have a tight site and need to place 500 yards before traffic becomes a burden, you might decide to man up for greater output. Additionally bringing extra manpower to turn trucks in and out as quickly as possible. They can scrape chutes, flag and stage all of these will help save time.
- Placing. The key to a quick placement is making sure the truck spacing, consolidation and finishing in sequence with each other. If you have one or another fall behind it could set off a domino effect; trucks waiting and stiffening up , causing extra time to consolidate a hot load and increasing manpower needed to finish the pour without losing it. By informing your crews the placement plan: pump size, truck route, spacing, quantity etc.. they will grasp your expecatations and play their part.
With a solid logisitics plan, appropriate size pad/pump , spacing on concrete trucks (placing as quickly as possible without overwhelming the finishers or consolidation crew), right amount of manpower; flagging trucks to the pump, place and finish the concrete. You can create a placment flow where you make money, not stess out workers and leave the owner with a quality product.
