Every project has that one item. The architect drew a hexagonal planter box. The MEP consultant designed a strange U-shaped cable trench. The landscape designer wants a curved bench.

Your site team looks at the drawing and groans. “How are we going to formwork this?”

The Problem with On-Site Customization

Attempting to build complex shapes on site using plywood and nails usually results in:

  1. Poor Finish: Wood leaves grain marks and joints. Curves are never true curves; they are just a series of flat angles.
  2. High Waste: You cut a 4x8 sheet of plywood to get a small curve, and throw the rest away.
  3. Time Sink: Your best carpenters spend 3 days building one box, instead of working on the main structure.

The Solution: Steel Fabrication

At Precision Precast, we don’t just pour concrete. We have an in-house Steel Fabrication Workshop.

When you send us a drawing for a “weird” shape:

  1. We 3D Model it: To check for clashes and reinforcement spacing.
  2. We Build a Steel Mold: Laser-cut steel plates, welded to 0.5mm tolerance.
  3. We Cast it: Using high-slump, self-compacting concrete (SCC) to fill every corner.
  4. The Result: A glass-smooth finish, perfect curves, and identical dimensions every time.

When to Outsource

  • Quantity < 5: Probably cheaper to do on site (if quality doesn’t matter).
  • Quantity > 10: Definitely cheaper to Precast. The cost of the mold is amortized over the units.
  • Architectural Finish: ALWAYS Precast. You cannot get a “Fair Face” finish with site plywood.

Don’t let a tricky detail slow down your site. Let us mold it.
