Crusher Run Question


Dear all, first post and question please

Situation: I'm currently supervising the construction of a Building-Intergrated PhotoVoltaic (BIPV). The idea is construct a steel structure (just like factories) without the rooftop. The rooftop will then be replaced with solar panels instead. This BIPV is within 100m of the sea. Steel structure is about 80m x 90m x 6m.

Problem: This steel structure is currently being built on seaside soil. Water ponding and heavy machinery entry is a huge problem. Hence, laterite + crusher run is needed (total 450mm height) to support 20 tonne cranes etc. Total area for crusher run is about 0.8acres. But this is really expensive and costs $33,000 USD.

Question: Are there any other cheaper alternatives? THANK YOU.


Tldr; New structure on seaside soil, crusher run cost is a killer. Any alternatives?

Re: Crusher Run Question


hello pappagor, thanks for the suggestion. actually, how do i lay this breaker run?

at the moment im sitting on a quotation for 300mm of Laterite, topped with 150mm of Crusher run. i see that breaker run looks great for soft subsoil.

Mud/crane mats. Large timbers bolted together that will span sloppy/wet soils. Might take more than one layer but they work wonders. You can rent them here in the us, not sure about in your location.

Re: Crusher Run Question


Cancel the solar baloney, Use the $ saved to pour concrete pipe pilings under the steel columns. Install drainage tile to mean sea level fill over with the crushed rock/concrete. Steel tracked heavy equipment requires embedded rails to protect the concrete surface over time.

Let some silly competitor waste money on the part time power that is solar now. Stick with a 24/7/365 power source. Worst case use your mobile generator set(s) as back up power, if local grid unreliable, A ship/barge mounted power plant would several times cheaper than any pie in the sky solar cell pipe dream.

Ask the solar cell maker if will work after a typhoon?

Steel structure 100 meters from the sea, as in salt water? Even if it's hot dipped galvanized good luck!
