Project Complications & Achievements
Due to the existing ground conditions throughout the crossings, it was not possible to achieve the specified compaction of the Type 2.3 material. Due to rain events, the crossings had constant surface & subsurface flows making it difficult to achieve the specified compaction. As such, Shamrock Civil Engineering proposed to replace the Type 2.3 material (in both Type 3 and Type 4 crossings) with a rock layer (75mm nominal rock), 150mm thick.
