What are they building on Busch

<p>If you have visited there recently, you might have noticed that there is an orange net circumscribing a portion of area in front of the broken red rectangular statue (don't know how else to describe it) near SERC and also in the field between ARC and Library of Science and Medicine. It looks like they're building something, but they don't have any recognizable form that might give me a slightest idea of what they are.</p>

<p>Do you know if they're building something, or repairing? Last year they were adding pipes underground by serc and by lsm, maybe they're still doing that.</p>
