From Lamond-Riggs Library Friends

Lamond-Riggs Library construction progress update 4/15/2021:

·  All (151) deep foundation piers have been completed.

·  Construction equipment for deep foundations has been demobilized

·  Post deep foundation site re-grade is complete.

·  Offsite Steel fabrication is complete.

·  Temporary utility coordination is underway.

·  As you may recall, from design presentations, the large (Bradford pear) tree closest to the building informed the design concept and the footprint of the new building. As shown in the design phase diagram below, this tree was intended to remain and was safeguarded during demolition. Following the removal of the building, the previously hidden root structure has been under evaluation by Arborist, Urban Forestry, & DDOT and unfortunately as of this week, they all agreed that the tree is a safety hazard and needs to be removed. 

o In consultation with DDOT, an expedited tree removal permit has been filed.

o A distinct mature tree is planned to be transplanted in the proximity of the old tree to keep the design intent intact.

o The exact location and species for the new replacement tree are under consideration and will become clear following ongoing consultation with Urban Forestry & DDOT. 

What to expect in the weeks ahead?

• Construction will continue within the permitted hours of 7:00 AM to 7:00 PM Monday through Saturday.
