2  Anything “structural” – change in loading, structural capacity, pile locations  If in doubt, call us! See Structures Contacts Handout BOS Contacts.doc  Remind Contractor to go thru Construction Staff for answers

3  CMM 1-65 Updated engineer responsibilities related to as- built structure plans (require “STRUCTURE” to be placed above as-built title box on title sheet)  CMM 5-70 Guidance and checklist for field personnel inspecting ancillary structures installations (mainly pertain to new sign/signal structures installation requirements)

4  Std. Spec. 501.3.8.2 (FDM and CMM Guidance will be available in March 2015)  New Policies Dual Approach to Ice Based on Project Type  Projects with HPC or greater than 2000 CY concrete STSP 501.1000.S shall be included in plans and bid by contractors  Projects with less than 2000 CY concrete Standard spec administrative item payment of $0.75/lb remains in affect  Ice should be paid for – field engineers should not delay pours if ice is required  Ice delivered and stored on site should not be paid for unless used as required per Std. Spec.
