MEMORANDUM <br />To: <br />From: <br />Paul Walters <br />City Manager <br />Raul Godinez II, Executive Director <br />Public Works Agency <br />Date: January 2, 2013 <br />Project Nos. 11 -6736 & 11 -6746 <br />Broadway Rehabilitation: Anahurst PI. to First St. <br />Subject: Change Order No. 2 <br />Contractor: All American Asphalt <br />PO BOX 2229 <br />Corona, CA 92878 <br />Project Description: Broadway Rehabilitation from Anahurst Place to First Street <br />Change Order Number: 2 <br />Accounting Unit - Account - Activity Number: <br />JUSTIFICATION <br />Change Order Total: ($140,000) <br />03017660 - 11673601028 <br />03017660 - 11674601028 <br />The project plans call to cold mill 141,000 SF of existing asphalt pavement (AC) down <br />to existing concrete (PCC), remove PCC, cement treat the base, and then repave with <br />new AC. <br />Subsequent to cold milling, we discovered that the majority of existing PCC is <br />structurally sound and can be used in lieu of the cement treated base, at a significant <br />cost savings. To accommodate this, approximately 40,000 SF of PCC must be cold <br />milled 2" to 4" at a negotiated unit price of $1.25/SF. The $50,000 cost of milling PCC <br />is offset by an estimated cumulative savings of $140,000 from work that is no longer <br />needed which would involve removing all pavement and subgrade preparation for <br />paving. <br />There are two accounts for this project corresponding to different sections of <br />Broadway; Edinger to First Street and Anahurst Place to Edinger. This Change Order <br />encompasses both sections and therefore both accounts. <br />CONTRACT COST SUMMARY <br />Original Contract Total $2,443,348.00 <br />Amount <br />% of Contract <br />Previously Approved CCO <br />$78,010.00 <br />Increase <br />3.2% <br />This Change Order <br />($140,000.00) <br />Decrease <br />-5.7% <br />Total CCO to date <br />($61,990.00) <br />Decrease <br />-2.5% <br />Adjusted Contract Total $2,381,358.00 <br />
