Eric / Clay, The request for additional days is based on the over run of piers / casing and the addition of scope to the job. After a detailed review of the changes I believe the original request of 35+ days is a little heavy and think the below listed increase is more accurate: 1) Piers – 14 calendar days (total $ increase related - $ 100,000) 2) Electrical – 7 calendar days (actual / realistic install time of additions) 3) Irrigation & Utility Adds – 5 Calendar days - (actual / realistic install time of additions) 4) All other adds / deducts are basically a wash Total revised days request for CO # 4 – 26 Calendar Days.
