Info

The USACE estimate for construction management in Reach B is nearly three times higher than the SAFCA estimate. Given the availability of actual costs for this activity covering most of the construction work in this reach, the basis for this difference is unclear. 14
3.2.9 Summary – Reach B When totaled, the cost estimates for each of the project accounts described above result in the USACE estimate for the NED Plan being approximately $76 million higher than the SAFCA estimate for the 200-year project in Reach B. The USACE estimates for lands and damages, levee and floodwall construction, and construction management account for the majority of this difference. Tables 2A and 2B provide a detailed comparison of the costs of the SAFCA 200-year project and the USACE NED Plan in this reach.
