Peter informed me that he had no objection to the proposed amendment except that he wanted to delete the weekly construction meetings which were proposed at the construction kickoff meeting. I have therefore, prepared a revised contract amendment which is attached for your review. The amendment contains three elements: a review of the project schedule; a proposed fee increase for design services; and a proposed fee increase for construction services. As background in support of the amendment, we offer the following information. Schedule Our contract called for a design phase lasting for twelve weeks. At the eleven week point,we delivered"pre-final"plans and specifications for review. Due to decisions made by the City which were beyond HNTB's control,the design work was suspended for a period of approximately fifteen months. The design work resumed in November 1995 and was completed in late December. Based on the original design schedule, construction was expected to commence in November of 1994 and be completed by December of 1995. The current schedule submitted by the tank contractor, CBI Na-Con, indicates substantial completion occurring in May 1997. Design After our submittal of pre-final plans on September 2, 1994, we worked occasionally on design alternatives to install a motor operator on an existing valve at the Airlite Water Plant. This work was performed at the City's request, but was not part of the original design scope. HNTB inspected the site and made field measurements to the surrounding area, prepared preliminary drawings and cost estimates for four alternatives and submitted several letters summarizing our findings. After sorting through several options involving excavation and yard piping changes at the Airlite Plant, HNTB ultimately located a compact body actuator and disconnect which could be installed on the existing valve in the existing vault. The estimated savings represented by this solution in comparison to other alternatives is $6,000. This work began in October 1994 and continued through August 1995. ] he 1/ l TB (. nm/ a n I \• \i.i.

The effect of this delay is that HNTB's direct costs (such as salary, overhead, and expenses) have risen from the original construction fee. The scope of construction services in the original contract is based on a work plan identical to the construction services provided for the Shales Parkway Tank construction project. There has been no change in scope for construction services, on this project. Based on the effect of a 16-month delay on direct costs, the revised cost of construction phase services is as follows: CONSTRUCTION SERVICES SUMMARY A. Periodic Construction Review 1.
