<br />Eugene City Hall Complex Master Plan
<br />Additional Cost Summary
<br />
<br />This following cost summary shows initial project costs, utilities and maintenance costs for 50
<br />years, average land costs within downtown Eugene, demolition costs for the existing building
<br />(demolition for other sites depends on the site selected), and relocation costs. Additional infor-
<br />mation on the composition of the utility and maintenance costs follows this table.

<br />Assumptions
<br />All options accommodate 300,000 gross square feet of building area.
<br />(a) Project costs include initial construction cost and 1.35 soft cost multiplier.
<br />(b) Includes energy, water, and sewer costs for 50 years adjusted to 2006 dollars. Renovation
<br />options include energy, water, and sewer costs for the renovation and a companion building.
<br />(c) Includes building operations and major maintenance costs for 50 years. Renovation options
<br />include operations and major maintenance costs for the renovation and a companion building.
<br />(d) Market value for downtown land ranges from $30-38 per square foot. Values above reflect
<br />average cost of $35 per square foot. Renovation options include a half block to accommodate
<br />companion building; New 1 option assumes purchasing a full block; New 2 option assumes
<br />purchasing a half block. Hybrid and New options are not offset by potential sale of existing
<br />building and/or site.
<br />(e) Demolition costs will depend on the existing improvements and constraints surrounding the
<br />selected site. Sites that have substantial existing structures or have adjacent buildings on mul-
<br />tiple sides will have higher demolition costs. Renovation options may require demolition costs
<br />for the companion building site; Hybrid options will require the demolition of some or most of
<br />the existing building; New options will be site dependent.
<br />(f) All options will require at least one move. Renovation and Hybrid options will require two
<br />moves (to a temporary location during construction and back when the project is complete).
<br />Relocation costs include $2.50/square foot for moving and $2/square foot/month to lease space
<br />for 18 months. Total costs for options N1 and N2 do not include multiple relocation costs. If
<br />the existing City Hall site is used for new construction, total costs would increase by
<br />$2,695,000.
<br />
<br />Utilities and Maintenance Cost Summary
<br />The estimated life cycle costs associated with energy, water, sewer, and ongoing building mainte-
<br />nance are presented in Table 2 for each of the six primary options. Estimated average initial pro-
<br />ject cost is also shown, in order to provide an order-of-magnitude comparison between the life
<br />cycle operating costs and anticipated first cost. In general, the new options are expected to exhibit
<br />the lowest operating costs while the hybrid options exhibit the highest. Total operating costs are
<br />expected to vary by about 12% from most expensive to least expensive. Utilities costs, while not a
