For each of the two alternatives presented in Chapter-V, a detailed

quant ity take off and .construct ion cos test imate was prepared and itemized

in Tables 5 and 6. Also shown in the tables are the associated unit costs,

engineering, surveying and testing costs, land acquisitions and contingencies.

The unit costs were developed from recent construction bids for projects of

similar nature in addition to WRC experience. A 15% contingency was used due

to the detail of the preliminary design and construction cost estimate.

For the land acquisition costs, only a small portion of the required land

was considered to be purchased. Most of the surrounding land is undeveloped

and the City of Lafayette can obtain the land through the open space dedication

for development or through negotiations. A nominal amount ($25,000 and $30,000)

was included for land acquisitions to cover small parcel acquisitions, admini-

strative costs, or other miscellaneous cost associated with negotiations for

the land.

The Projected Escalation Costs are based upon the Engineering News Record

Construction Cost Index (CCI) for the years 1978 through 1980. Over this 2-year

period, the CCI has increased approximately 17%. The construction of this

project is not anticipated until 1983, which is also a 2-year period and there-

fore the projected escalation is 17%.
