PW�3�OfiQ�301iG390 The proposed amendment will allow Baird, Ha.mpton & Brown, Inc., to provide adc�itionai engi- neeriug �ervices on the pro}ect due to the fallowing: Subseqnent to award of the constr�action contract, the Water Depaztment requested that the pro- �osed water and sewer lines located at the s�uth end af the ai�port be e�tended further to the south in order to provide waste and sewer serv�ice FQr fi�ture customers. In addition, since a utility contra�or is aIready on sit�, staff is af the opinion that it is financially beaeficial to the City to e�end t�e water and sewer tines in conjunction with the current cQxtstzuction project. The amendment will also a.11ow the consultant to provide several exhibits needed by the Water Departm�nt to develop the per acre charge for the of%site saniiary sewer extension invalved with th'ss praject. Baird, Hampton & Brown, Inc. has snl�mitted a proposal in the amount of $6,718_04 far the addi- tianal services �o be provided thereby increasing the contract fee fiom $181,866.a0 to $188,584.00. I believe t.his fee is fair and reasanable for the additional services.
