The Marsh Creek Road Eridge will be constructed in an area of gently rolling terrain wiih minor vegetation except for scattered trees.. The bridge site is likely underlain by alluvial materials which in turn are underlain by sandstone of the Joaquin Ridge Formation. At the time of our site visit, a narrc-Y,r two-lame steel bridge was used to cross the creek. Based on the expected Foonddi ion cunditions in the proposed bridge locations and the anticipated bridge loads, we recommend the following scope of work for each of our foundation investigations: I .

Design recommendations for bridge excavations and backfill . Our services would be provided in accordance with the rates and :elms shown on our standard fee schedule a copy of which is printed on the reverse side of the last page of this proposal . We estimate that the cost of our foundation study for the Marsh Creek Road Bridge will range between $2,800 and $3,2CG and We would not exceed the latter amount without your prior approval . Because of the uncertcir:ty of the sub- surface conditions at the Park Avenue site, the costs of our foundation invest- cation for this bridge could vary considerably. If alluvial-type materials are encountered and the drilling of the exploratory borings goes reasonably well , then we ` estimate that our cash v✓bold be betr een $2,400 and $2,700. However; if boulders,. and rocks are encountered resulting in difficult drilling, our costs could rise to between $3,200 and $3,600. We should note that this esiinicte assumes than Contra Costa County will supply the locations of all underground utilities in proposed 'boring I ocations and will secure any necessary access permits. f, ! s s s ! w.., od r � b` Our pr.,,:SSlbna, Cr`.'Ii.e� ��C!� .,c p�rforrii�. , our in is lilt$ v ,alnGa and 0::. r�i:0i�u:�iendatiOnS prepared in accordance with generally accepted 'engineering principles and practices.
