and two meetings with library staff to better <br />understand the functions of the Library. Following <br />these meetings, on October 10, 1989, <br />Midyette/Seieroe presented a proposed schematic <br />design of the new library to the Library Advisory <br />Committee. <br />During the committee meeting, estimates for cost of <br />the design as prepared by Midyette/Seieroe and <br />Fischer Construction indicated to interior <br />renovation of the building could be accomplished for <br />slightly under $100,000 (the present budgeted amount <br />for construction). However, the interior renovation <br />would not provide the new library exterior with a <br />sense of entry. The architect has suggested various <br />exterior additions to the building to provide a <br />better sense of entry, as well as a location for a <br />central elevator. The construction cost estimates <br />of the exterior additions are approximately $33,000 <br />and an additional $30,000 for a new elevator. <br />During the design, two separate studies have been <br />performed to determine the structural adequacy of <br />the 2nd floor of the structure to support a new <br />library occupancy. The first study performed by <br />Johnson-Voiland-Archuleta for Midyette/Seieroe <br />under the terms of the agreement for design of the <br />library indicated the walls and foundations <br />sufficient to support the additional load provided <br />a 2,200 psf allowable soil bearing pressure could be <br />confirmed. The second floor joists, I-beams and <br />columns however were not sufficient for the <br />additional load. <br />Upon receipt of the first engineering study, <br />Construction Services retained the services of ATEC <br />and Associates to investigate the allowable bearing <br />pressures. The results of the second study <br />determined two things: 1) the footings actually <br />installed during construction were 2 ~~ - 4'~ wider <br />than indicated on the original plans for the <br />building. This is significant in that it increases <br />the area of footings to spread the load and would <br />have the effect of lowering the required load limit <br />determined in the Johnson-Voiland-Archuleta study; <br />and 2) the soils were determined to have a 2,500 psf <br />allowable load capacity. <br />Therefore, the structural upgrading required is <br />limited to adding additional floor joists and <br />strengthening of the 2nd floor columns and beams. <br />Construction Services estimates the cost of <br />structural upgrading to be slightly less than <br />$10,000.
