. � 1 <br /> G3IGROUP <br /> � <br /> STRUCTURE MONITORING PROGRAM <br /> It is recommended that the ewsting structure be closely monitored for future potentially adverse <br /> settlement. Should future subsurface settlement result in adverse structure distortion (such as <br /> cracking), additional structure stabilization is expected to be warranted. In this regard, it is <br /> recommended that the walls be monitored by installing a series of crack monitors and/or vertical ! '� <br /> survey points along the walls. Areas in which the movement of the walls is considered excessive may ; ', <br /> be further supported with the use of a deep foundation system, as previously described. ' <br /> FLOOR SLAB , <br /> The floor slab is not considered to be a structural member. In this regard, repair of the floor slab is ' I <br /> typically not considered as critical as overhead members. 'However, the displacement of the floor ' <br /> slab due to settlement may be aesthetically disruptive and create tripping hazards. Movement of floor <br />'� slabs within the building interiors tends to be marginal due to low moisture variations. <br /> � <br /> Polyurethane foam may be applied to fill voids which have developed below the e�sting structure <br />� floor slab and re-level the floor slab. Polyurethane consists of specialized foam having well-defined <br /> expansion characteristics that may also be injected below the concrete slab using small-diameter ' <br />, holes. The expansion of the polyurethane allows the unrestrained concrete to be lifted to the <br /> preferred floor level. Following injection, the polyurethane solidifies as a rigid form and will not <br /> l� change shape. <br /> The floor stabilization is not considered a one-time solution to voids underlying the concrete slab, but <br /> should be anticipated to require multiple applications. This process tends to require re-application as <br /> the subsurface soils intrinsically settle. , <br /> Pier Parameters <br />� Calculations of pierdepth, pressures were obtained from input of the results of the soil boring into <br />� HelixPro foundation software. A rint out of this anal sis can be seen in the attachment. <br /> P Y <br />'� <br /> � <br /> � <br /> I <br /> I, <br /> Florida Office: Phone: 727.376.7833 Tennessee Office: <br /> 2410 Success Drive, Suite 7 Fa�c: 727-376-2758 45 Oak Valley Drive ; <br />� Odessa, FL 33556 Email:info(��eo3�roup.com Spring Hill,TN 37174 i <br />, Web: www.�eo3�roup.com I <br />
