This document describes 48 educational projects implemented for 1971 under Title III of the Elementary and Secondary Education Act. The goal of Title III is to stimulate new and improved educational practices and to determine their effectiveness. Wisconsin E.S.E.A. funds were designated for 4 major areas: (1) innovative programs, (2) establishment of educational centers, (3) special educational programs, and (4) guidance, counseling, and testing.

It is not often that there is an opportunity to obtain a detailed and overlapping record of ground displacements; that is, heave during excavation and settlement during and subsequent to building construction. This paper presents such a case record and describes briefly site stratigraphy, the instrumentation used, the data obtained, and its analysis. The structures in question are the 34 storey Alberta Government Telephones building and the adjacent 28 storey Oxford building, together comprising the A.G.T./Oxford Complex, located in downtown Edmonton.Heave points were embedded below the base of the 300 × 300 × 45 ft (91 × 91 × 13.7 m) deep A.G.T. excavation in over-consolidated soil. Their elevations were read several times during the phased 1-year excavation period, each time accompanied by measurement of the excavation dimensions. To January, 1972 2.5 years of settlement have been recorded from readings taken on more than 100 basement column plugs. In addition, visual observations were made, construction loading and piezometric data were obtained and laboratory soil tests were undertaken. Analysis of the data was initiated in an effort to gain a better understanding of the mechanisms governing the response of these over-consolidated soils to both loading and unloading.Heave response within the excavation area was found to be rapid and computable by elastic theory. Much of the heave occurred during excavation. The time dependent portion virtually ceased 2-3 months subsequent to cessation of excavation. The amount occurring at adjacent structures outside the excavation was less than that predicted from elastic theory. Analysis of settlement data indicates that during construction settlements are rapid at footing pressures less than the original overburden pressure and can be predicted using elastic theory. Subsequent settlement at higher footing contact pressures also occurs rapidly, but with a stress dependent modulus of deformation. In general, the moduli derived from laboratory test specimens were found to be unsuitable and unreliable. Several conclusions of importance to construction practice and foundation design are drawn relative to proximity effects and phasing of excavation and building construction. Il est rare d'avoir la possibilite de reunir des observations detaillees et concurrentes de deformation du sol, en soulevement durant l'excavation et en tassement pendant et apres la construction de l'edifice sur un meme site. L'article presente un cas type de ce genre et decrit la stratigraphie du site, l'instrumentation utilisee, les observations faites et leur interpretation. Les structures en question sont l'edifice de 34 etages des Alberta Government Telephones et l'Edifice Oxford adjacent de 28 etages, formant le complexe A.G.T./Oxford dans le centre ville d'Edmonton.Des points de controle du soulevement ont ete installes sous le fond de l'excavation de 300 × 300 × 45 pi. (91 × 91 × 13.7 m) de profondeur de l'edifice A.G.T. dans un sol sur-consolide. Leurs elevations ont ete prises a plusieurs epoques durant les differentes phases de la periode d'excavation qui a dure un an chaque mesure etant accompagnee d'un releve des dimensions de l'excavation. Ensuite et jusqu'en janvier 1972 des releves de tas... Language: en

Historians of the Chicago School of architecture, and they are fast becoming a crowd, have been consistently unaware of the fact that caisson foundations,' a most satisfactory solution for heavy buildings on poor soil, were pioneered not in Chicago in 1893 but in Kansas City, Missouri, in 1890. Chicago rightfully lays claim to giving birth to the steel-framed office tower. That extraordinary structural revolution took place in the Loop, where the wet silt and deep-reaching soft clay made foundations a matter of paramount concern. It is noteworthy that H. H. Richardson, at work in Chicago on his great Marshall Field Wholesale Store (1885-1887), called on John Wellborn Root to discuss soil and foundation problems, Root having led the Chicago architects in using raft foundations of steel rails imbedded in concrete.2 The use of caissons for achieving stable foundations for buildings of any height or weight, by sinking the piers to hardpan clay or bedrock, evolved slowly in Chicago. Caissons were not in use in Chicago at the time of Burnhamn & Root's magnificent Monadnock Block (1889-1891), which, over the years, has settled more than 20 inches,3 or the huge Auditorium (1887-1889) by Adler & Sullivan, the tower of which has settled more than two feet.4 Of the Auditorium foundations and the trials
