Dewatering induced settlement of a historic landmark

Laefer, Debra F. ; Frazier, Jon ; Evans, Ashely (ASV Publishers, 2003-09)

Construction related dewatering in urban areas often induces damage of existing structures. The following forensic investigation highlights the complexities of such a phenomenon. Somerset plantation, a national historic ...
New possibilities for damage prediction from tunnel subsidence using aerial LiDAR data

Laefer, Debra F. ; Hinks, Tommy ; Carr, Hamish (2010-06)

Computation modelling has not been fully exploited for predicting building damage due to tunnel-induced subsidence, because of the expense and time required to create computational meshes for the vast quantity of buildings ...
Opportunities and impediments to the use of 3D laser scanning for adjacent excavations

Laefer, Debra F. ; Carr, Hamish ; Morrish, Sean ; Kalkan, Erol (American Society of Civil Engineering (ASCE), 2006-02)

Although three-dimensional laser (3DLS) scanning has been used to document and monitor individual excavation walls and structures on a limited basis, impediments remain to its use for major infrastructure projects. This ...
Performance expectations for microcrystalline waxes for the seismic protection of art objects

Crowley, Anne ; Laefer, Debra F. (Getty Publications, 2006-05)

Use of microcrystalline waxes for the protection of ceramic art objects from seismic events is an inexpensive and relatively popular technique in museum exhibition practice (Fig. 1). Unfortunately, because of the high ...
Predicted tunnel-induced settlement and damage to Findlaters church with respect to freefield and constructed side considerations

Murphy, J. ; Gaynor, S. ; Laefer, Debra F. (2010-02)

Dublin, Ireland is scheduled to constructing its first metro in 2010, with a pair of tunnels connecting the city center to the airport. This study presents first-order predictions of the anticipated soil settlement and ...
Predicting reinforced concrete frame response to excavation induced settlement

Laefer, Debra F. ; Ceribasi, Seyit ; Long, James H. ; Cording, Edward J. (American Society of Civil Engineering (ASCE), 2009-11)

In many tunneling and excavation projects, free-field vertical ground movements have been used to predict subsidence and empirical limits have been employed to evaluate risk. Validity of such approaches given the reality ...
Unexplained blasting vulnerabilities in a historic town

Laefer, Debra F. ; Loughlin, B. ; Hickey, S. ; O'Farrell, S. ; O'Mahony, G. (2008-07)

Historic residential and commercial structures in an early twentieth century town in the southeastern United States have regularly and repeatedly been damaged by an adjacent quarry, despite the diligent keeping of blasting ...
