Bollinger, Lach & Associates, Inc. has extensive experience in the design of multi-span highway and railroad bridges for highway and stream crossings. Our designs have included bridges using welded plate girder, rolled beams, and precast prestressed concrete beams. Foundation types include steel H-piles, concrete piles and drilled caissons. Many of our bridge designs have included provisions for staged construction along with temporary sheeting and cofferdams. Our retaining wall experience includes conventional cast in place concrete walls, concrete faced soldier pile walls with ground anchors and proprietary block wall systems. Bollinger, Lach & Associates, Inc. has designed multi-cell cast in place concrete culverts, precast culverts and various underground concrete chambers. Our broad range of experience allows us to provide responsive, innovative and on schedule design solutions that can be adapted to the special needs of each project. In addition to design we also offer extensive experience in field inspection and rehabilitation of existing structures.
