Many projects require the input of construction professionals to achieve the most economical and practical design for a particular project. H.B. Fleming has the construction knowledge and the technical ability to help customers find reasonable solutions to challenging projects.
On many projects H.B. Fleming will collaborate with the customer's engineer to develop a design which uses material and construction techniques most suitable to the project's needs. On other projects H.B. Fleming has completely designed and constructed the project, thus providing a fast track and economical solution to a particular problem.
A steel sheet pile retaining wall was constructed in this situation because the excavation required for construction of a conventional retaining wall would have encroached on abutting property. This type of retaining wall eliminated the excavation that would have destroyed trees on the abutting property owner's land.
A.B. Chance helical tieback anchors were augered into the underlying soils and then pre-loaded to prevent deflection of the wall.
A.B. Chance anchors work on the principle of distributing passive soil resistance to successive helixes. The torque required to auger the anchor into the soil can be translated to tensile capacity. The ultimate capacity of the anchor can then be verified by load testing.
In a similar situation steel H-pile and timber lagging are used for a retaining wall next to an existing highway.
Chance anchors are being installed with an hydraulic auger to stabilize an existing concrete retaining wall.
In this situation, water from the lake was undermining an existing dam creating an unstable situation. Steel sheet pile was driven deep below the existing dam to cut off the flow of water. The void between the dam and the sheets was then filled with concrete to add mass to the structure.
In an effort to preserve the historic architecture of this library; architects planned an addition that was below grade and adjoining the existing building.
H.B. Fleming designed an excavation support system that transferred the weight of the existing building to steel H-pile and then retained the soil under the building with timber lagging. This system resulted in zero movement of the existing structure during the evasive construction of the new addition.
In many cases customers want to construct bridges that serve a specific transportation need on their property. H.B. Fleming has customized many bridges to customers' needs utilizing innovative materials and construction methods.
This bridge was designed to fit into the natural environment and still carry HS-20 vehicle loads.
This bridge was designed for heavy industrial loads and with sheet pile abutments to prevent scour and undermining.
