Concrete Bridge and Rubble Masonry Concrete Weir for Emergency Spillway

RMC Weir: Teichmann Structures has constructed Liberia’s longest Rubble Masonry Concrete structure to date. Comprising of three arches, each over 70 meters long. The 2.5 meters high, 5.5 meters wide and 250 meters long RMC structure is the longest ever constructed in Liberia and possibly West Africa. It was built as part of the Mount Coffee Hydro Electric Rehabilitation Project intended to maximise labour intensive methods of construction in order to assist with alleviating poverty and promoting the upliftment of local people in the post civil war Liberia recovery process.

220m Concrete Bridge: Teichmann Structures once again successfully combined a hybrid construction system of merging precast concrete elements with insitu concrete to reduce the construction duration for major civil structures. Teichmann Structures manufactured and installed 112 precast concrete beams each measuring 14 meters in length and combined these with 15 Insitu concrete Piers that were each 6 meters high. 2 abutments and 16 deck spans together with other elements such as sidewalks, handrails, lighting and drainage resulted in a 220 meter long concrete bridge being constructed in just 8 months.
