Expertise

Our Company Expertise

We are committed to site specic, creative, and cost-eective solutions for our projects. We provide comprehensive civil engineering services, from initial feasibility and master planning through design, permitting, and construction support. Our civil engineers take pride in developing strong relationships with our clients and teaming partners.
Civil engineering is not all about fancy buildings – it is about maintain- ing vital infrastructure.
Yawson and Lombardi provides consulting on development proposals,
Whether it is a complex design for a separated highway or a simple pe- destrian bridge abutment, Yawson and Lombardi will determine and ex- ecute the most suitable construction approach catered to your priorities.
Our versatile structural engineering design experience in bridges, box culverts, walls, piers, and foundations mean our solutions match the goals of the project. We take great strides in bridging gaps in community mobility, solving stormwater infrastructure problems, and supporting building design teams. Yawson and Lombardi geotechnical Engineers supplement our structural designs by analyzing slope stability, evaluat- ing soil compaction, and recommending foundations for any subsurface condition.
Yawson and Lombardi has produced detailed design engineering for all manner of oshore marine transportation and installation operations, from jackets and topsides through to FPSO moorings and modular plants. These solutions have been delivered using a range of marine eet, from tugs and barges to DP construction vessels, heavy lift ships and module carriers. Longitude has even developed vessels for oat over operations and decommissioning operations.
Our services cover all design phases and all disciplines. Each project is planned according to the client’s needs and preferences. Whether the outcome should be a full classication design or a feasibility study, we pay special attention to careful project planning.
Our earthquake engineering team provides seismic hazard analysis for infrastructure and mining projects.
We apply a unique, reliability-based approach to the seismic design of dams, mine waste facilities, process plants, power plants, tunnels, port structures, and many other types of constructions subjected to seismic hazard.
Yawson and Lombardi provides exploration to evaluate soil, rock, and underground water. We analyze and interpret this information to pro- vide the client with an appropriate design that accounts for unforeseen issues beneath the surface.
Our geotechnical engineers have the knowledge and experience to pre- pare geotechnical reports for various types of geotechnical analysis and design, including foundations, walls, structures, subsurface drainage, and pavement. We also conduct any necessary geophysical surveys uti- lizing seismic testing, resistivity testing, sonic testing, magnetic testing, ground penetrating radar, or thermography.
