Welcome to our website. Our consultancy is based in Lake Mary, Florida (USA) and provides professional engineering services to bridge owners, designers and constructors.
Our services include independent design reviews, forensic engineering and expert advice on complex bridges, bridge construction machines and their interactions. Design reviews include supporting and challenging bridge owners and design-build teams for competitive pre- and post-award designs of modern bridges.
We also provide customized training on modern bridge design and construction technology. Training includes books, eManuals, face-to-face courses and a Bridge Club hosting a rich collection of exclusive articles and free publications. We are also working on a 60-hour on-line course that will be available worldwide in a few months.
Our key opinion leader services include a Newsletter that reaches bridge owners, designers and construction professionals in every corner of the world, 19.000 followers in LinkedIn, and a Bridge Construction Technology group with 6000 members.
In 36 years of professional activity, I have been working in 21 countries on the design, design review, construction and forensic engineering of complex bridges and bridge construction machines.
My background includes 14 cable-stayed bridges, 9 arch bridges, 24 launched bridges, 11 balanced cantilever bridges, 4.9km of bridges cast span-by-span with MSS, 24.8km of high-speed railway bridges, and 72.8km of precast segmental bridges.
My assignments also include 2 self-launching gantries, 6 movable scaffolding systems (MSS), 2 span carriers with underbridge, 2 portal cranes, casting facilities for 23 launched bridges, 16 falsework systems and some form travelers.
My first book Launched Bridges (1998, ASCE Press) sold out almost immediately.
Bridge Launching (2002, Thomas Telford) and its second edition (2014, ICE Publishing) are the international references for the design and construction of launched bridges.
The bestseller Bridge Construction Equipment (2013, ICE Publishing) is the reference title for mechanized bridge construction and the design review and forensic engineering of bridge construction machines.
Three book chapters and a hundred of publications and lectures are additional contributions.

Marco Rosignoli's ability of merging field work with research and innovation makes his books and courses precious to the international bridge community.
John Stanton, PhD, PE, Professor of Civil Engineering, University of Washington (USA)
I regard Marco Rosignoli not only as a worldwide-renowned expert, but in fact THE world authority, in the field of bridge launching.
Fritz Leonhardt, Prof.Em., Dr.Ing., Leonhardt, Andrä und Partners (Germany)
Your book Launched Bridges is the most complete presentation of this construction method. I congratulate you for this work.
the eManuals Project
The Bridge Engineering eManuals Project promotes knowledge and learning of modern bridge design and construction technology. The eManuals can be downloaded in PDF format from this website and as Kindle Editions from Amazon.
In less than two years, bridge owners, designers and construction professionals have downloaded eManuals from 39 countries on five continents to master the business-driving arena of the bridge industry and stay ahead of the game with clients, competitors and colleagues.
The project is growing rapidly and now includes 17 titles, a rich collection of exclusive articles and free publications, and a Newsletter reaching thousands of bridge professionals in every corner of the world.
Large-scale bridge projects are constructed with highly mechanized methods. Cost and limited availability of skilled labor and tight construction schedules dictate massive investment in special equipment to mechanize and accelerate the construction of large structural members and minimize...
eManuals: In-Place Casting
In industrialized countries with limited availability of expensive skilled labor, medium-length prestressed-concrete bridges are cast in-place with special equipment to mechanize and accelerate construction and minimize labor demand and the construction cost of the bridge. The efficient use of form...
eManuals: Incremental Launching
Why are the launched bridges so competitive? Well, it all about cost and quality. The construction cost of a bridge deck includes materials and technology (labor and investment in special equipment). Compared with incremental launching, in-place casting on falsework leads to higher labor costs with...

The research and practical work of Marco Rosignoli have been enormously influential in diffusing the use of the incremental launching method in Europe.
Clifford L. Freyermuth, Executive Vice President, ASBI, American Segmental Bridge Institute (USA)
Dr. Rosignoli's training and experience make him a world authority in the incremental launching of concrete bridges.
Roberto Capozucca, Prof.Ing., Dr.Ing., Professor of Structural Engineering, Universita’ Politecnica delle Marche (Italy)
Marco Rosignoli has proposed new analysis and design methods, new technological solutions, innovative construction techniques... Marco Rosignoli is making the history of the incremental launching method.
Decades of cooperation with ACI, ASBI, ASCE, IABSE, ICE and PCI, my 4-year term as founding chair of IABSE working group WG-6 Bridge Construction Equipment, and so many years of professional practice have generated a unique wealth of knowledge, learning and insights.
The courses that I teach for the ASCE Continuing Education Program and face-to-face in the offices of bridge owners, designers and constructors are true learning experiences to train bridge teams in modern bridge design and construction technology while meeting continuing education objectives.
Mechanized Bridge Construction
Beam launchers and shifters are used in many countries for construction of precast beam bridges. Self-launching gantries and lifting frames are used for span-by-span and balanced cantilever construction of precast segmental bridges. Movable scaffolding systems (MSS) are used for span-by-span and...
With extensive illustrations and case studies, this 16-hour course provides exhaustive coverage of the design, construction, technology and industry trends of steel and prestressed-concrete bridges built by incremental launching.You will learn under which circumstances is...
Precast Segmental Bridges
This 8-hour course provides exhaustive coverage of span-by-span and balanced cantilever construction of precast segmental bridges. With extensive illustrations and case studies, the course explores the geometric design of precast segmental bridges, the production of standardized atypical...
Movable Scaffolding Systems
The course explores the use of movable scaffolding systems (MSS) for span-by-span and balanced cantilever casting of prestressed-concrete bridges. You will learn under which circumstances is span-by-span casting with MSS a competitive alternative to incremental launching and precast segmental...

Excellent seminar, Marco is an expert on the subject. (Mechanized Bridge Construction, 2 days)
Angela Hunter, Design Engineer, Kiewit Infrastructure Co. (USA)
This course was an excellent introduction to bridge launching. Did a great job of showing when it is cost-effective or applicable, and showing alternates. Also great teaching on technical aspects and design principles. (Launched Bridges, 2 days)
Timothy Hayes, Senior Project Manager, Walsh Construction (USA)
Great overview and resource to stimulate thought when selecting bridge type. (Launched Bridges, 2 days)

Ahead of the game !
Bridge Owners make construction technology decisions for design-bid-build projects and score the construction methods of design-build proposals. Bridge Designers explore modern construction technology throughout the process from teaming interview and value-engineering to the post-award design. Bridge Constructors increase win rate and profitability and mitigate risk with new technology that saves costs and improves safety and quality.
The bridge industry is moving toward mechanized construction, and the Bridge Engineering eManuals Project promotes knowledge and learning in the business-driving arena of the industry.
Books, eManuals, courses and the articles and free publications of the Bridge Club provide a unique wealth of knowledge, learning and insights for your firm, agency and professional career.
