Project Performance
Helping Clients Fulfill and Exceed Expectations through Performance Optimization
Perhaps more than any other sector, dredging and marine construction offers infinite opportunities to save (or lose) vast sums of capital. Experience on both sides of the equation, Project Engineer and Contractor, is required to realize the greatest savings. On complex interdisciplinary dredging and marine construction projects, Lally LLC stands apart in its ability to locate opportunities, optimize efficiency, and minimize project risks.
We have found significant improvement opportunities, from tender phase through construction, generally falling into technical (i.e. project engineering design, equipment selection and methods), operational (i.e. effective time, management) and contractual areas. Having worked on over 1,000 dredging and marine construction projects as engineer, owners’ representative and contractor, Lally delivers field-proven consultancy services on numerous types of dredging projects and equipment.

Successful dredging and marine construction projects require significant preparation. Experience shows thorough and accurate site characterization studies are required in order to achieve optimal project performance.
Lally LLC offers a range of site data acquisition, analysis, and visualization services to define physical properties, bathymetry and environmental conditions. We conduct digital soil mapping and workability windows analyses in order to select best equipment approaches and develop accurate production and cost estimates.
These services can be completed through site reconnaissance and field investigations, as well as desk studies, to bring needed clarity during the planning and bid phases.

- Quality of Life (e.g. Sound, Light) Monitoring
- Rapid Post-Dredge and Placement Survey Mapping for Acceptance Determinations
Whether performing monitoring activities on site or remotely, we can set up alarms that trigger at pre-set metrics (e.g. permit-stipulated NTUs, offshore dredged material placement boundaries), in order to rapidly inform necessary operational changes.
Lally LLC has monitored critical dredging performance on projects across sixteen 16 Time Zones (e.g. East Coast Standard Time – New Zealand Standard Time) and effectively motivated improvements to save clients tens of millions of dollars employing these methods.
Of benefit in dredge and marine construction project optimization efforts, but also at times later in claims matters and litigation, Lally LLC has developed the niche field of Dredging Forensics TM, whereby numerous equipment and project data sets are acquired, processed, synthesized and analyzed to determine hindcast performance and event information.
This unique offering takes different formats depending on several factors, is experience-based, and has proven to assist in resolving unknowns to save clients in excess of $100 million.
Our forensic analyses and hindcast tools have also proven valuable to contractors and project owners wanting to understand past performance more closely when tendering on recurring or similar project sites. We are knowledgeable in acquiring access to numerous public maritime databases and prior project results and maintain a significant repository of marine equipment and project databases.
