Mr. Radcliffe has prepared designs for repair and/or new construction in timber, steel, concrete, and stone masonry, private homeowners, municipalities, and government agencies. Mr. Radcliffe has been involved in the underwater inspection and assessment of conditions at Mystic Pier No. 1 in Charlestown, MA and participated in the design of repairs and preparation of contract documents. He served as the resident engineer during construction of this $5.6 million project, at the time, the largest single contract for piling rehabilitation in the United States. Mr. Radcliffe received his Master of Science in geotechnical engineering from Northeastern University in 1991. Since that time, Mr. Radcliffe has been lead engineer in charge of the geotechnical aspects in projects requiring that form of expertise. Rebeca Porter Skalaski, Structural Engineer Ms. Porter brings a background in resident engineering services to Childs Engineering Corporation. Ms. Porter has served as a field engineer on various projects in the metropolitan Boston Harbor area. She has been a field engineer responsible for providing layout and survey of all activities on-site.

Ms. Porter oversaw the project build-out, approved submittals, prepared requisitions for payment, prepared and tracked project costs and verified payroll reports. Ms. Porter has also served as resident engineer in Virginia and Connecticut. While in these two areas, she performed quantity take-off, collected bid quotes from both vendors and subcontracts, and estimated time and labor for construction activities. Childs Engineering Corporation has put Ms. Porter’s experience to work at job sites throughout New England. Most recently, she has served as resident engineer for the rehabilitation of piers and rampways at Long and Central Wharf. Robert J. Welch, Engineer / Diver Since joining Childs Engineering Corporation, Mr. Welch has performed over 150 underwater inspections of marine structures such as; piers, wharves, bulkheads, seawalls, relieving platforms (100 ft penetration dives), bridge abutments and piers, caissons, wave attenuators, fender systems, marine railways, graving docks, floating dry docks, canals, and culverts. The inspections have included both destructive and non-destructive testing methods and photo documentation of observed conditions. Mr. Welch has performed inspections in Canada, Iceland, Spain, Japan, and all along the eastern seaboard of the United States. In addition to his inspection responsibilities, Mr. Welch has been involved in the design of new structures and the rehabilitation of existing structures for clients in both the public and private sectors. Mr. Welch has experience in all aspects of the structure rehabilitation process starting with the initial topside and underwater inspection, providing structural assessment and repair recommendations to the client in report format, design of repairs, project cost estimation, production of design plans and specifications, obtaining permits, and concluding with construction supervision as a resident engineer. Mr. Welch has also calculated bridge load ratings and bridge inventory ratings based on structural conditions noted from bridge inspections. Philip Iantosca, Jr., Engineer / Diver Mr. Iantosca brings to Childs Engineering Corporation his extensive diving experience and Civil Engineering training.
