Dear Clients & Friends,
We are excited to share an announcement with you! This week, Robert Derector Associates Consulting Engineers finalized an agreement to acquire SIA Acoustics. This will allow us to offer acoustical design and consulting in addition to our full range of MEP engineering services. Sam Berkow, the founder and lead consultant of SIA Acoustics, will be joining RDA as a principal.
Many of our clients have requested acoustical consulting as part of our in-house services. After a long search for the right provider, we are thrilled that we can now offer MEP, telecommunications, multimedia, and acoustical engineering services, all under one roof. This acquisition will allow RDA to respond more effectively to our clients' needs. We expect that the added efficiency will serve to streamline project schedules, simplify procurement, and improve coordination.
Sam and his team bring a wealth of experience in acoustical science, engineering, and design. From installing new systems in stadiums, concert halls and top recording studios to controlling noise in office environments and telecommunication centers, SIA Acoustics’ projects represent the highest standard of quality. Until our new website is updated, please visit SIA’s website where you can explore examples of their outstanding work.
We are looking forward to collaborating with Sam and the SIA team, and all of you, as we begin this new chapter at RDA. Please get in touch if our team can be of service, or if you have any questions.
