NEI handled the architectural and structural renovation design for this residential property on Riverside Dr. in Tiverton, RI. The project focused on a comprehensive interior redesign combined with structural upgrades to modernize the home. A key element of the new interior layout is the vaulted ceilings which create an open, airy atmosphere throughout the living spaces.

The renovation also featured a complete overhaul of the home's exterior aesthetic, highlighted by a new elevated roof deck designed to maximize the property's water views.

NEI recently completed the design, CRMC / Army Corps permitting and installation of this new wastewater discharge pipe at Blount Fine Foods in Warren, RI.

The project replaced an existing 80' steel discharge pipe from the 1970s that remained in use after the facility was updated for seafood processing, which had become heavily degraded with numerous holes.

The infrastructure was redesigned as a seamless high-density polyethylene (HDPE) pipe equipped with a diffuser system. Now fully installed, this updated system extends the treated effluent discharge near the midpoint of the river to enable more effective diffusion and long-term reliability.

Construction progress continues at 62 Aquidneck Ave in Portsmouth, RI. Framing is currently underway following the completion of the foundation, pier system and septic installations. NEI was fully responsible for the comprehensive architectural and site design of this coastal project.

While the property is situated right outside of a high-hazard flood zone, the design incorporates proactive structural engineering to address long-term environmental risks. The structure utilizes a highly resilient pier and grade beam system designed to protect the building as coastal threats evolve. Unlike conventional foundation walls, this engineering approach features specialized "breakaway" panels intended to be sacrificial, allowing high-velocity floodwaters to pass through safely beneath the structure, complemented by integrated flood vents for lower-yield storm events.

We're pleased to see the final completion of this multi-year coastal project in Portsmouth, RI. Working alongside the owners' New Hampshire-based architects, our team provided local engineering support, including the full site survey, CRMC permitting, OWTS design and structural engineering.

Because both the main house and studio sit within a flood zone, the project required a full pier foundation design with breakaway walls. Also, the owners built and lived in the studio first before completing the main house, a roof deck and a bio-retention system for stormwater management.

It's great to see this project officially wrapped up, the sunset views from the new roof deck are epic!

Congrats to for graduating from Roger Williams with a (second) masters, now in public administration. I'm so impressed by your overachieving and finishing this up after having Koen!

We recently wrapped up this seawall maintenance project in the heart of Island Park - Portsmouth, RI. The transformation balances long-term stability with environmental care, replacing a failing, unpermitted wall with a fully compliant installation. By connecting rebar reinforcement in the slab to an upslope retaining structure, we’ve ensured this project will stand the test of time against the elements.

Even though seawalls are often a challenge for the environment, this specific design actually results in a net decrease in impervious area. We reduced the size of the patio and added intentional landscaping to help the site breathe. The finished slab features a beautiful pebble texture and a new recessed fire pit, making it the perfect spot to enjoy the stunning views of the Sakonnet.

Huge thanks to Atlantic Lawn and Garden out of Jamestown, Rhode Island for the expert site work!

🔧 Big work happening underground in downtown Providence!

Our team is on-site monitoring the installation of 16" waterline line stops, a critical and complex operation in an aging urban water system. These fittings allow sections of the waterline to be isolated and shut off without disrupting the broader network, which is no small feat when you're working within the layered infrastructure of a historic downtown area.

This work is part of a larger effort to relocate utilities along Adrian Hall Way, making room for an exciting transformation – Trinity Repertory Company's building expansion, a new pedestrian plaza and a park space, all while preserving the existing skatepark. It's a tight fit underground but our crews are making it happen.

NEI is proud to be part of bringing this vision to life, one pipe at a time!

Stay tuned, watch this space. 🚧

A huge congratulations to Irina Perespelista! Irina is wrapping up her first two weeks as a Senior Civil Engineer with NEI and has already given us a major reason to celebrate by passing her PE exam. We are so proud of her hard work and look forward to seeing her officially licensed in the very near future.

Welcome to the team, Irina!

We're proud to share a recent pro bono project completed for our neighbors here in Portsmouth. Our team at NEI created this new Beach and Waterfront Access Map for the Common Fence Point Association (CFPA).

We're always willing to donate our time and expertise to help promote public coastal access in our community. This durable vinyl sign will soon be posted at the CFPA Hall and available online for residents and visitors. 🌊🗺️

We're excited to share this marina reconfiguration project at West Wind Marina on Waites Wharf. The existing layout dates back to the 1990s, a time when the Navy controlled the waters seaward of the marina, resulting in a design that's become an awkward and difficult entry for modern navigation.

With control of these waters reverting to the City of Newport in 2014, we're happy to help redesign the marina for safer, more logical navigation.

Working on behalf of the owner, we've successfully navigated the municipal approval process with the Newport Waterfront Commission and the CRMC. Army Corps approval is currently pending.

No construction date is set yet, but we look forward to seeing this improved infrastructure take shape in Newport Harbor.

✅ Safety: A complete reconfiguration to correct the entry angle and improve navigation safety.

✅ Community: Installation of new kayak racks specifically for city residents.

✅ Shoreline: Improvements to the surrounding coastal features.
