Branford Harbor · Long Island Sound
Status
Completed
Leed Construction replaced three primary weir slide gates at the Town of
Branford's Water Pollution Control Facility — a 4.9 MGD design-
flow treatment plant operating under NPDES permit CT0100048, discharging
to Branford Harbor and Long Island Sound under Connecticut Coastal
Management Act consistency requirements. The plant was never taken
offline. Leed engineered, deployed, and continuously operated a 16-MGD
raw-sewage bypass system with around-the-clock monitoring for the full
duration of demolition and reinstallation, maintaining uninterrupted
treatment and preserving the Town's NPDES compliance posture throughout.
Scope of work included design and mobilization of the temporary bypass
pumping system, coordinated shutdown sequencing of the primary treatment
train, demolition of the three existing weir gates, installation and
alignment of the replacement slide gates, and pressure-testing of each
new gate to a verified watertight seal before returning the train to
service. Effluent quality and permit-limited nitrogen loading to Long
Island Sound were protected for the entire construction period.
Result: A regulated wastewater treatment facility
upgraded with zero loss of treatment capacity, zero NPDES permit
exceedances, and no degradation of Long Island Sound water quality.

West River System · 432,000+ Residents Served
Method
Commercial Dive Ops · 40 Feet Subsurface
Status
Completed
Leed Construction completed the submerged replacement of the reservoir
aeration system at Lake Watrous in Woodbridge, part of the South Central
Connecticut Regional Water Authority's West River supply — one of
four primary reservoir systems supplying more than 80% of the water the
Authority delivers to over 432,000 people across 15 municipalities.
Reservoir aeration is the control measure that prevents thermal
stratification and the resulting water-quality degradation at the
source, upstream of treatment. The reservoir remained in continuous
service for the entire project; at no point was the supply removed from
the Authority's operating portfolio.
Scope of work included commercial dive operations at forty feet of depth
in near-zero visibility to disconnect and recover the legacy airline
network and anchor assemblies, on-site fabrication of 5,000-pound cast-
concrete anchor weights, and diver-executed placement and re-deployment
of the replacement aeration units on the reservoir floor. All work was
sequenced around active raw-water withdrawal to avoid any disturbance to
source-water quality.
Result: Source-water quality control restored across a
reservoir system feeding a public supply of more than 432,000 residents
— executed entirely subsurface, with the reservoir in continuous
service.

Treatment Plant — the Authority's largest facility at 80 MGD rated
capacity, and a direct-filtration plant whose filter basins are the
final treatment barrier before water enters distribution to a system
serving more than 432,000 people. The filtration trains remained in
continuous operation throughout installation; no basin was removed from
service and no reduction in plant output occurred.
Scope of work included engineering and installation of structural steel
mounting assemblies and high-tension safety cable runs providing
continuous engineered fall-arrest coverage across the basin deck. All
anchorage points and cable spans were installed to OSHA fall-protection
standards, with material selection and work sequencing controlled to
prevent any introduction of foreign material into the active drinking-
water basins below.
Result: Permanent OSHA-compliant fall protection
delivered over the active filtration barrier of an 80-MGD treatment
plant, with zero reduction in plant output and zero risk to finished
water quality.

Suspended Water Main Rehabilitation — Quinnipiac River Bridge Crossings, Wallingford
Client
Town of Wallingford Water Division
System Served
14,000+ Customers · 200-Mile Network
Scope
12″ Main Replacement & Rehab · Valves, Couplings & Supports
Status
Zero Downtime · Under Budget
Leed Construction rehabilitated the two water mains suspended beneath the
Church Street (Route 68) and Main Street (Route 150) bridges over the
Quinnipiac River in Yalesville for the Town of Wallingford Water Division
— a utility serving more than 14,000 customers, roughly 88% of the town,
through a 200-mile distribution network. Hung from the underside of two
state-route bridges that together carry about 29,000 vehicles a day, both
crossings are exposed to the weather year-round and depend on their insulation
and hangers to keep the mains from freezing and hold them in line. The Town's
goal was to renew both before deterioration reached the pipe itself.
Scope included site work and replacement of 12-inch water main, valves,
couplings and pipe supports, with zero downtime to the Town’s water
service. Leed rehabilitated 149 linear feet of 12-inch ductile iron main under
Route 150 and 117 linear feet of 8-inch cement-lined cast iron main under
Route 68: stripping the existing insulation, cleaning and applying new
protective coatings, installing 33 new pipe supports and hangers, nine
couplings and six joint glands, and re-insulating both mains in high-density
insulation with a polyethylene jacket, followed by water main disinfection
and testing.
Every task was performed overhead from scaffold platforms built out over the
moving river, in the tight space between the bridge girders. Permits were in
hand before mobilization, the site was run to OSHA standards throughout, and the
work footprint was held tight to protect the trees and sensitive vegetation
along both riverbanks.
Result: Both bridge crossings rehabilitated in about three
months, on schedule and under budget, with the Town rating Leed's
quality control, scheduling, safety and document control at the top score on
its contractor evaluation.

Location
Eastern Point Beach · Groton, CT
Procurement
Public Bid #09-24-24 · Performance & Payment Bonded
Status
Completed
Leed Construction restored the historic exterior of the Zbierski House
for the City of Groton — the three-storey wood-framed house at
Eastern Point Beach, the City's public beach park at the mouth of the
Thames River. Years of shoreline exposure had rotted the building well
beyond its surface: historic trim, railings, columns, decks and
architectural detailing had failed, and the deterioration had reached
the framing and structural members behind them.
Scope of work included removal and replacement of all historic trim,
railings, columns, decks and architectural details, with the decorative
and functional railings of the front porch and second-storey decks
rebuilt to the building's original character. Behind the finishes, Leed
opened up and replaced the rotted framing and structural components
before the new work went back on. The building was completed with new
downspouts matched to the existing profiles, replacement shutters and
new gutters on the storage shed; every exterior surface of the house
and shed was then stripped of existing paint, the stucco spot-primed,
and the whole finished in a peel-stop primer and two coats of
Sherwin-Williams Duration in its existing colours.
Result: The historic exterior of the City's house at
Eastern Point Beach fully restored — every failed trim, railing,
column, deck and architectural detail replaced, its rotted structure
rebuilt, and the building refinished as a bonded public contract for
the City of Groton.

Status
Completed
Leed Construction replaced the wood shingle roof of Cheney Hall for the Town of Manchester and the Cheney Hall Foundation — the 1867 brick performance hall at the heart of Manchester's Cheney Brothers Historic District. Funded through a State of Connecticut DECD grant and designed by Friar Architecture, the project called for a roof true to the building's original character, executed to the Secretary of the Interior's Standards for Historic Rehabilitation.
Leed's own crews stripped and re-roofed the steep mansard slopes, dormers and gables of the landmark, installing new red cedar shingles over a modern protection system — a ventilated cedar breather mat, 30-lb felt underlayment, and self-adhered ice-and-water membrane at the eaves, valleys and dormer intersections. Every course was hand-laid around the building's dormers, cornices and decorative brickwork, preserving the profile and texture of the historic roofline while giving the hall a weather envelope built for decades of service.
Result: A historically faithful cedar roof restored on one of Manchester's signature landmarks, self-performed by Leed and completed on schedule — rated 96 out of 100 in the architect's final contractor evaluation.

Leed Construction executed the complete envelope repointing of Haddam's
early-1800s granite town hall — originally built as a one-room
schoolhouse — for the Town of Haddam. The building sits within the
Haddam Center Historic District, a 267-acre district listed on the
National Register of Historic Places since 1989 and distinguished by its
mid-19th-century institutional buildings of locally quarried granite.
Restoring this envelope preserved one of the district's defining masonry
structures.
Scope of work required months of hand-grinding by Leed's historic-
masonry craftsmen to remove every deteriorated joint without scoring a
single granite face — no mechanical grinding was permitted against
the historic stone. The full envelope was then repointed in a custom
lime-based mortar formulated to replicate the composition, color, and
compressive behavior of the original 19th-century material, ensuring the
mortar remains sacrificial to the granite rather than the reverse.
Result: The complete masonry envelope of a National
Register–district granite landmark restored in period-matched lime
mortar, with zero damage to original stone.

60-foot long-reach excavator, reconstruction of the dam in form-lined
cast-in-place concrete hand-stained to match the original historic
stonework, and integration of the custom eel-pass into the finished
structure. All work was executed under Connecticut DEEP inland water
resources permitting, with erosion and sedimentation controls maintained
throughout in-stream operations.
Result: A historic municipal dam fully reconstructed
with its original stonework appearance preserved, and upstream migratory
fish passage restored to the watercourse.

Occupied Public Housing Reconstruction — Housing Authority of the Town of Stratford
Client
Housing Authority of the Town of Stratford
Portfolio
297 Public Housing Units · 285 Vouchers
Scope
38 Stairs · 10 Occupied Buildings · 2 Complexes
Status
Completed
Leed Construction reconstructed 38 concrete entry-stair structures and
performed associated balcony repairs across 10 residential buildings at
two complexes — the R.E. Baldwin and R.F. Kennedy Apartments
— for the Housing Authority of the Town of Stratford, which
administers 297 public housing units and 285 Housing Choice Vouchers
across the town. Every building remained fully occupied for the entire
project. No resident was relocated and no household lost access to their
home.
Scope of work included demolition of the existing entry-stair
structures, formwork and reinforcement placement, cast-in-place concrete
stair reconstruction, and structural balcony repairs across all 10
buildings. The controlling constraint was access: Leed coordinated daily
with Housing Authority staff and tenant leadership to maintain
continuously safe, code-compliant egress and entry for elderly and
mobility-impaired residents, with temporary access provisions staged
building by building ahead of each demolition sequence.
Result: 38 structural entry stairs reconstructed across
10 occupied public housing buildings with zero resident relocations and
continuous safe access maintained for elderly and mobility-impaired
tenants.

Regulatory
FDA-Regulated · 24/7 Active Facility
Schedule
3-Day Turnarounds × 3 Projects
Leed Construction executed three discrete structural rebuilds inside an
active, 24/7 FDA-regulated food processing facility for Food Tech
International in New Haven — each completed within a three-day
window from mobilization through final cleanup. The facility never
stopped producing. All work was performed under the sanitary and
contamination-control protocols governing an operating FDA-regulated
food plant, and the client did not miss a single shipment across any of
the three projects.
Scope of work on each rebuild included temporary shoring of the existing
roof structure, demolition and reconstruction of load-bearing CMU walls
with steel reinforcement, and re-finishing of the interior and exterior
envelope. All three were delivered entirely on overnight and weekend
shifts, with full containment, dust control, and end-of-shift sanitation
turnover so production lines could restart on schedule each operating
day.
Result: Three load-bearing structural rebuilds
delivered inside a 24/7 FDA-regulated production facility in three-day
windows each — zero production downtime, zero missed shipments.

Excavation · Form-Lined Concrete Wall · Drip-Edge Cap
Status
Completed
Leed Construction designed and built a custom cast-in-place retaining wall for a private hillside property in Middlefield, Connecticut — giving the owner the permanence of structural concrete with the timeless look of a hand-laid stone wall.
Following excavation and preparation of the grade, Leed formed and poured the wall using a specialized architectural form liner that imprints the face with the depth, joint pattern and texture of natural fieldstone. The wall is finished with a cast concrete cap detailed as a drip edge, shedding rainwater clear of the face to protect the finish from staining, freeze-thaw wear and long-term weathering.
Result: A durable, low-maintenance retaining wall that secures the slope, frames the home, and reads as natural stone — adding lasting structural value and curb appeal to the property.
