Tectonic Engineering is excited to share our FDR Park Wetlands Mitigation Project Update The FDR Park 29-Acre Tidal Wetland (Park) site is in the final phase of plant growth for the thousands of trees, shrubs and grasses that sprouted up in 2024 and transformed this construction site into a green lush site. Also, this site continues to receive the high tide from the Navy Yard and the Delaware River as designed and constructed which promotes wildlife habitat and alleviates the flooding which use to hamper the Park’s operation. The City of Philadelphia, local, state and the federal environmental agencies value the enhancements that this project has created. The residents enjoy the wildlife and the scenic view as they walk around the perimeter of the wetland. The property making up the Philadelphia International Airport (PHL) contains areas of jurisdictional wetlands and waterways subject to federal and state regulation. Tectonic was contracted to provide Construction Management and Inspection services in support of the overall plans to develop a viable wetlands mitigation area to compensate for impacts of proposed and future development of the Philadelphia International Airport. This Project consists of constructing a 29-acre tidal wetland mitigation site at FDR Park. The Work includes: 1. Temporary haul road construction 2. Excavation of a 29-acre tidal wetland basin 3. Testing, sorting, and handling of excavated materials 4. Constructing a soil hill with fill excavated on-site and disposing of residual waste materials in accordance with applicable laws and regulations 5. Retrofitting two historic 3-foot by 6-foot brick arch culverts with tide gate structures 6. Wetland, meadow, and turf seeding 7. Minor grading adjustments for wetland establishment 8. Planting plugs and containerized plants 9. Supplemental seeding for wetland establishment 10. Monitoring and adaptive management plan to ensure site establishment 11. Non-native invasive plant control 12. Removal of haul road and associated sediment controls and fencing. Project challenges included residual soil material testing and handling, working in an active community park, and procuring over 44,000 trees, shrubs, plugs and other vegetation. Congratulations to the team and Tectonic's PA Regional Director Bernard Rohe, PE, MCE, CCM, PMP for a job well done!

Our Teston Sluice Refurbishment project has recently received 45/45 in a recent Considerate Constructors Scheme (CCS) audit. The work we are carrying out on the Teston Sluice Refurbishment project will restore the gate, built in 1974, which is in a state of mechanical and electrical deterioration resulting in a risk of failure to the structure's operation. The project aims to enhance the natural, historic, and built environment and provide safe access all year round to the lock site as well as protect the community from the risk of flooding. The CCS report highlights the site team’s efforts to care for the environment, with a wide range of environmental plans in place and all flood protection plans deliver compliance with VolkerStevin’s net zero corporate commitment for 2030. The site team also has regular briefings on wildlife, endangered species and identification of invasive species. The report also praises the team’s dedication to leave a lasting, positive impact on the community. Throughout the duration of the project, the team has been proactive in engaging with the public, visiting local schools to talk about the career opportunities available in construction, welcoming work experience students to site and undertaking litter picks in the local area. Congratulations to the Teston team!

?? San Cristóbal de La Laguna City Council is making progress in restoring its former wetland, and we're excited to share the latest developments! ??The City Council has taken a significant step by putting out a tender for a hydrogeological study to restore the former #wetland that gave the city its name. This study will be fundamental to understanding the dynamics of ground and surface water in the area, which will allow for the design of effective strategies for wetland restoration. ?? In order for the old La Laguna wetland to see the light again, a highly precise technical deployment is required: ?? #Hydrological and hydrogeological studies of the area ?? #Cartography, #precipitation #climatic data ?? Estimation of #infiltration to the #aquifer ?? Inventory of #water points (e.g., springs, wells, galleries) ?? Mapping water flows such as ravines, ditches and irrigation channels, springs and spillways. ?? All this information will allow us to update a conceptual hydrogeological model of the Vega Lagunera, and thus, establish predictive scenarios to optimize the park's design and evaluate its performance under extreme conditions. To do this, we will simulate different alternatives, such as: ?? Extreme scenario of high precipitation ?? Extreme #drought scenario ??? Possible changes in the position of the drains and in the base topography of the wetland. The hydrogeological study was put up for tender in July, valued at 72,905 euros, with a four-month execution period. Its aim is to analyze the park's viability as part of a #Green Infrastructure Plan, addressing #sustainable #urban #drainage management through controlled #flooding. ?? In September, work began to determine the terrain's morphology and extract the preliminary data necessary to carry out the technical study. Additionally to this first survey, three more similar were performed at different points, using machinery capable of drilling up to 10 meters deep and extracting the deposited material, which will help to precisely define the characteristics of the subsoil.??? The surveys will allow us to know the lithography of the terrain, data necessary to perform the study of the hydrogeological model that will determine the levels of the wetland bottom when maintaining a fixed water level throughout the year, and to see at what level we have the basalt to lay the foundation for possible structures, walkways or bridges. The next step ?? Conducting the hydrogeology study, which will be awarded by the public company Gestur-Canarias. ??

We are pleased to share a very special video featuring a channel & watercourse reconstruction project we completed in Orangeville, Ontario. Natural Channel Design (NCD) is a specialized approach to watercourse restoration and realignment which attempts to reconstruct channels to emulate the natural physical form of the river or stream features that would be appropriate for that location. There were several sensitive environmental constraints that had to be managed during the design and construction of the project, including: *Removal of an existing pond to maximize developable area for the site and its’ natural environment *Re-connection upstream & downstream of the Mill Creek Tributary *Passage of native fish through both the existing tributary and new channel *Settlement of fine particles and their affect on water quality *Flood relief and floodplain storage for larger rain events A few unique engineering features included: *Implementation of natural erosion controls through plantings at channel banks, seeding & erosion blankets *Implementation of the channels’ meandering shape and rifles / pool systems to protect the channel bed *Aeration and cooling the water *Energy dissipation to support aquatic habitat Hebster Construction is extremely proud to have been part of this incredible team of planners, surveyors, designers, and specialized consulting engineers. With their hard work and support, our crews collaborated to execute and deliver this critical piece of infrastructure, providing critical habitat to the natural environment. In collaboration with the Town of Orangeville and all those involved, the project was a huge success! A huge thanks to Dan Gallo for showcasing our work through this incredible video. #Crozier #GeoMorphix #SchollenandCompanyInc #dgaerialimagery #branding #innovation #construction

Check out a great discussion in the comment that pulls heaps of knowledge I learned from my PhD study with my mentor alumni! #WSUD #root #stormwater #mentoring
Engineer | Advancing sustainable stormwater management for infrastructure | Founder - Australian Drainage Engineering Community (ADEC)
WSUD Crew....I've been investigating infiltration systems recently and came across some rather ominous text in the City of Moreton Bay Design Guidelines - Stormwater: "Approximately 50% of infiltration trenches partially or totally fail in the first five years after construction (Galli, 1992)". ?? ??♀? ?? This is a fairly old reference so I'm curious to see whether people feel this statistic would still ring true today. Have our design, installation, or maintenance practices improved to change this? ? Do any of my WSUD or geo friends have any good experiences to share or lessons learned? Bonus points if they're Queensland examples ?? #infiltration #InfiltrationBasin #InfiltrationTrench #drainage #WSUD #WaterQuality
