Project 2 – CEI Bonner Bridge Replacement
Marc Basnight Bridge Phase 2 Construction North Carolina Department of Transportation, Outer Banks, NC

Description

The new 2.8 mile long Marc Basnight Bridge replaced the Herbert C. Bonner Bridge, and was built using first-of-their-kind design and construction methods to provide a 100-year service life, resist unprecedented scour depths and minimize environmental impacts while offering a reliable, safe passageway to and from Hatteras Island. The new structure is designed to resist wind, wave and vessel collision forces from the worst storms in the Atlantic Ocean, while subject to unprecedented scour depths. The foundation design includes driven, pre-stressed concrete piles for the long spans as well as the approach and transition spans. To address the concern of how to drive large displacement piles through dense sand, the NCDOT team developed innovative jetting installation methods, leading to the extensive use of refined soil-structure interaction analyses. This project also includes demolition of most of the old Bonner Bridge, while preserving and modifying the northernmost segment for pedestrian use. Following is a progress video compiled near the end of the construction of the new bridge:

Project 3 – San Francisco Public Utilities Commission Bioregional Habitat Restoration Program

Project Summary

Ms. Teri Beckett, PE, GC, QSD and Arborist, served as Project Construction Manager on the San Francisco Public Utilities Commission Bioregional Habitat Restoration Peninsula Program.

The ten (10) active BHR sites throughout the SFPUC jurisdictional area provide ecological mitigation benefits to offset environmental/habitat impacts resulting from Water System Improvement Program (WSIP) construction projects. Within the Peninsula Region, Ms. Beckett managed the CM team on the WD-2641R Project Series, which included the Homestead Pond Mitigation, Adobe Gulch Grasslands, and San Andreas Reservoir wetlands construction. Each of the sites contained the following project elements: demolition, selective clearing and disposal of invasive exotic vegetation; grading to tight tolerances for wetland construction, installation of pedestrian walkways, installation of native seed stock utilizing hydroseeding techniques, and extremely tight SWPPP controls. Ms. Beckett managed a team that provided conventional construction management as well environmental compliance support to SFPUC involving the implementation of CEQA mitigation measures addressed in project EIRs and Mitigated Negative Declarations, as specified in the CEQA-compliant Mitigation Monitoring and Report Programs (MMRP), or agency permit conditions. These include conditions specified in California Department of Fish and Game Section 1601 Streambed Alteration Agreements, San Francisco Regional Water Quality Control Board Section 401 Permits, U.S. Army Corps of Engineers Section 404 Permits, and special-status species protection specifications under the federal Endangered Species Act and California Endangered Species Act. From time to time, the construction projects required minor project deviations that may or may not have been adequately covered in the CEQA project description or environmental analysis that led to either an EIR or Mitigated Negative Declaration. In such cases, the CM Team performed CEQA-level analysis, conducted field studies related to wildlife, plants, special-status species, wetlands, or cultural resources, and assisted with preparation of documentation for submittal and approval by San Francisco Planning Department or, as required, the appropriate federal or State resource agency.

This project included California red-legged frog, San Francisco garter snake, San Francisco dusty-footed wood rat, and Mission blue butterfly habitat, with Ms. Beckett managing a series of biologists performing pre-construction surveys for nesting birds, raptors and special-status wildlife, plants and fish species, and their habitats. The Project Construction Manager duties for this project included design of conceptual Erosion Control Plans for each site, and inspecting BMP installation of the erosion control materials throughout.

Project Performance

  • The Environmental Compliance team managed by Teri Beckett was able to oversee construction in an extremely ecologically sensitive area within compliance of the large variety of permit conditions governing operations.
  • The team observed certain areas that required some level of redesign, brought these scenarios to the attention of BEM while recommending redesign of plant mixes and construction methodology to better replicate surrounding native conditions.
  • The team was able to provide significant support and mapping recommendations during the seed collection operations just prior to installation of native vegetation.

Major construction occurred in protected animal and botanical species habitat with extremely low disturbance level of either. This was accomplished by performing stringent botanical and species pre- and during- construction surveys to avoid areas with a higher likelihood of species presence, as well as strict construction oversight.

Project 5 – C-111 Project 7 – USACE Southern Everglades Region

Description

The project consisted of levee construction and degrading, construction of water control structures for the SFWMD. Project value: $7,000,000.

Scope of Services

SKS Engineering and Planning, Inc. drafted the Environmental Protection, the Manatee and Eastern Indigo Snake, Migratory Bird Protection as well as the Storm Water Pollution Prevention Plans. In addition, SKS also filed the National Pollutant Discharge Elimination System (NPDES) Notice of Intent (NOI) for the project and for all modifications. All documents were approved by USACE Southern District personnel in first draft form, with no corrections required. SKS Engineering also provided water quality, snake, and manatee monitoring and reporting services for the project. SKS Engineering was primarily responsible to coordinate these and other environmental permit compliance issues with the USACE and FDEP as a contractor representative. Migratory birds that fall under the protection of the Florida Endangered and Threatened Species Act of 1977 were discovered within the final levee to be degraded. The contractor adjusted his sequence of operations to avoid impacting the nesting activity, and conducted a more detailed presence-absence survey of the area than that required by the specifications to ensure that no nests would be disturbed. The water quality report deliverables provided to the USACE by SKS for this project were described as “impeccable,” and “raising the bar,” by the USACE Program Manager, with some discussion as to whether samples of these reports could be incorporated into future contract documents issued by the Corps. SKS Engineering operated as a subconsultant to the construction contractor, Atlantic Civil, Inc., acting as their representative when coordinating with regulatory and environmental agencies on environmental compliance issues.

Date

Project was completed in January of 2009.

Project 6 – Jewfish Creek Bridge Construction

Client:  Florida DOT – District VI
Title:  US 1 / Jewfish Creek Bridge Const.
Cost:  $300,000,000
Duration:  6 Years, completed

Sandwiched between the Atlantic Ocean and Everglades National Park, U.S. 1 is the main roadway from the mainland to the Florida Keys. The project was constructed in a very environmentally sensitive habitat, as it had Everglades National Park, the Crocodile Lakes National Wildlife Refuge, the Southern Everglades Region, and other areas which are designated as Outstanding Florida Waters as its boundaries. The project included construction of a mile long bridge over Lake Surprise and Jewfish Creek, in addition to 21 miles of roadway over and through protected wetlands including mangrove forests and seagrass beds. The permit and therefore project requirements included:

  • extremely strict water quality requirements, and phased, multiple extensive Storm Water Pollution Prevention Plans with hurricane provisions;
  • mangrove, seagrass and native upland tree protection issues, including arborist-supervised mangrove and other native tree trimming, and vegetation identification and marking for the purpose of impact avoidance. The project included unavoidable impacts to over 40 acres of mangrove and seagrass habitat;
  • protection of Federal and State regulated species such as manatees, American crocodiles, sea turtles, etc.  Manatee signage, monitoring, and erosion control structure selection to avoid endangering these and other protected species were all mandated within the US-1 Project permits;
  • bird monitoring and protection measures, including Osprey nest relocation at the initiation of the project. 

SKS Engineering Scope of Services

SKS Staff were responsible for overseeing construction compliance with environmental permits. Other compliance issues include endangered species and vegetation plans and protective measures, contractor education, coordination with environmental agencies. Duties also included environmental agency coordination and regulatory inspections, subaquatic surveys including seagrass impacts and debris field inspections, wildlife protection monitoring, drafted and provided environmental education programs, maintained regulatory compliance documentation including Permit Requirement trackers, and processed all permit reporting requirements, and drafted regular inspection reports. Formal contractor training sessions were held including open discussions of animal and vegetative species that are protected within the permits, as well as how to handle encounters with such. Regulatory personnel were invited and participated in the forum. SKS services also included turbidity testing and reporting, erosion control structure inspection and “on-the-fly” revision recommendations.

SKS performed review of contractor SWPPP and other plan submittals, inspection and certification of dewatering, excavation, Maintenance of Traffic, erosion control systems; evaluation of the contractor schedules, shop drawings and field practices against regulatory requirements, inspection documentation and reporting.

Project 7 – Upper Keys Pre-Mitigation

Client:  Florida DOT – District VI
Title:  US 1/Jewfish Creek Bridge Pre-Mitigation
Cost:  $7,100,000
Duration:  3 Years

This 7.1 million dollar pre-mitigation for Jewfish Creek Bridge was constructed eight years prior, and was the largest such project performed by FDOT – serving to restore numerous sites within the Crocodile Lakes Refuge and Everglades Region. SKS performed resident engineering services as the on-site Resident Engineer, including supervision of a large team of biologists, engineers, office staff and Contractors; contract administration and inspection, as well as environmental agency interface. Water quality, endangered species and vegetation, design / permit modifications “on the fly” and prohibitive site conditions were all part of this highly successful project.

This 7.1 Million project was spread out over a 50 mile perimeter in the Northern Florida Keys, completed in the late 1990’s, originally included clearing and grubbing of exotic vegetation, with adherence to strict permit regulations regarding the identification and preservation of small pockets of protected vegetation, chipping and mulching with seed source dispersal controls. Over 17 miles of turbidity containment structures were installed throughout the sites, to comply with the sometimes zero levels over background requirements included in the permits. Also included was the scraping down of varying types of existing material to tightly controlled elevations, the creation of tree islands and fish refugias in a freshwater emergent area, and the removal and replanting of over 5,000 protected hardwoods. As CEI Resident Engineer, Ms. Beckett made numerous design and permit modifications. The changes included: 1) modified elevations at the C-109 Canal and US‑1 Roadside Spoil Sites to more closely replicate surrounding natural features; 2) developed detailed planting schedules for the C‑109 tree islands to match tree groupings on existing islands in the basin; 3) added new mitigation areas at US‑1 Roadside Spoil to better improve sheet flow in the C‑111 basin; 4) added flushing channels throughout the Harrison Tract to improve flushing to planting areas; 5) included mangrove propagule planting at Harrison to further the FDOT’s two year coverage goals; 6) modified construction method details to better facilitate work in the sensitive areas in and around the construction sites. Her duties as on‑site Project Resident Engineer also included supervision of the large CEI team including biologists, engineers, office staff and Contractors; contract administration, construction inspection, environmental agency interface with the SFWMD, USFWS, FWFGC, ACOE, DERM, and the FDEP. Regular progress meetings and site inspections with the FDOT, their consultants, and environmental agency representatives were held and documented.

Project 8 – Birch State Park Restoration

Client:  Broward County Aviation Department
Title:  HT Birch State Rec Area, Ft. Lauderdale
Cost:  $2,100,000
Duration:  14 months.

This 43-acre project was constructed in one of the world’s most popular tourist areas, Fort Lauderdale Beach. It consisted of selective clearing, native tree relocation, excavation to create tidal channels, open pools and mudflats to optimize habitat value, planting of native vegetation and hydrologic improvements.

As the Design/Build contractor, SKS was first tasked with redrafting the project permits to more closely reflect actual site conditions, then to construct the project in close coordination with permitting agencies and park personnel. These tasks were accomplished while delivering to the client all anticipated mitigation credits, and staying within the original project time and budget.
