Sea Wall Update

Sea Wall Update: Cameron Duncan- TranSystems

Investigation & Capital Improvement Program Overview

seawall update

  • Assess present conditions (both above and below water)
  • Calculate the wall static and seismic stability to evaluate the risk
  • Develop repair alternatives and costs
  • Prioritize repairs
  • We have collected the data in Phases A & B and assigned a relative condition ranking to each city block. When Part C is complete the community will have a 25 year Capital Improvement
  • Program report which details the timing and cost of repairs recommended to mitigate the risk of wall failures and maximize their remaining life of the seawalls.
Phase A Investigation

Phase A Investigation

  • Rapid Reconnaissance of approx 25 properties both above and under water.
  • Excavation to confirm the landside wall conditions and (10) Tie-back conditions
  • Concrete Cores with petrographic examination to determine the type of chemical attack occurring.
  • Evaluate which Testing Methods are yielding the most valuable data.
  • The results were used to develop the best value strategy of Phase B testing for the entire community.
Phase B Investigation

Phase B Investigation

  • Strategic Sampling at a minimum of 3 locations along all 3 sides of every city block (each side of a block is an exposure segment). (304) total inspection locations on (140) seawall exposure segments.
  • Testing included: Visual descriptions, photos, measurements and relative rating by two separate engineering teams; non-subjective materials testing and non-subjective Non Destructive Testing.
  • Each exposure segment was then ranked by weighted calibration of the data.
  • Rankings are adjusted to connect trends between data points and isolate out “high risk” anomalies which may require individual attention vs. the repair of an otherwise good condition segment.
Above Water Findings

Above Water Findings

  • Seawall Scaling/Erosion is due to an expansive reaction called alkali-silica reactivity.
  • Silica in the concrete aggregate reacts with the salt (alkalis) in the seawater. The loss or depth of weak concrete ranges from 0-4” of depth and varies dramatically by seawall exposure/environmental orientation. In general this damage is worse on Zurn walls but structurally significant on both wall types.
  • The back face of the wall is in significantly better condition than the front face.
  • The tie-back rods are in generally in good condition.
  • The Boise Wall Pilasters repairs are performing well but there are additional properties in timely need of this repair.

Below Water Findings 1

Below Water Findings

Below Water Findings Slide 1

Below Water Findings Slide 1: Slope repairs are working well, where performed, but a dozen areas of undermining concern were identified by the engineering crew which swam all 7 miles of the seawall in Phase B.

Below Water Findings 2

Below Water Findings 2

Below Water Findings - Slide 2

Below Water Findings – Slide 2: Continuous 1″ wide Separations occur on many Zurn wall foundations between cutoff wall and footing. It is a concern since marine bores may be able to access to timber piling. It is a very inexpensive fix to fill with sand.

Landscape Update

Landscape Update

New Contractor (Kaneko Landscaping) started in July 2012

They have begun program to re-plant along Harbor Blvd. Start with thinning out existing landscape. Plan to start replanting this Spring.

Water Quality Update

Water Quality Update

  • DR Horton completed their 5-year commitment to testing the water within Seabridge
  • Working with City to continue testing
  • Working with Seabridge and Westport to create a organization to advocate for better water quality
  • Working to expand the area of testing to the entire harbor
  • Last testing showed a rise in DDT and decreased oxygen levels

The Board’s role on behalf of the owners
and residents of Mandalay Bay is to:

Monitor Maintenance and Advocate for the Timely Repair and Maintenance of the Mandalay Bay Seawalls and Channels.
