APPENDIX 1: Purpose and Objectives

DEMOLITION/DECONSTRUCTION:

Replacement of the existing 100-year old miter gate leaves will require removal and disposal of the old gates and fabrication/delivery of two (2) new gate leaves. Each new gate leaf is estimated to weigh approximately 375,000 lbs. Horizontal and vertical concrete removal will be required to remove the existing gate quoin blocks, pintles, and gate anchorage embedded metals.

Heavy-lift crane operations for removal and installation of the new miter gates will be required, with limited land based access to the gate location for equipment. Any use of floating-plant heavy-lift cranes will need to operate within the constraints of the lock dimensions and existing structures for adequate boom clearance and swing radius. The main lock chamber is 80 feet wide, with an overall chamber length of 825 feet, and an upstream pool draft of 33.5 feet when the saltwater barrier is down, and an upstream draft of 16.0 feet with the saltwater barrier raised. Downstream pool elevation varies with two (2) high tides, and two (2) low tides each day. Average water surface elevation for lower pool is 29.0 feet but can vary down to 15.0 feet of draft during extreme low tide (See Figure 3).

The sequencing of concrete modifications, in conjunction with allowing navigation traffic thru the lock chamber, will require the design/fabrication/installation/dewatering of localized steel cofferdams to isolate work areas “in the dry” to perform the work.

One lock chamber dewatering is anticipated to adjust and commission the miter gate after installation.

The duration of the dewatering is expected to be 45 days. The dewatering will be scheduled in advance and shall not be executed consecutive to another dewatering. The Government will perform the initial dewatering of the lock chamber for each closure period and the Contractor will be responsible for all maintenance pumping to keep the lock in a dewatered condition during the construction periods.

NEW GATE INSTALLATION:

The new contractor-fabricated miter gate leaves will be installed in the existing gate recesses with new gate anchorages placed into the concrete. New intermittent contact quoin blocks and sealing surfaces will be retrofitted vertically in the concrete gate monoliths. The new gate pintles will incorporate self-lubricating pintle balls as part of a fixed-pintle design into new embedded metals at the bottom of the lock chamber. The existing gate operating machinery will be reused and connected to the new gates. Existing electrical equipment on the gates will be removed and reinstalled on the new gates.

PROJECT BACKGROUND

INTRODUCTION TO BALLARD LOCKS

The Lake Washington Ship Canal (LWSC), known to Seattle residents as the Ballard Locks or Hiram M. Chittenden Locks, were built by the U.S. Army Corps of Engineers and dedicated in 1917.

LWSC is a man-made waterway that allows recreational and commercial navigation between the Puget Sound and Lakes Union and Washington.

The pool in the lakes is maintained by the Locks which separates the saltwater of Puget Sound from the fresh water in the remainder of Lake Washington Ship Canal, Lake Union, and Lake Washington.

The project consists of the Hiram M. Chittenden Locks and Dam with associated facilities in Salmon Bay; the 5,800 foot Fremont Cut between Salmon Bay and Lake Union; and the 2,500 foot Montlake Cut between Lake Union and Lake Washington.

INTRODUCTION TO BALLARD LOCKS

The project is categorized as a Dam Safety Action Classification 2 or high hazard potential classification in the National Inventory of Dams.

The LWSC is currently authorized for navigation, fish passage, and recreation.

The project was originally authorized for two purposes: navigation and fish passage, by Public Law 61-264, River and Harbor Act of 25 June 1910, 60th Congress, First Session, in accordance with a plan set forth in House Document 953, 60th Congress, First Session. Recreation was added as an authorized purpose in the 1940s for all Corps projects in Public Law 534, Section 4 of the Flood Control Act of 1944.

Water surface elevation control (pool regulation) is related to the need for water for navigation and fish passage.

CONSTRUCTION CONSIDERATIONS

CONSTRUCTION OVERVIEW

Design Bid Build

Significant Constraints:

• Physical limitations of work area footprint – No large cranes on land adjacent to the Administration Building

• Weight of gates is significant – Heavy lift crane to lift into place

• Environmental and Cultural Resources consultations in progress – Mobilization to the site can’t occur before these are complete

• Dissimilar metals and corrosion submittal must be approved by Government

Requirements covered under Specification 01 56 00

Government Phasing Concept Provided

– Phase 1: Fabrication of long lead items

– Phase 2: Physical construction onsite

CONTRACT REQUIREMENT

• Performance Specification and Drawings to support.

• Contractor to develop Construction Schedule that incorporates fabrication separate from mobilization and construction, plus minimizes lock outages (either length of each outage or the total number of outages).

• Submittals requiring Government approval include:

Dissimilar metals and corrosion In-depth QC plan

• Water Diversion during Construction:

Lock outages and dewatering schedule Cofferdams to reduce outages and allow navigation traffic to pass

– Maximum Flow Capacity of no less than 6,500 CFS

– Forebay Elevation not to exceed 674’ within design flow

– Allow vessels 75’ wide or smaller to pass

• Two approaches:

Option #1: Separate Supply Contract and Construction Contract Option #2: Single Construction Contract with partial NTPs issued - #1 for fabrication and #2 for construction

WORK WINDOWS

In Water Work Window: Typically, October 15th through February 15th but minor changes could occur following Endangered Species Act consultation and/or Tribal coordination.
