About this file

Written by GovTribe AI · Dec 28, 2023

This document provides details for a federal contract solicitation for maintenance dredging of the Alafia River Channel and Turning Basin in Hillsborough County, Florida. The U.S. Army Corps of Engineers seeks bids for dredging shoal material from the channel and basin to required project depths of 33 to 34 feet with one foot of allowable overdepth. Material will be disposed at the DMPF-3D disposal site located south of the channel. In addition to dredging and disposal operations, work includes repairing a north weir outfall pipe, conducting environmental and turbidity monitoring, bird monitoring, and managing disposal operations. Bids are due by July 2, 2021. This is a total small business set-aside for a contract valued between $1,000,000 to $5,000,000 with an estimated performance period of 260 calendar days after notice to proceed.

DIFFERING FROM THE VDATUM MODEL IF IT WERE to be USED AS A STAND ALONE PRODUCT

REFINEMENTS IN THE VDATUM MODEL, THE KTD FILE MAY CONTAIN EDITS OR ADDITIONS

(KTD) ALLOWING FOR REAL TIME VERTICAL DATUM CORRECTIONS. DUE TO ONGOING

MARCH 2018. THIS MODEL WAS USED TO CONSTRUCT A KINEMATIC TIDAL DATUM GRID FILE

THE NOAA VDATUM HYDRODYNAMIC TIDAL MODEL VERSION 3.8, RELEASE DATE OF 06

THE NAVD88-MLLW RELATIONSHIP FOR THE EXTENTS OF THE PROJECT IS DERIVED FROM

TIDAL MODEL:

(NOAA). ORTHOMETRIC HEIGHTS ARE REFERENCED TO THE NORTH AMERICAN VERTICAL DATUM OF 1988 (NAVD88).

NATIONAL TIDAL DATUM EPOCH, AS PUBLISHED BY THE NATIONAL OCEANIC AND ATMOSPHERIC ADMINISTRATION

THE TIDAL REFERENCE GRADE FOR THIS PROJECT IS MEAN LOWER LOW WATER (MLLW), OF THE 1983-2001

:VERTICAL REFERENCE SYSTEM

CHANNEL FRAMEWORK DESIGN FILE FOR THIS PROJECT.

CHANNEL WIDTHS AND LIMITS CONFORM TO THE AUTHORIZED PROJECT DIMENSIONS, AS SHOWN IN THE MASTER

RELATIVE TO THE INDICATED CHANNEL BASELINE FOR EACH CHANNEL REACH. UNLESS OTHERWISE INDICATED, MEASUREMENT UNITS ARE THE U.S. SURVEY FOOT. CHANNEL STATIONING AND OFFSET COORDINATES ARE

COORDINATES ARE SHOWN IN THE FLORIDA STATE PLANE COORDINATE SYSTEM (SPCS)WEST ZONE (0902).

BASED ON THE CURRENT VERSION OF THE NOAA NATIONAL SPATIAL REFERENCE SYSTEM (NSRS). GRID
