PARAGRAPH / SECTION NO:3.1, 3.2, 7.2.1.1

TITLE: 127,128,139,140 - Underdeck Stiffeners

QUESTION: Contractor finds a common misunderstanding within these 4 WIs.

Specification states there are underdeck stiffeners to be renewed but then goes on to identify the quantities as Linear Feet of steel plate.

Question was asked on items 0127 & 0128 regarding this and the Answer was “Linear Feet of steel plate.”

Same questions were asked on items 0139 & 0140 regarding this and the Answer was “Paragraphs 3.2 and 7.2.1.1 are Linear Feet. These are horizontal and vertical stiffeners.”

Is the intent of these items to replace the underdeck Transverse Stiffeners & Longs in these WIs?

The vertical stiffeners mentioned are confusing as well as the Linear Feet of Steel Plate.

Is the contractor to assume there is no deck plate to be replaced in these WIs? If there is could the specifications be modified to reflect how many Sq feet of Deck Plate should be included along with the Underdeck Transverse Stiffeners & Longs?

ANSWER: No deck plate renewal on this WI. WI’s revised.
