Project North Terminal Project - NOLA (MSY) Construction Subject Volume 3.1/NT SC 1221A/Concourse B & C /Lower Roof - Special Joist to Beam Connection Required

Subject: Volume 3.1/NT SC 1221A/Concourse B & C /Lower Roof - Special Joist to Beam Connection Required Date Required: 2016-07-25 Cost Impact: Potentially Cost Amount: Question: At the concourse low roof the 'kinked' W30x90 beams and the 'skew' W24x55 beams highlighted on the attached plan are set at

underside of roof deck level. Note that the W30x90 beam has moment connection at each end so needs to be set at this underside of roof deck level. MBJ connection details are also based on these beam elevations. The incoming joists will need a special seating bracket added to the support beams to allow for the joist to bear on the seat and field weld. Please provide suitable details. Note that revising any beam levels in this roof area will create additional detailing rework hence it is preferred that a special detail is developed for the connection of the roof joists.

Suggestion: Answer: NOTE: An RFI response cannot change the requirements of the Contract Documents. Response By: Kiran Tamvada Date: 07/25/2016 CCAT Response: See attached WPM-DSI-0031 for the special detail requested at these joist locations.

Cost Impact: None Pursuant to paragraph 4.2.14 of the General Conditions of the Contract, the Engineer of Record provides the following response to the referenced RFI. This RFI response does not constitute a Construction Change Directive, and does not authorize changes in project scope, contract price or time. Refer also to Article 7 of the General Conditions and for AIP work to Article 50-16 of the FAA General Provisions. RFI’s are to be returned for reconsideration if there is a cost or schedule impact.
