Amendment 0002 7297652 CP2006M Repairs to Central Heating Plant (CHP) Bldg 152

RFI Responses:

1. Can the existing As‐Built Drawings that reference the Design Loads for Central Heating Plant (CHP) Bldg 152 be provided by Amendment so that the temporary shoring for the required structural work can be designed by a Professional Engineer?

Submit proposals in accordance with RFP, Specifications, Drawings and all amendments. See attached amendment continuation sheet.

Note: The shoring design loads are shown on sheet S‐103.

2. Spec Section 01 45 35 indicates that Special Inspections are required for the Lateral Force

Resisting System (LFRS). The structural steel work required for the project is minimal in nature with the exception of the temporary shoring required as specified. Can Spec Section 01 45 35 be deleted by Amendment?

Note: Special Inspections are required for this project for all new steel and concrete construction so Section 01 45 35 cannot be deleted. The elements of the LFRS for the existing building are noted on the Statement of Special Inspections but are not being modified as part of this project so inspection of those elements is not required. Also see attached schedule of special inspections.

3. Spec Section 05 12 00 requires that the Structural Steel Fabricator and Erector are to be

ASIC Certified. There are very few ASIC Certified Fabricators and Erectors located within the US available that would meet these requirements that would be willing and able to work aboard MCAS Cherry Point. Can the requirement for the Structural Steel Fabricator and Erector to be ASIC Certified be removed by Amendment?

Note: The requirement for an AISC certified fabricator and erector has been removed. See revised specification section 05 12 00 – Structural Steel.

4. Spec Section 01 45 35, Paragraph 1.6.5 requires the Contractor to provide up to (5)

Professional Engineers in the Civil, Mechanical, Electrical, Structural and Architectural disciplines as part of the Contractors QC Staff to surveil and inspect these applicable definable features of work weekly during installation and including final inspection. The Plans and Specifications for the project have already been designed by several Professional Engineers. Also, Spec Section Spec Section 01 45 35 does not require the qualifications for these individuals to be submitted as part of the Contractors Quality Control Plan. In addition, having up to (5) PE’s on site on a weekly basis would substantially increase the cost of the project. Can the required QC Specialists for the project be removed by Amendment?

Amendment 0002 7297652 CP2006M Repairs to Central Heating Plant (CHP) Bldg 152

Note: The contractor is referring to specification section 01 45 00 – Quality Control. Stantec and the government agree to modify the requirements outlined in paragraph 1.6.5 – Quality Control (QC) specialists. See revised specification attached.

3.2.2.1 Installation of Direct Tension Indicator Washers (DTIW)

Where possible, install the DTIW under the bolt head and tighten the nut.

If the DTIW is installed adjacent to the turned element, provide a flat washer between the DTIW and nut when the nut is turned for tightening, and between the DTIW and bolt head when the bolt head is turned for tightening. In addition to the LIW, provide flat washers under both the bolt head and nut when ASTM F3125/F3125M , Grade A490 bolts are used.

3.2.3 Tension Control Bolts

Bolts must be installed in connection holes and initially brought to a snug tight fit. After the initial tightening procedure, fully tension bolts, progressing from the most rigid part of a connection to the free edges.

3.3 GAS CUTTING

The bolt tension must be developed by tightening the nut. A representative of the manufacturer or supplier must be present to ensure that the fasteners are properly used, and to demonstrate that the fastener assemblies supplied satisfy the specified requirements. Submit bolt testing reports.

3.7.3.2 Inspection

Inspection procedures must be in accordance with AISC 360 . Confirm and report to the Contracting Officer that the materials meet the project specification and that they are properly stored. Confirm that the faying surfaces have been properly prepared before the connections are assembled. Observe the specified job site testing and calibration, and confirm that the procedure to be used provides the required tension.

The nondestructive testing will be done in-place using an ultrasonic measuring device or any other device capable of determining in-place pre-load bolt tension. The test locations must be selected by the Contracting Officer. If more than 10 percent of the bolts tested contain defects identified by testing, then all bolts used from the batch from which the tested bolts were taken, must be tested at the Contractor's expense. Retest new bolts after installation at the Contractor's expense.

3.7.4 Testing for Embrittlement

ASTM A143/A143M for steel products hot-dip galvanized after fabrication.

Submit embrittlement test reports.

3.7.5 Inspection and Testing of Steel Stud Welding

Perform verification inspection and testing of steel stud welding conforming to the requirements of AWS D1.1/D1.1M , Stud Welding Clause.

1.4 GENERAL REQUIREMENTS

Establish and maintain an effective quality control (QC) system that complies with FAR 52.246-12 Inspection of Construction. QC is comprised of plans, procedures, and organization necessary to produce an end product that complies with the Contract requirements. The QC system covers all construction operations, both onsite and offsite, and must be keyed to the proposed construction sequence. The QC Manager, Superintendent, Site Safety and Health Officer (SSHO), and all on-site supervisors are responsible for the quality of work and are subject to removal by the Contracting Officer for non-compliance with the quality requirements specified in the Contract. The QC Manager must maintain a physical presence at the work site at all times and is the primary individual responsible for all QC.

1.5 QUALITY CONTROL (QC) PROGRAM REQUIREMENTS

Establish and maintain a QC program as described in this section. This QC program is a key element in meeting the objectives of the project. The QC program consists of a QC Organization, QC Plan, QC Plan Meeting(s), a Coordination and Mutual Understanding Meeting, QC meetings, three phases of control, submittal review and approval, testing, completion inspections, QC certifications, independent Special Inspections in accordance with Section 01 45 35 SPECIAL INSPECTIONS, and documentation necessary to provide materials, equipment, workmanship, fabrication, construction, and operations that comply with the requirements of this Contract. The QC program must cover on-site and off-site work and be keyed to the work sequence. No construction work or testing may be performed unless the QC Manager is on the work site. The QC Manager must report to an officer of the firm and not be subordinate to the Project Superintendent or the Project Manager.
