Follow routing shown for pipes, ducts, and conduit; place runs parallel with building lines. Use space efficiently to allow accessibility for maintenance and repair for each and every system. Conceal wiring behind finish surfaces and locate fixtures and outlets with finish elements. Coordinate pre-Substantial Completion clean-up in separate building areas.

4.2.6 Cutting and Patching: Only employ skilled and experienced workers to cut and patch. Report in writing to the CO wherever cutting and patching might degrade: safety; appearance, structure, weatherproofing, O&M, or separate Contractor or government construction. Prevent damage to existing and new construction and prepare surfaces to receive patching and finishing. Match new finishes to existing adjacent surfaces unless noted otherwise. Maintain integrity of existing walls, ceilings, or floors;

completely seal voids. Refinish entire assemblies and continuous surfaces to nearest intersection. Cut, fit, and patch where required e.g.: mechanical and electrical penetrations; integration of new components with one another or with existing construction; removal and replacement of defective and non-conforming elements; remove samples for testing.

4.2.7 Special Procedures: Employ skilled and experienced tradespersons. Remove debris from open work areas and concealed spaces. Remove, cut, and patch to minimize damage and provide means of restoring products and finishes to original or specified condition. If a change of plane of 1/4 inch or more is discovered, submit recommendation to the CO for providing a smooth transition. Patch or replace portions of existing surfaces damaged during construction.

4.2.8 Welding Permits: The Contractor must not cut or weld without first obtaining a welding permit from the Base Fire Department. All fire and safety regulations must be stringently followed.

Failure to obtain a welding permit will not be cause for extending the contract performance period.

Damages caused by welding work is the responsibility of Contractor.

4.3 SCHEDULING

4.3.1 CO and CEPM must approve Contractor work schedules before start of work. Work progress will be evaluated with the CO, BCE-CM, and Contractor in weekly meetings. The Government may require corporate management “in-person” (not telecom) representation at these meetings.

4.3.2 Contractor must schedule all work. Performance periods will not be established or extended to accommodate insufficient personnel resources. Contractor must not move crews on and off the project while making minimal progress as this shows the Contractor has an inadequate work force to fulfill the contract requirements. Contractor’s CPM and CSS must not change more than two (2) times during construction as this demonstrates an inadequate management force to fulfill contract requirements.

4.3.3 Before construction begins, Contractor must agree with CO regarding: access to premises and buildings; storage of materials and equipment; delivery of materials; use of delivery routes, approaches, corridors, and stairways. The Government may require the Contractor to revise work- schedules.

4.3.4 Interference and inconvenience to Government operations and personnel caused by project work including use and delivery of materials, tools and equipment must be minimum. Do not preclude the functioning of roof vents or exhaust fans for Subway and Ragin Cajun during normal business hours.

4.3.5 The Government may require that work, so far as practicable, be done in separate phases.

Phased work areas must be delineated and annotated in the Contractor’s drawings.

4.3.6 Hours of Work: Normal work hours are Monday through Friday from 7:30am to 4:15pm excepting the Federal Holidays listed below:

Work in CAFB occupied areas during extra-normal work hours require AF escorts in the occupied areas. Modification to contract sum or period of performance are not allowed.

3) The Government’s request for Contractor to work outside of the normal duty hours may justify revision of contract sum or performance period.

4) If CAFB observes an unscheduled holiday, participates in training exercises, etc., the CO may prohibit the Contractor from working for part or the whole of a day. 14CES does not know how many or when these activities might be scheduled, but anticipate not less than two per year.

BCE-CM will allow additional contract time for these disruptions. Zero-cost revision of performance period may be allowed.

4.3.7 Construction Schedule: Submit preliminary schedule to the CO at the Preconstruction Meeting, but not later than fourteen (14) days after issuance of Notice to Proceed. After CAFB review and comment, revise and resubmit schedule within seven (7) days. Upon approval by the CO, the schedule becomes the official Construction Progress Schedule. Keep a copy available at Contractor (field) Office.

Each and every schedule change must have prior CO approval via contract Modification.

4.3.8 Construction Progress Schedule: Submit and maintain an accurate and current Gantt chart to track construction progress with a separate horizontal line for each major work activity of subcontractors, manufacturers, and suppliers. Vertical lines must identify the first work day of each week. Show complete sequence of construction by activity, identifying separate stages of work and other logically grouped activities. Indicate early and late start, early and late finish, float dates, and duration of each activity. Revise chart weekly to accurately identify progress made, percentage completion, and projected completion date for each activity. Show activities modified and scope changes. Submit written report to identify problems, anticipated delays, corrective actions, and affected completion dates.

Provide additional progress schedule information as requested by the BCE- CM. Construction progress schedule update forms will be provided at the preconstruction conference.

4.5 MATERIAL SUBMITTALS AND SHOP DRAWINGS

4.5.1 Definitions: A submittal is a package of project information, samples, drawings, schedules, certifications, product data, etc., delivered to the Contracting Officer (CO) for Government review or review and approval. A deviation is a submittal with an item not requested in the project documents.

The Contractor may only submit a deviation if the item is in agreement with the intent of the project documents, but does not precisely conform to those documents and Contractor requests either substitution or change for the purpose of increasing the quality of the final product. A Submittal or Deviation of a system must be considered as an integrated collection of component parts.

4.5.2 Purpose: Submittals formalize Government review of Contractor choices in complying with the CDs and providing Minimum Installer Qualifications (Section 4.8.1). They also formalize Contractor’s proposed Deviations, color choices, shop drawings, etc. early enough in the contract time when changes have less impact on the ordering of materials and products.

4.5.3 Accountability: The Contractor is wholly responsible for the contents of a submittal. The Contractor by act of submittal certifies that each and every item listed or implied, meets the intent, materiality and requirements of the design, quality, and functionality of the CDs. Neither Contractor

01 SOW New BX Roof (r)C:\Users\1390999310C\Desktop\m7 CURRENT Projects\160 BX New Roof\Acta to CONS\01 SOW New BX furnishing nor Government approval of a submittal either suspends or waives Contractor responsibility for conformance to the CDs.

4.5.4 Basic Compliance: Conform to all “Material Submittals and Shop Drawings” requirements of the SOW. All submittals must be delivered to the Contracting Officer within twenty- one (21) days upon issuance of NTP-Construction. If submittals are not delivered within 21-days the CO may refuse Progress Payments until all submittals are delivered.

4.5.5 Submittals must be accurate, easily legible, with all detail necessary for a thorough review.

Every copy of Product data must clearly identify proposed models, options, and relevant design data including physical, functional, and utility connection requirements. Render manufacturer data specific to this Project.

4.5.6 The Contractor must review, approval stamp and sign every submittal before delivery to the CO. Each submittal package and shop drawing sheet must bear appropriate Design Professional (Designer of Record) license stamps and approval signatures before delivery to the CO. Each submittal must be attached to a Material Approval Submittal (MAS) Form (AF Form 3000). Upon Government review, one copy of each submittal will be returned with its MAS form marked to indicate approval or disapproval.

4.5.7 Government Review: Contractor must deliver four (4) copies of each submittal (if not submitting electronically) and must allow 14-days for review or review and approval excluding delivery time from and to Contractor.

4.5.8 Submittal Log: Contractor must during the design phase of the project log all construction submittals required by completing a “Schedule of Material Submittals” (AF Form 66). The form must include all submittals necessary to insure the project is built to the satisfaction of CAFB including shop drawings, manufacturer's literature, product data, certificates of compliance, material samples, finish samples, extensions to the design, guarantees, test results, etc. The CO will provide Contractor with an AF form 66 template. Contractor must complete and submit the AF Form 66 in MS-Excel electronic format and in hard-copy format to the CO for review and approval by the CEPM within fourteen (14) days upon issuance of the NTP. Form 66 will be the first submittal item and must be attached to its own (MAS) form. Place the entire Submittal Log in an appendix of the final specifications.

4.5.9 Proposed Products and Qualified Installers List: Within 28 days after Notice to Proceed is issued, submit list of major products proposed for use, with manufacturer name, trade name, model or catalog number designation, and reference standards of each product.

4.5.10 Material Approval Submittal (MAS): The CO will provide Contractor with a MAS form template. The MAS “Submission Number” must be the same as its corresponding “Item No.” in the Submittal Log. Each submittal must reference the specifications paragraph or the drawing sheet number where the submittal is required. Clearly mark an MAS form “DEVIATION” for any system or any part thereof to which the Deviation applies. Deviations must be reviewed by the CEPM.

4.5.11 Re-Submittals: Resubmitted MAS forms must bear the original “submission number” with an alphabetic suffix (sequenced for multiple re-submittals). Identify all changes made since the previous submission. Allow fourteen (14) days for government review excluding delivery time from and to Contractor.

4.5.12 Selection of Colors and Finishes: Submit samples of each and every exterior and interior finish (anything with a visible surface) including: surfaces, materials, textures, patterns, paint, fixtures, doors and frames, windows, glass and frames, and hardware before ordering or installation. The Contractor must submit to the CEPM samples of each and every available manufacturer color and finish to be used in the project. Submit EACH AND EVERY Color and Finish sample at the same time. Attach to each sample an AF Form 3000 with Project Number, Project Name and Submittal Number.
