Part 4: Meetings, Submittals, and Deliverables:

1. Kick-Off Meeting and Documentation

A. The contractor’s Project Manager and Field Supervisor shall attend a Preconstruction Safety and Coordination Meeting to discuss project details.

B. Kick-Off Meeting Documentation:

1) Prepare and submit for review and acceptance a proposed baseline schedule reflecting each phase of the work beginning with Mobilization, including each critical activity, and each essential task required to optimally meet the objectives of the project. It is expected that this timeline will be shorter than that presented in the Period of Performance from Mobilization to Closeout. Upon acceptance, this will become the Baseline Schedule from which subsequent progress updates are developed and reported, and how progress payment applications are objectively reviewed.

2) To enable objective assessment of costs and progress, submit a fully-loaded time and cost schedule using Critical Path Method (versus Network Analysis) and accompanying Schedule of Values with harmonized category values – each totaling the contract value.

a. Develop the CPM schedule in sufficient detail to enable readers to understand all planned activities, their predecessors and successors, who is performing the work, durations, and costs. Activity durations shall not exceed two calendar weeks.

b. Use the Project Manual index of specifications is a useful guide for starting the CPM schedule and Schedule of Values in sufficient detail. For example: Simply listing “HVAC” is unacceptable for projects including more than basic work in this category. The inclusion of specifications for an AHU, controls, ductwork, demolition of each, testing and balancing, etc. also prompt their inclusion as categories of activities and tasks in the schedule. In fact, for larger work categories, breaking down the cost by system/material and installation and testing enables partial payment for higher cost items upon delivery into the facility work area.

c. Preparation and processing of submittals are not work activities contributing to the compensable work in the field. Should the contractor elect to include submittal planning in the schedule for their own purposes, do not show those line items in the schedule submitted to VA for consideration in the Baseline Schedule.

d. Not less than one item per subcontractor at any tier. Subcontractors, by definition, are contributing work in the field to the project.

e. Include all expected utility system shutdowns, crane lifts, and off-hours work.

f. Do not list dollar values for administrative, planning, submittals, mobilization, or demobilization, closeouts, or other non-work activities (work to be completed in the field which adds value to the final product). Distribute (prorate) the administrative, overhead, and profit values evenly through the work activities to determine their value. Do not front-load the values of the schedule of values.

The costs shown must be the actual value of the work put in place.

3) The contractor shall prepare and submit SF-1413 for each subcontractor to the CO, copying the COR. List of all subcontractors and suppliers, including:

Company names, office address, and main point of contact name with telephone number.

4) As required at 01 35 26 Safety Requirements: Develop and submit a Project-

Specific Construction Safety and Accident Prevention Plan with project-specific procedures, processes, analysis, and details, including but not limited to:

a. Access and use the U.S. Army Corps of Engineers EM 385-1-1 Safety and Health Requirements and its Appendix A – Minimum Basic Outline for Accident Prevention Plans for development of meaningful, effective, and compliant project safety plans.

b. Submission of generic, non-project specific plans will be rejected, resulting in a contractor-caused delay in commencement of the work.

c. Project-specific Activity Hazard Analysis, which forms the basis of the Construction Safety and Accident Prevention Plan highlighting identified risks such as isolation of stored energy (Lock-Out*), fall protection, or confined space access.

d. (*) Note that tag-out is not an acceptable form of isolation, therefore it was intentional not to use the term LOTO.

e. Submit an electronic copy of all workers OSHA 30-hour Construction Safety Training certificates or cards prior to allowing entry to the site.

f. Assist the COR in completing project-specific VA Infection Control Risk Assessment (ICRA) documentation.

C. Quality Control Plan and Quality Assurance Plan:

1) 01 40 00 Quality Requirements is included in its entirety in this contract. This specification is brief but very informative and enabling to those who approach it as an opportunity.

2) Submittal Tracker Log is described in Quality Assurance of the above specification.

3) (Dis)Approval of a submittal never constitutes a change to the quantity, quality, cost, or duration of a contract. The General Contractor is solely responsible for submitting and delivering complete and compliant work. Defective work shall be removed and replaced at the contractor’s expense. The Government has the right and responsibility to withhold funds equivalent to the cost for the Government to complete the work should the contractor fail to promptly act in executing the work or remedying defective work.

2. Construction Progress Meetings:

A. The Contractor’s Project Manager and Field Supervisor shall provide on-site weekly construction progress meetings with the COR for the entire period of performance.

B. Include preparation of meeting agendas, and subsequent minutes of the meeting for each event not later than 1 day (next business day) after each meeting.

C. Construction Progress Meeting Agenda’s and Minutes shall include: List of invitees/attendees, list of past/ongoing and new issues or concerns, indicate days remaining per the contract, detail any safety incidents, and include current updated copies of the RFI Log, the Shop Drawing Log, and a detailed 2-week look-ahead and utility shutdown schedule.

3. Daily Reports:

A. The Contractor shall provide a Daily Report each day, along with accompanying digital photos and other supporting documents. The Daily Report shall include: List of issues or concerns, days remaining per the contract, detail regarding any safety incidents, detail of daily safety inspections (including items checked and corrective actions taken), notations regarding any visitors to the work area.

B. Use of VA Form 10-6131 Daily Log (fillable PDF) and VA Form 10101 Contractor Production Report (fillable PDF) are required each day – even on days with no contractor activity, which is what to report on such days.

C. The report must be accompanied by relevant time and date-stamped photos of construction progress of sufficient quantity and detail to enable viewers to clearly see the progress of all work to-date, all issues discovered (including those which become the subject of RFI’s).

A. Locks and Keys: Temporary and permanent door hardware shall be compatible with Best® 7-pin, G-keyway, interchangeable core. Prior to commencement of work, the contractor shall provide VA with blank cores; quantity matching the number of openings planned. VA shall then provide construction coring, and a key for same to the General Contractor, who will sign acknowledgement and receipt and responsibility for the key until returned to the VA COR. Final pinout and keying are provided by VA.

B. Exit Signs: All exit signs shall be City of Chicago approved specification red letters on white edge-lit LED fixtures continuously illuminated 90 mins after loss of power, push-to-test switch and LED pilot light on the housing, available as single or double-sided models, and meeting UL924.

C. Building Automation: Components, programming and start up: Native BACnet communications protocol for Building Automation and Control (BAC) connected to the existing Johnson Controls head end equipment

D. 27 15 00 Communications Cabling (and other specifications which include telecom cabling): All new telecom cabling shall be Cat 6a vs. 5e. Cat 6a telecom cable, termination punch-down T-568-(B.1, B.2, C.2, etc.), tested and certified (submit result to COR), 6-port modular wall jacks with two RJ45 on top and bottom and two blanks in middle. While VA facilities generally do not include plenum return spaces above ceilings, it nonetheless requires plenum-rated teledata cabling complying with codes pertaining to plenum environments.

E. 22 05 23 General Duty Valves for Plumbing Piping (multiple occurrences), and all other occurrences of specification for similar valves:

a. Bronze (brass) valves and fittings of any type shall be incapable of dezincification, not dezincification resistant materials. Alternatively, (simply) provide valves meeting the following minimum requirements: Domestically-manufactured premium brand products made of 316 stainless steel housing, ball, stem, lever nut, and handles, as well as (reinforced; modified) PTFE seats, packing, and seals, and 250 lb. steam trim

– regardless of service less than this rating. Selected valves shall also include 2.25” extended stems to enable insulating the entire valve with 2” preformed insulation and all-weather jacketing, while leaving the handle lever exposed and operational, with no potential for rough edges which could harm maintenance staff (fold metal jacketing in, typ. Of these locations). Lever handles shall include spring-loaded latch lock handles which enable lock-out and prevent inadvertent handle movement.

Exceptions to the content regarding levers or ball-type operation include locations where other types of valves are indicated (ex. gate, butterfly, actuated, etc.). These exceptions do not relieve the requirement for dezincification-proof metallurgy.

b. Valves shall be installed within “strike-zone” reach of maintenance workers, standing on the floor, without being caused to reach around obstructions – especially hot surfaces, and secured to prevent torque-fatigue damage to connected piping and fittings. Where valves must be installed above the specified range, configure for chain operation, and provide valve operation chain within strike-zone reach of maintenance workers. Do not configure with site or shop-fabricated levers which can become a head-injury hazard.

c. Ensure lever handles point in the direction of flow when open.

d. Drain-down valves shall be fitted with a pipe nipple (after/below the valve) of sufficient length to prevent scalding operator’s hand when opening the valve handle and equipped with a tethered threaded cap for use in prevention of inadvertent discharge or especially scalding during periodic maintenance.

e. Alternatively, depending on configuration, provide a threaded brass hose thread connection after the valve, and install a hose rated for steam use which runs to a nearby floor drain without crossing walking paths or otherwise creating a trip hazard.

F. 22 07 11 Plumbing Insulation:

a. All hot or cold content piping shall be completely insulated, except for flanges (distance equal to bolt or stud plus one inch), unions (allowing removal of nut without removal of insulation system), valve and gauge stems, and similar locations requiring inspection or periodic maintenance.

b. The all-service jacketing (ASJ) described as white finish with kraft paper bonded to aluminum foil and fiberglass reinforced with pressure-sensitive adhesive closure is important to the performance of a pipe insulation system, but not complete. In fact, the text appears to describe a proper vapor retarder-enhanced, pre-formed fiberglass insulation product. The system must be completely sealed and protected, yet serviceable. All piping insulation shall be pre-formed type, including longitudinal and circumferential fittings and completely sealed from outside air and moisture. Where proper fitting of preformed insulation is impractical or impossible, ceramic wool offers an effective solution. Use of aerosol expanding foam products is not allowed on mechanical components.

c. Use of glass fiber or metal fabric or netting with or without asphalt or epoxy resin, mastics, or cements, is outmoded for this application as well as costly, and unreliable, as is the use of pins, nails, staples, and or tacks. Experienced insulation mechanics know how to cut and place materials properly, ensuring tight joints and even surfaces ready for installation of vapor retarder system, and then PVC or metal jacketing – including exposed ends at unions and flanges.

d. For indoor locations at low operating temperatures provide PVC jacketing, including pre-formed elbow, tee, and end covers, completely sealing all insulation. Do not use fasteners, adhesives, or assembly methods not expressly approved by, or provided by the PVC jacketing manufacturer. Outdoor locations, and indoor systems with operating temperatures PVC jacketing is not indicated for, provide corrugated aluminum or stainless sheet metal jacketing, including pre-formed elbow, tee, and end covers trimmed tightly to prevent air gaps - completely sealing all insulation.

Where air gaps occur, careful use of silver color GE or another premium brand silicone caulk is acceptable. Use ½” (nom.) aluminum or stainless-steel bands over metal jacketing. Use of 18 gage soft annealed aluminum wire during assembly is acceptable provided it does not affect the jacketing.

e. Where painting pipe is specified, allow to fully cure before applying insulation.

Always label new work ASBESTOS FREE over jacketing. No part of the piping insulation system shall obstruct access and reading specified brass valve and device tags. Apply ANSI/ASME A13.1 standard pipe labels over installed jacketing.

f. Provide a laminated P&ID drawing labeled with tag numbers along with a laminated Isolation Device Listing for compliant lock-out planning and execution.

16. Sole Source Procurement, the contractor shall provide fully functional complete systems, including the following sole source procurements for the following special systems:

A. Fire Alarm: Components, programming and start up within the West Campus is by Johnson Controls/Simplex.

B. Building Automation: Components, programming and start up: Automated Logic Company of Chicago.

C. Proximity card reader and door lock release entry system: Components, programming and start up: eNorman
