SECTION 01310
PROGRESS SCHEDULES
PART 1 - GENERAL

1.01   SUMMARY

       A.    Section Includes: Manually prepared construction schedule based on Gantt (bar)
             Charts. Prepare and maintain schedules and issue reports to assure adequate
             planning and execution of the Work. Complete Work within the number of calendar
             days allowed in the Contract. Schedule shall be in sufficient detail to assist the
             Architect in appraising the reasonableness of the proposed schedule and to evaluate
             progress of the Work.

1.02   DEFINITIONS

       A.    Day: As used throughout the Contract, the work "day" means "calendar day" unless
             otherwise indicated.

       B.    Adverse weather that is normal for the area and the season shall be taken into
             account in the Construction Schedule.

1.03   QUALITY ASSURANCE

       A.    Qualifications of Scheduling Personnel: Employ a project scheduler thoroughly
             trained and experienced in compiling construction schedule data and in preparation
             of periodic reports.

       B.    Reliance Upon Accepted Schedule:

             1.      The construction schedule, as accepted by the Architect, shall be an integral
                     part of the contract and will establish interim Contract completion dates for
                     various activities.

             2.      Should any activity fail to be completed within 15 days after the stipulated
                     schedule date, the Owner shall have the right to order the Contractor to
                     expedite completion of the activity by whatever means the Owner deems
                     appropriate and necessary, without additional compensation to the
                     Contractor, and as set forth in the General Conditions of the Contract.

             3.      Should any activity be 30 or more days behind schedule, the Owner shall
                     have the right to perform the activity or have the activity performed by
                     whatever method the Owner may deem appropriate, and as set forth in the
                     General Conditions of the Contract.

             4.      Costs incurred by the Owner in connection with expediting construction shall
                     be deducted from the Contract amount.

             5.      Failure by the Owner to exercise the option to either order the Contractor to
                     expedite an activity or to expedite the activity by other means, will not be
                     considered a precedent for any other activities nor a waiver of the Owner's
                     rights to exercise his rights on subsequent occasions.




                                                                        PROGRESS SCHEDULES

             SECTION 02080 - HAZARDOUS MATERIALS REMOVALS

PART 1 - GENERAL

       1.1    PROJECT SITE

       A.     The project site is identified as Magnolia Elementary School, located at 1905 Magnolia
              Avenue in Carlsbad, California. Buildings to be impacted include all five permanent
              buildings (A through E), two adjoining restroom portable buildings (collectively, Building F),
              and 16 portable classroom/office structures. Work areas shall include areas where
              hazardous materials are to be impacted by proposed modernization activities, as outlined in
              the Tables located in Article 1.2.G, below.

       1.2    SCOPE OF WORK

              A.      The main project goal for this project is the modernization of the subject buildings.
                      All hazardous materials identified within the subject buildings that will be impacted
                      by proposed construction activities are to be removed as part of the project.
                      Mitigation measures are also listed, where work items such as fastener installation
                      are to take place into or through materials known to contain detectable levels of
                      asbestos.

              B.      All removal and disturbance of asbestos-containing materials shall be performed by
                      an asbestos abatement contractor, using 32-hour asbestos certified workers
                      (Asbestos Worker trained as outlined in 40 CFR 763). Abatement contractor’s
                      workforce shall be supervised by experienced persons trained, knowledgeable and
                      qualified in the techniques of asbestos abatement, handling and disposal of
                      asbestos-containing and/or asbestos-contaminated materials, and the subsequent
                      cleaning of contaminated areas, including, at a minimum, Competent
                      Person/Contractor Supervisor training as outlined in 40 CFR 763.

              C.      All removal and disturbance of lead-based materials shall be performed by a state-
                      licensed contractor, using DPH-certified workers with at least one DPH-certified
                      Supervisor. All removal and disturbance of lead-containing materials (not meeting
                      the definition of “lead-based) as defined in 8 CCR 1532.1, shall be performed by a
                      state-licensed contractor, using lead-trained workers with certification of training
                      meeting the requirements of 8 CCR 1532.1. Abatement contractor’s workforce shall
                      be supervised by experienced persons trained, knowledgeable and qualified in the
                      techniques of lead abatement, handling and disposal of lead-containing and/or lead-
                      contaminated materials, and the subsequent cleaning of contaminated areas.

              D.      When exposure monitoring of a particular lead-related task indicates that the
                      permissible exposure limit is or will be exceeded, the contractor shall use DPH-
                      certified lead workers to complete the task. Contractors performing work that
                      disturbs any LCM must submit proof of negative exposure assessment (NEA) if
                      personal protective equipment is not to be used.

              E.      For Cal/OSHA compliance purposes, all other painted, varnished, and glazed
                      surfaces identified in the Hazardous Materials Survey Report (see Attachment A) as
                      containing lead require that contractors performing activities that will disturb these
                      surfaces/materials comply with the requirements of 8 CCR 1532.1. These surfaces
                      were identified in the above-referenced report to have detectable levels of lead, at
                      concentrations less than 1.0 mg/cm2 lead (the LBP standard) by X-Ray
                      fluorescence.

              F.      Contractor shall utilize employees with HAZWOPER training, as outlined in 29 CFR

       Notes to Tables 1 through 12:

       1. This material was found to contain less than 1% asbestos, and is an ACCM as per 8 CCR 1529.
       2. The exterior stucco was found to contain less than 1% asbestos, and is an ACCM as per 8 CCR
          1529, et al. Where stucco must be removed, such as where concrete sidewalk removal will
          necessitate the removal of small sections of adjoining stucco, stucco removal shall take place in
          accordance with Article 3.1 of this section (prior to concrete demolition). Where fastener
          installation is to take place through this material, such as when mounting signs with fasteners,
          work shall take place in accordance with Article 3.2 of this section.
       3. The scope of work calls for paint prep and painting of the doors and door assemblies and other
          painted/coated items associated with this building. The door assemblies (doors and/or frames)
          associated with these particular buildings are coated with lead-based paint. Any paint prep
          activities, including paint chip scraping back to a stabile substrate and sanding of the surface,
          shall be performed in accordance with Article 3.3 of this section.
       4. This material is listed for informational purposes, so that contractor is aware that the subject
          material contains asbestos, or that the subject paint/coating is lead-based. This item is not
          anticipated to be impacted by modernization activities.
       5. The vinyl floor tile and mastic throughout Building A are asbestos-containing. Only the floor tile
          and mastic within the Kitchen Area are to be removed.

          Survey Report, but appear to have either been removed or else were not identified within areas
          likely to be impacted by proposed modernization activities. In the event that they are
          encountered, they must be assumed to contain asbestos, or else additional testing should be
          performed to verify asbestos content:

           A. Roofing Materials on Buildings A, B and C were found to contain less than 1% asbestos.
           B. Transite (asbestos cement), found to contain up to 85% asbestos, was identified in the

                      2.     Project Environmental Consultant will then sample the air in the work area
                             for airborne fiber concentrations.



                      3.     Phase Contrast Microscopy (PCM): In each homogeneous work area after
                             completion of all cleaning work, a minimum number of samples will be
                             collected and analyzed in accordance with the NIOSH 7400 Methodology as
                             follows:

                             For work areas less than 160 square feet or 260 linear feet:

                             a.      5 interior aggressive air samples, 5 exterior air samples, 2 field blank
                                     samples and 1 lab blank sample for areas that had asbestos-
                                     containing materials removed.

                             b.      Release Criteria: Decontamination of the work site is complete when
                                     each sample analyzed reveals airborne asbestos fiber
                                     concentrations are at or below 0.010 f/cc, or established background
                                     concentrations.

                             c.      If these conditions are not met then the decontamination is
                                     incomplete and the cleaning procedures noted in Article 3.3 above
                                     shall be repeated. The area shall be re-tested at no additional cost
                                     to Owner until satisfactory levels are obtained.

                      4.     Transmission Electron Microscopy (TEM): In each homogeneous work area
                             after completion of all cleaning work, a minimum number of samples MAY be
                             collected and analyzed by TEM in accordance with the requirements of 40
                             CFR Part 763, Subpart E (AHERA) as follows:

                             For work areas equal to or greater than 160 square feet or 260 linear feet:

                             a.      5 interior aggressive air samples, 5 exterior air samples, 2 field blank
                                     samples and 1 lab blank sample for areas that had asbestos-
                                     containing materials removed.

                             b.      Release Criteria: Decontamination of the work site is complete when
                                     the average of the interior samples reveals that airborne asbestos
                                     fiber concentrations are at or below 70 structures/mm2, or
                                     established background concentrations.

                             c.      If these conditions are not met, decontamination shall be deemed
                                     incomplete, and the cleaning procedures noted in Article 3.3 above

1.8     PROJECT CONDITIONS

       A.    Weather Condition Limitations: Do not apply roofing membrane during inclement
             weather or when a 40% chance of precipitation is expected.

       B.    Do not apply roofing membrane to damp deck surface.

       C.    Do not expose materials vulnerable to water or sun damage in quantities greater than
             can be weatherproofed during same day.

       D.    Proceed with roofing work only when existing and forecasted weather conditions will
             permit unit of work to be installed in accordance with manufacturer's recommendations
             and warranty requirements.

       E.   (If Applicable) all slopes of greater than 1-1/2:12 require back-nailing to prevent slippage
              of the ply sheets. Use ring or spiral shank one (1) inch cap nails, or screws and plates
              at a rate of one (1) fastener per ply (including the modified membrane), at each insula-
              tion stop. Place insulation stops at 16 ft o.c. for slopes less than 3:12 and (4) ft o.c. for
              slopes greater than 3:12. On non-insulated systems, nail each ply directly into the deck
              at the rate specified above. When slope exceeds 1:12, strapping plies is recommended
              to help prevent slippage. Install for (4) additional fasteners at the upper edge of the
              modified bitumen sheet when strapping the plies.


1.9    SEQUENCING AND SCHEDULING

       A.    Sequence installation of modified bituminous sheet roofing with related units of work
             specified in other sections to ensure that roof assemblies, including roof accessories,
             flashing, trim, and joint sealers, are protected against damage from effects of weather,
             corrosion, and adjacent construction activity.

       B.    All work must be fully completed on each day. Phased construction will not be ac-
             cepted. Contractor must glaze any exposed felts, before next day’s work.

             system to comply with governing regulations and specified insurance requirements.

      C.     Protect other work from spillage of modified bitumen roofing materials, and prevent liquid
             materials from entering or clogging drains and conductors. Replace or restore other work
             damaged by installations of modified bituminous roofing system work. Note: Where
             there are existing roof curbs that have been roofed, they are to be demolished, new deck-
             ing installed, and to be re-roofed per specifications.

      D.     Coordinate installing roofing system components so that insulation and roofing plies are
             not exposed to precipitation or left exposed overnight. Provide cut offs at end of each
             day's work to cover exposed ply sheets and insulation with two (2) plies of #15 organic
             felt set in full moppings of bitumen and with joints and edges sealed with roofing cement.
             Remove cut offs immediately before resuming work. Install new counter-flashing, fur-
             nished, and warranted by membrane manufacturer.

             mended by NRCA. Do not raise temperature above minimum normal fluid-holding tem-
             perature necessary to attain EVT (plus 5 ºF at point of application) more than 1 hour prior
             to time of application. Determine flash point, finished blowing temperature, EVT, and fire-
             safe handling temperature of bitumen either by information from manufacturer or by suit-
             able test. Do not exceed recommended temperature limits during bitumen heating. Do
             not heat to a temperature higher than 25º below flash point. Discard bitumen that has
             been held at temperature exceeding finishing blowing temperature (FBT) for more than 3
             hours. Keep kettle lid closed except when adding bitumen.

      F.     Bitumen; Mopping Weights: For interply mopping, apply bitumen at the rate of approxi-
             mately 25 lb of asphalt per roof square (plus or minus 25 percent on a total job average

      G.     Substrate joint penetrations: Prevent bitumen from penetrating substrate joints, entering
             building, or damaging roofing system components or adjacent building construction.
