ADDITIONAL INFORMATION: 1. RFI Question and Answer Log END OF ADDENDUM

Oxon Hill High School Replacement Question and Answer Log Issued via ADD#3

NOTE: For RFI Responses #1-6 & 7-44 Please see ADD#1 & ADD#2 45) RFI from Pleasants Construction Question: You indicate the 2Acontractor is responsible to patch and repair all roads, surfaces, and curb. Does this include streets that are off site as well? If so, do you have a condition survey of these streets Answer: The 02A Contractor is not required to patch, repair, and/or replace off-site conditions beyond what is indicated on the drawings. Answered by: Todd Ward, HESS 46) RFI from Pleasants Construction Question: We are to include 5% of the quantity for repair. Whose quantities is the 5% based on? Is the 5% the proposed paving or all of the proposed and temporary paving? Does the 5% include any off site repair Answer: The repair quantity is based on 5% of permanent work indicated on the drawings, and should not include temporary work. Answered by: Todd Ward, HESS 47) RFI from Pleasants Construction Question: The asphalt cement index references January 2011 which was $477.00, but the asphalt cement index is currently $630.00 for July 2011 and the asphalt producers on will price current index. Can this be revised to the month the project will be bid as you are already 32% increase from the Jan. 2011 index Answer: Bid should be based on current price index for the month that the project was bid. Answered by: Todd Ward, HESS 48) RFI from Pleasants Construction Question: If we are unclassified to subgrade, but may be required to grade as much as 4' higher that subgrade and indicated in the documents, what is the deciding factor? Will we be required to cut to subgrade, then replace this material to insure no unsuitable material? Answer: All excavation for this project is unclassified to lowest design sub-grade, which is defined by item #1 of the special considerations section of the 02A scope. If unsuitable soils are encountered at lowest sub-grade elevation, then any additional excavation required to

reach suitable conditions will be compensated through the unsuitable soils allowance, which is further defined by item #2 of the special conditions section of the 02A Scope. Answered by: Todd Ward, HESS 49) RFI from Pleasants Construction Question: Is the 40000 CY allowance paid by cross sectioning the area (in place)? Answer: Usage of the unsuitable soils allowance will be based on the quantity of CY of compacted replacement material. The manner in which the quantity is measured will be determined in the field by the CM and Geotechnical engineer, based on what is most practical for the specific condition. The 02A Contractor must receive written direction from the Construction Manager prior to proceeding with additional work. Answered by: Todd Ward, HESS 50) RFI from Pleasants Construction Question: Is there any contaminated dirt (from underground tanks or fuel spillage)? Answer: The conditions are unknown Answered by: Todd Ward, HESS 51) RFI from Pleasants Construction Question: If the earthwork does not balance between phases, will we be allow to stockpile excess as needed Answer: The 02A Contractor is responsible for surplus or shortage quantities of on-site materials in order to grade the site to designed grades per phase. On-site stockpiling is permissible, but the 02A Contractor must coordinate with the CM on the location and duration, as stockpiling may not impact the progression of new work, and/or impact areas of the site designated for school use. Answered by: Todd Ward, HESS 52) RFI from Pleasants Construction Question: Do to the limited space, will topsoil be allowed to be stockpiled and/or screened on site? Answer: Limitations described by Pre-Bid RFI #51 answer would apply for topsoil stockpiling and screening operation. Answered by: Todd Ward, HESS 53) RFI from Kinsley Manufacturing Question: Please clarify if our crane can get on the foot print of the building to set the steel Answer: It is not anticipated that crane staging would occur inside the building footprint for steel erection, as this would impact process of other trades’ work. However, in limited conditions and at the sole discretion of the CM, crane staging/crane paths within the building footprint may be permitted, if no other means/method of steel erection is feasible. Answered by: Todd Ward, HESS

54) RFI from Pleasants Construction Question: I was informed this morning that the Phasing plan and Sequence of Construction do not match with the grading requirements. Additionally, they do not address at any point when the Traps and Basins are converted to Bio-retention Areas. We are making assumptions but the work requires going beyond the Phases Limit of Disturbance. We will keep you up to date items as we encounter them Answer: Regarding grading requirements, the contract documents do not indicate every grading condition that may exist as the phasing/schedule progresses. There will be some flexibility allowed to determine the grading limits of new work (per phase) to accommodate existing conditions to remain (per phase), provided critical aspects of new work can be performed within its intended phase, and final grades at project completion are in accordance with the contract documents. Regarding trap/basin conversion, The SEC Phasing plans do address the sequence of work. In general, the conversation of basins/traps will occur after the drainage area associated for each device is developed to final condition. Answered by: Todd Ward, HESS 55) RFI from Kinsley Manufacturing Question: Please clarify the sprayed on fireproofing requirements. Package 05A Spec Section 05120 Structural Steel Section 2.6 – A – 4 states that surfaces that are to receive sprayed-on fireproofing do not get prime painted. Please clarify the steel that will require sprayed-on fireproofing. I have not seen anything on the structural drawings denoting that the steel is to be fireproofed. Answer: There is no sprayed on fireproofing requirements for this project. Answered by: Jim Gladhill, Hess 56) RFI from Karon Masonry Question: EGF – A (exterior ground face unit color A) is listed in the specification as a 16” high unit. The coursing references on the elevations, and wall cuts, are drawn for a unit that is 8” high. Wanted to double check that the height of EGF-A is 16” high. Answer: See Addendum #2 Answered by: Marty Lubin (WMCRP) 57) RFI from Kinsley Manufacturing Question: Please advise if there are site rails on this project. I find no site rails indicated or detailed on the contract drawings. Site rails are referenced in the following bid packages.Package 05A – Steel Specific Scope item 2 lists: Site railings, Site handrails, Site guard rails, Package 02A – Sitework under Site Amenities item 4 on page 14 of 18 lists: All exterior steel railings at exterior stairs, ramps, retaining, walls and all other areas throughout the site and building exterior.

58) RFI from R.D. Bean Question: Paragraph 2.5.8.2 has a list of approved manufacture's for the metal panels, but paragraph 2.5.B.3.b calls for the color to be "Tundra" by MBCI. MBCJ is not listed as an approved standing seam panel manufacture, but they do have a standing seam panel that is similar to the approved manufacture's standing seam panels. I would like to confirm that either the MBCI standing seam panel will be accepted, or that the color will be selected from any of the approved manufacture's standard colors. If the approved manufacture's are required to match the MBCI color then this would be considered a custom color and there is a significant up charge to match this color.

I would like to confirm that the listed manufacture's standard colors will be accepted. I the metal wall panels are to match the Architect's sample and the selected color is not a manufacture's standard color then this would be considered a custom color and there is a significant up charge to match this color. Also, if the color is to match the Architect's sample then we would need to know what the color will be prior to bid date so that we can have the manufacture's provide a price for the custom color.

Answered by: Bryan Jones (ESP) 178) RFI from Pleasants Construction Question: There is a sewer manhole referencing to be built over sewer existing line, commonly referred to has a "Doghouse Manhole". However WSSC do not allow these anymore. Answer: See WSSC standard detail S/2.0 for Precast Concrete Manhole Built over Existing Sewer. Answered by: Nicholas Barrick (KCI) 179) RFI from Pleasants Construction Question: In the Phase 2 sewer there is referenced a 8x10" reducer that is to be installed during Phase 1, however it is not listed on the Phase 1 plans. Answer: : Phase one water only calls for installation of a 4” water line and the 6” sewer connection for the field house. Refer to the plans. Answered by: Nicholas Barrick (KCI) 180) RFI from CT Electric Question: Could you clarify Detail 1 on sheet TE-4.1? Is item 933 supposed to be panel 1GP? Are these the same circuits shown on sheet E-123 (1GP-3,5,7 / 1GP-7,9,11 / 1GP-2,4,6 / 1GP-8,10,12)? The panel schedule calls for 1” conduit for these circuits but sheet TE-4.1 shows 1-1/4” conduits. Where is item 930, the Drive Enclosure, to be located? What size conduit is to be used between items 932, 931 and 930? What wiring if any is to be installed between these items? What wiring is needed between item 930 and the Low-Voltage Connector Strips? What changes need to be made if item 930 is not used? Answer: Yes, 933 is to be 1GP on sheet E123. This is to provide 4 ea 60 amp, 480VAC three phase power circuits, one to each strip. I sized the conduits at 1.25" to allow for #4 conductors in case the run distance is long. As long as the distance is short and you use #6, 1" conduit would appear to be the code size. The location of 930 is flexible, as not all winch manufacturers would use a control enclosure in their systems. Some build all the controls into the hoist itself and the operators station. Ideally it would be located at the catwalk level, down stage of the proscenium. If 930 is not used, control strip wiring goes directly to the operator’s station or to a junction box then to the station. Wiring between the control strips and the operator station is typically 10 to 12 conductors with maybe a network cable or Belden cable, this again depends on manufacturer. I am calling out 1.25" conduit, but smaller conduit may be acceptable once you have shop drawings from the manufacturer. Shop drawing requirements would over ride what is shown on TE-4.1 Answered by: Duane Wilson (Consulting For Theater Systems) 181) RFI from W.L. Gary Question: The lab sinks on plumbing schedule P-601 calls for either an acid neutralization tank or an acid trap. Riser diagram on P-703 show these completely piped out to an acid tank. Are

acid traps acceptable with only a small piece of corrosion resistant piping between sink/cup sink drain and trap? There is a substantial cost difference between the 2 options of either piping these our completely in corrosion resistant piping versus cast iron. Please clarify. Answer: It should be corrosive resistance piping and fittings all the way to an acid neutralization tank underneath of the sink groups. Answered by: Tom Green (ASE) 182) RFI from Steel Products Question: The specifications for the markerboards and tackboardss reference the snap on trim method of installation but mention factory built. If factory built is acceptable then the architect should reference claridge series 1 units as the basis of design or state only snap on trim on continuous grounds as the method of installation will be acceptable.

Also there are no other prefabricated display cases. Answer: See Addendum #3 Answered by: Marty Lubin (WMCRP) 185) RFI from TJ Distributors, Inc. Question: Section 12710, paragraph 2.1.F.5.b (page 9), states a power / data raceway is needed for the orchestra seating areas to extend the power from the opposite side of the seating section. Would it be possible for the seating contractor to locate the floor boxes required and have the electrical contractor install these in lieu of providing a raceway? Answer: : I have no objection to this approach as long as the seating contractor takes full responsibility for locating the boxes and any subsequent rework to get them in the correct place. Experience has shown that the coordination to locate the boxes in practice is iffy at best. This is the reason for specifying the seating raceway, as it would allow more flexibility in allowing the electrical contractor locate boxes in the knee wall and require less critical planning in pouring the seating slab.

26. Asphalt Binder Escalation: An adjustment will be made to the final Contract Sum if the price of

asphalt binder fluctuates from the prevailing price as quoted here to the actual price on the date of placement. The Contract Sum will be adjusted if asphalt binder fluctuation is above 10% or below negative 10%. Only the differential percent change beyond the above noted 10% will be used.

For the purpose of making these calculations, a monthly price index is maintained by the MD State Highway Administration. This index is the average FOB selling price of asphalt binder at the supplier’s terminal in the State of Maryland. Contract price adjustment will be computed monthly by using the following formula:

F= (PP-Pb)/Pb Where:

F = price increase/decrease of asphalt binder, expressed as a decimal PP = index price of asphalt binder per ton at placement date

Pb = the prevailing index price of asphalt binder per ton in January 2011, as specified by MDSHA.

Contract Price adjustment due to Contractor or Owner when price of asphalt binder does not increase or decrease significantly (i.e.: -0.10 >F>0.10) – Zero Dollars

Contract price adjustment is due to Contractor as a cost to Owner when price of asphalt binder increases significantly (i.e. F>0.10) – A= [(F-0.10) x T x Pb] x Tons Contract price adjustment is due to Owner as a credit to Contractor when price of asphalt binder decreases significantly (i.e. F< -0.10) – A= [(F-0.10) x T x Pb] x Tons Where:

A = Addition / Deduction to Contract Sum F = price increase/decrease of asphalt binder, expressed as a decimal T = design target asphalt content as stated in the asphalt manufacturer’s mix design

for base or surface course expressed as a decimal Pb = the prevailing index price of asphalt binder per ton in January 2011 as

specified by MDSHA Tons = ACTUAL Tonnage of Hot Mix Asphalt Base or Surface (Base & Surface Mix

cost increase/decrease will be calculated separately using the design target asphalt contents for each per “T” above), as documented by certified, dated, weighted tickets furnished by the asphalt manufacturer.

Please note that the Contract Price Adjustment does NOT include Overhead & Profit markup, which will not be allowed or required on adjustments due the Contractor or Owner. The Contract Price Adjustment also does not include a state sales tax or bond markup, but these markups/markdowns will be allowed/required on both adjustments due the Contractor and Owner.
