When the plan says all demolition, can we take that to mean all electrical, mechanical / HVAC, and plumbing will be done by the City? For instance, will the plumbing demolition include removing sinks, water cooler, toilets, and performing any new floor trenching required for the new plumbing work? Will the electric work include removing all the designated lighting fixtures as well as any wiring as required? Response COM DPW: It is the intent of the City to have the Contractor do all the demolition. Contractor shall follow the pricing schedule as shown on page 21 and bid demolition as a separate cost. Should the total base bid construction cost which will include the demolition be higher that the budgeted amount will allow the cost to be deducted and the city to perform the demolition. All furniture, office equipment, shop equipment and stored items will be relocated prior to any work being started.

4 23) If it is determined the contractor is to do the demolition work is it necessary for the contractor to hire a demolition firm per note E on page A0.6? Response JFHAIA: It is the choice of the contractor to perform demolition on their own or hire demolition specialty sub-contractor, the requirement remains to provide documentation of minimum 5 years experience demonstrating prior projects demolition work. 24) Is the parking garage concrete floor supposed to get a new coat of sealer? If so how many coats? Response JFHAIA: Yes, provide coats per product manufacturer requirements to maintain the warranty of the product. 25) Ceiling insulation: Partition plan details on a1.3 call for insulation 2 on either side of the office walls. A note on detail 2 on a2.1 indicates insulation over the entire acoustic ceiling. The difference is about $1,000. Which detail is correct? Response JFHAIA: partition type detail on A1.3 applies for partitions between offices and training room only. Follow detail #2 on A2.1 to provide and install continuous insulation on entire area above Open Office # ) Are the new steel stairs to be painted? 27) Plan page A0.2 Division 02 Existing Conditions note 1.2 F- Cover and protect furniture, furnishings, and equipment that have not been removed- We would like some written scope commitment as to the expected condition of owner s occupancy/stuff at the start of our work so that we can include an appropriate effort for this action in our bid. Response JFHAIA: See response to question #1 28) Plan page A Metals note 1.5 B&C reference inch-thick metal. Likely typo and maybe.0538 or 17 gauge was intended however this will still leave conflicts with many other notes that reference 20 GA steel ie: Plan page A2.2 detail 6. Response JFHAIA: Follow steel gauge shown on drawings for steel studs (sheet A1.3) and steel joists (sheet A2.2). Ignore the discrepancy shown on specification sheet A0.3 Division 05 Metals. 29) The flooring, acoustical ceiling tiles, and cabinets, are basically unselected- Our bid can be improved if we have more than just performance data to derive an appropriate selection from if possible. Some acceptable selections would be very convenient. Response JFHAIA: For acoustical ceiling tiles and casework/countertop a design basis is provided in specification section division # 09 Finishes and #12 Furnishings. Bid should be submitted per these base lines. Page 4

5 30) Plan page A0.6- Mid page note- All demolition work will be performed by owner. Add Alt #1- GC to perform all demolition. Verbal discussions in pre-bid meeting did not follow this description- We would like clarification if the ADD Alt #1 is for all demolition or just architectural demolition and if so, how will owner coordinate their work with GC efforts to cut and cap MEP intertwined with walls/mezzanine etc. Response JFHAIA: See response to question #1 31) Plan Page A1.1- Add Alt # 2 is a bit unclear to us. lockers not in contract GC to provide lockers Is it just locker materials affected in this line item or is does it mean materials and installation. Also, if lockers are out for the GC, should blocking be installed in new frame wall to facilitate future securement by others? Response JFHAIA: The lockers are not in contract and if requested as Alternate #2 bidders shall price the quantities of lockers. Alternate # 2 includes materials and installation. If lockers are decided to be purchased by Owner, GC should provide required blocking in new framed walls as part of base contract. 32) Plan page A2.1- detail #2- does the T1-11 siding need to be fire rated? Response JFHAIA: No. 33) Over all plan- We are concerned that there is no mention of the fire sprinklers in the plans that we could find. Specifically, there are pipes attached to the mezzanine deck that is scheduled to be removed/ replaced and logically the sprinkler heads likely need to be relocated to accommodate the new ceiling and room layout. We imagine that the county reviewers may want everything to do with the sprinkler system brought up to code with this renovation and may result in new enunciators etc. Could we get some explanatory scope as to the expectations for the sprinkler system? Response JFHAIA: See response to question #17 34) Invitation to bid-page 5 - C.2. The project must be complete no later than 75 days from award. We are concerned that this is not well designated/ defined. a. The Owner s demolition efforts could affect our completion b. Architect has no commitment for speedy review/approval of submittals. Response JFHAIA: Typical Industry standards requires contractors to allow Architects (2 weeks review time) and consultant s (additional 1 week review time) total of 3 weeks maximum. But due to a tight construction schedule we are willing to expedite and commit on review and approval of submittal in 1 week from the date of receipt. Provided GC submits a list of submittals according to priorities before starting the project. c. Plan review and approval process is included in our build time and yet we don t control design/revision efforts of architect. We would like to see the completion time be tied to or related to Owner s efforts/success to clear out work area, Owner s effort/success of demolition efforts and the issuance of the permit. We hope that our list of issues are logical and will result in clarifications that Page 5

6 will enhance the probability of VA Class A Contracting meeting or exceeding Owner s expectations should we win the bid. 35) Specifications do not ask for a urinal screen in the men's bath, but the plans show one. What material and size if one is needed? Response JFHAIA: Provide and install partition at urinal as shown on drawings. The screen should be standard toilet partition made of one of these materials High pressure Laminate/Powder coated finish aluminum/stainless steel. Size 18 to 24 wide X 48 high X 1 thickness min and should be installed 12 AFF. 36) Plans do not show bathroom trash cans, towel dispensers, mirrors or soap dispensers. Are they to be included? Response JFHAIA: All bathroom accessories, like towel, soap dispensers and mirrors should be provided and included as shown on fixture schedule on sheet A1.3 37) Is the existing decking over the bathrooms going to be left and built off of, or do you require it to be removed and replaced with new metal joist and decking? Response JFHAIA: All decking and structure above the bathroom is existing to remain as shown on Mezzanine plan A1.1 38) How will the fire sprinkler system be handled since there were no drawings indicating such? This could be a lengthy process to get engineered drawings done, submissions to the fire marshal for approval and permits. Response JFHAIA: See response to question #17. 39) Drawing A0.4 state all door hardware is dark bronze except locks say 626-brushed chrome. Please clarify the finish Response JFHAIA: All door hardware finish is to be brushed chrome, except the door closer which is indicated as dark bronze. If the closer is available in brushed chrome finish that is acceptable. END OF ADDENDUM 1 Page 6
