Design-Build Questions and Answers

Project #830-010-332, Construction of an Integrated Bioresearch Laboratory

 

Q:           If you are prequalified with CDB as a Construction Manager, but not a General Contractor can you still submit as a Design Build entity?

A:            The entity must be pre-qualified as an A/E or Contractor before the Phase I submittal deadline. Follow the instructions at the link for prequalification: http://www.illinois.gov/cdb/business/Pages/Prequalification.aspx.

Q:           Is it possible for an MEP  or Architectural consultant to be on more than one team submitting a response to the CDB Design Build Project # 830-010-332, Construction of an Integrated Bioresearch Laboratory (IBRL)?

A:            There are no restrictions against consultants submitting with multiple entities.

Q:           The document titled “SD-DB2007” for the UIUC IBRL project is a bad link on the website and I am not able to open it.  Can that be reloaded, please?

A:            The link has been fixed. The Standard Documents for Design-Build 2007 can also be found on the reference library: http://www.illinois.gov/cdb/business/library/Pages/default.aspx.

Q:           What level of commissioning will be required for the project?

A:            The University of Illinois Commissioning & Inspection Department will be responsible for commissioning the building.

Q:           Past Performance Evaluation Questionnaire:  Clarify the submittal requirements.  Are 5-7 questionnaires required for the entire team or 5 – 7 from the Offeror and 2-3 from each design team member and subcontractor?

A:            The Offeror (or lead entity) is required to submit one (1) DBQ, which lists a minimum of five (5) and a maximum of seven (7) past contracts. A minimum of two (2) projects must reflect the experience of the design team and a minimum of three (3) projects must reflect the experience of the Offeror.  The Offeror’s projects do not need to reflect the experience of the DB team collectively. The Offeror must also submit Past Performance Evaluation Questionnaires (entitled “Reference Questionnaire” on DB website) for the 5-7 contracts listed on the DBQ. Accordingly, a minimum of two (2) references will be for the design team and a minimum of three (3) references will be for the Offeror. The RFP and Reference Questionnaire will be updated by Amendment to reflect this clarification.

Q:           What is the age of the Agricultural Bioprocess Laboratory building?

A:            The Agricultural Bioprocess Laboratory was constructed in 1925.

Q:           Section 00 42 10.2, Section B. 3)  a. References:  Do the two previous project contracts reflecting the experience of the design firm need to have been completed with the design team’s proposed contractor partner for this project?

A:            No, the experience of the design team may be independent of the partner.

Q:           Section 00 42 10.2, Section C. 2) a. Discussion of project examples:  Can these be projects similar to the Integrated Bioresearch Lab project that the contractor and designer worked on with other partners?

A:            Yes.

Q:           When completing the DB Qualifications Form, are we allowed to use photos on resumes and example project pages?

A:            Project photos are acceptable for Example Projects Which Best Illustrate Proposed Team's Qualifications for This Contract. The Past Performance section is limited to 25 pages.

Q:           Is the Past Performance Evaluation Questionnaire submitted with the Phase I submittal by the Offeror or does the client/owner return directly to CDB?

A:            As stated in Section 00 42 10.2 B. 4) b. of the RFP, “Completed Performance Questionnaires shall be included with the Phase I submittal.”

Q:           RFP Section 00 21 16 .13 indicates that the A/E firm of Harley Ellis Devereaux is ineligible to compete.  Does this include other design/engineering consultants involved in the preparation of the bridging documents?

A:            Pursuant to the Design-Build Procurement Act (30 ILCS 537/20), any “design professional” as defined by Section 10 of the Design-Build Procurement Act that offered services under the  Illinois Architecture Practice Act of 1989 (225 ILCS 305/1 et seq), the Professional Engineering Practice Act of 1989 (225 ILCS 325/), the Structural Engineering Licensing Act of 1989 (225 ILCS 340/1 et seq), or the Illinois Professional Land Surveyor Act of 1989 (225 ILCS 330/1 et seq)on the preparation of the scope and performance criteria is prohibited from participating in any Design-Build entity proposal for this project.

Q:           RFP Section 00 42 10.1 B.1.d indicates “Section 4 – Financial Capability”, but there are no further clarifications on what to provide for Financial Capability (similar to the other sections). Are there any further clarifications/instructions for this section?

A:            In order to demonstrate Financial Capability, the Offeror must provide evidence of bonding capability; evidence of ability to obtain insurance; and bank references that will meet the Phase II requirements as listed in the DB-SD 2007.

Q:           RFP Section 00 42 10.2 B.3.b indicates to list major construction subcontractors (i.e. five prime trades) and since these subcontractors have not yet bid the project, we would assume we would have a list of three to six potential subcontractors bid each discipline. However, Section 00 42 10.2 B.3.c indicates for multiple subcontractors for the same discipline to only list a maximum of two subcontractors. Please confirm this is correct for listing potential subcontractors.

A:            This is correct. “Multiple subcontractors may be named for the same discipline, limited to a maximum of two (2) subcontractors per discipline.”

Q:           The CDB Design-Build Projects webpage indicates that the Standard Documents for Design-Build Projects (SD-DB 2007) is the basic “boilerplate” contract for CDB’s design-build projects and the forms related to this DB RFP. Please confirm there is no other contract document that should be reviewed.

A:            See the Sample DB Contract to be posted on the website.

Q:           RFP Section 00 21 16.8 indicates the time available for design and construction is 540 calendar days from Authorization to Proceed. Can you provide an anticipated target date for the Authorization to Proceed?

A:            Authorization to Proceed is targeted for late November to early December but no definitive date can be provided at this time.

Q:           In Section 1 - General Documents, can you please clarify who you are referring to when you ask for “each member of the DB entity”?

A:            In Section 00 42 10.2 A.2, “each member of the DB entity” refers to each vendor/firm that comprises the DB entity or “Offeror”.

Q:           Is it the CDB’s intention that D-B entities pre-select prime contractors during the Phase I submittal?

A:            Yes, Section 00 42 10.2 B.3.b states, “Offeror shall provide a list of major subcontractors and/or teaming partners to be utilized on this project.”

Q:           There is an inconsistency in the number of pages allowed for the Past Performance section of the Phase I submittal. Would CDB consider changing the page limit for Past Performance to 50 pages?

A:            The limit for Past Performance is 25 pages, exclusive of the Past Performance Evaluation Questionnaires. This discrepancy will be addressed by amendment. The page limits will not be increased.

Q:           There is an inconsistency in the number of pages for the Technical Capability. Section 00 42 10.2 C.1),2), and 3) total 12 pages maximum. Section 00 51 01.2 A. states, “The Personnel Experience section is limited to ten (10) pages.”

A:            Technical Capability is Section 3 of the Phase I submittal, and Personnel Experience section is evaluation criteria for personnel for the submittal. These two sections are not directly related. Section 00 51 01.2 A. The Personnel Experience section is limited to ten (10) pages will be addressed by amendment. Page limitations are established in Section 00 42 10.

Q:           There is a limit of using 11 x 17 as a page size for schedules only. Would CDB consider allowing 11 x 17 size paper for the organizational chart required in the DBQ as well?

A:            11 x 17 paper will only be accepted for schedules.

Q:           Phase I Evaluation Criteria states that the submittal cannot exceed fifty (50) pages, this seems inconsistent with other page limits.

A:            The Phase I submittal must not exceed fifty (50) pages in total. Edit: Section 1 – General Documents is not included in the fifty (50) pages.

Q:           Section 00 42 10.2 B.3.b and c are inconsistent with use of the term “subcontractors” and subconsultants.

A:            Section 00 42 10.2 B.3.c refers to construction subcontractors. The Section states, “Except for the design team or prime construction contractor…”

Q:           Please clarify the sections to be included in the proposal and content within each section. Clarify any page limitations for different sections.

A:            The Phase I submittal contents can be found in Section 00 42 10.2 of the RFP. Section 00 51 01 is the Phase I Evaluation Criteria and does not directly correlate to the sections of the submittal. Page limitations are spelled out in the RFP, any changes or inconsistencies will be addressed by amendment.

Q:           Do we need to submit Financial Disclosures, Standard Business Terms and Conditions and Standard Cert., and Illinois State Board of Elections Certificates from any subcontractor or design consultant we include in our proposal?

A:            Subcontractors and sub-consultants are not required to submit at this time. All members (“Primes”) of the Offeror are required to submit the documents.

 

Q:           Is Section 1 - General Documents of the Phase I submittal included in the 50 page limit?

A:            Section 1 - General Documents is not included in the 50 page limit.

Q:           Our MBE/FBE team members, especially on the design side, are prequalified with the Illinois Capital Development Board and with the Illinois Secretary of State.   Is certification with CMS an absolute requirement?

A:            Firms must be certified as MBE or FBE with CMS to meet the MBE/FBE requirement. CDB no longer recognizes IDOT certification for MBE/FBE. Firms not certified with CMS may submit to the project but will not receive credit toward the established goals.

Q:           In SD-DB Section 00 43 38.2 and Section 00 51 20.2H, both indicate the proposer shall submit a draft PC-2 form with its Phase I proposal as part of its MBE/FBE plan. However, there is no form or requirement for a draft PC-2 form in the RFP.

A:            PC-2 Forms are not required for the Phase I submittal. Please comply with Section 00 42 10.2 A.4) of the RFP for the MBE/FBE Utilization Plan.

Q:           What power requirements should be planned?  The floor plans and room data sheets show outlets and locations; however, don’t seem to address circuiting?  Should individual circuits be provided or can multiple outlets be contained on circuits?

A:            See both the U of I Facility Standards Wiring Devices Section 26 27 26/ Execution and Bridging Document Section E Item 10 through 26.

Q:           What equipment load should be used for cooling loads?

A:            The cooling loads shall be verified during design.  For proposal purposes design airflows are provided in §1.B.8 to allow the offerors to cost equipment.  These numbers are based on the original capacities which were confirmed by UIUC.

Q:           The existing laboratory has an ice storage cooling loop.  The new building will be connected to the campus chilled water loop.  The campus chilled water loop is supplied at 43F.  Will any of the new processes need temperatures colder than 43F?

A:            No.  However, a clean chilled water system for the process bay is also specified in the bridging documents.

Q:           Please designate the Authorization to Proceed (ATP) Date.

A:            As answered above, Authorization to Proceed is targeted for late November to early December but no definitive date can be provided as ATP depends on post award requirement processing.

Q:           Will the University of Illinois have a Representative for the November 7th Interview?

A:            Per the Act (Design-Build Procurement Act), the University will have a representative on the selection committee.

Q:           Will CDB provide the HED Revit Model for our use in preparing our Phase II submission?

A:            Electronic files will be posted to the CDB Website.

Q:           DI/RO Water loop:  What flow rate is expected at each connection?

A:            The design/builder shall verify flow rates at each connection during design.  Using the room data sheets as a starting point the contractor shall assume a basis for system sizing and state the basis in the proposal.

Q:           What flow rate should be planned at each connection for the following:  Compressed Air (low and high), Vacuum, Natural Gas, Chilled/Process Cooling Water, Steam (low and high), Culinary Steam?

A:            The design/builder shall verify flow rates at each connection during design.  Using the room data sheets as a starting point the contractor shall assume a basis for system sizing and state the basis in the proposal.

Q:           Glycerin:    What flow rate should be planned at each connection?

A:            The reference to glycerin in the room data sheets is in error and shall be disregarded by the offerors. This will be addressed by amendment.

Q:           In SD-DB Section 00 43 38.2 and Section 00 51 20.2H, both indicate the proposer shall submit a draft PC-2 form with its proposal as part of its MBE/FBE plan. However, there is no form or requirement for a draft PC-2 form in the RFP. Please advise if a PC-2 form needs to be submitted with Phase II submittal and, if so, what are the workforce goals?

A:            PC-2 form will be posted to the website.

Q:           Our understanding of first and second-tier suppliers that are certified on the IL Dept CMS as MBE or FBE firms is that the full value of the material they supply will contribute to our MBE/FBE construction goal when completing the Document 00 41 05. Please confirm.

A:            This is correct.

Q:           Regarding the bridging documents dwg files provided, if you turn on all the layers in the four architectural dwg files, many things become visible. For instance, electrical equipment has been placed and even circuited. H&V equipment show up also with horsepower noted. Is this additional information on the layers that were not turned on supposed to be part of the formal bridging documents? If so, will they be issued as formal pdf with the layers on we should be reviewing? Drawing L1.0 is listed on the drawing index of the Bridging Documents, but was not included in the released package. Will a pdf version be released for our use?

A:            DWG files were provided to ease the phase II proposal process. PDF’s in the file “IBRL – 830-010-332 Final Bridging Document” are the official, final bridging documents. Other layers that do not appear on the PDF’s are not part of the bridging documents. Please review item #5 of the Amendment 5.  Drawing L1.0 is part of the bridging documents will be provided by amendment.

Q:           In the CDB Standard Documents for Design-Build Projects 2007 Section 004339, Item .1 indicates that “Applicable goals for first and second level subcontractor and supplier MBE/FBE participation will be included in the RFP.”  In the RFP for the UIUC IBRL project, Section 004210, Item .2.A.4.a indicates that the MBE/FBE construction goals “include both Tier 1 and Tier 2 subcontractors.”  Please confirm that Tier 1 and Tier 2 suppliers are also allowed to be included towards the participation goals.  Also, is the use of Tier 2 subcontractors and suppliers toward the participation goals allowed for all scopes of work, or is it limited to MEP subcontractors such as used under the “Single Prime with Protected Subcontractors” project delivery method?

A:            Yes, tier 1 and tier 2 subs/suppliers are acceptable for all scopes.

Q:           Could you please clarify if the Design-Builder / Proposer is required to Supply and Install all Furniture, Equipment, Computers etc. noted on the Room Data Sheets?

A:            Refer to Section F of Volume 1 of the Project Manual. Design-Builder is to design/coordinate and install the Owner-purchased “Furnishings” and “Office Equipment” as described under Part 3. 

Q:           Regarding Bridging Document page E-4, subparagraph "10. Redundancy" (1,2,3, Q1-Q10):

1.       The column titled "Redundancy" is understood to mean "Quantity of components to be provided".

A:   Correct.

2.       Then "N+1" is understood to mean to "Provide a quantity (N) of the listed equipment equally sized components which have the capacity to satisfy 100% of the design load. Provide at least one additional independent backup component (+1) of the same capacity as the N components."

 

A:  No.  The term N+1 requires that more than one piece of equipment provide the full system capacity.  It does not require full redundancy, such as 2N.  See below for the additional capacity required for each piece.

 

3.       Then the note "N+1 < 133%" is understood to mean to "Provide a quantity (N) of the listed equipment equally sized components which have the capacity to satisfy 100% of the design load. Provide at least one additional independent backup component (+1) of the same capacity as the N components such that the size of any one component is not greater than 33% of the design load."

A:  No.  Each piece of equipment (i.e. fan, pump, etc.) shall be sized so that the total capacity of all of the devices is 133% of the required duty for the system.  For example, if an exhaust system requires 10,000 cfm, two fans shall be provided with a duty of 6,650 cfm.  This would be similar for the fans associated with an air handler.  Full redundancy would be defined as “2N”.

 

                Q1:         Q1: Are the above three understandings correct?

A:            No.

Q2:         Should the note "N+1 < 133%" be applied to the entry "Heating Water Pumps"? This would require four very small pumps, each sized at 33% of the design flowrate, be provided. 

A:            Yes.  The glycol and heating water system will require two pumps at 2/3 of the full system capacity.

Q3:         Should the note "N+1 < 133%" be applied to the entry "Supply Fans" for AHU-1? This would require four small fans, each sized at 33% of the design flowrate, be provided for AHU-1 in a fan array arrangement. 

Note that if the project would be agreeable to housed centrifugal fans for the three AHUs then the note "N+1 < 133%" should be removed from the table for the Supply fan entry.

A:            Yes, but requires, minimally, two fans, sized for 2/3 of the system capacity.  More fans can be provided but the total capacity should be at 133% of the required system capacity.  Additional capacity can be provided, but the minimum total capacity is 133% of the system duty.

                A single housed centrifugal will not satisfy the redundancy requirement.  This would be an exception to the bidding requirements and should be noted in the proposal.

Q4:         Note that UIUC 23 73 23 2.15.A.5.c implies that any arrangement with N+1 fans is a "critical application" requiring dedicated VFD and automated discharge damper for each fan. So a "N+1 < 133%" table entry would require four VFDs and four actuated dampers to match the four supply fans. Consider using the "N+1 < 133%" table entry note only on those AHUs required to have supply fan arrays.

Should AHU-1 with an N+1 entry be considered a critical fan per 23 73 23 2.15.A.5.c?

                A:            AHU-1 is associated with the office and would not be considered critical.

                Q5:         Should AHU-2 with an N+1 entry be considered a critical fan per 23 73 23 2.15.A.5.c?

                A:            AHU-2 is deemed critical.

                Q6:         Should AHU-3 with an N+1 entry be considered a critical fan per 23 73 23 2.15.A.5.c?

                A:            AHU-3 is deemed critical.

Q7:         Should the note "N+1 < 133%" be applied to the entry "Lab Exhaust Fan"? This would require four fans, each sized at 33% of the design flowrate, be provided for each of the two lab exhaust systems.  To locate such an fan array arrangement outdoors next to the two penthouses would appear to be an uncommon arrangement.

A:            This can be designed as two fans, each sized with a capacity 2/3 of the system duty.

Q8:         Should the "Lab Exhaust Fan" entry apply to the general exhaust fan system serving the Analytical Lab exhaust taken from the occupant's breathing space? It is understood that the Fume Hood exhaust system is a "Lab exhaust fan" and will be "high plume, induction-type complete with bypass plenum and dilution nozzles" as note on page E-10 of the Bridging Document. Two fans sized at 100% capacity would be a common arrangement.

A:            The exhaust fans shall be sized as explained above.

Q9:         Is the Volatile Extraction room 136 exhaust fan noted on page E-21 of the Bridging Document to be considered a "process exhaust fan" as noted on E-10? If yes, the Volatile Extraction Exhaust fan would be furnished as "high plume, induction-type complete with bypass plenum and dilution nozzles" which is "spark-resistant".

A:            Correct.

Q10:       For the Volatile Extraction fan system, is AMCA "C" spark resistant an acceptable level of spark resistance?

A:            This is a minimum level of spark resistance, and is acceptable.  Please clearly note the specification for the fans in the proposal.

 

Q:           Section E, page 38, under Section 8 Emergency Generator states "The generators will be sized to accommodate the entire building load...". Is the intent to have the generator serve the entire building or just essential loads that are defined?           

A:            This shall be confirmed during design by the design/build contractor.

Q:           Regarding the requirements on the Lab Data Sheets for the Processing Bay: There are some discrepancies with language in the Bridging Document narrative with regard to different steam utilities required at Utility Stations. Data Sheet lists Hi Pressure Steam (80 psi), but narrative mentions 60 psi. Data Sheet lists Low pressure steam (no specific PSI delivery) and narrative doesn’t appear to list any low pressure steam, at least with regard to Processing Bay other than AHU steam and humidification. Please provide confirmation as to what is correct or which are we to follow. We know that we are very early in the design stage, but there are no sizing of pipes, so there is no way to know how much steam is being generated or used at these locations or for any processes. Also, the utility stations make no mention of condensate return for any of the steam to those locations and we would have to assume there needs to be one for each type of steam being delivered.

A:            The steam pressures are listed in Section E as follows:

Low pressure (12 PSIG) shall be provided for the hot water generator, the glycol heating water generator, and the domestic water heater. High pressure steam (145 PSIG) shall be provided for the culinary steam system.  The culinary steam is delivered at 60 psig.  The room data sheet. 

The high pressure steam listed in the data sheet for the Processing Bay refers to campus high pressure steam that has been regulated down to 80 psig.  The low pressure steam listed is delivered at 12 psig.

Condensate will be returned form high and low pressure steam systems.  The culinary steam system will not include a condensate return system.

Q:           Can we get a detail or sketch of the incoming medium voltage ductbank that will meet U of I specifications?  Are we allowed to directional bore this installation to save costs?

A:            A sketch will not be provided at this time.  No, the primary service is to be installed in a concrete duct bank.

Q:           No specific switchgear manufacturer is listed. Since the project will need digital metering, Tri-City is assuming that the University has a preferred system which they would like to keep consistent with. Based on their experience with universities and multiple building installations, the digital metering is preferred to stay the same for maintenance staff. Please provide this info.

A:            Please refer to The Universities Electrical Metering Standards, Section 26 27 13.

Q:           Can we get a drawing or sketch for the Communications ductbank design? Are we allowed to directional bore this installation to save costs?

A:            The University Standards, located in the Facilities web site, are standard details for underground communication conduit.   No.  Please follow the details using spacers, and concrete encasement.

Q:           Which document takes precedence for scope of work between the Section E narrative and the Volume 2 - Appendix A Room Data Sheets? For example, in the Processing Bay (room 135), Section E, page 41, item 23.c calls for four (4) 208v, 30 amp and four (4) 120v, 20 amp overhead receptacles in each quadrant, while the room data sheet in Appendix A only calls for one (1) 208v, 30 amp overhead receptacle in each quadrant.

A:            Follow both requirements but when there is a conflict use the direction which requires more devices or is more restrictive. In this case follow Section E.

Q:           The lighting levels indicated on the Room Data Sheets are way over than IESNA recommendations. Do we need to provide lighting levels indicated on Room Data Sheets or follow IESNA recommendations?

A:            The room data sheets shall be used for the proposal.  The lighting levels shall be confirmed during design by the design/build contractor.

Q:           The Bridging document  Section E Part III Para D, 8 indicates generator size should accommodate entire building power while in other paragraphs indicates provide some receptacles on generator power. Is generator required to backup entire building or curtains portion of the building only?

A:            This shall be confirmed during design by the design/build contractor.

Q:           Can the CDB confirm that the project is still registered under LEED v. 2.2? The GBCI reserves the right to revoke registration if there is an extended period of inactivity on the LEEDOnline portal. If the project registration has been revoked, the project will likely have to comply with LEED 4.0 which will have a substantial impact on the project design. There are significant changes to the energy and atmosphere (energy savings) that would greatly affect the program.

A:            The project is registered under LEED 2.2.

Q:           The RFP asks that the narrative reflect setback requirements, however, no setbacks are shown on the civil bridging documents.  Provide setback information.

A:            If there are not any setback requirements shown, then the narrative should reflect that. The building is located on the site by N/E, as shown on the civil drawings.  The University's FS2 standards do not require specific setbacks so I would think these defer to local municipality codes, and the designer should confirm these requirements during design.

Q:           The bridging documents suggest using the 8,000 gallon storm water management vault to provide rainwater harvesting for irrigation.  The quantity of irrigation water to be stored is not clearly specified.  However the storm water management volume and the irrigation storage column cannot be stored in the same facility without negating the intended peak storm water flow attenuation unless there is a system in place to evacuate the irrigation water in anticipation of a storm.  There are three possible scenarios:

a.            Construct a separate rainwater harvesting tank on site or in the building.

b.            Incorporate smart technology into a combines system that will manage the volume of rainwater stored compared to the anticipated storm flow.

c.             Eliminate the rainwater harvesting system entirely.

Please provide clarification.

A:            There is no requirement for a rainwater harvesting system.  The tank is currently listed to show a total size, mainly for the purpose of cost inclusion as well as site space allocation.  Per direction from the University this tank will be accessed by a roaming landscape crew that will use a hose and pump to utilize this water for landscaping.  The tank's size includes the volume increase for the 100-year peak discharge plus the 2-year storm volume to meet LEED SS6.1 objectives.  If the designer feels they can achieve the required LEED certification without this point the tank may be reduced to only handle the increase to the peak 100-year storm event.  The tank should be designed with a restricted release rate so as not to exceed the existing 100-year peak discharge, as this is the critical flow.  The 2-year storm event will be discharged at a smaller rate due to the decreased high water level elevation within the tank.

Q:           On the plan, there is a #64 sterilizer listed (freestanding) and an autoclave listed on the bench (#67).  The only description in the equipment data sheet for the autoclave is for a freestanding size (item G) and there is no sterilizer listed/described.

Is the sterilizer #64 meant to be the autoclave, and if so, what are the requirements for #67 bench top autoclave.  Please clarify.

A:            The bench top autoclave is to be deleted and the autoclave is to be located where the sterilizer is shown. The autoclave requirements listed in the bridging documents, ‘Note G of the equipment matrix’, do not change.

Q:           On the water system, the drawings say connect to City of Urbana 12” water main. The City is not a supplier of water. It is either U of I water or Illinois American Water Co. I believe this to be a U of I main which could be run into the building and split for fire and domestic. If it is an Illinois American Water Co. main, we have to take separate fire and domestic lines into the building as well as provide a detector check assembly outside the building.  Please clarify who is the Water Supply Source.

A:            The water main is owned by the University of Illinois.  This has been confirmed with Illinois American Water Company; they do not own a 12" main within Pennsylvania Avenue.  They do own a 6" water main in Pennsylvania Avenue but terminates at S. Virginia Drive, approximately 1,000 LF east of our project site.

Q:           We assume that we do not need to include any campus utility facility costs associated connection, tap and usage of campus utilities.  For example, we assume there is not a one-time facility charge to connect the building to the campus chilled water system and that there is not a charge to use the chilled water for temporary construction cooling, if required,  Please confirm.  If there are charges, please advise to the amounts and/or rates that we would need to include.

A:            The Design-Builder is required to pay for CHW usage.  Also, no CHW usage is permitted unless a working and verified CHW meter is in place to record usage. Rates should be verified by UIUC.

Q:           We cannot locate 5/H4.4 referenced on S1.0 regarding trench drains.

A:            This detail reference should be disregarded, modifications to Sheet S1.0, clarifying the detail references, will be issued.

Q:           Bridging Document Section E - Services, Part II, Para A, 5, h, iii - “Transformer New outdoor, less flammable/nontoxic oil cooled, pad mounted transformer. Match the campus primary voltage of 12470 Volts and secondary voltage of 480/277 Volts, Three (3) Phase, Four (4) wire. Transformer shall have bayonet style current limiting fuses.
