EXHIBIT 2 – QUESTIONS & ANSWERS
1. Why are Hip Vents called out if we are using top-vented Therma-Cal 1 system by Cornell
Corporation?
Answer: The Hip Vents are to be eliminated since we have called out for vertical and
lateral venting with the Therma-Cal 1 system.
2. Request approval to use Atlas and Carlisle Roofing Insulation for the Rigid
Polyisocyancurate Board Insulation.
Answer: These are acceptable manufactures for the rigid insulation. The product is to
meet the requirements specified.
3. What is the wind rating to be used to anchor the nail base for the roofing system?
Answer: The City of Fort Collins requires a system designed to withstand a 100 MPH
wind. The fasteners for the nail base will need to be installed per the manufactures
recommendation to meet this requirement.
4. The plans note ¾” OSB and the specifications mention 5/8” sheathing under installation,
which is correct?
Answer: ¾” FlameBlock OSB is the sheathing to be installed under the base bid.
5. The specifications state FlameBlock for the OSB Sheathing, is this to be applied to one
side or both?
Answer: Apply FlameBlock to the top side of the ¾” OSB Sheathing
6. Is there additional blocking that will be needed behind the gutters with them raised up?
Answer: Yes there will need to be some blocking added for the gutter in the new
location. We have attached the roof details from the original building and a revised detail
showing this blocking. The contractor will need to paint a section of the facia metal to
match existing once the gutter is installed at the new location.

EXHIBIT 3 – PREBID MEETING AGENDA
October 24, 2012
RE: Fort Collins Senior Center West Wing Re-Roof Pre-Bid Meeting
Agenda
1. Project Description
A. Base Bid - Removal of existing gutters and downspouts on west wing and salvage
for re-use. Removal of existing roofing on west wing down to metal decking and
replacement with new vented insulation system with 30 year asphalt shingles.
B. Alternate 1 - Removal of existing gutters and downspouts on west wing and salvage
for re-use. Removal of existing roofing on west wing down to metal decking and
replacement with new insulation and OSB sheathing with 30 year asphalt shingles.
2. Availability of Site
Site is available from 7:00 am to 6:00 pm but the building interior is off limits to roofing
crews.
3. Project Time line & Phasing
1. Addenda Issued (if necessary) – October 26, 2012
2. Project Bid Date – November 1, 2012
3. Award Project – As Soon As Possible
4. Work to begin – Late November
5. Completion – 150 Days from Notice to Proceed
The plan is to complete the roof over the swimming pool area this fall as a minimum
because the existing roof is in poor shape and has temporary patches installed and will
not make it through the winter without additional patching. The balance of the remaining
roof will be completed as weather allows, but must be completed within the timeline in
the bid documents. We are currently working to design an addition on to the west wing
and hope to have an idea of how this may connect by February. A portion of the re-roof
maybe delayed or eliminated to avoid doing the roofing at the new addition tie-in twice.
The south gym area will need to be delayed until spring 2013 after we know the scope of
the new addition.
4. Sustainability
A. All City of Fort Collins projects are to be completed looking at the sustainability and
using green building materials.

7. Work Restrictions
All roofing work must be coordinated with facility management due to the noise that will
be incurred and the various activities they have scheduled.
8. Communication
We will have a pre-construction meeting prior to starting work to discuss preliminary
schedule for this project and we will have a weekly meeting to address issues and
scheduling changes. All bidding questions need to come through procurement.
9. Use of Site During Construction
Roofing crews will have access to the parking lot on the west end for dumpster, material
storage and vehicles.
10. Protection of Existing Facilities
All existing paving, walks, landscaping and building shall be protected from damage
while completing this work.

APPENDIX J
Construction, Deconstruction Or Demolition Waste Diversion
This policy applies to waste material generated from the construction,
deconstruction, or demolition of City of Fort Collins facility projects.
Purpose: To divert the maximum amount of building materials from the waste
stream and reduce the demand for new materials - thus decreasing the
environmental impact of providing those materials. Priority is to reuse materials in
new or existing structures. Those materials not suitable for reuse shall be
recycled - as feasible. Sending material to a landfill is a last resort. (Hazardous
material is an exception.) Relocating and using a structure at another site is a
method of reuse.
Background: In the context of physical construction, deconstruction is the
selective dismantlement of building components, specifically for re-use, recycling,
and waste management. It differs from demolition where a site is cleared of its
building by the most expedient means. Deconstruction has also been defined as
“construction in reverse.” The process of dismantling structures is an ancient
activity that has been revived by the growing field of sustainable, green building.
Buildings, like everything, have a life cycle. Deconstruction focuses on giving the
materials within a building a new life once the building as a whole can no longer
continue.
When buildings reach the end of their useful life, they are typically demolished
and hauled to landfills. Building implosions or ‘wrecking-ball’ style demolitions are
relatively inexpensive and offer a quick method of clearing sites for new
structures. On the other hand, these methods create substantial amounts of
waste. Components within old buildings may still be valuable, sometimes more
valuable than at the time the building was constructed. Deconstruction is a
method of harvesting what is commonly considered “waste” and reclaiming it into
useful building material.
A major difference between construction debris and deconstruction/demolition
(D/D) debris is that construction debris tends to be cleaner and more easily
separated. D/D materials typically tend to be from older facilities, so
contaminants such as asbestos, lead based finishes, mercury, and PCB's
complicates there reuse and recycling.
Policies, Procedures, and Guidelines:
1. City project managers are responsible for communicating the policies for
waste diversion to contractors and subcontractors performing construction,
deconstruction & demolition work. Project managers of projects that generate

Addendum 1

J-2
large amounts of debris and waste material shall work closely with the City’s
Natural Resources Department (NRD) to ensure diversion meets specific City of
Fort Collins goals.
2. For a D/D project, an environmental assessment and proper removal of any
identified hazardous materials is required prior to further work.
3. Contractors and/or project managers must obtain all appropriate permits.
4. Diversion goals: New building construction waste diversion must adhere to the
Leadership in Energy and Environmental Design (LEED) Gold diversion ratings.
Deconstruction and demolition projects should achieve 100% diversion of
materials such as concrete, rock, asphalt, dirt, bricks, and metals and at least
70% diversion of all remaining materials by weight or volume through source
separation of reuse, recyclable or salvageable materials.
5. City’s request for proposals (RFP) and contracts for these projects shall
require the submission of a recycling, reuse, and disposal plan to the project
manager for approval. To measure compliance, the plan shall include tracking of
salvaged, recycled and waste materials be documented on a form similar to
attachment one. Copies of receipts and/or weight tickets may also be required. A
copy of the tracking form shall be provided to Natural Resources Department.
6. City contractors violating the City’s diversion policy may be barred from City of
Fort Collins construction, deconstruction or demolition contracts for a period of
two years.
7. In the event of a natural or other disaster, the diversion goals as stated above
shall apply to any/all disaster relief cleanup efforts unless modified by the Natural
Resources Department.
8. The Natural Resources Department, in concert with the project managers, will
maintain a construction, deconstruction, and demolition waste “best practices”
manual with an annually updated list of recycling and reuse options.
9. A diversion cost analysis will be conducted on larger projects (>$50,000) to
determine if deconstruction is not cost prohibited along with a determination of
project time requirement and if the facility is suitability for deconstruction.
