June 19, 2023: Vendor questions deadline; (questions and requests for clarification must be submitted via
email to: Scott Babich, scottb@kcranch.org) Objective
The Ken-Caryl Ranch Metropolitan District is a special district providing parks and recreation services to a community
of approximately 11,000 residents in Littleton, Colorado. The CLIENT is governed by a five-member Board of Directors
with day to day operations managed by the District staff.
If CLIENT, in its sole discretion, identifies and selects a qualified vendor, CLIENT's selection is conditioned on the parties
entering into a mutually acceptable contract. In addition to setting forth the scope of work/services, compensation
and standard contract provisions, the contract will contain provisions concerning: nonappropriation, governmental
immunity, and workers without authorization. Required Scope of Work
Firms are required to provide the following scope of work:
PRESSURE WASH existing roof to achieve a clean surface free of dirt, rust, corrosion, residues, and other
coatings or contaminants.
FASTENERS, screws, and any other fastening devices will first be tightened and/or replaced so that all metal
sections are firmly held in place and all joining sections closed.
PRIME FASTENERS and any other rusted and/or corroded surfaces. Scaling and pitted rust will first be
removed by scraping or by mechanical wire brush. Priming with an anti-corrosive to make sound, clean and
dry roof surface at a minimum coverage rate 300sf/gal per coat over the rusted areas.
CAULK all exposed cracks and seams over 1/8" in width with an Acrylic Latex Caulk. A sealer will be applied
over gaps and cracks 1/8" or less in width.
WATERPROOF fasteners by encapsulating the base of fastener heads with an acrylic sealer, WATERPROOF
horizontal seams, and flashings with 4" wide polyester cloth embedded into an 8" wide coat of rolled sealer.
Install expansion control joints and flashings use 4" or wider strips on joints, flashings, and repair areas. In all
cases cloth will be applied with a brush or roller to avoid wrinkles or gaps between the material and the
surface. We will then cover the polyester cloth with a second coat of sealer overlapping 2" on each side at an
average rate of 82sf/gal.
WATERPROOF vertical seams by using 2" wide polyester cloth strips embedded in a 4" wide wet coat of
sealer spread along the seams. Cloth will then be covered with a second coat of sealer overlapping 1" on
each side at an average rate of 82sf/gal.
INSPECT SURFACE AREA again to be sure it is clean and dry. The dried membrane must be free of all
moisture; dirt, dust, and debris before applying the ceramic finish coats.
APPLY PROTECTIVE COAT at a rate of 148sf/gal over the dried membrane covering joints, flashing, and repair
areas. This protective coat will be applied in addition to and before the ceramic finish coats.
APPLY FIRST COAT over the entire roof surface and roof protrusions at an approximate coverage rate of 148
sf/gal to lower substrate surface temperature and to improve the rate of curing and the quality of the
finished appearance.
APPLY CERAMIC FINISH COAT by brush, roller or spray over the entire roof surface and roof protrusions at an
approximate coverage rate of 148 sf/ gal. The Ceramic Coating applied in these multiple passes will result in
monolithically covering the entire surface with a fully cured film having a minimal dry thickness of twelve (12-
14) mils realized from two applications of ceramic coating at a combined minimum coverage rate of 74 sf/
gal. The complete Waterproof and Insulating Coating System (all specified coatings and cloth) will
additionally over all termination points, seams, and flashings, at an average dry thickness of 45 mils.
