Summary Title: Rinconada Pool Building Roofing Replacement Project
Title: Approval of a Construction Contract With Alcal Specialty Contracting,
Inc. in an Amount Not-to-Exceed $261,227 to Replace the Existing Roofs at
the Rinconada Pool Buildings, Capital Improvement Program Project PF-
00006
From: City Manager
Lead Department: Public Works
Recommendation
Staff recommends that Council:
1.Approve and authorize the City Manager or his designee to execute a
contract with Alcal Specialty Contracting, Inc. in an amount not to exceed
$237,479 (Attachment A) for the Rinconada Pool Roofing Replacement
project, budgeted in the recurring Capital Improvement Project, Roof
Replacements (PF-00006); and
2.Authorize the City Manager or his designee to negotiate and execute one or
more changes to the contract with Alcal Specialty Contracting, Inc. for
related additional but unforeseen work, which may develop during the
project, the total value of which shall not exceed $23,748.
Background
The existing mineral cap sheet roof on the Rinconada Pool is beyond its useful life
and no longer meets code or Title 24 requirements. Leaking has caused extensive
water damage throughout the entrance lobby, locker rooms and shower areas,
increasing maintenance needs both to the roof and affected interior spaces.
Discussion
This project will improve occupant health and safety and reduce maintenance
costs. Under contract, Alcal Specialty Contracting, Inc. will remove the existing
City of Palo Alto Page 2
mineral cap sheet roofing system down to the wood deck substrate, and the
equipment from its current curb supports. Curbs will then be dismantled and
rebuilt higher and the equipment reinstalled per the specifications (Attachment
B).
Alcal Specialty Contracting, Inc. will provide and install a modified bituminous
membrane roofing system throughout with R-9 insulation, new crickets and
drainage swells to direct rainwater to new roof drains, and walkway traffic pads
to access rooftop mechanical equipment.

2017. The bid period was 19 calendar days. Ten bids were received on February
28, 2017,five of which were from responsible and responsive bidders

certain portions of the Work, reserving to itself all rights to Losses related thereto.
Invitation for Bid (IFB) Package 13 Rev. March 17, 2017
CONSTRUCTION CONTRACT
15.1.2 Perform and Withhold. City may, without terminating the Construction Contract, engage
others to perform the Work or portion of the Work that has not been adequately performed by
Contractor and withhold the cost thereof to City from future payments to Contractor, reserving to
itself all rights to Losses related thereto.
15.1.3 Suspend The Construction Contract. City may, without terminating the Construction
Contract and reserving to itself all rights to Losses related thereto, suspend all or any portion of
this Construction Contract for as long a period of time as City determines, in its sole discretion,
appropriate, in which event City shall have no obligation to adjust the Contract Sum or Contract
Time, and shall have no liability to Contractor for damages if City directs Contractor to resume
Work.
15.1.4 Terminate the Construction Contract for Default. City shall have the right to terminate
this Construction Contract, in whole or in part, upon the failure of Contractor to promptly cure
any default as required by Section 14. City’s election to terminate the Construction Contract for
default shall be communicated by giving Contractor a written notice of termination in the manner
specified for the giving of notices in the Construction Contract. Any notice of termination given to
Contractor by City shall be effective immediately, unless otherwise provided therein.
15.1.5 Invoke the Performance Bond. City may, with or without terminating the Construction
Contract and reserving to itself all rights to Losses related thereto, exercise its rights under the
Performance Bond.
15.1.6 Additional Provisions. All of City’s rights and remedies under this Construction Contract
are cumulative, and shall be in addition to those rights and remedies available in law or in equity.
Designation in the Contract Documents of certain breaches as material shall not waive the City’s
authority to designate other breaches as material nor limit City’s right to terminate the
Construction Contract, or prevent the City from terminating the Agreement for breaches that are
not material. City’s determination of whether there has been noncompliance with the
Construction Contract so as to warrant exercise by City of its rights and remedies for default under
the Construction Contract, shall be binding on all parties. No termination or action taken by City
after such termination shall prejudice any other rights or remedies of City provided by law or
equity or by the Contract Documents upon such termination; and City may proceed against
Contractor to recover all liquidated damages and Losses suffered by City.
15.2 Delays by Sureties.
Time being of the essence in the performance of the Work, if Contractor’s surety fails to arrange for
completion of the Work in accordance with the Performance Bond, within seven (7) calendar days from the
date of the notice of termination, Contractor’s surety shall be deemed to have waived its right to complete
the Work under the Contract, and City may immediately make arrangements for the completion of the
Work through use of its own forces, by hiring a replacement contractor, or by any other means that City
determines advisable under the circumstances. Contractor and its surety shall be jointly and severally
liable for any additional cost incurred by City to complete the Work following termination. In addition, City
shall have the right to use any materials, supplies, and equipment belonging to Contractor and located at
the Worksite for the purposes of completing the remaining Work.
Invitation for Bid (IFB) Package 14 Rev. March 17, 2017
CONSTRUCTION CONTRACT
15.3 Damages to City.
15.3.1 For Contractor's Default. City will be entitled to recovery of all Losses under law or
equity in the event of Contractor’s default under the Contract Documents.
15.3.2 Compensation for Losses. In the event that City's Losses arise from Contractor’s default
under the Contract Documents, City shall be entitled to deduct the cost of such Losses from
monies otherwise payable to Contractor. If the Losses incurred by City exceed the amount
payable, Contractor shall be liable to City for the difference and shall promptly remit same to City.
15.4 Suspension by City
15.4.1 Suspension for Convenience. City may, at any time and from time to time, without
cause, order Contractor, in writing, to suspend, delay, or interrupt the Work in whole or in part for
such period of time, up to an aggregate of fifty percent (50%) of the Contract Time. The order
shall be specifically identified as a Suspension Order by City. Upon receipt of a Suspension Order,
Contractor shall, at City’s expense, comply with the order and take all reasonable steps to
minimize costs allocable to the Work covered by the Suspension Order. During the Suspension or
extension of the Suspension, if any, City shall either cancel the Suspension Order or, by Change
Order, delete the Work covered by the Suspension Order. If a Suspension Order is canceled or
expires, Contractor shall resume and continue with the Work. A Change Order will be issued to
cover any adjustments of the Contract Sum or the Contract Time necessarily caused by such
suspension. A Suspension Order shall not be the exclusive method for City to stop the Work.
15.4.2 Suspension for Cause. In addition to all other remedies available to City, if Contractor
fails to perform or correct work in accordance with the Contract Documents, City may
immediately order the Work, or any portion thereof, suspended until the cause for the suspension
has been eliminated to City’s satisfaction. Contractor shall not be entitled to an increase in
Contract Time or Contract Price for a suspension occasioned by Contractor’s failure to comply
with the Contract Documents. City’s right to suspend the Work shall not give rise to a duty to
suspend the Work, and City’s failure to suspend the Work shall not constitute a defense to
Contractor’s failure to comply with the requirements of the Contract Documents.
15.5 Termination Without Cause.
City may, at its sole discretion and without cause, terminate this Construction Contract in part or in whole
upon written notice to Contractor. Upon receipt of such notice, Contractor shall, at City’s expense, comply
with the notice and take all reasonable steps to minimize costs to close out and demobilize. The

The asphalt must not be overheated to compensate for cold conditions. The use of insulated handling equipment is strongly recommended. Hot luggers, mop carts, and kettle-to-roof supply lines should be insulated. Hand mops should be constructed with a smaller yarn head to facilitate short moppings. Luggers and mop carts should never be more than half filled at all times. 3. Temperature Restrictions - cold adhesive: At low temperatures, the specified cold adhesive becomes more viscous, making even distribution more difficult. The optimal temperature of the adhesive at point of application is 70° - 100°F (21° - 38°C). To facilitate application when ambient temperatures are below 50F (10C), store the adhesive and roll goods in a warm place immediately prior to use. Bulk warmers, inline heaters, or other pre-heating equipment should be used to maintain the proper viscosity of the adhesive when using mechanical application equipment. Consider "flying in” the pre-cut roofing sheets in by placing them into the adhesive rather than rolling them into position. Roll or broom the sheets to ensure contact with the underlying adhesive. Suspend application in situations where the adhesive cannot be kept at temperatures allowing for even distribution. 4. Temperature Restrictions - self-adhered: The minimum required substrate temperature at point of application is 40F (4C). Maintain a minimum roof membrane material temperature above 60° F (16° C). In low temperature conditions, materials should be kept warm prior to application. In temperatures below 60° F (16° C) the specified tacky primer, required for vertical applications, should be considered to facilitate proper bonding of self-adhered membrane for horizontal applications. The minimum ambient temperature range at the time of tacky primer application is 45°F to 105°F (7°C - 40°C). Suspend application in situations where the self-adhered base ply cannot be

kept at temperatures allowing for proper adhesion.

patterns.
4. QUALITY ASSURANCE
A. Railings Structural Requirements: 1. Handrail, wall rail and guardrail assemblies and attachments shall
withstand a minimum concentrated load of 200 pounds (90719 g)
applied in any direction on the top rail.
2. Infill area of guardrail system capable of withstanding a horizontal concentrated load of 200 pounds (90719 g) applied to one square foot (8165 g/sm) at any point in the system. Load not to act
concurrently with loads on top rail of system in determining stress
on guardrail.
B. Hole covers: 1. Covers and protect holes: gaps or voids 2 inches or more in its least dimension in a floor, roof, deck, or other walking/working
Rinconada Pool Bldgs Re-Roof Specification PF-00006
Section 07 72 69
Page 3
surface.
i. Workers can fall through holes.
ii. The hole’s design can create a trip hazard.
iii. Objects can fall through the hole and injure workers below. iv. Holes can be cut (or constructed) in floor to receive
equipment or ducts and for future access points (e.g.
opening for stairs that will be installed later.)
v. Holes can be cut in roofs in preparation for installing
skylights, ventilation units, and other features and equipment.
2. Covers are strong protective surfaces used on walking/working
surfaces or roadways to prevent workers from falling through a
hole.
i. Covers for permanent holes are typically built for a specific purpose (e.g., permanent access points, manhole covers,
and trap doors) and are only effective when they are
properly designed and secured in place.
ii. Covers for temporary holes are often constructed on work
sites with reusable materials, most commonly using plywood and steel plates. For example, to cover large holes in a road,
hinged steel plate covers can be used. Other options for
covers include grates designed to support weight, custom
boxes to cover a hole with an elevated lip or partially
installed equipment, and temporary trapdoors. 3. Heavy plywood is a common choice for covering temporary holes in
floors and roofs, but plywood strength and durability can vary.
i. Approved plywood rating systems: APA–The Engineered
Wood Association (formerly the American Plywood
Association and Douglas Fir Plywood Association) and the Timber Engineering Company (TECO). CSHOs should
refer to these organizations for detailed information.
ii. Use only exterior-grade plywood at areas where workers are
using hauling equipment, to prevent damage to the flooring
from concentrated loads. Typical protective layers may include liquid latex compounds, penetrating oils, sheet plastics, and interlocking membranes.
iii. Plywood covers rest on the hole edges that are supported
through the joists. Plywood piece must be large than the
hole, overlapping the support surfaces and positioned with the grain direction running along the shortest unsupported hole dimension.
Rinconada Pool Bldgs Re-Roof Specification PF-00006
Section 07 72 69
Page 4
C. Warning or Marking Systems:
1. A warning line system is a barrier erected on a flat or low- sloped
roof to warn workers that they are approaching an unprotected roof
side or edge. They must be established before work begins. All workers must be trained for these requirements.
i. Warning lines are not engineered to physically prevent or
arrest falls and may not be used in all situations. They must
remain between34 – 39” above the roof level and have a
minimum tensile strength of 500 lbs. Lines must be installed so that one section of line will not cause stanchions to tip
over.
ii. On flat or low-sloped roofs, warning lines are used in
conjunction with conventional fall protection or a safety
monitoring system. They must be installed at least 6’ back from edges (10 feet when mechanical equipment is used.)
iii. Workers are not allowed in the area between the warning
line and the unprotected edge, except during roofing work.
iv. Any employee performing roofing work between the warning
line and the roof edge must be protected using another form of fall protection.
2. A safety monitoring system uses a competent person as a safety
monitor who can recognize and warn workers of fall hazards.
i. Safety monitoring systems are typically used as part of fall
protection plans during precast concrete erection work, leading edge work, and residential construction work when
conventional fall protection is infeasible or would create a
greater hazard and alternative measures (such as
scaffolds, ladders, or vehicle mounted work platforms) are
not used. ii. Also, when conducting roofing work on a flat or low sloped
roof that is 50 feet or less in width, a safety monitoring
system may be used as a standalone fall protection
technique. Large roofs can be broken in sections.
iii. Only workers engaged in low-sloped roofing work and workers performing the specific job tasks covered by a fall protection plan are allowed in an area where workers are
being protected by a safety monitoring system.
iv. The worker designated as the safety monitor may not
perform other job tasks that could take attention away from the monitoring function. He/she shall be competent to recognize fall hazards, establishes the procedures to
protect, has to be on the same surface and within sight of
Rinconada Pool Bldgs Re-Roof Specification PF-00006
Section 07 72 69
Page 5
the workers, and be close enough to orally communicate
with the workers.
D. Access Zoning:
1. A controlled access zone (CAZ) is a clearly marked, designated work area where certain work (e.g., overhand bricklaying) may take
place without conventional fall protection systems.
i. They are used to keep out workers other than those
authorized to enter a work area.
ii. Situations where CAZs are used include overhand bricklaying and related work (provided that workers are not
reaching more than 10 inches below the walking or working
level they are on), leading edge work, and precast concrete
erection (both used when conventional fall protection is
infeasible or creates a greater hazard.) iii. Control lines are used to demark CAZs
2. A controlled decking zone (CDZ) is a clearly marked work area
used during steel erection while workers are initially installing
decking at the leading edge of the work area.
E. Fall Restraint Systems and Positioning Devices:
1. System or device shall withstand at minimum a concentrated load
of 3,000 pounds of force or twice the maximum expected force that
is needed to restrain the worker from exposure to the fall hazard.
2. Positioning devices are specialized systems that hold workers in place on an elevated vertical surface (such as a wall) allowing them
to keep both hands free to work while leaning into the system.
When the worker leans back, the system is activated (supporting
the worker’s body weight). Positioning devices limit free falls to two
feet or less.
F. Protection of Skylights and Access Hatches:
1. Existing skylights must be protected by grates or covers, and be
capable of supporting, without failure, at least twice the weight of
the workers, equip-ment, and materials that may be imposed on
the cover at any one time. 2. Roof hatch entrances need to be protected if too close to the roof
edge. They are considered holes when open (see section on Hole
Covers.)

4.1.1.13. PREPARATION
4.1.1.13.1. Surface Cleaning of Joints: Clean out joints immediately before installing
joint sealants to comply with recommendations of joint sealant manufacturer.
4.1.1.13.2. Thoroughly clean the areas that the new sealant will contact using a de-
greasing solvent such as toluene or xylene and the two-rag wipe technique. IPA
(isopropyl alcohol) is not a degreasing solvent. The new sealant should have a minimum contact area of 1/4”.
4.1.1.13.3. Remove all foreign material from joint substrates that could interfere with
adhesion of joint sealant, including dust, paints (except for permanent, protective
coatings tested and approved for sealant adhesion and compatibility by sealant
manufacturer), oil, grease, waterproofing, water repellents, water, surface dirt, and frost.
4.1.1.13.4. Clean porous joint substrate surfaces by oil-free brushing, grinding, blast
cleaning, mechanical abrading, or a combination of these methods to produce a
clean, sound substrate capable of developing optimum bond with joint sealants.
Do not damage finished surface of materials while performing cleaning operations. Remove loose particles remaining from above cleaning operations by vacuuming
or blowing out joints with oil-free compressed air.
4.1.1.13.5. Clean metal, glass, porcelain enamel, glazed surfaces of ceramic tile, and
other nonporous surfaces with chemical cleaners or other means that do not stain,
Rinconada Pool Bldgs Re-Roof Specification PF-00006 Section 07 92 00 Page 7
harm substrates, or leave residues capable of interfering with adhesion of joint
sealants.
4.1.1.13.6. Masking Tape: Use masking tape where required to prevent contact of
sealant with adjoining surfaces that otherwise would be permanently stained or damaged by such contact or by cleaning methods required to remove sealant
smears. Remove tape immediately after tooling without disturbing joint seal.
4.1.1.14. JOINT PRIMING
4.1.1.14.1. Prime joint substrates where indicated or where recommended by joint
sealant manufacturer based on pre-construction joint sealant-substrate tests or
prior experience. Apply primer to comply with joint sealant manufacturer's
recommendations.
4.1.1.14.2. Confine primers to areas of joint sealant bond; do not allow spillage or
migration onto adjoining surfaces.
4.1.1.14.3. Allow primer to dry. Do not prime areas that cannot be sealed the same day.
4.1.1.15. INSTALLATION OF SEALANT BACKINGS
4.1.1.15.1. Install joint fillers of type indicated to provide support of sealants during
application and at position required to produce the cross-sectional shapes and depths of installed sealants relative to joint widths that allow optimum sealant
movement capability.
4.1.1.15.2. Do not leave gaps between ends of joint fillers.
4.1.1.15.3. Do not stretch, twist, puncture, or tear joint fillers.
4.1.1.15.4. Remove absorbent joint fillers that have become wet prior to sealant application and replace with dry material.
4.1.1.15.5. Tolerances:
4.1.1.15.5.1. Minimum Sealant Contact Area: 1/4-inch.
4.1.1.15.5.2. Minimum Joint Depth: 1/4 + 1/8-inch, with the joint width at least twice the joint depth to allow the sealant its maximum
movement capability.
Rinconada Pool Bldgs Re-Roof Specification PF-00006 Section 07 92 00 Page 8
4.1.1.16. INSTALLATION OF JOINT SEALANTS
4.1.1.16.1. General: Comply with joint sealant manufacturer's printed installation
instructions applicable to products and applications indicated, except where more
stringent requirements apply.
4.1.1.16.2. Sealant Installation Standard: Comply with recommendations of ASTM
C1193 for use of joint sealants as applicable to materials, applications, and conditions indicated.
4.1.1.16.3. Installation of Sealants: Install sealants by proven techniques that result in
sealants directly contacting and fully wetting joint substrates, completely filling
recesses provided for each joint configuration, and providing uniform, cross-
sectional shapes and depths relative to joint widths that allow optimum sealant movement capability. Install sealants at the same time sealant backings are
installed.
4.1.1.16.4. Tooling of Non-sag Sealants: Immediately after sealant application and prior
to time skinning or curing begins, tool sealants to form smooth, uniform beads of
configuration indicated, to eliminate air pockets, and to ensure contact and adhesion of sealant with sides of joint. Remove excess sealants from surfaces
adjacent to joint. Do not use tooling agents that discolor sealants or adjacent
surfaces or are not approved by sealant manufacturer.
4.1.1.16.4.1. Remove excess sealant from surfaces adjacent to joints.
4.1.1.16.4.2. Use tooling agents that are approved in writing by
sealant manufacturer and that do not discolor sealants or
adjacent surfaces.

joint length for each type of elastomeric sealant and joint
substrate.
4.1.1.17.1.2. Test Method: Test joint sealants as appropriate for type of joint-sealant application indicated.
4.1.1.17.1.2.1. For joints with dissimilar substrates, verify
adhesion to each substrate separately; do this by extending
cut along one side, verifying adhesion to opposite side.
Repeat procedure for opposite side. 4.1.1.17.1.3. Inspect joints for complete fill, for absence of voids, and
for joint configuration complying with specified requirements.
Record results in a field-adhesion-test log.
4.1.1.17.1.4. Inspect tested joints and report on the following:
4.1.1.17.1.4.1. Whether sealants in joints connected to pulled-out portion failed to adhere to joint substrates or tore cohesively. Include data on pull distance used to test each
type of product and joint substrate. Compare these results
to determine if adhesion passes sealant manufacturer's
field-adhesion hand-pull test criteria. 4.1.1.17.1.4.2. Whether sealants filled joint cavities and are free of voids.
4.1.1.17.1.4.3. Whether sealant dimensions and configurations
comply with specified requirements.
4.1.1.17.1.5. Record test results in a field-adhesion-test log. Include dates when sealants were installed, names of persons who installed sealants, test dates, test locations, whether joints were
primed, adhesion results and percent elongations, sealant fill,
sealant configuration, and sealant dimensions.
