Window Dressing
Glazing contractors help achieve
ROI throughout windows' lifecycles.
As is the case with many responsibilities
germane to facility professionals, windows can go largely
unnoticed unless a problem develops or a new application
is needed. Looking for help with glazing situations,
facility managers can turn to speciality contractors
who deal with such applications.
Whether building a new facility,
servicing an existing facility, or renovating an old
building, facility professionals will maximize their
window system's ROI by working with a professional glazing
team. This ROI can be achieved through architectural
aesthetics, applied performance, managed budget, and
on-time scheduling.
New Construction, Service,
And Renovation
Building and designing new
structures usually involves a construction team that
includes the facility manager, architect, and general
contractor. Because a window system is critical to the
exterior's desired design, it also is a good practice
to invite a glazing contractor to the table.
The earlier a glazing contractor
can participate in the planning process, the sooner
he or she can help the team move from generalized, paper
based manufacturers' specifications to a customized,
reality based solution. Working together with the designer
and facility manager, the glazing contractor determines
that the appropriate products are engineered to achieve
the owner and facility manager's specifications.
Throughout the lifecycle of
a facility, a glazing contractor can help preserve the
window systems' beneficial attributes. Regular maintenance,
building code updates, and emergency replacement are
a few of the services worthy of consideration.
Glazing contractors are the
key resource in helping to solve more persistent and
reoccurring window system issues such as air and water
leaks, rusting window frames, glass breakage, and fogging.
In collaboration with air quality testing and abatement
firms, they also can help alleviate mold, lead, and
asbestos associated with sick building syndrome.
For aging facilities in need
of more dramatic transformation, a glazing contractor
can work closely with the property management team to
update an outdated look and improve energy efficiency,
occupant health, and safety performance.
Working With A Glazier
A glazing professional recognizes
that every facility has its own special needs. Exemplifying
this professionalism, he or she should customize an
appropriate resolution to each building. One approach
is this recommended four-step process:
- Property Survey and Discussions.
The glazing contractor's renovation representatives
should meet with the facility manager to discuss the
problems and concerns of the window system. Completing
a cursory walk-through of the building, they usually
are unable to confirm suspicions at this early stage.
Typically, they will recommend proceeding to a hands-on
examination.
- Non Destructive Diagnostic
Evaluation. The glazing contractor assembles his or
her team and reviews the window system's area of concern
from both the interior and exterior surfaces. To pinpoint
root causes will require removing receptors, gaskets,
and glass to examine the exact condition of the system.
The review is non destructive in nature, and the openings
are returned to their existing condition. After completing
the evaluation, the team formulates resolutions to
the identified issues which are presented with budget
estimates to the facility manager. A joint decision
is made to pursue one of the recommended options.
At this point, a paper solution has been proposed,
but this still needs to be validated in the field.
- Field Application Of Proposed
Solution. A small-scale sample of the proposed glazing
solution is installed in the existing wall. This may
be as simple as replacing one window or as complex
as replacing a whole section of glass curtainwall.
In either scenario, the mock-up provides the opportunity
to see into the components of the original construction.
It also gives the facility manager the chance to view
the final product and consider any recommendations
or changes.This step further reduces liability for
both parties by allowing the glazing contractor team
to mitigate any hazardous materials, anchorage concerns,
or other discovery items that may have otherwise affected
future remediation work. Additionally, this small
scale installation enables the glazing contractor
to confirm the means and methods of construction prior
to beginning with the total project.
- Final Pricing and Remediation
Plan. Through the previous steps, the glazing contractor
isolates the area of concern, recommends options,
and validates a solution for the renovation. During
this final step, the contractor should establish an
accurate, cost effective price and propose a timeline
with start and completion dates based on mutually
agreed upon parameters.
An occupant disruption plan
should also be created to minimize the disruptions to
tenants and other personnel occupying the building.
The glazing team should understand this is a crucial
item. Once these items are agreed upon, the window system
renovation project can proceed.
A well chosen window system
can help save energy, lower maintenance costs, create
a comfortable environment, update aesthetics, and improve
security. Regardless of the reason, a glazing contractor
can help facility managers' achieve the ultimate goal-the
ROI that comes from these window systems.
