TOP 10 WAYS TO KEEP YOUR PROJECT ON TIME AND ON BUDGET
There are many factors that can affect the success of a project. Following are 10 of the most common issues experienced during insulation installation and solutions to ensure they don’t negatively affect the project. These issues tend to crop up repeatedly, so it is important to continually reinforce these lessons to project teams. By avoiding these issues, you can help ensure your project meets the planned deadline and budget.
1.
Problem: Scheduling and Sequencing of Work
One common issue is the lack of a
schedule or the use of a schedule with inadequate time allocated for insulation
activities. It is fairly common to have partial releases on a site when part,
but not all, of a section is completed. This can hinder the efficiency of work,
as well as causing multiple trades to be working in an area at one time—leading
to slower work schedules or the need for repeated visits to a part of the project.
Staying on time is also critical—work that is released late can cause increased
costs because workers might not be able to access the area they need without
working over or through other trades.
Solution
These issues are mostly avoidable if
those managing the project are aware and take appropriate action. Solving these
problems with the general contractor or mechanical contractor as or before they
occur, rather than waiting, can ensure the overall project stays on budget and
is successful. Proactive communication prior to the start of project is a must.
Additionally, it is advisable to hold weekly project status meetings to discuss
any issues and to communicate the current state of the project. If there are
delays, it is incumbent on the insulation contractor to provide notice on cost
impacts as soon as possible or per contractual requirements.
2.
Problem: Access
Failing to include a clearly defined
access plan and the associated costs in the bid has a huge potential financial
impact. Many times scaffolding, man lifts, and other forms of access to work
areas are underestimated or not clearly enumerated in the request for proposal
(RFP) or a contractor’s proposal. Once again, cost overruns due to
underestimated scaffolding or lift costs as well as loss of productivity are
likely to occur when there is not an agreed-upon access plan with the client
and the associated costs are not contained in the proposal.
Solution
During the bidding process, make sure
the insulation contractor qualifies and clarifies access plan requirements and
costs. This must be agreed upon and part of the contract document. Prior to
mobilization, it is helpful to meet with the insulation contractor to review
the access plan requirements. It should also be revisited during weekly project
status meetings.
3.
Problem: Damage to Installed Insulation Systems during Construction
Insulation being walked on and damaged
by other trades during construction is a constant
problem on projects. This may lead to conflict on the site if there are disagreements about who caused and is responsible for the damage. It can sometimes fall to the insulation contractor to correct all damage to the system during construction. This frequently results in a contentious and costly issue, often near the end of the project.

It can sometimes fall to the insulation contractor to correct all damage to the system during construction. This frequently results in a contentious and costly issue, often near the end of the project.
Solution
Damage to insulation systems is likely
to occur on any jobsite. The issue can be mitigated, however, with proactive
and constant communication between the trades. It is advisable to bring up the
issue at weekly meetings and ensure there is an awareness down though the field
level. For the insulation contractor, it can be useful to create a
damage-to-work document complete with pictures and a description of the damage.
This document should be updated weekly (must be a cumulative, living document)
and transmitted to the general contractor or mechanical contractor each week,
with cost estimates to repair the damaged items. Damaged insulation compromises
the integrity of the system, and even opens up the potential for system
failures. Being proactive about preventing damage to the insulation will save
the building owner money down the road.
4.
Problem: Material Storage
Onsite material storage that is not in
close proximity to the work area can be costly. Many times, cost overruns for
material handling and loss of productivity occur because these costs aren’t
accounted for at bid time or there isn’t a good project logistics plan in place
from the start. Remember, if the installers don’t have the materials, they can’t
put them on, potentially leading to project delays. Another potential issue is
weather—if the materials aren’t stored in a protected area, they can be at risk
of damage from rain or high winds if they aren’t secured. If the insulation
becomes wet, it may need to be reordered incurring additional costs and delays.
Solution
Make sure you receive detailed material
storage and laydown requirements for the project in the contractor’s proposal.
Laydown requirements refer to a specified place where material will be stored.
This must be agreed upon and be part of the contract documents. Costs for this
function must also be included in the contractor’s estimate. It is important to
ensure this is clear prior to mobilization, and to abide by the terms and
conditions contained in the contract.
5.
Problem: Interferences
Many times there is a lack of adequate
room to install the specified insulation thickness. This can be caused by a
design that doesn’t leave enough room for the required insulation thickness or
other trades installing parts of the job out of sequence, lessening the
available area for insulation. Unfortunately, sometimes the insulation’s
thickness is modified to fit the available space. It is never recommended to
allow this, as it could cause performance issues with the specified insulation
system down the road. Modifying the system without engineering approval could
lead to costly rework requirements. Additionally, the field modifications
increase the cost of installation by slowing productivity down on the initial
installation. Finally, a system without adequate insulation thickness may not
run as efficiently, leading to higher operating costs down the road. Other
interferences include physical barriers such as temporary hangers. The
insulation contractor will have to work around the temporary hanger and leave
space for where the permanent hangers will go, which will necessitate multiple
run-throughs and can increase project costs.
Solution
The first step in preventing this issue
is for the mechanical engineer to know the pipe size and design enough room for
the appropriate amount of insulation. It is particularly important to design
enough space for valves to be insulated—this tends to get overlooked and can
lead to system failure if the valves do not have sufficient insulation.
Staggering the valves can be one option, as it can be hard to fit the proper
insulation around valves if they are in close proximity. At bid time or prior
to the start of the project, it is advisable to meet with the mechanical contractor
to discuss space requirements needed for the total finished specified
insulation system. This should be followed up with a written document detailing
the meeting. The insulation contractor should notify the owner and general
contractor that the lack of appropriate space requirements may result in an
insulation system that cannot be warranted. Insulation systems should not be
modified from required thicknesses due to lack of appropriate space
requirements. This may result in insulation system failure as well as costs
impacts to the client. Solving these issues upfront will save time and money.
In terms of other interferences, such as temporary hangers, proactive
communication between the trades responsible for these systems can help them
establish a schedule to minimize repeated trips and keep costs under control.
These types of issues should be discussed in initial planning meetings and
revisited in weekly meetings.
6.
Problem: Lack of Proper Workflow (Jumping Around)
Incomplete releases of work are common
and always quite costly to the insulation contractor and ultimately to the
owner. They often cause multiple trades to be working in one area at the same
time, and also necessitates multiple run-throughs by different trades on site,
which can cause work to go more slowly. Normally, they are a result of a lack
of good scheduling or when a client—who could be the mechanical contractor,
general contractor, or owner, depending on the project and who the insulation
contractor is working for—gets behind and must rush to get back on schedule.
This can be disruptive to overall progress and lead to stalls in progress,
causing potential delays to the overall schedule.
Solution
During the proposal process, discuss
and clarify what is expected regarding minimum expected work backlog
(percentage of effective work available) for the insulation contractor prior to
mobilization. The general contractor, building owner, or mechanical/
plumbing contractor should sit down with the insulation contractor and come up with a schedule to minimize delays caused by improper workflow. It can be helpful for the insulation contractor to provide weekly reports to the client as to the percentage of available work released ahead, as well as completed, by the contractor. Cost impacts due to jumping around should be given as soon as possible or in conjunction with contract requirements.

7.
Problem: Leaving Welds-Fittings-Hanger Points Open
Many times specifications or contract
documents call for welds and fittings to be left open for testing and
inspection purposes. This requires the insulation contractor to work multiple
times in an area to complete the insulation system. This will increase the cost
of installation and can also cause delays.
Solution
During the bid process, get pricing
from the contractor on the impact that multiple run-through will cost to get
an idea of the potential impact from this issue. It is good practice to meet
before the project to attempt to reduce or eliminate having to go back and fill
in welds or fittings. As always, proactive communication and collaborative
planning are key to avoiding issues that cause increases in budget or project
delays. Minimizing the need to go back and re-insulate can decrease costs and
save money for the building owner or manager.
8.
Problem: Sub-Tier Insulation Contractor Status
Many times there is no direct
communication link with the prime contractor and other trades by the insulation
contractor. This typically results in work being done out of sequence and can
potentially have a costly impact for the insulation contractor. It is most
prevalent on commercial work and sometimes occurs in the industrial environment
as well.
Solution
Recognize and be pro-active on
communication and payment issues. Make sure to include the insulation contractor
in weekly subcontractor site meetings and be prepared to discuss relevant
issues at the meeting. Document the discussion in written format so everyone is
on the same page—communication and documentation are vital to preventing
slowdowns and additional costs.
9.
Problem: Hot Spots/Cold Spots
We have all encountered warranty issues
that more than likely could have been avoided at the time of initial
installation. These issues can potentially be costly and lead to headaches for
the building owner or manager. Hot or cold spots almost always result from
workmanship issues—insufficient insulation on fittings, gaps in insulation,
etc. In a cryogenic system, improper insulation can lead to freezing and system
failure, which can lead to huge repair costs for the building manager or owner.
Solution
Continuous quality control (QC) and
quality assurance (QA) are the keys to preventing hot and cold spots in a
system. A high-quality contractor should provide specific craft training on the
installation details of the specified insulation system prior to each person
beginning work on the project. Additionally, QC/QA inspections should be done
daily to ensure compliance with project-specified and industry-standard
installation requirements. In this instance, hiring matters. Make sure you
enlist the services of an insulation contractor that is proactive about these
issues and has a QC/QA process in place for the project.
10.
Problem: Poorly Installed Insulation
Generally speaking, if an insulation
system visually does not look good, it probably won’t work well. Gaps,
insulation that isn’t securely fitted to the pipe, or other installation issues
can lead to severe performance issues down the road. As with other issues,
improperly installed insulation puts the system at risk of inefficiencies or in
the worst case, failure.
Solution
Again, this will come down to hiring a
quality insulation contractor. During the bid process, inquire whether the
contractor provides specific craft training on the installation details of the specified
insulation jacketing system. Additionally, make sure they will perform QC/QA
inspections daily to ensure compliance with project specified and industry
standard installation requirements.
