Exclusive service for architects and designers, investors, clients,
developers and contractors.

In reality,
changes on site due to
mistakes and lack of
information
lead to increase of costs,
delay and often they
compromise the quality
of the final product.
In the Construction Industry, the Tender process should ensure that
Time, Cost, and Quality in a project are in a perfect balance.

In reality,
just documents and
drawings are checked,
not the project itself.
Design mistakes will be
discovered just on site,
causing delay, extra-cost
and they will be cause for
litigation.
Design teams put in place processes to check mistakes and
inconsistency before issuing any document for tender.

In reality,
BIM is still seen as a tool of
visualisation, not as a
method to manage the
project.
BIM advantages and
potential are pretty much
unknown by the majority
of contractors, clients, and
investors.
BIM promises to avoid design mistakes by helping managing the
workflow and all the information since the earliest stages to completion.

However,
reality
can be different.
In theory, we should accept the reality that just on site we can sort out those
problems due to design mistakes due to lack of coordination.

HOW IT IS...
❖ Even if we check the drawings, the project
goes unchecked
❖ Design teams across AEC fields work in
silos until they face problems on site
❖ Every time, design mistakes and lack of
coordination pop up on-site
❖ Any time you spot a problem on site, it
start an endless process to sort it out
❖ Approving a change on site, especially
whether with cost-implication, is trying
and complicated
❖ Sorting a mistakes on site very often
requires additional work or re-working and
always it causes delays
❖ When there is a problem on site, the blame
game start and everybody is focus on
pointing fingers rather than finding a
solution
❖ Waste of time and money and profit loss
are a predictable outcome in the industry
...HOW IT COULD BE
★ We should check whether there are
inconsistency in the project not in the
drawings
★ We should find a moment to coordinate
the design across all the AEC fields before
going on site..
★ Buildability check should be a priority long
before going on site
★ Sorting mistakes in the office is hundred
times faster than on site
★ Sorting issue with a phone call and not
with endless meetings
★ Amend a drawing at the right time is
better than do re-working on site
★ Enhance collaboration helps problem-
solving attitude, blame game does not.
★ De-risking the project making the process
a win-win for everybody involved.

BIM in a nutshell.

Many people think that BIM is just the 3D model.
Actually the model is just the “M” that weights just 20% of BIM
where the “I” (Information) is much more important.
In other words, if you are using a 3D model for your projects, this is
certainly an advantage but you are missing 80% of the benefits of BIM.

The importance of “I” in BIM
For every single component it is possible to describe the Quality (from the simplest
description to full specification) and we know the Position from the model.
Quality and Position generate schedules (as finishes, fittings, doors and windows, etc).
From the model we extract the Quantity that, with price, give us the budget.

Exploiting the full potential of BIM, we have developed
BIM4T

BIM4T
Ten things to know:
1. It is a professional service, not a software
2. It helps on checking the project, it doesn’t replace design effort
3. It is applicable to every project, even those just drawn in 2D.
4. It works at any stage, but it is optimised for Tender
5. It gives the maximum accuracy of the Bill of Quantity
6. It guarantees the consistency among drawings, specs and BoQ
7. It is a reliable test of buildability
8. It helps in sharing information among designers and with client,
investors, and contractor
9. As service offer by a third party, it doesn’t require any special skill or
knowledge by the final user
10. It brings all the benefits of BIM in your projects immediately

BIM4T
How it works.
BIM4T
is the missing piece
that optimise the process
without making it too
complicated or difficult to
be managed.

BIM4T
It is based on an iterative process in 4 steps:
Check-in, Check-out, Estimate, Sign-off

At BIM Check-In we collect all the
information the design teams have
prepared for tender.
This is exactly the same package of
information that the Contractors will use
to make their offer and, if successful, to
build the project.
Nothing more, nothing less.
BIM4T

at Check-out we start the construction
process on screen(Construction
Modelling),
Including all its components and on the basis
of the information we’ve collected.
As we were in a real work site, we can:
● Check out all the information, their
completeness, clarity, consistency, and if they are
sufficient to complete the building process.
● Check out whether there are inconsistency in the
drawing which would mislead the builder.
● Check out inconsistencies among drawings,
specs and BoQ
● Check out clashing points (clash-detection)
among components (architectural, structural,
MEP)
If there is a problem, we tell the designers and they
can even use the model to figure a solution out.
They can do the changes, amend their documents
and put it forward for the second Check-out.
BIM4T

BIM4T
When the model is right, so it is the
project and it remains to check the
budget with Estimate
● Bill of Quantity saving
98% of time normally
required with traditional
methods
● Max accuracy in
measurement and no
computing mistakes
● Integration with standard
Price books, market
information, quotation
● Flexibility in organising
the information to
simplify cost analysis
Checking the budget at early stages, before
issuing for tender, gives the opportunity of
value engineering the project and optimise the
budget.

BIM4T
Check-in, Check-out,, Estimate, Sign-off
When both design and cost
are right, the project is
ready for Sign-off and
moves to the next stage.
Now it’s possible to proceed with
tender, or negotiate the price
with the Contractor, or start the
works if BIM4T is part of a Design
& Build contract.

BIM4T
Who & Why
1. Architects and Project Managers> Check and coordinated all
the design packages to avoid re-design during execution.
2. Interior Designers > integration and coordination of Interior
design with other AEC packages.
3. Private clients > Consistency among offers, transparency of costs,
clarity of contents.
4. Developers > Avoiding last minute changes, delays, increase of
cost, profit loss.
5. Investors > de-risking investment, reducing uncertainty of cost
and time, finance planning based on reliable information.
6. Contractors > check buildability of the project, completeness of
design information, avoiding litigation and waste of time.
7. All the stakeholders > upgrading to full project engineering,
standard and interactive package for construction, Smart Site
Management, Smart Building Servicing and Maintenance.

Construction
Modelling
allows to build the
building virtually on the
screen, including all the
components, solving
all the issues before
starting on site.
BIM4T
Why it works.

1
All the components, materials, fixture and fittings are
modelled: that way every detail is tested, all information
checked, and each components is counted in the estimate.
Three advantages of Construction Modelling

2
Checking buildability of the project, planning stage of works,
temporary measures, Health & Safety risks, managing overlapping works.

3
“clash detection” to find clashing points and to coordinate
components, service penetration planned in time to avoid re-work,
re-design, and delays.

Consistency and clarity.
The Construction Model
is a graphic
representation of the
project.
The Estimate Model
represents the project
analytically.
Both are always
synchronised.

Flexibility.
Quantity
information
Quality,
specs,
price
Cost
management
Maximum flexibility in
data management,
bespoke organisation of
information to simplify
cost analysis along with
client’s requirements and
complexity of the project.
Time
management

The Bill of quantity is
generated automatically
from the model with no
mistakes. Crossing this
data with agreed pricing
information, the
estimate can be obtained
in a matter of seconds.
Exactness and speed.

Talent wins games,
but teamwork and
intelligence win
championships.

Facts, statistic & Conclusions

FROM THIS...
❖ Along with Peter Caplehorn,
Construction Product Association,
“Currently we draw every project
2.5 times and construct it 1.5
times”
❖ Inaccuracy in the tender
package is accountable for a
difference up to + 50% from initial
contract cost and actual cost at
closure.
❖ Design mistakes and lack of
coordination are accountable for
40- 50% of increased cost.
❖ 25-30 % of increased cost are
consequence of initial mispricing
the project.
❖ Lack of clarity in the construction
package leads to clients changes
of mind during construction with +
20% cost on average.
… TO THAT
❖ The UK government expects cost
savings up to 20% thanks to BIM
and process optimisation.
❖ It has been reported a return on
investment of 10:1 by applying
Construction Modelling (CM).
❖ Where CM is applied just to MEP
component, analysis of case studies
has proved savings as much as
10.2 % in project time and 7.2 % in
project cost.
❖ If CM is applied to the whole
construction (not just MEP) time
and cost savings are likely to be
around 20%

STATISTIC
❖ 67% of professionals think that BIM is just for larger organisations and big
projects.
❖ The Office for National Statistics reported that in 2018 in the Construction
Industry there were around 295,000 (90.6%) Small firms (turnover up to 1M
turnover), around 30,000 (9%) Medium size firm (turnover from 1M to 30M)
and just 0.4% are Big firms (turnover over 30M)
❖ Just 69% of professionals use BIM (most of them are big firm over 51+
employees)
❖ Just 36% of small (up to 15 employees) and medium size firm (15-50
employees) use BIM
❖ 75% of BIM users use it just to create 3D models.
❖ Just 29% of BIM users coordinate the 3D model with Specs
❖ Just 15% of users use BIM on 100% of projects
❖ Just 46% use BIM across all stages
❖ In 72% of cases BIM is only used in the design stages (28% goes beyond)
❖ 67% of professionals think that BIM is just for larger organisations
❖ Just in 29% of cases BIM information are passed to who is responsible of the
management of the building
❖ 33% of works which have been developed with BIM are Residential
development.
❖ 90% of investors, developers, clients and designers are currently not
exploiting the potential of BIM because of the false belief that BIM is only
for big projects.

SINCE:
1. Implementing BIM and Construction Modelling can potentially bring savings
up to 20% of the Construction Cost
BUT:
1. professionals working with small/medium residential firm using BIM in all
their residential projects are just 1.8% of the total and just 0.5% of firms can
offer offer BIM integrated services as we do.
WE CAN STATE THAT:
1. There will be years before professionals and operators in the AEC
industry will be ready to fully implement BIM bringing benefits to all
projects.
HENCE:
1. BIM4T is a VERY unique package of service free from all the common
mistakes typically affecting the Tender package.
IN CONCLUSION
1. BIM4T, regardless the form of contract/tender, ensures that the project is
buildable, the information is complete and accurate, measurements are
rights, price are transparent and, eventually, the cost is fair.
2. BIM4T makes immediately available all the benefit of BIM for your projects
3. BIM4T allows saving money, avoiding waste of time, and preserving the
quality of all your projects.

Talent wins games,
but teamwork and
intelligence win
championships.
