Fixed price contract, with management powers and flexible modification during construction, all built in |
First worked out in this form for West Dean Visitors Centre, UK, 1993, based on CES contracts used in California since 1983 |
In order to build a building by unfolding, the actual contract procedures themselves must be altered, to make the unfolding possible. Conventional AIA or RIBA contracts do not work, because the assumption they are based on, specifies that all details are fixed from the start, and the performance of contract is based on the strict adherence to what is in the drawings. Any time a sensible modification has to be made, while the building is being built, the client has to pay extra for a "change order" and is at the contractor's mercy for whatever price he chooses to charge. The CES contracts are specially designed to permit unfolding to occur. They are types of management contract. No profit is allowed, and instead the manager is paid a fixed fee of 20% to run all the subs and oversee construction operations. The project manager's responsibilities also include making constant visits to the building, as it unfolds, identifying configurational adjustments that will improve the building. | |
MANAGEMENT AGREEMENT FOR THE CONSTRUCTION
OF ___________
This
agreement is made on this day of
___________, between The Trustees of the ___________ Foundation (hereinafter
called Employer), and the Center for Environmental Structure (hereinafter
called CES) acting as Management Contractor and General Contractor of record,
for the purpose of building the ___________ at ___________ (hereafter called
Project), according to the plans and Sub-Contract arrangements prepared by the
Center for Environmental Structure.
This
Agreement is incomplete at the time of signing and is therefore subject to the
overriding conditions given at Appendix 3 - Start-Up Arrangements.
ARTICLE
1. DEFINITION OF PROJECT
The
work is shown on the drawings that are attached to this agreement at Appendix
1, and specified in the cost plan of proposed Sub-Contract construction
operations attached to this agreement at Appendix 2.
The
following aspects of the work will be built as specified in the drawings:
a. Siting
of the building as shown on the site plan - Drawing No AL-1-F---
b. Configurations
and dimensions of the building and rooms as shown on the floor plan - Drawing
No AL-2-F---
It
is understood that drawings depicting the Project have been prepared for
statutory planning and building regulation approval purposes, and are not to be
construed as binding architectural plans and specifications. Construction details will change as
Sub-Contracts are settled.
The
intent of this agreement is to build the building according to the volumetric
envelope given in planning permission documents, and with the visitor flow and
room layout defined in documents referred to in this Article. These features shall be considered as the
major aspects of the design, and all other features of the building shall be
held as lesser aspects of the design.
ARTICLE 2. BASE PRICE
FOR PROJECT
The base price of the
Project will be subject to Sub-Contract base prices, contingency and management
fees. The total price of the project including these items is £___________ plus any
change orders.
The cost plan proposals
attached at Appendix 2 define the relative specification of work under each
Sub-Contract heading, and base price for each.
Based on these documents, and the major Sub-Contract proposals given at
the Addendum to Appendix 2, the base price of the Project (excl VAT) will be
£___________, together with the price for any changes agreed to by the Employer in
writing.
It is agreed that while
detailed specifications of work in different categories may change during
construction, the cost plan is understood as a baseline for all
specifications. This means that the sum
allocated to any specific item is to be interpreted as a specification which
provides that what is built may be expected to be of that standard which can
reasonably be built, at prevailing market rates for the sum specified, at the
time of construction.
ARTICLE 3. CES AND
EMPLOYER RESPONSIBILITY
The general intention of
this agreement is to create conditions where the major aspects of the design
remain fixed (except when modified through mutual agreement by both Employer
and CES), while giving CES full scope to develop the lesser aspects of the
design, within the prescribed budget, in such a way as to maximise the harmony
and feeling of the whole, in relation to use and appearance.
CES shall provide
management services and supervision necessary to execute and complete
construction of the Project.
CES as Management
Contractor will;
1. Enter
into binding Sub Contracts with Sub-Contractors,
2. Organise
and manage the Sub-Contractors,
3. Make
changes to the lesser aspects of the design in accord with the general intent noted above,
4. Determine
how to spend the budget allowances within the agreed base price of the Project,
5. Administer
construction and interpret such work in relation to applicable codes of
practice and statutory requirements.
6. Inspect
finished work,
7. Keep
full and detailed financial accounts as may be necessary for the construction of the Project on
behalf of the Employer, reporting
monthly to the employer and making records available to the Employer at
any time.
The Employer will in all
matters of Sub-Contractor dealings, in all matters of lesser design changes,
and in all matters of money management within the base price of the Project,
grant to CES complete authority to exercise its judgement on behalf of the Employer.
ARTICLE 4. CES GENERAL
PHILOSOPHY
It is believed that the
approach to construction laid out in this agreement and based on the
fundamental responsibilities above will secure for the Employer the highest
quality Project possible for the agreed base price.
Specifically, this
approach is designed to eliminate the profit motive of the general contractor
which takes value, meaning and quality away from the building. By setting a fee for the management of the
Project and maintaining open records of all transactions, the typical
overbidding by the contractor to protect against unforeseen overruns, risks and
provide markups on materials and subcontracted work are eliminated. In more typical Contractor-Employer
arrangements any unused overbid money becomes windfall and additional profit
for the contractor and does not benefit the building or the Employer. In the model laid out in this contract all
available money is spent for the betterment of the building.
This method also
provides the framework for efficiently dealing with changes which are a crucial
and fundamental part of making a good building. In typical Employer-Contractor conditions of contract changes
lead to an exorbitant surcharge disproportionate to the direct costs of the
changes in addition, and prolongation and disruption costs all of which
effectively provides the contractor a windfall profit. Even changes which reduce costs are
typically charged as extras. In the
method laid out here, design changes are not subject to additional surcharges
and are charged at their actual costs within the agreed base price for the
Project, except for Employer additions as Article 6.
CES encourages the
Employer to review all Sub-Contracts, and to propose alternative lower priced
subcontractors. CES will evaluate the
Sub-Contractor proposals and award Sub-Contracts if CES determines that it is in
the best interest of the project, and provided that these proposals are
consistent with the construction schedule.
ARTICLE 5. DESIGN
DECISIONS AND CHANGES INITIATED BY CES
A further and essential
part of the CES philosophy is that there are no precisely defined plans and
specifications and that construction is a continuum of design. CES has the responsibility to interpret the
emerging building and will have authority to make decisions and changes that impact on lesser aspects of design as it
determines necessary, without written confirmation
from the Employer, as
long as these decisions do not increase the base price of the Project or affect
major aspects of design.
Notwithstanding this, whenever possible CES will confer with the
Employer, but CES is held in trust with
the building and is not obliged to do so on lesser aspects of design. Design
decisions and changes may arise for a number of reasons. CES-initiated design changes may be
generated in response to the emerging building, for example as the building and
rooms begin to take shape, doorway sizes and locations, window sizes and
locations, wall locations and wall lengths, cabinets, finishes, may have to be
altered. These decisions can only be
made on site, during construction, as the building is taking shape.
CES-initiated design
changes will also be required to contain costs within the agreed base price for
the Project. For example as a result of
some unforeseeable problem, or as a result of a potential increase in price due
to a previous design change, it will become necessary to make changes in the
building to offset the increase. This
is not something that might
happen, it is something that will
happen. Although often seen as
negative, these types of changes are more often than not positive changes which
ultimately result in producing the best building.
CES will confer with the
Employer in those design decisions which the Employer has identified as
important ahead of time, and before making any major design changes,
Nevertheless, in lesser matters, CES has the main commitment and responsibility
to "listen" to the emerging building, and to do what is in the best
interests of the building.
ARTICLE 6. CHANGES NOT COVERED BY ARTICLE 5.
Changes not covered by
article 5, and which will result in an increase of the agreed base price will
be approved in writing by the Employer.
In cases where an increase of price is anticipated, the Employer must
approve the change in writing before CES can begin the work. If the Employer does not approve the change,
the work will not be done.
The cost plan also
includes a supplement containing certain optional extras, which the Employer
may or may not elect to include in the project. If the Employer does choose to include any of these optional
items, he must so signify by initialling the chosen items in the cost plan
supplement. Decisions about optional
extras may be made during construction provided they are consistent with the
construction schedule.
ARTICLE 7. CES SPECIAL
CONSTRUCTION METHODS AND PHILOSOPHY.
The Employer recognises
that the methods and philosophy of CES include unusual use of materials, and
unusual combinations of high and low levels of quality and finish. The building will not necessarily be
designed to the usual industry standards for residential or public buildings,
and the Employer's desire to break with these prevailing standards is
explicitly part of the intent of this agreement; except in so far that the
building design does not conflict with normally accepted statutory regulations
and requirements.
The Employer approves
the form and content of the CES Sub-Contract forms attached to this agreement
as an addendum to Appendix 2, and recognises the right of CES to make
substitutions as provided in the Sub-Contract agreements. The Employer expects
specifically for CES to exercise independent judgement in carrying out the
above-described construction methods and philosophy.
ARTICLE 8. SUMMARY OF CONSTRUCTION OPERATIONS
The construction will be
organized under the following broad
Sub-Contract operations, with the following sums allocated to them. A detailed breakdown, showing the base price
of the elements in each operation, 15% contingency, and CES management fee is
given at Appendix 2.

TOTAL COST OF PROJECT
£ __________
The total sum of money assigned
as base price plus extras, and the total sum of money under contingency will be
used by CES to build the Project. The
use of this money is under the sole discretion of CES acting as manager for the
Employer, and may be directed to offset a base price increase, or for any items
required by CES to improve the Project.
ARTICLE 9. CONTINGENCY
To protect the Employer
and the Project against unforeseeable fluctuations of price, unforeseen site
conditions, and other changes, each of the budgeted amounts in article 8
contains a contingency of 15%. The
contingency money is to be used entirely at CES discretion, for the benefit of
the Project as judged by CES. CES shall
have the right to distribute and redistribute this contingency money as it sees
fit, in order to meet difficulties and changes which arise in the Project, and
whenever possible, to make improvements and extras which CES believes will
increase the harmony of the emerging building.
CES's intention is to
maintain as much of the 15% contingency money as possible, and use this money
to pay craftsmen who will make various finishing touches throughout the
Project.
ARTICLE 10. MANAGEMENT FEE
The Management Fee will
be paid directly to CES as outlined under Article 12. The management fee will be used by CES to manage the project and
will pay for CES management labour and overheads.
The total management fee
due to CES is £ ________ which represents
20% of the total base price and contingency allowance of construction. This sum, together with any additional
management fee due under Article 6 will be paid to CES according to the
arrangement described in Article 12.
ARTICLE 11. PAYMENT PROCEDURE
CES will open a
dedicated Project chequing bank account at its own bank in the name of the
Employer who shall make deposits to the account according to the schedule
below. CES will be a sole signatory on
this account, and will hold the Project cheque book. The type of Project chequing account shall be agreed by CES and
specified by the Employer.
The basis for payment
will be the list of construction operations;
summarised in Article 8 and detailed at Appendix 2. The Employer will
make deposits to the Project chequing account according to the following schedule
for each operation - which shall include contingency, management fees, Article
6 additions and Employer allowances.
50% of the price of the
operation will be deposited to the account upon notification of the
commencement of that operation, either on or off site.
35% of the price of the
operation, on demand, when a reasonable portion of the work is completed.
10% of the price of the
operation when notified by CES that the operation is at least 85% complete.
The remaining 5% on
substantial completion as Article 15. (or on earlier agreed substantial
completion by a Sub Contractor).
As each cheque is
deposited to the account, CES will withdraw the appropriate amount from the
management category (as shown at Appendix 2) to make payment for construction
management fees, and regulate interim payments to Sub-Contractors based on
progress.
All records from the
project account and all invoices for materials and labour, and all
subcontractor's billings will be available for the Employer's review. CES will provide to the Employer monthly
financial statements showing Project chequing account credits and debits;
Project expenditure against progress and expenditure commitment and forecasts.
ARTICLE 12. SUBCONTRACTORS
Sub-Contract proposals
will be attached as an addendum to Appendix 2.
These proposals, signed by the various subcontractor's are a part of this Management Agreement, and
serve as the basis for the project specifications and the base price for the
Project. At the appropriate time CES
will obtain Sub-Contract proposals from Sub-Contractors for remaining items. In
performance of this task, CES will seek out and hire subcontractors which in
CES's opinion are most appropriate for the particular element of
construction. The criteria may be price
in one instance, timeliness in another, and quality of work in another. CES is under no obligation to find the
"lowest" priced Sub-Contractor, nor the "best"
Sub-Contractor.
Should a subcontractor
default on their Sub-Contract, for any reason, this shall be dealt with
equitably between Employer and CES. CES will endeavour to re-negotiate or find
another Sub-Contractor to perform the work. CES will act in the best interests
of the Employer and the Project with respect to time, quality, flexibility, and
price, but CES cannot guarantee to provide replacement Sub-Contracts or
Sub-Contractors at the same price.
The relationship between
CES and the Sub-Contractors shall be a Contractor-Sub-Contractor
relationship. Within the confines of
such a relationship, CES will include its best efforts to provide appropriate
guidance of the subcontractors in the performance of their work. CES is the sole agent on behalf of the
Employer. The Employer, or any agents
of the Employer aside from CES, are explicitly forbidden from giving any
directions to, or making any requests directly to any of the
subcontractors. The Employer may of
course make requests through CES as provided in Article 6.
ARTICLE 13. TIME
The work to be performed
under this agreement shall commence within 28 days of the signing of this
contract. The work shall be completed
in accordance with a construction programme subject to:
Both
the Employer and CES desire to complete the project in 9 months starting from
the date of commencement.
CES
will provide the Employer with an estimated construction schedule for the
project. This schedule shall indicate
the dates for the starting and completion of the various stages of the
construction and shall contain the necessary information to allow the Employer
to monitor the progress of the work. It
shall be revised as required by the conditions of the work and those conditions
and events which are beyond the control of CES.
The
Employer agrees that if the building process is slowed down, by any act or
neglect of the Employer, by any separate contractor employed by the Employer,
by any unreasonably slow process of decision making or design negotiation from
the Employer, CES will then be entitled to an appropriate increase of
management fee, to make up for the extra time.
If
the building process is slowed down for any reason not caused by CES
negligence, CES and the Employer will negotiate fair compensation if any
additional management fee is required.
Adherence to time
conditions is of vital importance to the proper running of the Project on site,
and is of material importance to the successful completion of this
agreement. It is implicit therefore
that CES will make its best endeavours to complete the Project to programme and
will not seek additional management fee for extra time due to a CES default.
Time control of the Project shall be exercised by CES through the regulation
and deferment of interim payments to Sub-Contractors.
ARTICLE 14. SUBSTANTIAL COMPLETION
The date of substantial
completion of the project or a designated portion thereof is the date when
construction is sufficiently complete in accordance with the drawings and
specifications so the Employer can occupy or utilize or, in fact, does occupy
or utilize, the project or designated portion thereof for the use for which it
is intended.
The date of substantial
completion shall be established in writing, signed by the Employer and
CES. At that time a list of defect and
deficiency items to be completed or corrected (if any) shall be prepared by the
Employer and CES along with a time schedule for their completion or correction,
and any remaining unpaid balance of the contract, including the 5% Sub-Contract
and management fee retentions will be deposited by the Employer to the Project
cheque account.
ARTICLE 15. FINAL COMPLETION AND FINAL PAYMENT
Following full
completion of the work as defined by the defect and deficiency list (Article
15), final inspection and acceptance of
the work in writing by the Employer, CES shall have authority to make final
payments to Sub-Contractors, and to withdraw final payment of the management
fee. To protect the Employer CES agrees
that they will not use these funds to make final payments until the
subcontractor has satisfactorily completed all work and rectified defects. When all payments have been made, CES will
issue a final completion certificate to the Sub-Contractors.
ARTICLE 16. CES OBLIGATION AND MAINTENANCE PERIOD
CES will maintain 5% of
the total of all contingency sums, in the Project account, for a period of 6
months after substantial completion.
The money will be spent for repairs and maintenance items which occur
after substantial completion and are not provided for through the defect and
deficiency list and retentions held on Sub-Contractors. CES will use the money to fix items that are
unsatisfactory to the Employer.
If 6 months after
substantial completion, this money or any part of it remains unspent, CES will
use the balance in consultation with the Employer, to make some nice small
improvements to the buildings. CES shall
have no further obligation, beyond that covered by this money, for making
repairs or improvements on items considered unsatisfactory by the Employer but CES will make its best efforts to help
the Employer enforce the warranties provided by Sub-Contractors.
ARTICLE 17. UNKNOWN CONDITIONS
The Project includes
modification or connection to existing structures and below ground construction
where it is not possible to anticipate all problems which may arise with such
work. If conditions are encountered on site which vary from
those indicated by the agreement documents, and are such that the performance
of work is affected, the base price of Project and schedule shall be equitably adjusted in writing between CES
and the Employer upon claim made by CES.
ARTICLE 18. INSURANCE
CES will maintain the
following insurance to cover CES's operations under this agreement:
1. Employer's Liability insurance for any
employees CES engages directly, together with Public Liability insurance in the
sum of £1,000,000 for those associated with CES's management team.
2. CES will, in addition, request that all
Sub-Contractors provide Employer's
insurances as appropriate and Public
Liability insurance in the sum of £1,000,000.
The Employer shall take
out and maintain a Joint Names Policy for All Risks insurance of the project
during construction to cover all risks of physical loss or damage.
ARTICLE 19. HEALTH AND SAFETY
CES shall take necessary
precautions for the safety of CES employees on the job, and shall comply with
applicable provisions of Health and Safety legislation. CES shall have no responsibility for the
abatement of safety hazards resulting from work at the job site carried on by
other persons, or by subcontractors.
Sub-Contractors will be responsible for their own safety, but CES and
CES employees will encourage safety on the site.
ARTICLE 20. WARRANTIES
Warranties and
guarantees obtained by CES from any manufacturer, shall be deemed to have been
obtained for the benefit of Employer.
CES will collect all equipment manuals and deliver them to the Employer
together with all written warranties from equipment manufacturers, and CES will
have no further obligation with respect to them.
ARTICLE 21. ATTACHMENTS
The subcontracts and documents hereto at
Appendices 1 and 2 are expressly
incorporated into this agreement To the
extent the attachments are inconsistent with this Management Agreement, the
terms of the Management Agreement shall govern.
ARTICLE 22. ARBITRATION
Claims, disputes and other
matters in question between the parties to this agreement arising out of or
relating to the agreement, and which cannot be resolved between the parties,
shall be decided by arbitration in accordance with the construction industry
arbitration rules prescribed by the Chartered Institute of Arbitrators, unless
the parties agree otherwise. This
provision shall be specifically enforceable in any court of competent
jurisdiction.
Notice of demand for
arbitration shall be filed in writing with the other party to this agreement
and with the Chartered Institute of Arbitrators. The demand shall be made within a reasonable time after the
claim, dispute or other matter in question has arisen. In no event shall the demand for arbitration
be made after the date when the applicable statue of limitations would bar
institution of a legal or equitable proceeding based on such claim, dispute or
other matter in question.
The award rendered by
arbitrators shall be final, and judgement may be entered upon it in accordance with
applicable law in any court having jurisdiction.
Unless otherwise agreed
in writing, CES shall carry on the work and maintain its progress during any
arbitration proceedings, and the Employer shall continue to make payments to
CES in accordance with the agreement documents. This article shall survive
completion or termination of this agreement.
ARTICLE 23. LEGAL FEES
In the event that either
party files suit to enforce the provisions of this agreement, the prevailing
party shall be entitled to reasonable legal fees as cost of suit, to be fixed
by the Court.
ARTICLE 24. MANAGEMENT EXPENSES
The Employer undertakes
to make available and to place where most convenient an existing sectional
shed, hooked to electricity and telephone with use of the existing toilet in
the gardens area, and to provide simple fencing to delineate the building site
from the public way on the Estate grounds.
Telephone, fax, electronic transmissions, copying
and mailing expenses will not duplicate those agreed inthe first contract for the
entire process of design and construction and shall be reimbursed at cost
directly to CES.
