of the National Committees on them
The Ministry of Forest and Water Management of the Slovak socialist Republic establishes, according to the Article 41 paragraph 1 c) of the Act No. 138/1973 Coll. on the Water (the Water Act), and according to the Article 10 paragraph 5 of the Act of the Slovak National Council No. 135/1974 Coll. on State Administration in the Water Management:
Article 1
This Regulation regulates professional technical-security supervision on the barrages, dams, dikes, as well as on parts of the buildings, determined for modification of water flows, for the protection against flooding, for shipping purposes, for water withdrawals, for discharging the waste water, and for the other usage of the water, as well as on created ponds (hereafter „works“) the administrators (owners, users, respectively investors) of these works, are obliged to arrange, and also the technical-security supervision, which, at the works, is being realised by the national committees.
PART ONE
Volume One
Professional technical-security supervision
Article 2
(1) Professional technical-security supervision (hereafter „supervision“) is professional activity for exploring technical statement of the work, from its security and stability point of view, and possible reasons of the breakdowns, and for proposing the measures for improvement.
(2) The supervision is being arranged in the period of preparation of the work, and is being realised during the construction, or reconstruction, during whole period of operation of the work, until closing the work for harmless statement.
(3) Investor fulfils the obligations, imposed for the administrator, according to this Regulation, during the preparation and construction of the work.
Volume Two
Categories of the works
Article 3
(1) For the aims of the supervision, the works are being categorised into I. to IV. category. The category of the work is being determined by the Ministry of Forest and Water Management of the Slovak socialist Republic (hereafter „the Ministry“), after negotiating with relevant regional national committee.
(2) When it is the work, with the exemption of the works, which were under construction or operation, as for the 1st of January, 1974, the administrator is obliged, no later than before finishing the project task of the construction, or reconstruction, respectively within 6 months from the day of the force of this Regulation, to submit to the Ministry the proposal for determining the category of the work.

(3) After the reconstruction, or modification in the usage of the work, and for the works of the III. and IV. categories, as well as when the construction at the area, endangered by the work, is being changed, the administrator is obliged to propose examination of determined category of the work, to the Ministry.
Volume III
Principles of performing the supervision
Article 4
In the frame of supervision, according to the kind and type of the work, adequately to the category and to technical statement, mainly changes and appearance of following facts and realities are being monitored:
a) static and dynamic stability of the work, respectively its parts,
b) space changes of the work, as a complex against its surroundings,
c) work deformation, mutual shifting of individual parts of the
constructions, splits in construction material,
d) deformation of sub-base,
e) physical-mechanical characteristics of construction and sub-base
materials,
f) regime of ground and soaking water, i.e. the pressure of the
water, connections of the soakings, the direction and the speed of the
water flow, partial and total quantity of the soakings, water jetting in
the area of the work,
g) the functions of protecting, sealing, filtration and drainage elements
of the work and of its sub-base,
h) hydraulic fall in construction and sub-base materials and their
filtration stability,
ch)the influence of the surroundings to technical statement of the work,
and of its technological equipment, i.e. weather influences (mainly
freeze, and wave-beating), slumping of the banks of the pond and
slumping in close area of the work, aggressive influences of the air and
water in the pond, ground and soaking water, the influences of
construction and tearing jobs around the work, earthquakes, undermining,
influences of operational and transport quakes, the influences of
vegetation and animals, and non-approved actions of the third persons,
i) the influence of the operation to technical statement of the work and to
its technological equipment, i.e. the influences of the manipulation
with water in the pond, mechanical and other influences of discharged
water and by the water floated materials, out-usage and possible
influences of breaking the locks and dike constructions of the spouts,
overfalls and withdrawing equipment,
j) flow relations in compare to original assumptions of the proposal for
discharging and overfall equipment, e.g. influencing the flows at upper
flow by new works, by breaking or by cancelling the existing works, by
change of outflow relations in the waterhed, by ice barriers, by
vegetation,
k) other facts and realities, which may, according to local circumstances,
influence the security of the work.
Article 5
(1) Supervision is being realised mainly by viewing the work, measuring its deformations, soakings, and elaborating, analysis and evaluating the results of all examinations and measuring, in the relation to predetermined marginal 1) or critical values, 2) assumptions of the project, knowledge from the construction, and from previous operation of the work.
(2) Reasonably divided monitoring of the realities, including common measuring of the values and statements, which are significant for the security of the work, also by-passing around, reports and inspections are the basis for realising the supervision.
(3) The selection of possible reasons of the breakdowns and other facts and realities, which are being monitored by the supervision, the selection of the measures and methods of monitoring and measuring, the quantity of installed equipment, the extent and quantity of working actions must be proportional to the category of the work, statement and operation of the work, respectively to local conditions, and must be in accordance with valid technical norms and current statement of engineer knowledge and possibilities of realisation.
---------------------------------------------------------------------------
1) Marginal value is the expected limit value of the fact or reality for
chosen statement of loading.
2) Critical value is the value of monitored fact or reality, of which
appearance inspires the awareness for the security of the work, and
during which, the emergency measures are being therefor prescribed.
Article 6
(1) For the works of I. and II. categories, the administrator is obliged to arrange realisation of the supervision through authorised organisation, to which, he is obliged to submit the basis, according to the Article 5 paragraph 2, in the extent, determined by the program of the supervision.
(2) For the works of III. and IV. categories, the administrator realise the supervision by himself.
(3) The supervision is being realised proportionally to the category of the work, but at least in the extent, determined by this Regulation. As for the works of I. and II. categories, the administrator and authorised organisation may agree on temporary or permanent modification of the supervision over the extent, determined by this Regulation.
Article 7
The reports are being elaborated on the supervision, during the construction or reconstruction partial and total ones, during testing operation of the work partial and total ones, and during permanent operation of the work stage and total stage reports.
Article 8
Administrator is obliged to submit all the reports on the supervision to water management body, which is authorised to admit the work (hereafter „relevant water management body“); as for the works of I. and II. categories, he is obliged to arrange this submitting, through the authorised organisation.
Article 9
In the case, when during the construction or reconstruction of the work, the supplier uses such technology of the construction or reconstruction, that it would temporary create such construction, which captures, or is able to capture water, then the supplier is obliged to arrange the supervision, which is by this Regulation ordered to the administrator, in the relation to this part of the construction or reconstruction.

Weather and operation conditions are being monitored in the extent, necessary for evaluating all the monitored facts and realities.
(2) Measuring is necessary to be realised not only in the spots, which characterise average values, but also in the spots, where un-connected development of the facts could mainly appear, e.g. breakdowns in the foundations, changes in organisation and in connection of sealing and draining elements.
(3) Authorised organisation will determine usage of several methods of measuring, in case of doubt on reliability of the method of monitoring the most important facts and realities.
Article 11
As for the works of II. category, the extent of the supervision is the same as for the works of I. category, with the notification, that it is not necessary to monitor the facts and realities, the existence of which, respectively non-adequate change, may be explained, in time, by other fact or complete expression, e.g. from total soakings, total deformations or shifting. Measuring are regularly focused on characteristic profiles. Only such weather and operation conditions are being checked, which immediately explain monitored facts and realities.
Article 12
As for the works of III. category, the supervision is being realised by professional evaluating of the facts and realities and their development, which are being explored regularly only during by-passing around. Out of common measuring, only measuring the soakings, respectively also the pressures of the water and measuring total deformations on the surface of the work are being implemented. Out of weather and operation conditions, only rains and the air temperatures and the level of the water in the pond, are being monitored.
