Final Remarks and Next Steps

CDM 2015

HSE’s VIEW ON AREAS OF INCONSISTENCY

• Purpose & Function of Principal Designer

• Competence V SKE(T)

• Notification of Projects

• Role of Domestic Client

• Construction Phase Plans

CDM 2015

HSE’s Draft Construction Sector Plan

CDM 2015

CDM 2015 – HSE / RIBA philosophy and objectives • Architects can integrate

CDM from the start into the design.

• Significant not Normal Risks.

• Only document the Significant.

• Proportionality is a fundamental plank of CDM Differently

CDM 2015

CDM 2015 – HSE / RIBA philosophy and objectives

• Assist APS with PD & CDM Differently training & SKE for DRM & to reduce unnecessary industry bureaucracy

• Promote proportionate and consistent design risk management on architectural projects.

HSE’s VIEW ON PRINCIPAL DESIGNER ROLE

The Principal Designer should: • Strengthen Design Risk Management &

Cooperation

• Mirror the Principal Contractor Role in Achieving Coordination

• Ensure Information Flow

• Born out of Necessity!

• The CDMC was not working!

PD role – What has been the impact so far? • Designer definition in CDM is wide ranging

• Design community unsure of the role (ex-CDM-C’s & Insurance)

• Active vs Non-Active Designers (ex-CDM-C’s) – same criteria as PC role

CDM 2015

Who can be a PD? • Must be a Designer

with relevant SKE

• Must be In Control of pre-construction phase

• Can be an organisation or individual – but most usually an organisation (mirror the PC)

• No alternatives exist

Enforcement expectations

• For larger construction projects - regulation of the project, not just construction sites.

• Where failures, focus on immediate and underlying cause i.e. Beyond the Site Gate Dutyholders - Clients, Principal Designers and Designers, as well as training

• Construction phase plan

CDM 2015

Temporary Structures for Events

CDM 2015

Defined in BS 5975

An ‘engineered solution’ used to Support or protect an existing structure or the permanent works during construction. Support an item of plant or equipment. Support an excavation. Provide access.

What is Temporary Works?

CDM 2015

Earthworks Trenches, excavations, temporary slopes and stockpiles. Also Cofferdams.

Structures Formwork, falsework, propping, façade retention, needling, shoring, edge protection, temporary bridges, site hoarding and signage, site fencing.

Equipment/Plant Foundations Tower crane bases, supports, anchors and ties for hoists, MCWPs, crane and piling platforms.

Examples of Temporary Works

CDM 2015

In general, the products and services supplied by contractors are provided on a short-term or temporary hire basis. Long-term (over 28 days) or semi-permanent installation may become subject to other codes or regulations outside the scope of this document.

The erection of temporary structures at entertainment events falls within the definition of “construction work” in Regulation 2(1) of the Construction (Design and Management) Regulations 2015 (CDM).

CDM 2015

• Foundations — the ability of the ground to carry the loads transmitted

from the TW structure without failure or excessive deformation or settlement.

Three “Ps”

• Structural integrity — the ability of the TW structure to carry and transmit loads to the ground via the foundations without failure of the structural elements, including fixings and connections, and without excessive deflection.

• Stability — the ability of the TW structure to withstand horizontal or

lateral loading without sway, overturning or sliding.

John Carpenter describes three essential “Ps” for temporary works:

• People — Their competence and resource. • Process — An appropriate design, procurement and site-specific

methodology.

• Product — Quality.

Planning 1 of 3

Consider what the structure will be used for, what it needs to be able to do, who will use it and how?

Prepare a clear specification for the structure’s required use. This should include the technical details required to enable a design to be undertaken by your appointed TDS contractor(s) / designer (s).

TDS contractors / designers hired to design, supply, build, manage and take down a structure for you, should be competent and adequately resourced[1]. Provide TDS contractors / designers with relevant site information and/or allow them site access to carry out their own site assessments[2].

HSE’s Temporary Demountable Structures (TDS) - Stages, seating, marquees etc

CDM 2015

Your TDS contractor should ensure that the proposed structure has a design prepared by a competent person, which takes account of the use and conditions in which it is to be installed. Where a structure is to carry advertising / scrim, include this requirement in any design concept, specification and structural assessment. Novel or unusual structures may require additional testing by a TDS designer to demonstrate the integrity of the design. Whoever builds the structure should undertake an assessment of the likely construction hazards and risks.

Planning 2 of 3

HSE’s Temporary Demountable Structures (TDS) - Stages, seating, marquees etc

CDM 2015

To help with an assessment and to find out more about construction hazards and risks see:

• Falls from height[3] • Construction safety topics (including lifting operations and

vehicle safety)[4] • Health risks in construction[5]

Plan and work with your contractors to develop safe systems of working and make sure all significant risks on the site are properly controlled, e.g. use of cranes and lift trucks[6].

Planning 3 of 3

HSE’s Temporary Demountable Structures (TDS) - Stages, seating, marquees etc

CDM 2015

The assessments done under Planning (above) should serve as a guide on how to build and dismantle the structure safely. Make sure there is sufficient time and resources available to build and dismantle the structure safely. Use competent staff and have a suitable onsite operational management system in place to supervise and monitor safety compliance. A programme of works, including key safety checkpoints, can be helpful to communicate critical erection / dismantling stages to the site manager / crew bosses and operatives. Build the structure to the agreed design in accordance with a safe system of work. Arrange for the structure to be checked to make sure that it has been built according to the design.

Building and dismantling the TDS

CDM 2015

While TDS is in use • Have arrangements in place to inspect the structure for

deterioration during the time it is installed in line with a documented management plan and, if needed, arrange for remedial works.

• Any change in the proposed use of the structure or site conditions which may affect the structure’s suitability should trigger a design check for the new conditions. An example of this may be the requirement to add additional banners to a structure such as a PA tower. The organiser is responsible for ensuring this is done.

• Have arrangements in place to ensure that any measures required to keep the structure safe during use are implemented. For example, if the structure is susceptible to the weather, monitor and measure the local weather conditions. In adverse weather conditions, know what to do with the structure to protect its stability, eg when to open wind relief panels and when to evacuate.

CDM 2015

Don't • Take forward incomplete design concepts, as this could result in

last-minute modifications, leading to safety problems. • Build a structure on unstable ground. • Put advertising / scrim on a structure, if a competent person has

not approved it as being safe – it can affect wind loading and increase the risk of collapse / overturn.

• Use flammable fabrics.

CDM 2015

Problems with Temporary Works • Decisions on site are made with haste. • No Planning/No Procedures or inappropriate use of the procedures. • Poor or No Design. • Lack of competent contractor. • Inappropriate use of TW. • Changes are not properly managed.

CDM 2015

Problems with Temporary Works • Inadequate control of subcontractors.

• Lack of resources.

• Lack of adequate lateral stability.

• Inadequate foundations.

• Overloading.

• Poor construction.

• Do not appreciate the forces from ground or wind or

moving plant and heavy vehicles.

CDM 2015

Let’s make a difference!

• Better Design can reduce risks • Increased awareness of ill health! • New ways of working for HSE & Industry • Cultural change • Site conditions generally improved? • Better integration?
