STRUCTURAL SPECIFICATIONSTABILITY· Responsibility: Maintain the stability and structural integrity of

the Works and adjacent structures during the ContractDRAWINGS· Do not scale for construction purposes.· Drawings is to be read in conjunction with Structural

Specifications.· Refer to architects drawings for setting out information.· Dimensions in mm (unless otherwise stated).· Drawings is to be read in conjunction with appropriate

consultants information.· Sections donated 'T' (e.g. T26) are typical sections intended

to provide relevant information but may not show the exactarrangement.

GENERAL NOTES· The drawings are based on limited site dimensions (a full 3D

survey of the existing structure has not been provided. Thecontractor must check any critical dimensions before orderingor cutting any structural elements to ensure fit.

· Where sections show structural members in relation to floorlevels these are indicative - refer to architects drawings forlevels.

· All water-proofing and damp-proofing works to architectsdetails. Where these drawings show waterproof or dampproof membranes they are simply intended to indicate theirposition in relation to the structure. The membranes havebeen designed, specified and detailed by the architect or themanufacturers and to be installed as per their drawings.

· All floor separation details and acoustic insulation are to thearchitects details.

· All insulation requirements are to architects requirements.Insulation is not always shown on the structural drawings,where it is shown it is for indicative purposes only.

EXISTING STRUCTURES· Duty: Check proposed methods of work for effects on

structures inside and outside the boundary.· Supports: During execution of the Works:

- Provide and maintain all incidental shoring, strutting,needling and other supports as may be necessary topreserve stability of existing structures on the site oradjoining, that may be endangered or affected by theWorks.

- Do not remove until new work is strong enough tosupport existing structure.

- Prevent overstressing of completed work when removingsupports.

Standard: Comply with BS 5975

RISK ASSESSMENTAs the designer of the structure for this project an assessment of the construction risks has been carried out and it is considered that a competent builder would be able toconstruct this project using appropriate temporary works. Attention is drawn to the table of element sizes which provide the approximate weight of the steel elements.Any particular risks are noted in the appropriate location in the drawings with the following symbol:

TIME AND COST RISKS

Where indicated on drawings open up structure to confirm assumptions at the start of the project.

CONSTRUCTION RISKS (CDM REGULATIONS) ACTION

Check details at the earliest opportunity to ensure sections fit before ordering steel.

Check foundations depths at the earliest opportunity.

Check availability of scheduled members at earliest opportunity.

OTHER RISKS ACTION

Compressive Strength of Masonry too low Check existing masonry meet requirements where noted on drawings (eg. concrete blocksand not aircrete blocks (breeze blocks, celcon))

Poor construction A competent builder should be employed.

Timber bracing not installed to roof Refer to timber specifications for bracing requirements.

External steel corrosion Refer to steel specifications for proprietary steel protection.

Holes reducing strength in structural members Refer to material specifications prior to any cuts and holes into members.

Cantilever overturning

Restraint straps not installed

Check if any construction sequence or specific connections are mentioned in drawings priorto loading any cantilever members.

Refer to timber and masonry specifications.

Check for the presence of any sewers before commencing any ground works.

Pitching plates Ensure correct number and specification of bolts are installed.

!

Use of cold rolled steel instead of hot rolledsteel

Ensure correct grade (S355 and not S235) of steel is ordered and received from the steelfabricators
