Formwork Method Statement

1.    SCOPE


This procedure applies to the installation of formwork and the controls required during assembly, erection and final positioning of formwork used in Structural concrete operations.


2.    PROCEDURE


.1    All formwork activities will be carried out in accordance with the specification.


.2    After studying the structural drawings, the Project Engineer will plan for sizes, numbers and type of formwork to be used in consultation with the Structural Engineer, if required. Depending upon the programme, the number of repetitions will be decided.




External designers may be used for specific systems.


.3    Availability of formwork will be checked with the Procurement Manager and decision will be taken to buy, hire or reuse formwork material.


.4    During fabrication of formwork shutters, all dimensions shall be cross-checked with a view to avoiding corrective action during erection.


.5    Paint reference numbers on all panels to ensure their use in correct positions.


.6    Ensure that the props, shores, waling, bearers, clamps and tie rods are the right size and at the correct spacings. The Formwork designer shall check the falsework system with respect to load imposed on it and design parameters as laid down in the specification.


.7    Check that the falsework is securely braced and is on a firm foundation.


.8    Forms fastened to previously cast concrete must be tightly fixed to prevent grout loss. Cellular foam plastic strips can be used to make a seal.


.9    Check quality of shutter lining, tightness of bolts and wedges, built-in items, inserts and other embedments.


.10    Tie – rod holes to be made in the formwork shall be neat so that they can be patched or plugged later on.


.12    Particular attention will be paid to the rigidity and line of stop ends and joint formers.


.13    Remove all tie-wire clippings and nails, which may stain both the formwork and the concrete.


.14    Ensure that adequate access and working platforms are in place for the concreting gang and that toe boards and guardrails are provided.


.15    A spreader or lifting beam shall be used to prevent distortion when placing formwork.


.16    Adjustable steel props shall be erected in plumb and verticality of props checked using a spirit level.


.17    A prop should not be used if it is bent, creased or, rusted or has a bent head or base plate, damaged pin etc.


.18    Proper release of agent shall be used so that it can be removed without damaging the surface finish of the concrete.


.19    New timber and plywood forms shall be given first coat of the appropriate release agent 36 hours in advance, then a second coat just before they are used. Avoid excessive use of release agent as this can cause staining or retardation of the concrete.


.20    A close watch should be kept on all wedges and fastenings. Make sure that they do not work loose. Grout loss is an indication that some movement has occurred.


.21    When unsleeved tie bars are being used, ease them slightly before the concrete sets, and remove them as soon as it is safe.


.22    Striking the Formwork:


i)    Always obtain approval before striking the formwork in the form of Appendix CONC/04/A.


ii)    Ensure adequate safety measures while striking formwork.


iii)    Cleaning the face of forms shall start as soon as they have been struck.


iv)    Good storage is essential to ensure that formwork can be used again.


v)    Paint code numbers on them so that they can be readily identified when next needed.


.23    Safety During Formwork Operations:


i)    The weights of large prefabricated sections of formwork should be marked on them so that the lifting capacity of the crane at the working radius is not exceeded. Lifting points are usually provided.


ii)    If necessary, a spreader or lifting beam shall be used to prevent distortion.


iii)    Where lifting is done by the vertical soldiers, check that they are adequately connected to the walings.


iv)    Fire extinguishers in working order shall be in close proximity to the stored formwork.

Handle Scope Change Requests with Appropriate Discipline

Handle Scope Change Requests with Appropriate Discipline


 


When a project begins, you must gain agreement with your sponsor on project scope. The scope is defined at a high-level in the Project Charter or Project Scope Statement. At a low-level, the scope is detailed through the approval of the business requirements. Once these two documents are approved, you have enough information to understand scope through the remainder of the project.



However, like death and taxes, change is inevitable. There are two reasons. First, it is almost impossible to define ahead of time exactly what the final solution should look like, and so the requirements may change as the solution starts to evolve. Second, overall business conditions change over time. Some of this business change will force changes to the project scope in ways that are not known ahead of time.


 


Therefore, what do you say when the inevitable changes start to come in? If you say yes without taking into consideration the consequences to the project objectives, you may increase your chance of failure. If you say no, you may introduce conflict with the client and run the risk of delivering a solution that does not meet the client’s needs or satisfaction.


 


The right approach to scope change management is to not say “yes” or “no”. The better response is to follow a scope changing management process. This process should include:


scope change


 


-          Evaluate and understanding the business value of making the change


 


-          Estimating the impact on the project objectives like cost, time, and scope….etc.


 


-          Taking the final information to the project sponsor (or their designate) for an approval decision.


 


Scope change management is really the process of letting the sponsor make the decisions – once they understand all the facts and implications.


 


You should establish scope change procedures based on the size of the project. For small projects (maybe less than 250 effort hours or 25 calendar days), you do not need to worry about scope change as much. The project will likely start and end before the business can change much and most of the requirements are probably fairly well known. The project manager can quickly evaluate a small change request and work with the sponsor to determine if it should be accommodated.


 


For larger projects, scope change is a big deal, and must be managed probably. All stakeholders, including the sponsor, must be sensitized or informed to understand when a scope change request made. The scope change request process may have a number of steps and require a template or two. If the sponsor approves the change, the budget and timeline are changed accordingly. If the change is not approved, it is noted as such and the project continues on its way. You might be surprised how often the sponsor does not approve the scope change, once they understand the impact to the project.


 


Summary


 


Many project managers do a poor job of managing scope because they do not want to offend the client. However, that should not be a part of the scenario at all. Instead,  the project manager’s job is to make sure the scope change management process runs effectively,  and that the project sponsor has the information they need to make the best decision possible on  whether the scope change should be accepted ,you as a project manager must believe this rule “at begins of any project you and project sponsor have a progress elaborated project scope ,so it can changed at any time

Block work Method Statement

1.    SCOPE


This procedure provides a method of control for construction of block masonry work in order to achieve compliance with the contract specifications and drawings.


2.    PROCEDURE


.1    All precast concrete masonry blockwork will be carried out in accordance with the specification and Project Quality Plan.


In any circumstances where specifications are not provided or they are in any way incomplete, the matter shall be referred back to Consultant’s representative for additional information.



.2    Checks Prior to Start of blockwork:


i)    Ensure that the area to receive the blockwork is as per the contract drawings and approved finishing schedule.


ii)    Check if preceding activities have been inspected and approved.


iii)    Ensure that blocks are procured from approved manufacturer (s). Except where otherwise approved in writing each material shall be obtained from a single source.


iv)    Source certificates shall be obtained for all raw materials e.g. sand, cement and blocks to show compliance with the contract specification.


.3    Handling and Storage of Materials:


i)    Blocks shall be delivered to site palletised, off loaded as near to the point of use as practicable on a clean hard surface free from contamination by mud or surface water.


ii)    Cement shall be stored off the ground, kept dry and used in order of delivery.


iii)    Store metal ties and straps under cover and protect them from damage and distortion.


.4    Preparation of Work, Materials and Components:


i)    When the materials and components are distributed to the work area, ensure that the structure is not overloaded.


ii)    Plan for scaffolding material required for block work at heights. Plan for additional manpower for lifting blocks at heights.


iii)    Set out anticipating the position of openings etc. in the work above to avoid unnecessary cutting and adjustment of masonry units leading to incorrect or uneven bonding.


.5    Preparation of Mortar Mixes:


i)    Mortar shall be mixed by machine except for small quantities only (not containing plasticiser). Hand mixing (if permitted) may be done on a watertight platform.


ii)    When mixed at site, batch boxes shall be used to ensure correct and consistent mix proportions.


iii)    Use mortars (other than retarded mortars) within 2 hours of mixing or as specified.


.6    Building Blocks Walls:


i)    Build block work within permissible deviations as specified.


ii)    Unless otherwise specified/permitted, lay blocks on a full bed of mortar and fill all joints. Keep courses levelled and perpend vertically aligned. Plumb quoins and all faces as the work proceeds. It is preferable to Align vertically every fifth or sixth perpend and `even out’ the size of Intermediate joints. Try to keep horizontal joints of uniform thickness.


iii)    Do not carry one course more than the height specified in the contract specifications.


iv)    Rake out joints as work proceeds, on all faces to be plastered or rendered. This will provide a good key for the coating.


v)    If pointing is specified, the mortar used for the pointing should not be stronger than that used when constructing the wall unless specified otherwise.


vi)    All blockwork shall be bonded to adjacent reinforced concrete structures by means of galvanised mild steel cramps at specified spacing unless specified otherwise.


vii)    Partitions shall be bonded to main walls by toothing as specified in the contract.


.7    Chases and Holes:


    Cut chases and holes neatly and without damaging the walls as per the following unless specified otherwise:


i)    Chases in blockwork to be less than 75mm.


ii)    For hollow units maintain a minimum of 15mm thickness between bottom of chase and void.


iii)    Do not cut horizontal or raking chases to a depth exceeding one-third the thickness of the single leaf in walls or leaves contracted of solid units.


iv)    Holes shall not exceed 300mm x 300mm unless specified otherwise.


v)    Do not cut chases back-to-back exceeding the dimensional restrictions in (i),(ii) and (iii). Offset such chases in line by a distance at least equal to the wall thickness.


vi)    It is preferable to use mechanical rotary cutters, particularly when it is necessary to avoid heavy impact and vibration. The number and position of chases shall be strictly in accordance with the specification since unauthorised chasing might adversely affect one or more of the functional requirements of the walls e.g. its loadbearing capacity.


.8    Appendix FINI/01/B shall be used to record deliveries of blocks if required by the specification.

CONSTRUCTION JOINTS IN IN-SITU CONCRETE METHOD STATEMENT

CONSTRUCTION JOINTS IN IN-SITU CONCRETE METHOD STATEMENT


1.    SCOPE


 The scope of this procedure outlines methods to be used for constructing effective and durable construction joints in accordance with the contract specifications.


 2.    PROCEDURE


.1    In some cases CLIENT shall have to prepare shop drawings proposing location and type of construction joints and obtain approval from the Consultant’s representative before proceeding with the work.


.2    Horizontal Surfaces:


     Laitance on the surface must be removed from the concrete in order to ensure that a good bond will be achieved when fresh concrete will be placed against it. Following methods may be used for removing laitance from the top of walls and columns unless specified otherwise in the contract:


 i)    Washing and Brushing:


 The easiest way is to brush off the laitance while the concrete is still fresh but has stiffened slightly. Brushing shall be commenced between one to two hours after placing of concrete. Site operatives shall have brushes with soft and hard bristles so that it can be used depending upon stiffness of concrete. Care shall be taken that the brushing shall not be harsh which will dislodge the coarse aggregates. In case laitance has hardened but is still green, a wire brush should be used.


 ii)    Air and Water Jet:


 Laitance can be removed by directing a jet of air and water onto it. This method can be used up to six hours after placing or possible longer but the site operative must make his own judgement while adopting this method. This operation must not start too soon because it might dislodge coarse aggregate particles.


 iii)    Mechanical Scabbling:


 If laitance is too hard to be removed by wire brushing, mechanical scabbling can be tried using small percussion power tools. This method can be applied after 3 days when concrete has hardened sufficiently. Care shall be taken not to weaken the coarse aggregates.


iv)    Abrasive Blasting:


 Wet or dry abrasive blasting can be used to expose the aggregate but special safety precautions shall be taken while using sand.


.3    The most appropriate time for treating the joints is a matter of judgement, because it depends on the rate of setting and hardening (which is itself dependent on the temperature of the concrete).


.4    Where there is likely to be even a short delay before placing the next concrete pour, protruding reinforcement should be protected. Before the next pour is placed, rust, loose mortar or other contamination should be removed from the bars.


.5    Vertical Surfaces:


i)    Stop Ends/Expanded Metal Mesh:


Vertical joints in walls, beams and slabs are usually formed at a stop end in the formwork. Stop ends shall be located where the reinforcement is least dense. Holes for reinforcement in stop-ends are a potential weakness because grout loss can occur. In lightly reinforced sections and where starter bars are acceptable, this problem is frequently avoided by bending bars so that they run along the inner face of the stop-end. When the stop-end is removed, the bars are cut out and straightened. However, the cutting out and straightening can damage the concrete and cause local loss of bond with the bar, especially if this is carried out within 48 hours of placing the concrete.


 Proprietary stop-ends have been developed which overcome this problem by encasing the bent bars in expanded plastic foam. The foam can easily be removed and the bars strengthened by means of a steel tube. Take particular care not to use impact to straighten bent steel at stop-ends as this can cause brittle fracture.


 Permanent forms of expanded metal are increasingly employed, particularly in deep slabs. The concrete surface produced by such system is very irregular and does not normally require any surface preparation. Where a very high workability mix is being used (slump greater than 200mm) with expanded metal formwork, care should be taken to avoid over – vibration at the joint as this may cause grout loss.


 ii)    Formwork:


 Formwork for subsequent concrete pours must be accurately aligned and well fixed so that there is no grout leak which results into discoloration and honey combing. Strips of foam rubber or polyurethane unless specified otherwise can be fixed around the edge of the hardened prepared joint.


 .6    The methods explained previously i.e. washing and brushing, mechanical scabbling and abrasive blasting can also be used in case of vertical joints. However special care shall be taken not to damage the leading edges (leave a margin).


.7    Watertight Construction:


i)    In watertight construction unless specified otherwise, flexible waterbars of specified details can be used. Care shall be taken while concreting so that all waterbars are securely tied to avoid its folding during concreting.


 .8    Cold Joints:


 i)    Cold joints normally occur during the concreting operation when a delay in placing adjacent concrete has occurred and earlier concrete placed has stiffened.


 ii)    A simple test can be used to determine whether concreting can proceed. Embed the poker vibrator into the existing concrete to examine the condition of concrete. Where the action of the poker has left a distinct hole, concreting operations should not continue. In this case the joint face can be prepared by one of the methods described above for horizontal construction joints.


 .9    Placing the Fresh Concrete:


 i)    Particular care as explained below shall be taken while placing and compacting new concrete on or against the old:


ii)    Any dirt or dust from the surface of the hardened concrete shall be removed preferably with a compressed air hose. As a safety precaution site operatives must wear safety goggles. This cleaning shall be done before new formwork is fixed because not only access be easier than but also dirt might otherwise stick to the new formwork.


iii)    While fixing a new formwork extra dirt is created which can be cleaned after removing a stop end – which will make it easy to be swept or blown away.


.10    Joint Sealing:


 i)    Where the structural component containing the joint is to be exposed to the external environment, the joint has to be sealed to prevent ingress of water. For type and method of application refer to the contract specifications and/or manufacturer’s instructions.


  3.    DOCUMENTATION


 Following documentation and forms may be maintained as a minimum pending on Project Quality Plan requirements and contract specification.


 i)    Contract and/or approved workshop drawings.


i)    Manufacturer’s test certificates (in case of sealants and


waterbars).


iii)    Request for Consultant’s consent/approval.


 The above referenced documentation where appropriate will be retained in the HEE archive for the prescribed period of time.

Concrete Pavings Method Statement

1. SCOPE


The scope of this procedure covers the control of installation of in-situ concrete paving surfaces including finishes to ensure compliance with the contract specifications.



2. PROCEDURE


.1All activities connected with concrete pavings will be carried out in accordance with the contract specifications. In any circumstances where specifications are not provided or unclear, clarification will be sought from the Consultant’s representative.


.2 Where necessary a method statement shall be prepared and approved by the Project Director/Manager. It shall include:


i)    The agreed tolerance on level and surface regularity.


ii)    Site protection and safety.


iii)    Mix design details for wearing surfaces.


iv)    Method of placing, compacting and finishing concrete.


v)    Method of curing.


.3Source certificates of basic constituents of concrete to be obtained from the supplier to verify compliance with the specifications.


.4Ensure that the proposed sequence of work is commenced in compliance with the contract programme. While framing the construction schedule, additional allowance shall be made for the following:


i)    Laying under floor services,


ii)    Curing and drying of the base concrete before the flooring is laid.


iii)    Curing of the flooring,


iv)    Period of protection of the completed floor from damage by other trades, including restriction of access.


.5Special care while laying concrete finishes and wearing surfaces:


i) Where a structural concrete slab itself forms the flooring or where a topping is laid monolithically or bonded to a hardened base, the wearing surface shall be adequately protected against damage during subsequent building operations.


ii) In hot or drying conditions, care shall be taken that the concrete mixes do not stiffen or dry out to an extent that prevents full compaction. After compaction and finishing, the surface shall not be allowed to dry out quickly and this may be achieved by protection by plastic sheeting or other suitable means. In addition where concrete is laid in the open, its surface shall be protected from the effects of the sun and wind to limit the risk of cracking.


iii) Compaction of concrete shall be carried out in such a way that an excess of `laitance’ is not brought to the surface.


For the highest abrasion resistance, the final trowelling shall be made when considerable pressure is required to make any impression on the surface. However, excessive trowelling should be avoided to prevent the production of a polished or slippery finish. Water shall not be applied between trowelling operations as this may cause surface weakness.


iv) Curing shall be done as specified.


v) When topping is laid separately and bonded, the surface of the base shall be thoroughly prepared as specified to ensure proper bond between the topping and the base concrete.
