Editor: Arun Syam

EDITORIALIt has long been recognised that the costing of structuralsteelwork cannot be accurately determined by rates based on$/tonne, weight/square metre, etc – i.e. by weight conceptsalone. The costs associated with various connection types,materials procurement and the value adding processes ofdetailing, fabrication, coating, transportation and erection areessentially process dependent. Current design optimizationtechniques generally utilise the steel weight criterion whichdoes not necessarily produce minimum cost solutions.However, rational methods of costing have not been readilyavailable.

The paper contained in this issue of Steel Constructionentitled “Costing of Steelwork from Feasibility through toCompletion” considers a new method of costing steelwork.The method examines costs associated with each processand breaks it up into costs related to steel supply, fabrication,surface treatment and erection. The paper also illustrates themethodology by several case studies.

As the new costing method is published in the journal forfurther industry comment, the authors would welcome anyfeedback on its details and application. Additionally, readersshould note that the regular Steel Construction “Current CostIndicators” – which was generally based on a $/tonne method– has been withdrawn. This has been due to various reasons– the primary one being its inconsistency with the preferrednew costing method.

STEEL CONSTRUCTION VOLUME 30 NUMBER 2, JUNE 19962

1. INTRODUCTIONA considerable amount of effort is devoted during thedesign process to optimizing the design to achieve a min-imum cost solution. The measure traditionally used tojudge the economy of the design is the quantity of steel inthe structure expressed as a weight per square metre offloor area or per cubic metre of cubic content (Hart Henn& Sontag (1)). Therefore, the optimization of a design hasmeant the minimization of the quantity of material in a pro-ject. This has permeated all facets of design, constructionand research. For steel structures, the current method ofcosting steelwork on the basis of a rate per tonne has leadto this concentration on minimum mass solutions. YetGirardier (2) indicates that the material cost representsonly 40% of the total cost of the steel frame. The remain-ing 60% of the cost represents the value added in fabrica-tion and erection which has been very difficult toaccurately quantify. This latter component has often beenneglected in design. For example, the cost of stiffening apenetration can add considerably to the cost a beam, yetit is often not considered worthwhile to carry out a designto determine the level of stiffening required. By compari-son, a considerable time is typically spent minimizing thesize of the member.

Various proposals (Australian Institute of SteelConstruction (3), Hogan and Firkins (4)) have been madeto remedy this situation and some worthwhile generalprinciples have been developed. These have includedadvice such as: weld in the fabrication shop, bolt on site;adopt simply supported connections not continuous.Whilst these qualitative principles will generally apply,they do not allow the particular situation to be adequate-ly investigated. There has also been some industry skep-ticism on whether the benefits of adopting good designprinciples were being passed on to the client in the formof lower prices. In fact, it was frequently perceived thatgood design was costing more, as the design was oftenheavier and hence on a rate per tonne basis it would costmore. Firkins and Hemphill (5) advised on work hours pertonne for various types of work and whilst this was arefinement, it translated into a rate per tonne. It was anaverage rate and did not allow details to be costed withsufficient accuracy to allow comparisons to be undertak-en. This method has the additional disadvantage that it isvery dependent on the experience of the estimator in theparticular type of work.

To help give a better understanding of the total cost of

steelwork, Watson and Buchhorn (6) developed conceptsfor costing steelwork in which components of the cost weretaken into account. The concepts proposed were similar tothose practices adopted by the professional fabricators.The method was further developed (Watson, Dallas & Main(7); Main, Watson & Dallas (8) and Watson & Dallas (9))into a practical and rational method of costing steelwork.During this period extensive consultations were undertak-en with all sections of the Australian construction industrywhich lead to the method being refined and extended tocover most types of steel construction. The steel construc-tion industry has been very supportive of these develop-ments as the system reduces the contractual risks to thefabricator and also reduces the cost of tendering by pro-viding a format consistent with the fabricator’s method ofestimating.

Tizani, Davies, Nethercot and Smith (10) have been devel-oping knowledge based engineering systems to carry outcomparative costing on different space frame systems.Their approach is similar to that discussed in this paper.

This paper explains the method and uses case studies toillustrate the insight that can be achieved into factors influ-encing costs. Extensive tables of indicative unit rates aregiven so that most structures can be costed. The applica-tion of the method at various stages of the design and con-struction process is demonstrated with particular attentionbeing given to extending the method to cover early stagesof design. Indicative sizes and costing are given for portalframe industrial buildings, carpark, office and retail floorsto assist with costing at the early stages of design.The pro-posed method presented has not yet been fully extendedto cover all plate structures such as bins and silos.However the principles can readily be applied to suchstructures.

2. THE CURRENT METHODWhen pricing a job, fabricators determine the cost of thesupply of materials, the number of hours involved in fabri-cating steelwork, and the costs for surface treatment anderection.These costs are then summed and divided by thetotal number of tonnes to determine a rate per tonne to beincluded in the tender documents.Therefore the rates rep-resent an average across the total job and do not provevery useful in determining the cost of variations or refiningdesigns. The format of the breakup is guided by theAustralian Standard AS1181- 1982 (11) for civil engineer-

ing projects and the Institute of Quantity Surveyors andMaster Builders’ – Construction and HousingAssociation’s (12) Standard Method of Measurement(SMM5) for building projects.

Table 1 shows that there is a great variation in cost ofsteelwork on a dollars per tonne basis. The variationreflects the complexity of the work to fabricate and erect.Toovercome this wide spread, rates have been developedand published (Cordell (13), Rawlinsons (14)) for varioustypes of work.

Poulos (15) investigated the costs of three different portalframe designs for a 2,000 square metre building with aspan of 30 metres. The results are summarised in Table 2and show a 36% variation in tonnage rates over the threedesigns. This illustrates that even for standard structuresthe current method cannot give accurate and reliable cost-ing of projects. Whilst the ‘conservative’ design increasedthe tonnage by 12% over that required for the ‘good’design, the total cost of the frames increased by only 6%.This was because only the steel supply component of thecost increased as there was no difference in the cost ofthe shop drawings, fabrication, transport and erection.However, for the skinny design a corresponding decreasein the mass of steel from the ‘good’ design increased thecost of the frame by 15%. This increase was caused bymore complicated knee connections, additional fly bracingand additional costs in erecting flimsy members.Therefore the current method, which leads to minimisingweight can result in more costly designs.

3. PROPOSED NEW METHOD OFCOSTING

As accurate costing is one of the essential features neces-sary to design and construct economical structures, it wasdecided to develop a rational costing method which willovercome these deficiencies.The goals of the new methodare to:

• give a more reliable and accurate method

• provide a continuity of approach from initial projectcosting through to fabricator’s detailed costing

• provide a clearer focus on the elements that will havea significant effect on the final cost

• allow reliable determination of cost of contract varia-tions

• provide a methodology which is simple to understand.

In order to achieve these goals, the costs are divided intofour components: steel supply, fabrication, surface treat-ment and erection. Costs represent rates received fromfabricators and as such, they do not include the builder’smargin. The indicative costs given in Appendix A areapplicable for projects where the steelwork cost (supply,fabrication and erection) is greater than $150,000.The cur-rent hourly labour rate adopted for the tables is $40.00.

3.1 Steel SupplySteel supply covers the supply of all materials including hotrolled, welded, cold formed and tubular sections, plate, aswell as items such as bolts and shear studs. (ReferAppendix A1 for tables.)

Sections are costed on a rate per metre basis. This bringsthe costing of hot rolled sections into line with cold formedsections, such as purlins and tubular sections, which havebeen traditionally been sold on a per metre basis. Anotheradvantage of this method is that it allows a very quick com-parison to be undertaken on different sections capable ofcarrying the same load.

Plate is costed on a rate per square metre basis.This givesa more realistic measure than dollars per tonne and allowsfor any changes in the cost of steel with thickness to behighlighted as shown in Figure 1.

Wastage has not been allowed for in the rates given as itcan be minimised in the design process. For instance,

Design Description Frame Mass Cost $ / tonne(tonnes) ($)

‘Good’ Design 20.2 45,646 2,260

‘Conservative’ Design 22.6 48,530 2,147

‘Skinny’ Design 18.0 52,679 2,927

Table 2. Comparison of costs for different designs for 2,000 square metre portal frame building (span 30m).

Item Cost ($) / tonne Variation(times lowest cost)

Steel supply 900 - 1,300 1.4

Shop detailing 50 - 500 10.0

Fabrication 200 - 2,000 10.0

Surface treatment 0 - 750 ∞Transport to site 50 - 200 4.0

Erection 150 - 700 4.7

TOTAL 1,350 - 5,450 4.0

Table 1.Typical range of tonnage rates.

there is often the opportunity to eliminate wastage, or atleast minimise it, by designing with standard lengths inmind (Refer Appendix B and BHP Steel (16) for details ofstandard lengths), or by providing sufficient time in the pro-ject programme for the steel to be supplied cut to the spec-ified length by the manufacturer. Wastage is typically 2-5%for a project. By combining the requirements for a numberof smaller projects the wastage level can be minimised tosimilar levels to that of larger projects.

3.2 Fabrication

3.2.1 IntroductionFabrication covers each activity after the delivery of steelto the fabricator to the delivery of steel to site. It includes:shop detailing; fabrication of end connections, items alonga member, compound members; and transport. Surfacetreatment is covered as a separate item in Section 3.3.

It is proposed that all costing be activity based. The timerequired to undertake each activity is therefore used. Thishas the advantage that it is relatively constant acrossAustralia and is not subject to significant fluctuations withthe changing economic times. With relatively expensivemachines, like beam lines, the cost has been convertedinto equivalent work hours to include capitalised costs andhence simplify the method. Consumables, minor equip-ment, overheads and profits are included in the hourly rate.

The hourly rate is readily obtainable and allows costs to beupdated to reflect the local economic situation. It was foundthat a high level of accuracy can generally be achieved byproviding rates for three different section weight ranges.The fabricator will cost the job in finer detail when tender-ing on a project. Fabrication rates are given in AppendixA2.

3.2.2 End ConnectionsIt is proposed that all the hours associated with a connectionare allocated to the supported member. Appendix A2.1gives tables of rates for commonly used standard connec-tions.

3.2.3 Work Along a Member This covers work along a member which is not associatedwith connection to another member. Examples includepurlin and other cleats, penetrations, architectural connec-tions. Refer to Appendix A2.2 for rates.

3.2.4 Compound MembersCompound members are members built up from individualcomponents and include three plate members, trough andbox girders, box columns, trusses, vierendeel trusses andbattened columns. These members form two different cat-egories:

• Members whose costs of fabrication are related to theirlength. Examples of these include three plate membersand box columns. The cost of fabricating these mem-bers is given as a rate per metre.Table A2.2.4 gives therates for fabricating a three plate girder.

• The costs of fabricating trusses, vierendeel trussesand battened columns are dependent largely on thecosts associated with each joint. Examples of fabrica-tion costs for different types of trusses are given inTable A2.2.5.

3.2.5 Other Fabrication ItemsIt is not possible to fully cover every detail in tables such asgiven in Appendices A2.1 and A2.2.To assist in developingcosts for details not covered, some elemental costs are

STEEL CONSTRUCTION VOLUME 30 NUMBER 2, JUNE 1996 5

included in Appendix A2.3. These costs may need to besupplemented with advice from fabricators. The costsgiven in Appendix A2.1 and A2.2 are complete costs for thefabrication of the item and hence already include the costsgiven in Appendix A2.3.

3.2.6 Shop DetailingWatson et. al. (7) referenced the cost of shop drawingsback to the number of hours of fabrication. The ratio variedfrom 1 hour of shop detailing for every 4 hours of fabrica-tion for portal frame work, to parity for complex work involv-ing significant variations.

Main et. al. (8) gave guidance on the number of hoursrequired to draw marking plans, individual members, com-ponents and carry out checking. The estimator is thenrequired to determine the number of drawings.

The time to prepare shop drawings is dependent on thequality of the contract drawings, the complexity of the pro-ject and the amount of repetition.There has been a declinein the quality of contract drawings as fee pressure hasintensified. This is usually a false economy, as the shopdetailer must fill in the gaps in information, and this resultsin significantly increasing the costs of shop detailing.

Where members are identical, the costs of detailing aresignificantly reduced as the member is only drawn once.Minor differences in details add to the cost, as they must benoted on drawings or the members redrawn. When sever-al people are working on a project, there should be com-mon detailing across the whole project, otherwisemembers will be required to be redrawn needlessly.

Due to difficulties in determining the number of identicaland similar members early in the design process, it is rec-ommended that a method of relating the cost of detailing tothe cost of fabrication be used at this stage (refer TableA2.4.1). As the design is finalised, the estimate can berefined if it is based on the number of shop drawings (referTable A2.4.2).

3.2.7 Transport The cost of transport is directly related to the number oftruck loads of steel, the size of the loads and time taken toload, transport and unload the steel. Hence the cost isrelated to both the weight and volume of steel and to alesser extent the distance from the site. Table A2.5.1 givesthe rate per member to transport beam and stick typesteelwork.

The total typical travel time for a city delivery is 9 hours perload which is composed of the following components: timefrom depot to fabrication shop (1.0 hour); time to load steel-work on truck ( 2.5 hours); fabrication shop to site (1.5hours); waiting time at site and the time to unload steelwork(3 hours); travel time back to depot (1 hour).This highlightsthe significant time and subsequent cost savings that couldbe made by palletising fabricated steelwork.

Transport costs for other types of work can be calculatedusing the above principles. When transporting bulky itemssuch as three dimensional trusses, the volume will deter-mine the number of items that can be carried on a truck.

If the steel is galvanised or painted at an external shop, thecost of transport is almost doubled as the steel is trans-ported twice, once to the galvanisers or paint shop andthen to site. It is recommended that this additional cost be

included in the surface treatment cost.

3.3 Surface TreatmentSurface treatment covers all forms of treatment to the steeland includes painting, galvanising, fire spray, intumescentpaint and fire rated board systems. A rate per square metreof applied treatment has been adopted as the appropriatemeasurement. Differences in handling, thickness of zinc ingalvanising and thickness of fire spray due to changingsurface to mass ratio have been allowed for by giving ratesfor three different mass per metre categories as shown inAppendix A3. For the fire rated board systems, the project-ed area will generally be applicable. Appendix C gives thesurface areas for standard sections which makes the pro-posed method very simple to apply.

3.4 ErectionThe key determinant in the cost of erecting steelwork is thenumber of lifts that are required. Once the crane size isdetermined based on the dual requirements of lifting radiusand mass of component, it costs virtually the same to lift avery light member as a heavy member. The cost of erect-ing bigger sections has been increased to allow for theextra time for the end connections and to plumb the steel-work. Appendix A4 gives typical costs per member for por-tal frames and multi-storey buildings.

For other types of projects it is recommended that thecosts be derived using the same methodology.This is illus-trated by the bridge example in section 3.5.2.

4. CASE STUDIES

4.1 Case Study No. 1 – Portal FrameThe costing of an internal bay of a 2000 square metrewarehouse with portal frames at 9 metre centres and 6metre eaves is given in Appendix D1. This shows thatapproximately 60% of the cost of the building is in thepurlins and sheeting. However, the time spent in optimisingdesigns of portal frames has generally been on minimisingthe tonnage in the frame which represents only 20% of thecost of the building. As was shown in section 3, this effortcan be counter productive and lead to more expensivedesigns.

An alkyd primer (red oxide zinc phosphate) paint systemwas chosen as providing adequate corrosion protection.This paint system is usually applied in the fabrication shop.However, if an inorganic zinc silicate system was adopted,the steel would normally have to be transported to a spe-cialist contractor to be grit blasted and painted. The totalcost of painting would have increased four fold with the useof inorganic zinc silicate.

It is normal practice for the fabricator to be responsible forthe supply of cranes on industrial projects and thereforethis has been allowed for in the costing.

This costing method allows the determination of the mosteconomical spacings of the portal frames and purlins.

4.2 Case Study No. 2 – Multi StoreyBuilding

A ten level office building with a floor plate of 1000 squaremetres net per floor was chosen to investigate the costingmethod (refer Figure 2). A conventional layout with beamsspanning from the perimeter to the core was prepared(refer Figure D2.1). A 120mm deep slab on 1.0mm BondekII spanned 2.8 metres between the steel beams. The floorstructure was required to accommodate a major air condi-tioning (A/C) duct around the reinforced concrete core. Asteel depth limit of 300mm was adopted in this area tomaintain a reasonable plenum height (the height fromunderside of ceiling to the top of slab above). Also, the A/Cduct layout and flexibility requirements indicated web pen-etrations at third points in the typical secondary beams B1and B7. Other internal beams were specified to have smallcircular penetrations at third points for services. The floorbeams were designed in accordance with the soon to bereleased composite beam standard AS2327.1-1996 (17).Beams were cambered for their self weight and the con-crete slab weight.

The initial design, referred to as Design A, had an overallsteel beam intensity of 31kg/sq.m. This scheme involvedstiffened web penetrations in B1 and B7 which were460UB67.1 beams. Alternatively, adopting 530UB82.0beams in these locations eliminated the need for stiffeningat the web penetrations. This scheme had a beam steelintensity of 35kg/sq.m and is referred to as Design B.

Appendix D2 gives a full costing of beams for Design A andthe varied beams in Design B, using the proposed method

of costing. The results are summarised in Table 3.

When costing according to the proposed method, the steelframe cost of Design B is slightly lower even though it isheavier than Design A. However traditional methods ofcosting based on a constant dollars per tonne rate wouldhave quickly ruled out Design B, as it was heavier.

For Design A, the stiffener supply and fabrication costs atthe penetrations totalled $190 per penetration comparedto $32 for Design B with its unstiffened penetrations.Whenthe extra beam supply and firespray costs associated witha 530UB82.0 were also included, a similar overall costresulted. Steel cost includes supply, shop detailing, fabri-cation, fire-spray, transport and erection of structuralsteelwork.

The fire spray cost for both schemes represented about20% of the total steel-frame cost. Bennetts and Thomas(18) showed that on the 40 storey, 140 William Street,office building in Melbourne that if a reliable fire sprinklersystem was installed and the passive fire protectionremoved, the building would be safer than a building meet-ing the building regulations. The fire spray on this buildingwas subsequently not reapplied during the refurbishment.

The shop detailing was costed by estimating the number ofdrawings. It was decided that each beam type would bekept identical throughout the 10 floors. Consequently, theshop detailing cost represented less than 1% of the totalsteelwork cost. However if changes were made such ashaving different end connection on some members, chang-ing penetration sizes throughout the floor and betweenfloors, the cost of shop details could increase to about 5%of the total steel cost.

The plenum height is influenced by a variety of factors suchas the depth and layout of the mechanical services, thedepth of the beam/slab at beam notches and the depth ofthe lights. Even though some beams were increased indepth in Design B, it would not generally require a greaterplenum height than Design A.Therefore facade costs werenot included in the cost comparison. Also, crane costs havenot been included since for this type of project the crane isnormally provided by the builder.

4.3 Case Study No 3. – 34.5 m spanBridge

The structures used in the previous examples havesignificant repetition and similarity between projects andhence industry rates could be developed. This commentparticularly applies to site activities. Accordingly for morecomplex projects, or for projects with less repetition, thepublished rates may need to be supplemented with ratesdeveloped from first principles. A simply supportedskewed bridge spanning 34.5 metres is used to demon-strate the application of the method.

4.3.1 Bridge DesignThe bridge is shown in Appendix D3 and is skewed at 15°to the road alignment. The bridge spans 34.5 metres witha width of 12.6 metres and consists of four composite plateI-beams, each weighing approximately 25 tonnes, at aspacing of 3.5 metres. Grade 350 steel has been adoptedfor the top flange and as the bridge is designed in accor-dance with Victorian conditions, Grade 350L15 has beenused for the bottom flange. The web is Grade 250. Theplate lengths were chosen to minimise the number ofsplices within the length of the beam. The concrete deck iscomposed of precast formwork acting compositely with theinsitu concrete.

The surface treatment specified for the project was Class2.5 blast together with 75µm of inorganic zinc silicate. Thishas been found to provide a very good life as well as beingan economical solution.

4.3.2 Costing Of The BridgeAppendix D3 shows the estimated costs of the supply, fab-rication, surface treatment and erection of the beams,intermediate and abutment cross frames.

(a) Steel SupplyThe areas of plate and the lengths of sections were calcu-lated and the appropriate rates applied. During this processthe various length, width and thickness combinations ofplates were investigated to minimise the number of weldedsplices and ensure the required combination was available(Refer Appendix B). For bridges, it is usually necessary toorder the required combination rather than rely on standardplates which have a maximum length of 12 metres and aremainly available in Grade 250. A smaller range of Grade350 standard plate is also stocked by distributors.

A 5% wastage factor was allowed for trimming the platesand for the waste involved in profiling the web to provide thespecified camber. This could have been refined by investi-gating in more detail the exact size of plates required.

(b) Fabrication The fabrication costs of the beams and cross frames werequickly and simply obtained from the relevant tables. Themass per metre of the beam was greater than given in thetable for the fabrication of gussets (or stiffeners). After con-sultation with some fabricators, it was agreed that the high-est rate in the table would be appropriate.

Bridge design drawings generally contain sufficient infor-mation so that shop drawings are not required.

The transport of the 35 metre long beams required specialconsideration as they were significantly over length andwould therefore require pilot vehicles and semi trailers withsteerable rear bogies. A specialist transport company wascontacted and it was determined that it would be feasibleand most economical to transport two beams and thecross bracing per truck. It was also determined that oneload would be scheduled per day. A budget price was thendeveloped and used as the basis of costing.

(c) Surface TreatmentThe surface areas were readily determined and the appro-priate rates for inorganic zinc silicate applied.

(d) ErectionA layout of the site was prepared and it was determinedthat it was necessary to lift 25 tonnes at a radius of 20metres. A number of crane hire companies were then con-tacted to determine suitable mobile cranes. A 150 tonnecrawler crane was required to enable a single crane lift. Forsuch large cranes the mobilisation and demobilisationcosts form a large component of the total cost of the erec-tion where there is a small number of members to be liftedinto place. It was determined that the crane would berequired to be on site for a total of a week. A rigging crewof 3 was allowed.

(e) Accuracy of estimateTo confirm the accuracy of the method and rates, a num-ber of fabricators were asked to price the bridge. Detailedpricing by the fabricators was found to be in close agree-ment with those given in Appendix D3.

4.3.3 Comparison With Traditional DesignThis method allows the designer to assess the impact ofdifferent structural arrangements to be determined withaccuracy. For example the beam spacing of 3.5 metres iscompared with the traditional spacing of steel beams of 1.8to 2.5 metres (Rapattoni (19)). The reduced spacingincreased the number of beams from 4 to 6.

Haywood (20) indicates the steel quantity would be slight-ly increased with the traditional beam spacing. AppendixD3 illustrates that the fabrication, surface treatment andtime related erection cost are proportional to the number ofbeams. Therefore the cost of these items would increaseby approximately 50%. This would increase overall cost ofthe steelwork for the bridge by about 20%.

5. APPLICATION OF METHOD ATDIFFERENT STAGES OF PROJECT

5.1 Stage 1 – Pre-design CostingAt this stage of a project the information is often verysketchy and the aim of the study is to determine whetherthe project is worth proceeding with. Therefore the inputsare the variables affecting the cost and revenue from theproject. For example on an office development the keyvariable is the amount of floor space. Hence it is impor-tant to have reliable costs per square metre of officespace.

These costs can be derived from previous projects usingthe methodology presented in Section 3. A database fromprevious similar projects would allow this information to bebuilt up. Perara and Bennett (21) reviewed methods ofmodeling data from previous projects to predict the cost ofthe project. The models can be categorised as threetypes: Parametric Cost Models, Regression Models, andProbabilistic Models.

There are also public sources of such information pub-lished on a regular basis such as Cordells(13) andRawlinsons(14).

A number of pre-design rates for industrial buildings, officeand retail floors are given in Appendix E.The order of accu-racy of estimate at this time would be ±20%.

5.2 Stage 2 – Indicative CostingOnce a layout is prepared, no matter how preliminary, themethod of costing proposed in Section 3 can be applied.Initial sizing can be based on experience, previous similardesigns, or design aids such as those given in Appendix E.The types of connections will be generally known at thisstage.This can be as general as whether the connection isrigid or pinned.

The accuracy of the estimate can be improved when thepreliminary sizing is undertaken by the structural engineer.This step is necessary when the team has limited experi-ence with a particular form of construction. Design aids toassist in the preparation of preliminary sizing include:

• Design Capacity Tables (22)(23) for steel members

• Steel Construction Journal December 1995 (24) forcomposite members

• Portal frame design guidance and charts (25) (26)

• Composite Steel Highway Bridge design guidance andcharts (20).

All non-standard connections should be reviewed toensure that practical connections can be developed.

The supply of bolts, cleats and wastage at this stage canbe allowed for by applying a percentage increase on themain steel members. It is suggested that 5% be allowed forsimply supported construction and 10% for continuousconstruction.

The order of accuracy at this stage is ±10%.

5.3 Stage 3 – Detailed CostingAt the end of the detailed engineering, all the information isavailable to accurately (±5%) determine the cost of thestructure using the method. This is illustrated in the casestudies (Section 4 and Appendix D). During all stages ofthe design, considerable benefit to the project can beobtained by having detailed discussions with the fabricatorand other specialists. The proposed costing methodassists in this by providing a common language for all pro-ject participants.

5.4 TenderThe new method will greatly assist the fabricator, in com-parison to the current method, during the tender processas it is presented in a form that assists preparation of thetender. The time taken for the preparation of the Bill ofQuantities is the same as that for the current method, asthe new method doesn’t significantly change the processof taking off the quantities, instead it changes the way theinformation is presented. For the full benefit to be obtainedfrom the new method, the Bill of Quantities must form partof the contract. This in the longer term will lead to signifi-cant savings for the client as it will substantially reduce thecost of tendering.

5.5 Cost Control Including VariationsAs the method is activity based, it lends itself to controllingcosts during a project. It allows the cost of variations to beeasily determined and has been used successfully on anumber of projects to help resolve disputes on variations.This saves a considerable amount of time and thereforecosts, in administering a contract.

6. STANDARD METHOD OFMEASUREMENTS

The Victorian Fabricators Sub-Committee of the AustralianInstitute of Steel Construction (27) have developed a draftrevision for amending the SMM5 (12) to incorporate thenew method. This has been trialed on a project and foundto be very workable. As it largely involved changing the pre-sentation of the document rather than fundamentallychanging how quantities are taken off, it took the sametime as preparing a conventional bill.This document is cur-rently being circulated for industry comment prior to mak-ing a formal submission on changing the standard.

The Australian Standard AS 1181 (11) was issued in 1982and gives only limited guidance for steel construction. It istime that consideration be given to updating this standard.

7. COMPUTERISATIONDuring the development of the costing method, spread-sheets have been used extensively to assist in quickly eval-uating different options. Spreadsheets have the advantagethat they can be simply modified to suit a particular pro-ject’s requirements.

Two different sets of proforma sheets have been used inAppendix D. These may be used as a template for spead-sheets or for manual calculations. The first set (AppendixD1 and D2) is suitable where there is a large number ofmembers in the structure and relatively little work permember. The second set (Appendix D3) is suitable wherethere are relatively few members, but with a significantamount of work on the members. The second proformasheets may also be used to develop costs for more com-plicated members and the results then fed into the first setof sheets.

At the more sophisticated level a number of database sys-tems (eg. Costcalc, WinEst Pro) are in use in the largercompanies. Discussions with the vendors indicate thatthese systems can be relatively easily changed to accom-modate the new method of costing.

One interesting development is the linking of design anddrafting systems into costing systems.There are a numberof instances where the Computer Aided Drafting Systemhas been linked to the costing system. This saves a con-siderable amount of time, but probably more importantlythe number of errors.

8. CONCLUSIONSA rational new approach has been presented which hasbeen shown to give improved reliability and accuracy incosting steelwork. It provides a common language that canbe used by all participants at every stage of the design andconstruction of the structure.

The new approach is based on dividing the costing exer-cise into four components:

• Steel supply - cost per metre for sections

- cost per square metre for plate

• Fabrication - cost per item of work

• Surface treatment - cost per square metre of treat-ment

• Erection - cost per lift.

The method has been shown to be simple to apply at allstages of a project from pre-design, design, tenderingthrough to contract administration. It has proven to providea valuable tool in the economical design and constructionof steel structures.

APPENDIX A1: STEEL SUPPLY COST

General Notes:1) The rates given include distributor’s and fabricator’s margins but do not include an allowance for wastage. Typically,

wastage allowance varies between 2 - 5 %.

2) The base grade of hot rolled steel and welded sections is readily available ex-stock from distributors.Higher grade steel must be specifically ordered (typical lead time – 8 weeks) and is subject to minimum order quantities.For standard lengths and widths refer to Appendix B.Subject to minimum order quantities and lead times, steel may be ordered to a specific length.This can be useful when the wastage would otherwise be high.

3) Hollow Sections are readily available ex stock from distributors.Non standard lengths must be specifically ordered (typical lead time – 5 weeks).

For standard lengths and widths refer to Appendix B.

4) Purlins & Girts are readily available cut to specified length.Coating Class Z450 is subject to minimum order quantities.

APPENDIX E2. STEEL FLOOR BEAM COSTS AT INDICATIVE COSTING STAGE

This appendix presents the results of steel designs prepared for carpark, office and retail centre floors, using the typicalbeam arrangement as depicted in figure E2.1. The results are intended to provide a guide during the assessment ofpreliminary design options (such as framing system or column layout) and early cost estimation. The costs charted areassociated with the primary and secondary floor beams only and include steel supply, detailing, fabrication, surfacetreatment, transport, cranage, erection and shear studs. Costs of notches or penetrations which might be required toaccommodate services are not included. Table E2.2 is a guide to the additional costs per sqm for the steel decking andreinforced concrete slab. The costs allow for fabricator margins.

The beams were designed according to AS2327.1 (1996) (Composite structures – Simply-supported beams) and arestandard BHP universal or welded beams of Grade 300 steel. Beams were assumed to carry uniformly distributed loading,were connected using AISC web side plate or flexible end plate connections and propping was not used. A selected set ofbeam design results is reproduced in Table E2.3.
